Method and device for generating user-specific feedback teaching content, in which a server performs the following steps: receiving execution data sets from a learning pool comprising a plurality of learners and storing the execution data sets in a database of the server; Providing a list comprising a number of entries to a teaching pool which comprises a number of teachers, with each entry in the list being assigned to an execution data record of the execution data records; detecting a selection made by a first teacher of the teaching pool of a first entry in the list and sending a first execution record associated with the first entry in the list to the first teacher.

Description

The invention relates to a method and a device for generating user-specific feedback instructional content.

Online services have greatly increased the scope and ease of conducting communications between two or more entities. Private and business content exchange is increasingly taking place via the exchange of electronic data. This also affects more and more areas in which the exchange concerns sensitive and detailed topics - e.g. training courses, court hearings, university examinations or the like. An exchange via online services now allows a high-quality exchange of content between entities, especially in situations where a physical meeting of the entities is not possible or should be avoided.

As the possibilities for real-time communication via online services such as instant messaging services, which enable chats and/or video calls, have increased, so too does the transmission of information through the provision/viewing/listening of pre-recorded videos or audio content, podcasts, etc.

Especially at times or under circumstances in which a gathering of several people (hereinafter also referred to as entities) should/must be avoided, the communication options described are often the only way to transmit teaching content/learning content or the like. Recently, this meant that even school or school-like lessons could only be carried out via the online communication options described by exchanging electronic data. Likewise, sporting or sport-like education/training was sometimes carried out entirely online.

A disadvantage of the known methods, however, is that the important and necessary personal and physical contact between teachers and learners often cannot be represented by the known electronic services described above, particularly in education/education/training areas.

In particular, a school training course or a training session for people involved in sports, for example a team sport, can only be imitated inadequately by the known electronic services. Didactic problems always arise when a teacher (i.e. trainer, teacher etc.) wants to train a group of learners (i.e. athletes, students etc.) as a whole in their abilities, but not the training of each individual this group of learners may neglect.

For example, teaching content relating to a team sport, such as soccer, can only be imitated inadequately by a teacher through a video conference. There are a number of learners and one or more teachers in a virtual conference room. The training content presented by the teacher always reaches all participants (also called entities) of the video conference at the same time. Training (i.e. imparting teaching content) to the team as a whole (i.e. all learners together) may represent or replace the real training with the physical presence of the entities to some extent. However, individual training or individual teaching of a teaching content for a single learner is hardly possible electronically. In addition, the success of the training is impaired by the fact that training is only possible if the learners and the teacher are in the virtual conference room at the same time and are actively participating in the video conference.

Furthermore, training a team as described above in the form that the learners perceive teaching content in video/audio/text form previously recorded by a teacher cannot adequately reproduce many teaching content. Training only takes place to the extent that a respective learner teaches himself the training content in an autodidactic manner. Furthermore, there is no individual feedback from the lecturer to the lecturer. Errors in execution are often overlooked by the learner, which slows down or even prevents the desired learning progress.

A disadvantage of the known methods is that the training of a large number of learners with the possibility of feedback/improvement to individual learners can only be inadequately reproduced technically using the known electronic possibilities. In particular, an efficient assignment of instructional content and/or feedback content to individual entities is not possible.

One object of the present invention is therefore to convey teaching content to the learners in a user-specific manner and in particular to enable user-specific feedback by teachers.

• Empfangen von Ausführdatensätzen von einem Lernpool umfassend mehrere Lernende und Speichern der Ausführdatensätze in einer Datenbank des Servers;
• Bereitstellen einer mehrere Einträge umfassenden Liste an einen Lehrpool, der mehrere Lehrende umfasst, wobei jeweils ein Eintrag der Liste einem Ausführdatensatz der Ausführdatensätze zugeordnet ist;
• Erfassen einer durch einen ersten Lehrenden des Lehrpools vorgenommenen Auswahl eines ersten Eintrags der Liste und Senden eines ersten Ausführdatensatzes, der dem ersten Eintrag der Liste zugeordnet ist, an den ersten Lehrenden.

According to one aspect of the invention, the object is achieved by a method for generating user-specific feedback teaching content, in which a server carries out the following steps:

• Receiving execution records from a learning pool comprising multiple learners and storing the execution records in a database of the server;
• providing a list comprising a number of entries to a teaching pool which comprises a number of teachers, with each entry in the list being assigned to an execution data record of the execution data records;
• detecting a selection made by a first teacher of the teaching pool for a first entry in the list and sending a first execution data set associated with the first entry in the list to the first teacher.

The method according to the invention makes it possible to generate user-specific feedback in a teaching/learning environment. The term "user-specific" means tailored/established/customized for or having properties for one or more users. In particular, a user can be any person who takes part in the teaching/learning process that is carried out on the server. In particular, users can be teachers and/or learners.

The term "teacher" includes people who have knowledge or skills in a way that they are able to impart to other people. In particular, these are trainers of sports, teachers of school-like knowledge content or the like. Also included are all types of people who impart instructions in the leisure sector or hobby-like area, for example also people who can impart make-up/furnishings/handicrafts/do-it-yourself/craft content. Embodiments of the method according to the invention can be used in sports (team and/or individual sports) - for example soccer training, basketball training, gymnastics training, tennis training and much more. The method according to the invention can also be used in school teaching/learning.

The term "learners" refers to persons who have received knowledge/skills or the like from one or more teachers of the type described above. A teaching content according to the invention comprises knowledge/skill content which is conveyed by one or more teachers to one or more learners.

Feedback teaching content refers to teaching content in which a teacher not only shows a learner how a certain activity is to be carried out, but also how the activities carried out by the learner are perceived, assessed and/or evaluated by the teacher. The teacher thus gives the learner feedback (feedback) on their performance of activities to which the learner has instructed them, for example.

According to the invention, one or more teachers are combined in a teaching pool and one or more learners are combined in a learning pool. Such a pool includes a number of teachers or learners who take part in the teaching/learning/feedback process in a manner known to the server and are in a data exchange with the server. For example, in the case of soccer training, the learning pool can include people who are interested in soccer training and have different soccer skills. In such a case, the teaching pool could include one or more football coaches, possibly with different qualifications. For the server performing the method, the (soccer) players are combined in the learning pool and the (soccer) trainers in the teaching pool.

The server provides functionalities, utilities, data and/or resources so that one or more teachers and one or more students can interact with each other. Each of the teachers/learners has a correspondingly adapted device in order to be able to communicate with the server via a network, i.e. to be able to send data/data sets or the like to the server and/or to be able to receive data from the server. The network enables the above-mentioned devices to be connected in order to enable communication between them and thus between their users.

The server includes a processor, that is, a functional unit for executing commands, programs, procedures, methods, etc., which are stored in a memory of the server. The server also includes a database for storing data, data sets or the like. Data refers to representations of facts, concepts, or instructions that are suitable for communication, interpretation, and processing. A record is a group of related data. In possible embodiments, the server can be a cloud server, a virtual server, a virtual private server, a cloud-based server and/or one or more logical units analogous to a server. Ent In other words, data can be distributed across multiple physical devices.

According to the invention, the server receives execution data sets from the learning pool, i.e. the server receives one or more different execution data sets from one or more learners. In this case, an execution data record refers to data/data records created by a learner's device, which can be sent to the server and interpreted by the server, for example a recorded execution of a teaching content by the learner. The execution data set can in particular be a data set of a recorded video which shows the learner performing an exercise - for example how the learner executes a shot of a soccer ball with the inside of a foot, how the learner executes certain shapes and figures (for example when applying make-up or when drawing geometric figures or when shaping a pottery object) or the like.

Each of these execution data sets is received by the server after being sent by the respective learner and stored in the database. The server creates, updates, and/or provides one or more lists, which are stored in the database. The list includes one or more entries, with each execution data record being assigned at least one or exactly one entry. Alternatively or additionally, multiple execution data records can also be assigned to an entry. After the server receives an execution record, an entry is created in the list or an existing entry is updated.

The server provides the list to one or more teachers and/or one or more students. According to the invention, several ways of providing the list are possible. The server can provide the whole list or only part of the list. The types of provision can also differ in terms of the extent to which a teacher can extract information from an entry. For example, the entries can be anonymized in such a way that a teacher cannot tell from an entry which execution data record this entry is assigned to. Alternatively, the assignment to the execution data record can be recognizable from the entry. In this case, the provision can also differ in the extent to which information about the execution data record can be extracted from an entry despite assignment. For example, an entry can indicate which learner created the execution data record, which execution can be seen from the execution data record, when the execution data record was created, whether the learner is an experienced or inexperienced learner and/or whether a learner has often participated in the has participated in the process according to the invention and/or has been evaluated by one or more teachers in the teaching pool.

The list and/or parts of the list and/or individual entries of the list are made available to the teaching pool in such a way that one or more teachers can select one or more entries from the list. A teacher can make a selection using a device (computer, smartphone, etc.). A selection by a teacher is communicated to the server by the device via a network. In the event that a (first) teacher selects a (first) entry from the list provided, the server determines the (first) execution data record which is assigned to the selected (first) entry in the list. This execution data record is sent from the server to the (first) teacher of the teaching pool who made the selection. The (first) execution record is an execution record that was sent to and received from the server by a (first) learner and stored in the database.

After a teacher has selected an entry from the list and/or after the execution data record associated with the entry has been sent from the server to the teacher, this entry is preferably removed from the list by the server. This ensures that an execution data record is only ever evaluated by one teacher and not by several, and a feedback data record is created in the manner described below. In a corresponding manner, the execution data record can also be automatically blocked for all teachers who are not the teachers who receive the selected execution data record from the server.

A particular advantage of the method according to the invention is that a server-side assignment of data records enables individual learners in a learning pool to be trained/instructed by one or more teachers in a learning pool without the physical presence of the persons being necessary. Furthermore, neither teachers nor learners are bound by local or temporal requirements/conditions.

• Ermitteln eines Zuordnungsgrades zwischen dem Entitätsdatenbezeichner des jeweiligen Ausführdatensatzes und dem ersten Lehrenden für jeden der Ausführungsdatensätze;
• Anordnen der Einträge der Liste gemäß den Zuordnungsgraden der den Einträgen zugeordneten Ausführdatensätze,
• Bereitstellen der Liste an den ersten Lehrenden, derart, dass die Einträge der Liste gemäß den Zuordnungsgraden angeordnet sind.

According to one embodiment of the method, it is provided that each of the execution data records comprises an entity data identifier; and that the server does the following:

• determining a degree of association between the entity data identifier of the respective execution record and the first teacher for each of the execution records;
• arranging the entries of the list according to the association degrees of the execution data sets associated with the entries,
• Providing the list to the first teacher in such a way that the entries in the list are arranged according to the degree of assignment.

Thus, each execution record includes one or more identifiers. This is an identifier that uniquely names a property of a data set (here, for example, the execution data set). An identifier is preferably unique within a namespace that the server can understand. In particular, an execution record includes an entity data identifier. Entity data is data that identifies a learner and/or teacher. In this way, the entity identifier of an execution data record can be used to obtain the information as to which learner created the execution data record comprising this entity identifier and/or to which learner this execution data record relates.

For example, if the execution record is a video showing a student kicking a soccer ball with the inside of his foot, the execution record of that video showing that kick includes an entity data identifier that uniquely identifies the teacher who performed the executes the inside shot shown. Similarly, the entity data identifier may uniquely identify the learner who draws/sculpts a geometric shape in a video, for example (e.g., when applying makeup, teaching geometry, making pottery, or performing a figure in floor exercise, or the like).

The server can use the degree of association to order the entries in the list (specific to the teacher/learner). The server thus creates an arranged list from the list, or changes the list in such a way that an arranged list results from this by arranging the entries. The arrangement is carried out based on the degree of association between the entity data identifier of the respective execution data record and the (first) teacher. As a result, a specific ordered list is created for each teacher. This specifically ordered list is provided to the teacher in place of, or in addition to, the unordered (or original) list.

In one possible embodiment, the degrees of association relate to the number of feedbacks that the first teacher has previously given to the learner identified by the entity data identifier. Accordingly, the entries in the list assigned to the execution data records are sorted in such a way that execution data records of the learners identified by the respective entity data identifier, which were often evaluated by the first teacher in the past, are higher up in the list. Optionally, it can also be displayed for each entry in the list how many feedbacks and/or feedback data records have already been created by the (first) teacher for the learner identified by the entity data identifier in the past.

In addition or as an alternative, the degree of assignment and thus the sorting of the list can be designed in such a way that specific qualifications of the teachers and/or a specific skill/performance level of the learners are taken into account. For example, higher-skilled coaches (e.g., B vs. C-coaches) and professional/recreational soccer players can each be matched using the mapping described above such that higher-skilled coaches and professional players receive a higher degree of attribution than higher-skilled coaches and recreational players. As a result, under this type of association, a list is made available to a first (higher qualified) teacher, for example, in which the executable files of professional players are listed higher up than those of hobby/amateur players.

The list can be arranged according to one or more sortings and/or sub-sortings. For example, several and different degrees of association between entity data identifiers and a (first) teacher can be determined and these one or more degrees of association can be used to arrange the entries in the list. Additionally or alternatively, the entries in the list can be sorted according to ascending or descending date of receipt.

In addition or as an alternative to the embodiments explained above, degrees of association between the execution data records and the first teacher can also be determined based on an evaluation of certain properties of execution data records that the first teacher has previously selected, with a higher degree of association being determined if an execution data record with regard to the properties corresponds to the execution data records previously selected by the first teacher.

The relevant properties preferably include properties that are common to the execution data sets previously selected by the first teacher. These can be determined, for example, by one or more entity data identifiers and/or content data identifiers. To determine the properties methods of artificial intelligence and/or machine learning can be used. Using such methods, patterns can be recognized automatically, for example regarding age, level of knowledge/skills and/or level of experience of the respective learner and/or teacher. The list and/or parts of the list can then be created or adapted in a teacher-specific and/or learner-specific manner for a specific teacher. The server can thus decide user-specifically whether and/or at what position an entry in the list is displayed for a teacher.

• Empfangen eines Anleitdatensatzes betreffend einen Lehrinhalt von einem zweiten Lehrenden des Lehrpools und Speichern des Anleitdatensatzes in der Datenbank;
• Senden des Anleitdatensatzes an den ersten Lernenden und/oder an den Lernpool.

A further embodiment of the method provides that the server continues to carry out the following steps:

• receiving an instructional record relating to instructional content from a second instructor of the instructional pool and storing the instructional record in the database;
• Sending the instruction data record to the first learner and/or to the learning pool.

In order to further technically expand the didactic possibilities of the method carried out by the server, in this embodiment each of the teachers in the teaching pool can preferably create instruction data sets that relate to a specific teaching content. Each of these instruction data sets, created for example by a second teacher, is received by the server and stored in the database. The second teacher can be the first teacher or another teacher.

The server is able to send one of the instruction data sets to one or more learners in the learning pool at any time. This can occur, for example, when one or more learners want to take part in a specific training course/lesson. For example, a (learner) interested in soccer can request the server to send him a specific instruction data record. The learner's device converts the instruction data record into a form that the learner can perceive, so that the learner can perceive instructions from the (second) teacher. For example, a soccer coach can use the instruction data set to show the trainee how, for example, an inside shot with a soccer ball is to be carried out. For example, the learner can watch the video showing the second teacher performing the inside shot (and from which the instructional data set was created). After the learner has perceived the instruction data or with the help of it, the learner can now create an execution data record, for example create a video himself, which shows the learner performing the respective activity (for example inside shot).

• Empfangen eines Feedbackdatensatzes von dem ersten Lehrenden des Lehrpools und Speichern des Feedbackdatensatzes in der Datenbank;
• Senden des Feedbackdatensatzes an den ersten Lernenden und/oder an den Lernpool.

One embodiment of the method includes the server also carrying out the following steps:

• receiving a feedback record from the first instructor of the teaching pool and storing the feedback record in the database;
• Sending the feedback record to the first learner and/or to the learning pool.

Just as a learner can react to a teacher's instruction data set by means of an execution data set, a teacher can react to a learner's execution data set by means of the feedback data set. In this respect, provision is made for each of the teachers in the teaching pool to be able to create feedback data records that provide feedback in response to an execution data record of a learner's execution. Each of these feedback data records, created for example by the first teacher, is received by the server and stored in the database.

As described below, the server is always able to send one of the feedback records to a learner in the learning pool. The learner's device converts the feedback data set into a form that the learner can perceive, so that the learner can perceive the feedback from the (first) teacher. For example, a soccer coach can use the feedback data set to give the learner feedback as to whether, for example, the execution of an inside shot with a soccer ball by the learner in the execution data set was carried out correctly or requires improvement. To provide feedback, the teacher can, for example, watch the video showing the learners performing the inside shot. After perception of the execution data by the teacher or with the help of it, the teacher can now create a feedback data set. The learner can watch the video of the feedback data set and thereby receives feedback specific to him/her (i.e. user-specific).

The instruction data set, the feedback data set and each of the execution data sets can each be a video file and/or an image file and/or an audio file. Content is recorded by means of video, image and/or sound and transmitted by a teacher and/or learner to other learners and/or teachers using the server within the relevant data record. For example, an instruction data record can result from a recording in which a (first) teacher shows how an inside shot, certain make-up steps, certain geometric shapes in mathematics lessons, shapes in pottery, certain movements in gymnastics, or similar are to be carried out. These instructions are transmitted to one or more learners, for example after being asked, so that they carry out corresponding activities in accordance with the instructions and record them in a video, image and/or audio signal that is stored in an execution data record. This can be transmitted to the first and/or other teachers via the server.

After receiving an execution data record, a teacher can now evaluate, comment on, edit, etc. the execution shown in order to give feedback. Any kind of such feedback is created visually, auditory and/or in text form and sent to the learner from whom the execution data record originates via the server and the network and thus played back. Through the communication between learners and teachers by means of an instruction data record, feedback data record and execution data record, training/instruction etc. can be carried out which is location- and time-dependent and does not require the simultaneous physical presence of learners and teachers.

In order to use the storage resources of the server efficiently while at the same time optimally aligning the feedback with the needs of the learner, the feedback data set can comprise the video file, image file and/or audio file of the learner's execution data set and an overlay data set. In this embodiment, the evaluating/feedback-giving (first) teacher only adds the overlay data record to the execution data record. Thus, only the overlay data record has to be stored in the database in addition to the execution data record and not a complete, independent feedback data record. The overlay data set can in particular include overlay video data, overlay image data and/or overlay audio data.

According to the invention, the overlay data set can be the data of a processing of the video, the images and/or the auditory content of the execution data set, with this execution data set now being superimposed by the teacher using an overlay comprising video data, image data and/or audio data and/or or being edited. For example, if the execution data set relates to a video that shows the learner executing an inside shot, a teacher can edit the execution data set and create the feedback data set from it in such a way that the video is overlaid with graphic elements, for example. For example, the teacher can insert image/text elements or spoken elements that specifically indicate an incorrect foot position on ball contact.

In addition or as an alternative, a feedback data record or parts of a feedback data record can be assigned to a group automatically and/or by the teacher. In such groups, possible errors can be grouped in different abstractions - for example, in football, errors relating to posture, supine position, foot position, weight load, body orientation or the like. Such a grouping, for example according to punctual or selected errors, enables a versatile system improvement. In particular, a learner who has created the execution data record, for example, can be offered specific further learning information based on his mistakes and/or the corresponding group, for example information in visual, auditory and/or text form and/or, for example, specifically to avoid lying on his back. In addition or as an alternative, clustering can be used for self-learning of the system within the framework of machine learning. With the help of known and described methods of artificial intelligence, the system is trained in such a way that future feedback requests are matched between learners and teachers on the basis of the (error) cluster. In particular, teachers can be chosen who specialize in problems with, for example, lying on their backs in football.

One embodiment of the method provides that the instruction data set, the feedback data set and/or one or more of the execution data sets each include a content data identifier, with the server determining a first execution data set group that includes execution data sets for which the content data identifier of the respective execution data set corresponds to the content data identifier of the Guidance data set corresponds, and wherein the list comprises only the entries that are assigned to the execution data sets of the first execution data set group. The content data identifier can in particular indicate a content topic of the video file, the image file and/or the audio file. In the example of football, this can be a specific shooting or defense technique, a specific tactical game behavior or something similar.

Since both the instruction data record and the execution data record include a content data identifier, the list provided to the first teacher can, for example, be filtered in such a way that only entries are displayed whose associated execution data records include a content data identifier that is identical to a content data identifier of an instruction data record. This enables a technically efficient assignment of instruction and execution, namely by creating a grouping of only the execution record sets pertaining to a certain topic/instructional content (determined by the content data identifier of the instruction record). For example, a primary teacher who is interested in some instruction, for example, on inside shots in defense (and a specific instruction record for that), can have the server display only the execution records that result from learners' explanations of inside shots in defense.

Alternatively or additionally, the list can also be filtered in such a way that only entries are displayed for which the respective entity data identifier of the execution data record assigned to the entry satisfies a predetermined condition. For example, a teacher can request that he only be shown execution records from learners who have received at least a certain number of feedback records and thus feedback on their executions. To do this, the server checks whether an entity data identifier meets this condition and only includes the entry of the associated execution data record in the list provided to the teacher if the condition is met.

Furthermore, one embodiment of the method is characterized in that the instruction data record and/or the feedback data record includes an entity data identifier, and the server determines whether the feedback data record is to be checked as a function of the entity data identifier of the feedback data record and/or the entity data identifier of the instruction data record. The entity data identifier of a guidance or feedback data record is implemented in a similar manner to the entity data identifier of an execution data record and indicates the teacher from whom the server receives the respective execution or feedback data record. A connected embodiment provides that the server sends the feedback data set to a third teacher for checking if the feedback data set is to be checked, and the server sends the feedback data set to the learning pool if the feedback data set is not to be checked or if the control of the feedback data set has been made by the third teacher and the feedback data set has been released by the third teacher.

In addition or as an alternative, a variable (for example a random variable) can identify a random check of the instruction data record or feedback data record as necessary. The variable can also indicate that, for example, within the chronological sequence of the instruction and/or feedback data records created by a teacher, there is a specific number of data records between the data records to be checked. In this way, for example, every fifth data record of a teacher can be checked. The number 5 is only to be understood as an example and can be replaced by any natural number.

Additionally or alternatively, the variable can be a static number or a number based on statistical methods. Probability distribution, expected value, variance, standard deviation and/or confidence interval are taken into account. As described below, for example, a feedback data set is checked more frequently by a teacher who is new to giving feedback and/or by a teacher whose feedback data sets have already been rejected once/multiple times after checking. For a group consisting of such teachers, more frequent and/or stricter controls can be implemented.

The control, which can be carried out by a third teacher, if necessary, according to the aforementioned configurations, makes it possible for a feedback data record and/or an instruction data record to be sent to the teaching pool again in advance before it is sent to a learner and/or the learning pool more precisely to a teacher or his device who has not created the respective feedback data record and/or the instruction data record. Depending on an entity data identifier recorded in the respective data record or on a variable, the server decides whether a control of the respective data record is to be carried out. For example, the server can recognize that a teacher identified by the entity data identifier is newly taking part in the giving of feedback, and thus the first (for example ten) feedback data sets and/or instruction data sets should be subjected to a check. In addition or as an alternative, a teacher can also be classified based on historical experiences regarding the giving of feedback in such a way that a check is carried out for each data set of this teacher.

If the determination by the server shows that a check is necessary, the server sends the feedback data set and/or the instruction data set to another teacher for checking, which means that the teacher checks the instruction data set and/or feedback data set. The control can relate to the technical quality of the respective data set itself and/or the quality of the content on which the data set is based. The selected third teacher who carries out the control can be, for example a higher qualified teacher (than who created the respective dataset and sent it to the server), or peer control can take place. After a check has been carried out, the third teacher sends the checked data set back to the server and preferably also sends information as to whether the respective data set is approved or rejected after the check. The feedback data record and/or instruction data record is only sent to the learning pool and/or one or more learners if the third teacher has given their approval.

• Senden des Feedbackdatensatzes an den ersten Lernenden und/oder - nach Erhalt einer Freigabe des Feedbackdatensatzes und/oder nach Erhalt einer freigegebenen Bearbeitungsversion des Feedbackdatensatzes von dem ersten Lernenden - Senden des Feedbackdatensatzes und/oder der freigegebenen Bearbeitungsversion des Feedbackdatensatzes an eine erste Community-Gruppe,
• wobei die erste Community-Gruppe umfasst: die Lernenden des Lernpools und/oder die Lehrenden des Lehrpools, für die der ersten Lernende den Feedbackdatensatz freigegeben hat.

A further embodiment of the method provides that the sending of the feedback data record to the learning pool includes the following steps:

• sending the feedback data set to the first learner and/or - after receiving a release of the feedback data set and/or after receiving a released edit version of the feedback data set from the first learner - sending the feedback data set and/or the released edit version of the feedback data set to a first community group,
• wherein the first community group includes: the learners of the learning pool and/or the teachers of the teaching pool for whom the first learner has released the feedback data record.

Furthermore, one embodiment of the method comprises that the server sends the first execution data set and/or the released edit version of the execution data set to a second community group after receiving a release of the first execution data set and/or after receiving a released edit version of the execution data set, the second community The group includes the learners in the learning pool and/or the teachers in the teaching pool for whom the first learner has released the first execution data set.

The aforementioned embodiments are characterized in that, in addition or as an alternative, a feedback data record, an execution data record and/or an edited version of one of these respective data records is sent from the server not only to the first learner, but also to one or more other learners in the learning pool . Upon receipt of approval by the learner for whom the feedback record is intended, or who created or submitted the execution record to the server, the server sends that record, or an edited version of that record, to a first or second community group , which includes the learners of the learning pool and/or the teachers of the teaching pool for which the first learner has given approval.

The edited version of a record is the feedback record and/or the execution record that has been additionally edited by a specific learner. The edited version of the respective data set can be created, for example, by combining certain parts of the instruction data set, the feedback data set and/or the execution data set. For example, videos can be placed next to/on top of each other, audio tracks can be supplemented and/or expanded, or graphic and/or text and/or image elements can be inserted. Furthermore, processing can also include, for example, cropping and/or cutting out of text/image/auditory elements. For example, a learner can crop a video from the sides to create a larger format image.

The above-mentioned embodiments of the method thus enable the respective teacher to create a detailed version of the learning/teaching content that has been adapted according to his wishes and supplemented with information and to make this available to certain members of the learning pool and/or the teaching pool after approval. In this respect, a learning effect does not only take place through instruction and feedback from the teachers, but also through mutual monitoring/motivation among the learners. This comes very close to training, for example in team sports, with all its advantages. Furthermore, this training can take place independent of location and/or time and without any physical contact.

All of this is achieved according to the invention by a technical, intelligent and not obvious execution by the server, including the storage and mutual assignment of the respective data records and specific identifiers in the corresponding data records. This implementation requires a deep technical understanding of how data sets are constructed, how data sets can be mapped, and how data sets can be represented and processed.

Moreover, one embodiment of the method is characterized in that the server, upon receipt of the execution data records from the learning pool, determines whether the respective execution data record includes a defined format and requests a re-transmission of the respective execution data record from the learner of the learning pool from which the respective execution data record was received , if the respective execution record does not include the defined format.

The defined format can be a format of a video and/or an image of the video file and/or image file on which the execution data record is based. In one possible embodiment, this relates, for example, to whether one or more images are in landscape format or portrait format. In addition or as an alternative, the defined format can include a form of coding for the video, image or audio data of the data set. In the embodiment mentioned, the server determines for each execution data record whether it has the defined format. If this is not the case, the server automatically sends a request to the learner from whom the server received the execution data set to resend the execution data set to the server in the requested format.

The defined format can be dependent on an instruction data record, which is sent from the server to one or more of the learners in the learning pool. In particular, there may be a dependency on the (format of) the instruction data set in response to which the learner creates the execution data set. For example, it can prove to be advantageous when training header exercises in soccer that these are each recorded by means of a video in portrait format for the instruction data set and the execution data set. In this example, the server verifies that the video of the run record is in portrait orientation. If this is not the case, the server requests a retransmission of the execution record with a portrait video from the learner. The learner can then edit the existing video accordingly or recreate it in portrait mode and then submit the edited or recreated video to the server in a new run record.

The feedback data record can in particular include rating data, text data and/or translation data.

In a connected embodiment of the method it is provided that the translation data includes a language translation of the video file, the image file, the audio file, the overlay video data, the overlay image data, the overlay audio data, the rating data and/or the text data of the feedback data record, wherein a language of the respective language translation is determined by the server in dependence on the entity data identifier of the first execution data record. Based on the respective entity data identifier of the execution data record, the server recognizes which language is advantageous for the learner.

Furthermore, the teacher's feedback record created in response to the execution record may include the entity data identifier of the corresponding learner and the corresponding teacher. The server can then use the entity data identifier that specifies the teacher to recognize the language in which the feedback data set is created and, based on the entity data identifier that specifies the learner, determine which language translation is advantageous and create a translation file accordingly (e.g. subtitles) and this add to the feedback record. Consequently, the server sends the learner a feedback dataset that the learner can immediately understand linguistically, even if the learner and the feedback-providing teacher communicate using different languages.

The text data of a feedback data set can, for example, include written feedback from the teacher to the learner. For example, such feedback can explain in text form which aspects were not executed correctly for the execution data record and what the learner should pay attention to in future executions.

The rating data can, for example, rate the learner's statements in the underlying execution data record in the form of notes. Such a points/rating system offers an objective assessment and comparability. Such a rating can also be embedded in the text and/or language data of the feedback data record. The rating data are preferably designed in such a way that the server can interpret them. The server is then able to determine the rating specified in the rating data for each feedback data set received. On this basis, the server can create a comparison of the different contents of the rating file and/or the ratings. Such a comparison can, on the one hand, compare and contrast the skills of the various learners (based on the rating in the rating file) in the form of a list. Furthermore, a comparison of the different teachers can also be created by the server, which indicates (for example in the form of a list) whether certain teachers evaluate rather (too) positively or negatively or on average.

As explained, an execution data set, instruction data set and/or feedback data set comprises one or more entity data identifiers which are uniquely assigned to a teacher and/or a learner. A feedback data record can include both the entity data identifier of the teacher who created the feedback and the entity data identifier of the learner, who created the (underlying) execution record, and who receives the feedback. In general, a record includes the entity data identifier of the entity (learner or teacher) from which the server receives the record.

In one embodiment, a score parameter is associated with each entity data identifier. The evaluation parameter indicates a measure of the teacher's or learner's ability. For example, it may reflect the learner's ability to perform an activity in general. In addition or as an alternative, the evaluation parameter can evaluate a teacher in such a way that it indicates how the teacher generally gives feedback. It is advantageous if the teacher's evaluation parameter is adjusted depending on the comparison for the rating file. Additionally or alternatively, the evaluation parameter of a teacher can also be adjusted based on feedback received from the server by the learner who has received the feedback data set, i.e. the evaluation parameter of a teacher can also be adjusted to the extent that the server receives feedback from the learner , which received the feedback dataset, is taken into account. In this case, the teacher's evaluation parameter reflects the learner's satisfaction with, for example, the way in which the teacher gives feedback for the feedback data set in general. In one possible embodiment, the evaluation parameter can be data to which entries in a list, matrix, or the like are clearly assigned on the server side. are assigned - for example as a note (1, 2, 3, ...) or as a text (very good, good, satisfactory, ...).

According to an advantageous embodiment of the method according to the invention, it is further provided that the feedback data record comprises at least one element that is generated by the server depending on the entity data identifier and/or the content data identifier of the instruction data record and/or the first execution data record. The at least one element can include text data, for example, which is determined in particular using the entity data identifier and/or the content data identifier. This can be done on the basis of specifications and/or parts of a catalog of criteria that are tailored to what content/training elements are transported using the instruction data record and/or the execution data record.

For example, an instructional record can show the correct execution of an inside shot. As a result, the execution record shows a learner executing such an inside shot. In such a case, the server recognizes from the entity data identifier and/or the content data identifier that an inside shot of, for example, a hobbyist or professional learner is shown. Elements that are then generated by the server can be determined, for example, using predefined criteria for executing the inside shot - for example the position/load of the supporting leg/free leg/playing foot or the hitting area of the foot with the ball.

The at least one element can be generated depending on the entity data identifier and/or the content data identifier on the basis of information sent by the teacher, so that the teacher can give quickly and easily without already having to generate the element in question completely himself. For example, the text file covered by the feedback data set can contain the following text parts, which are generated by the server based on information from the teacher: "Hello, your knee load is satisfactory, but your body axis is good...".

According to a further aspect, the invention provides a computer program product to achieve the stated object, which includes a computer program with instructions that cause a server device to execute a method of the type described above when the computer program is executed on the server device.

1 Figure 1 shows a system 11 comprising a server 2 executing a method for generating user-specific feedback instructional content. The term user-specific includes teaching and/or learning adapted to users (one or more learners and/or teachers) with the inclusion of feedback. The server 2 comprises a processor 3, a memory 4 and a database 5. Methods or programs which the server 2 executes are stored on the memory 4. FIG. In the database 5, the server stores, in particular, various data sets that the server 2 receives from one or more learners and/or teachers. The processor 3 is designed in such a way that it carries out data processing. This includes editing/supplementing/changing etc. of data records.

The server 2 communicates via a network 4 with one or more students 7a, 7b, . . . and/or with one or more teachers 6a, 6b, 6c, . The one or more learners and/or teachers are also referred to herein as one or more entities. Several learners 7a, 7b, ... define a learning pool 7. Several teachers 6a, 6b, ... define a teaching pool 6. The bidirectional communication with the server includes receiving data and/or data sets from the server and sending them data and/or records by the server.

Each of the one or more learners and/or teachers has a device that makes it possible to communicate (bidirectionally) with the server via the network. The devices are each designed to present the data records of the method in a (user-friendly) representation to the one or more learners and/or teachers. Furthermore, the devices can preferably convert inputs from the one or more learners and/or teachers into a corresponding data set, which is then sent via the network 1 to the server and on to one or more other learners and/or teachers. For example, the device can be a computer, a mobile phone or the like.

The process carried out by the server is explained in more detail on the basis of 5 described. In an exemplary, simplified embodiment, the server 2 receives an instruction data record 8a from a teacher 6a. The server 2 stores the instruction data record in the database 5. In the event that, for example, a learner 7a is interested in a teaching content and sends a corresponding request to the server 2, the server 2 sends the instruction data record 8a to the learner 7a. The learner 7a perceives the content of the instruction data record 8a in a corresponding representation and creates (such as by means of the device) an execution record 9a in response thereto. The execution data record 9a is sent to the server 2 via the network 1 and stored by the server 2 in the database 5 . The server 2 assigns parts of the data records in the database to an entry in each case and creates a list comprising the entries in an order determined by the server 2 . The list is made available to one or more teachers 6a, 6b, 6c,...

After the teacher 6b has selected an entry, the execution data record 9a associated with this entry is sent from the server to the teacher 6b. The teacher 6b can now have the execution data set 9a displayed by his device in a corresponding display (view/listen etc.) and create a feedback data set 10b during and/or afterwards. The content of the feedback data record 10b includes feedback on the execution data record 9a using, for example, overlay elements such as an overlay video file and/or overlay image file and/or an overlay audio file. After completing the process of creating the feedback data record 10b, the teacher 6b sends a feedback data record via the network to the server 2 for storage in the database 5.

Depending on the entity itself and the history of the teacher 6b (or the assigned entity data identifier of the teacher 6b) and/or a variable (for example a random variable), the server 2 determines whether the feedback data record 10b needs to be checked. If it is necessary to check the feedback data record 10b, the server 2 sends the feedback data record 10b via the network 1 to the teacher 6c, who can approve or reject the feedback data record 10b. After feedback from the teacher 6c to the server 2 as to whether the feedback data record 10b is approved or rejected, the server 2 sends the feedback data record 10b to the learner 7a.

The 2a-2c show an instruction data set 208, an execution data set 209 and a feedback data set 210 each schematically. In the schematic view, each of the data sets 208, 209 and 210 comprises a video file 220, 230 and 230, respectively, in combination with an overlay data set 240 (overlay video file). Furthermore, the data records each include a content data identifier 221, 231 or 241. Each data record also includes at least one entity data identifier 222, 232 or 242. The respective content data identifier 221, 231 or 241 is assigned to a specific content topic. For more information refer to 4A and 4B explained below. The video file 220, 230 or the overlay data record 240 is designed in such a way that a teacher's and/or learner's device can display it in a form that the teacher and/or learner can perceive, for example using moving images and/or audio.

The feedback data set 210 created in response to the execution data set 209 comprises the video file 230 of the execution data set and the video file 230 supplementing/overlaying overlay video data 240. One embodiment of the possible editing of a video file 230 to create overlay data 240, or its/their Representation by a device of a learner and / or teacher is based on the 6A until 6D described.

The one or more learners and/or teachers with whom the server communicates bidirectionally in order to carry out the method according to the invention are registered in the server. Thus, the server can assign a (unique) entity data identifier 222, 232, or 242 to each of these one or more learners and/or teachers. In one embodiment, for example, an entity data identifier is assigned to an entity (teacher and/or learner) in such a way that the entity data identifier 222, 232 or 242 supplements the respective data record with the information from which entity the data record was sent to the server 2 and from which Server 2 is received. The existence of the entity data identifier thus offers the sever 2 the possibility of being able to extract the information from each data record as to the entity from which the respective data record originates or the execution of which entity is shown in the video of the video file.

The feedback data set may include the entity data identifier 232 of a learner 7a and the entity data identifier 242 of a teacher 6b. The server can thus obtain from the feedback data record 210 the information by which learner the execution data record 290 on which the feedback data record 210 is based was created (here learner 7a) and by which teacher feedback for the feedback data record 210 was created (here teacher 6b).

The inclusion of one or more identifiers such as content data identifiers and/or entity data identifiers enables the server to efficiently and user-specific sort and, in particular, assign different data sets in such a way that efficient guidance, execution and feedback for the users (teachers and/or learners) is possible.

3 shows schematically execution records 309a - 309f. Each of these execution records 309a-309f is associated with an entry. Each entry will be in presented in a list, which is provided to one or more teachers 6a, 6b, ... by the server. Each of the execution records 309a-309f includes one or more content data identifiers 331a-331f. The assignment of a content data identifier to a specific teaching content or how the server and/or a device of a teacher and/or learner recognizes or assigns a teaching content based on a content data identifier 331a-331f 4A , 4B and 4C described.

According to the invention, each instruction data record 8a also includes at least one content data identifier 221. The server can thus use the content data identifier 221 for a specific instruction data record 8a and compare it with one or more content data identifiers 331-331f of the execution data records 309a-309f. Consequently, only content data records (here 331b, 331d and 331f) that are identical to the content data identifier 221 relate to the same teaching content, which is comprised of, for example, the corresponding video file. In an advantageous embodiment, the server determines whether content data identifiers of execution data sets are identical to a content data identifier of a predetermined instruction data set.

For the execution data records 309b, 309d and 309f, whose content data identifiers 331b, 331d, 331f are identical to the content data identifier 221 of the guidance data record 208, a first execution data record group 309A is assigned.

In addition or as a supplement, a second execution data record group 309B can be formed in such a way that it contains only the execution data records 309b, 309f of the execution data records 309a-309f that meet a defined condition. The condition can be defined according to the requirements of the first teacher, for example. For example, (based on the first execution record group 309B or based on all execution records 309a-309f), the second execution record group 309B can only include the execution records 309b and 309f whose entity data identifiers 332b and 332f meet the conditions that they are associated, for example, with learners who, as a hobby, Execute teaching content, i.e. the execution data records 309b and 309f only come from teachers practicing as a hobby. Thus, the execution record group 309B may contain only the execution records of hobby learners who perform an inside shot at soccer (this is the learning content/content topic designated by the content data identifier 331b, 331f).

Since each execution data record is assigned an entry in the list, starting from the first execution data record group 309A and/or the second execution data record group 309B, the list can be reduced/filtered/adapted etc. in such a way that this list only includes the entries which are respectively assigned to the execution data records of the first and/or second execution data record group. In the present case, an execution record group is also referred to as an execution record group, execution record group or execution record group.

4A shows a possible embodiment of the invention, how a content data identifier 431 can determine a (teaching) content. The content data identifier 431 can be one of the content data identifiers 221, 231 or 241, which is included in one of the data sets 208, 209 or 210. In one possible embodiment, the content data identifier 431 can be assigned to an entry in a list or a (one-dimensional or multi-dimensional) matrix, and thus determine an entry of this.

According to 4A the content data identifier 431 designates an entry in a two-dimensional matrix A = a _i,j = a _ij . In the present embodiment, each row of the matrix A is assigned to a specific activity (sports/craft/school, etc.). In the present case, the first line is assigned to a sporting activity in tennis, the second line to a sporting activity in soccer, the tenth line to an activity in make-up, the eleventh line to an activity in pottery, the twentieth line to a tutoring activity, the twenty-first line to a school activity, etc The provisions of the respective rows can be adjusted and specified in such a way that the rows are adjusted according to the teaching content/content topics for which the server is to carry out the method.

In an analogous way, the columns of the matrix A determine certain teaching content within certain activities of the rows. For example, the first column determines/concerns the subject "Overhead kick", the second column the subject "Receiving the ball", the third column the subject "Inside shot", the tenth column the subject "Drawing round shapes", the thirtieth column the subject "Algebra" . Entries that determine/concern teaching content for an activity for which this teaching content is not considered meaningful are left blank or not filled. This is the case here, for example, for the entry a _11.3 .

4B and 4C show exemplarily that the dimension of the matrix A is not fixed. 4B shows a one-dimensional matrix (i.e. a vector that defines/concerns the football activity and in which each entry defines/concerns a teaching content within the football activity). 4C shows the matrix as any multi-dimensional matrix, by means of which activity and/or teaching content can be specified or supplemented in more detail. Likewise, the row length, column length, etc. of matrix A can be adapted to the respective (teaching/learning) situation. For example, the matrix can only have one row and one column, and thus represent a scalar which, for example, only characterizes or determines the activity soccer.

5 shows a schematic flow chart of the method executed by the server 2 . The server 2 implements an assignment method for data records in order to enable an individual and high-quality appraisal and/or evaluation of the teaching/learning content that has been carried out, which is recorded in a video, for example.

In the method step/step 501, the server 2 receives an instruction data record from a (second) teacher, stores the instruction data record in the database 5 and sends the instruction data record (after a corresponding request) to at least one first learner in the learning pool 7. A learner 7a then creates one Execution data record, which shows, for example, the learner 7a in the execution of the teaching content.

In step 502, the server 2 receives the execution record from the (first) learner 7a and stores the execution record in the database 5. In step 503, the server assigns the execution record to an entry, which is then added to a list comprising several entries. In method step 504, the server also checks whether the execution data record meets certain technical requirements, for example does not exceed a maximum duration of a video and/or a maximum size of the data record. Furthermore, it is checked whether a specified format, in particular a landscape format or portrait format, has been maintained. If the server determines that one or more of these requirements have not been met, the server can request a retransmission of the respective data record. In the flowchart, this is represented by “no” in method step 504, which means that method step 502 of receiving the execution data record is carried out again after it has been retransmitted. If the prerequisites are met (“yes” in method step 504), the server continues with method step 505.

In method step 505, the server provides the teaching pool 6 or specific teachers with one or more lists for selection. In an advantageous embodiment, a specific or individual list is created for each teacher. Such an individualized list can be characterized in that the server arranges the entries in the list to which the execution data records are assigned, depending on the respective teacher, using the entity data identifier and/or the content data identifier of each execution data record, and/or entries from the list removed. For example, the list can be arranged in such a way that the entries of execution data records sent to the server earlier and/or entries for execution data records from teachers (identified by the entity data identifier), which have already been evaluated more often by the respective teacher, appear higher in the list. The server also removes an entry from the list, at least temporarily, as soon as a teacher has selected an entry and the associated execution data record has been sent to this teacher. After a teacher 6a of the teaching pool has selected an entry, the server sends the execution data records assigned to this entry to the teacher.

The teacher creates a feedback data record, which is received by the server in step 506 and is stored by the server 2 in the database 5 . Depending on specifications, for example regarding the entity data identifier (and thus specifications for the teacher who created the feedback data record) or random variables, for example, the server determines in method step 507 whether the feedback data record is to be checked. If a check is to be carried out (“yes” in method step 507), the server sends the feedback data record to a different teacher than the one from whom the server received the feedback data record for checking (method step 508). The feedback data record can be approved or rejected by the second teacher. In method step 506, the second teacher sends back the feedback data record for receipt by the server. The server receives this and determines whether it was approved or rejected. If the server determines in method step 507 that no control is necessary, the server carries out method step 508 .

Through the implementation described, for example, inexperienced teachers can be checked by experienced teachers as control trainers, who can also classify the more inexperienced teachers as suitable/unsuitable. Furthermore, random checks can also be carried out for the feedback data records. In a further embodiment, the teachers can be listed in an experience list based on their entity data identifier, which, for example wisely names the most experienced teachers first. In step 508, the server sends the (released) feedback data record to the learner from whom server 2 received the execution data record and/or to one or more other learners in learning pool 7, for whom the learner released the feedback data record after receiving the feedback data record .

Overall, the server thus provides a platform that assigns and enables the prioritization of teachers in a user-specific manner for giving feedback on statements by learners. In particular, the history of giving feedback can be taken into account. In addition or as an alternative, adapted metrics can be used, for example, to recognize patterns when teachers give feedback (e.g. that a teacher often evaluates superficially and not user-specifically). Such teachers can be excluded via the assignment according to the invention insofar as they are not used to give feedback to specific learners. Furthermore, after receiving the feedback data record, a learner can evaluate whether he is satisfied with the way in which the teacher created the feedback data record. For example, the server averages the ratings received from all students to determine a teacher's rating.

The 6A-6C show an example visualization of a guidance data set 608a ( 6A ), an execution record 609b ( 6B ) and a feedback data record 610c ( 6C ) stored in the database 5 of the server. In particular, the 6A-6C , how the server makes the respective data record visualizeable by using the entity data identifier. In one possible embodiment, with the help of the respective content data identifier in the respective data set, it can be specified which activity is shown by the data set: For example, by the matrix element a ₂₃ , which is assigned to the teaching content "inside shot" of the activity "soccer" (cf 4A ).
In an advantageous embodiment, the feedback data set (as in 6C schematically illustrated) the execution record (as in the 6B schematically visualized), the feedback data set being supplemented by an overlay data set 605a and 605b. The overlay data set can include overlay video data and/or overlay image data 650a and 650b and/or overlay audio data. For example, overlay audio data can result from a voice recording of the teacher providing feedback. Furthermore, marking, for example by stars, lines 605b, squares 605a, can be included through the overlay image data. In addition, a video from a teacher and/or learner can be integrated into the feedback data record by means of the overlay video data. For example, the video can be video excerpts from an instruction data set. Furthermore, the overlay video data can be processed further by means of, for example, zooming, slowing down, time-lapse, stopping and/or by incorporating further image files and audio files.

shows as an example 6D this in a schematic visualization of a feedback data record, which was supplemented or edited by the processor 3 of the server 2 and was stored in the database 5 . For example, the visualization blocks D, D1-D3 show visualizations of a video file and/or image file and/or audio file of the execution data set or the overlay data set. The schematic visualization block A also shows an automatically generated address to the learner 607b, for example that the learner hereby receives feedback from the teacher 606c regarding a teaching content, which is identified by the content data identifier (here a ₂₃ , ie inside shot in soccer). The server creates and/or processes the feedback data record in such a way that the server includes text elements in the feedback data record specifically for the activity/teaching content designated by the content data identifier, which correspond to criteria evaluated by the teacher (e.g. position of the supporting leg and the free leg, position of the free foot etc.) included in the feedback dataset (schematic visualization block B). The criteria can be predefined blocks of text chosen by the server depending on the content data identifier and added to the feedback data set.
