And for the step of S100 classroom teaching recording, classroom teaching processes are recorded by using classroom teaching recording equipment to form original recorded courses, and the original recorded courses are stored to a recording and broadcasting server in a data stream mode.
Before a teacher 1 (or a platform administrator) starts teaching, a terminal device 10 is started, a teaching platform first generates a recorded course ID, and in the course of teaching and course recording, at least one of multimedia teaching devices such as an intelligent electronic whiteboard 301, a screen operation motion capture program of the terminal device 10, a camera 302, a microphone 303, and the like, of a classroom teaching recording device 30 enters a working state, and can record a classroom teaching process, and the formed recorded course is stored in a data stream manner. Preferably, the data stream is segmented in a fixed format and stored in a data stream segment manner. The recording server 40 may generate a digital time stamp.
In the course of giving lessons, the teacher 1 can also insert cloud or local courseware such as PPT, Word, Excel, jpg, Audio, Flash and the like at any time through the terminal device 10. The courseware is mainly provided by an internet teaching platform, a teacher can select in advance, and the teacher or a school where the teacher is located makes an agreement with the owner or the provider of the courseware in an offer form during selection. These courseware can be updated and new and old courseware identified by different version numbers.
In the course recording process, the actions on the intelligent electronic whiteboard 301 are transmitted and stored in a mode of "action data stream + timestamp", the voice in the course of teaching and interaction is transmitted and stored in a mode of "voice data stream + timestamp", the operation actions of courseware related to the terminal device 10, such as PPT document, are transmitted and stored in a mode of "courseware operation data stream + timestamp", and the acquired video data is transmitted and stored in a mode of "video data stream + timestamp". The various types of data streams are stored separately.
All the recorded data streams and the recorded course IDs in the whole teaching process are bound to realize the identification of the corresponding recorded courses. These recordings may be selectively saved, added or subtracted as desired, a typical case being voice data, video data, and courseware such as PPT document presentation data. The various data obtained by recording can be firstly stored in a local database, then the database is uploaded to a recording and broadcasting server through a network, and can also be directly stored in the recording and broadcasting server.
In the teaching process of schools, teachers mainly take target items such as teaching outlines, scholarly schedules, examination points and the like as teaching guides, take class groups, teaching and research groups and teaching plans, course arrangement plans and lesson preparation plans of the teachers as mainlines, and pay attention to teaching outline requirements, examination points, teaching plans and staged teaching contents, so that teaching of different schools and different teachers has the advantages of synchronization and mutual reference. Therefore, when a classroom is recorded, the attribute information of the formed recorded lesson generally includes a teacher, a teaching outline, stage teaching contents, and the like.
Based on the characteristics, the invention preferably establishes an association relation data table of a plurality of recorded courses relating to the same theme and an association relation data table between the recorded courses and students listening to the corresponding classroom teaching process according to the teaching themes related to the classroom during recording the courses based on the determined teaching themes such as the teaching outline, the teaching plan, the stage content and the like, so that the recorded courses can be divided into fixed recorded courses and recommended recorded courses in the learning review stage, and the association relation data tables and the recorded courses are stored to the recording and broadcasting server together. The association between the recorded courses and the association with the student can be confirmed by the course ID together with the association data table. The association relation data table may be a spreadsheet stored in an XML format.
S200, recording course updating, namely replacing old courseware in the original recorded course with new courseware, updating the recorded course and forming an updated recorded course. After the classroom teaching is completed, that is, after the recorded lessons have been completed, when the teacher or manager finds that the courseware used has a new version, if the new version is helpful for the students to better understand the teaching contents, a courseware update request can be submitted, and the recorded lessons update step is started.
As shown in fig. 3, the step of S200 recording course update includes: an S201 courseware updating step, an S202 coordinate confirming step, an S203 fragmentation processing step and an S204 replacement updating step.
S201 courseware updating step, which is used for updating the existing courseware and establishing the corresponding relation between the new courseware and the old courseware. For example, for the PPT lecture, the corresponding relation between the new page and the old page is established. Of course, the courseware is not limited to PPT, and can also be in the forms of Word, Excel, jpg, Audio, Flash and the like, or video content and the like.
And S202, a coordinate confirmation step, namely, according to the corresponding relation between the new courseware and the old courseware and the time coordinate information of the old courseware in the original recorded course, such as 'courseware operation data stream + timestamp' data, and the segmentation mode of data stream segments, such as the data information of the segmentation time and/or size of the segments, or fragmented segmentation data. And searching the using time of the courseware and courseware content displayed at the corresponding time from the originally recorded course data related to the data flow of courseware operation, thereby confirming the time and the replacement information on the content or becoming the time coordinate information.
And S203, a fragment processing step, namely, dividing the new courseware according to the fragmentation dividing mode of the old courseware, and adding corresponding time coordinate information including timestamp information and the like, so that the new courseware can quickly and equivalently cover the old courseware, and the new courseware can cover the position of the old courseware in the original recorded course in situ.
S204, a replacing and updating step, which is used for replacing and updating the old courseware based on time by using the new courseware according to the time coordinate information, so that the old courseware data in the original recorded course is replaced by the new courseware data on the original time coordinate, namely the display time and the sequence of courseware contents in the recorded course are not changed, but the display contents are changed.
For the step of recommending the recorded courses in the step S300, the student uses the client to connect with the recording and broadcasting server through the Internet, and after submitting the recorded course search request, a search result list containing fixed recorded courses and at least one recommended recorded course with the same theme is generated according to the attribute information and the search request of the student, wherein the fixed recorded courses and the recommended recorded courses are updated recorded courses.
After the classroom recording is finished, the client is connected with the recording and broadcasting server through the Internet, and after a student submits a recorded course search request, a search result list with fixed recorded courses and at least one recommended recorded course with the same theme is generated according to the association relationship between the recorded course generated in the course recording stage and the student and by combining attribute information of the student and the search request.
The method of the invention enriches and promotes school education further by means of attribute matching on the basis of meeting school education, is helpful to solve the problem that teachers are not matched with students, and simultaneously avoids school education from becoming a free trade market.
Specifically, the course recommendation process for recording courses is determined by performing matching calculation according to the attribute information of the student and the attribute information of the recorded courses on the basis of the association relation data table. The attribute information of the student may include: which area, which school, which grade, which class, the name of the own teacher, which stage in the teaching plan, gender, age, historical performance, personality, learning preferences, etc. Whether the student or the recorded course exists, each category in the attribute information has the authority coefficient of the student, and the matching degree of the student and the recorded course is calculated according to the authority coefficient of each category. For the fixed recording course, the fixed recording course information can be determined according to the searching course ID submitted by the student and the class information of the attribute information of the student.
The recommended course recommending method comprises two steps of firstly matching attribute information of a fixed recorded course with attribute information of other recorded courses to obtain candidate recommended information with the same theme as that of the current fixed recorded course, and then further performing matching calculation according to the attribute information of students, such as the learning scores and hobbies of the students to obtain a recommended course list suitable for the students. The recommendations can be based on the division information of teacher types and student types in advance, so that students can obtain the most suitable type, teaching mode or teaching speed to match themselves.
And for the step of S400 recorded course learning, the student learns the fixed recorded course and the recommended recorded course in sequence.
The step of learning by recording lessons in S400 specifically includes a step of fixed learning in S401, a step of selecting expansion in S402, a step of determining permission in S403, a step of confirming permission in S404, a step of recommending expansion in S405, a step of analyzing evaluation in S406, a step of sharing classification in S407, and a step of classifying teachers in S408.
As shown in fig. 4, the specific steps of the lesson learning step are recorded.
S401, a fixed learning step, which is used for the students to learn the fixed recording course. For students, the learning authority is different between the fixed recording course and the recommended recording course. For the fixed recording course, the students can directly review the learning without obtaining additional permission. Before the subsequent steps are carried out, the student must complete the study of the fixed recording course firstly, and the system does not carry out the subsequent steps until the system obtains the study data of the student completing the fixed recording course.
S402, an expansion selection step, which is used for enabling a student user to select at least one recommended recording course after the student completes the fixed learning and prepare for the expansion learning. For the recommended recorded course, after obtaining the permission, the student may conduct extended learning for the recommended recorded course obtained with the permission. And the recommended recording course is a recording course which is obtained by searching for the same teaching subject or the same teaching chapter taught by other teachers after matching according to the attribute information of the fixed recording course.
And S403 permission judging step, namely, according to the attribute information of the student and the attribute information query and comparison of the recorded course, confirming whether the extended recorded course to be learned has been permitted historically, confirming whether permission is obtained, and only if permission is obtained, learning can be carried out. As mentioned above, for the fixed recording course, the student can directly go through review learning without obtaining extra permission; for the recommended recorded course, after obtaining the permission, the student can perform extended learning for the recommended recorded course obtained with the permission, and therefore, it is first determined whether the permission has been obtained, and for the recommended recorded course not obtained with the permission, permission submission and confirmation are required.
S404 permission confirmation step, the learning request of the recommended recording course is sent to the third party by the recording and broadcasting server to confirm whether permission is allowed, and the permission is confirmed to be permission data obtained by paying according to the price of the recording course. In a preferred example, the license is a license obtained by paying a fee based on a price of the recorded course. That is, when the student selects the recommended course for learning, the student pays the course, and only after the payment is completed, the student can perform further learning. With respect to the generation of the course price, it is performed by S500 the course price generating step.
S405, expanding a recommending step, recommending the recommended recorded course selected by the student to a teacher of a class or a classroom where the student is located after the student obtains permission to download and completes the study of the recommended recorded course, and enabling the teacher to obtain the same operation authority as the student.
In one example, after the students finish the extended learning, the number of people and the number of on-demand programs can reach certain threshold values according to the recorded courses and the evaluation information of the learning, and the courses with the high evaluation degree reaching the threshold values are provided for the teacher of the current students, so that the teacher can freely learn and reference the recorded courses, and has an opportunity to discover and improve the service capability, and the teacher can know what teaching style the students of the class like.
And S406, an evaluation analysis step, namely analyzing the attribute information of the student selecting the recommended recorded course and the evaluation information of the selected recommended recorded course, determining the type of the student suitable for the recommended recorded course, and marking the attribute information of the recorded course. After the student finishes the learning of the course, particularly after the learning of the recommended course, the evaluation is carried out according to the condition of the student, so that the preference degree of the student for the course can be judged.
In one example, the recorded courses are classified by comprehensively analyzing attribute information of students who select recommended recorded courses and evaluation information of the selected recommended recorded courses and determining a type of the students to which a certain class or a certain recorded course is suitable in combination with the attribute information of the students. Furthermore, the classification condition of recommended recorded courses selected by students in a class or a classroom is sent to teachers in the class or the classroom, so that the teachers can conveniently know the personnel condition of the class and develop targeted teaching.
And S407, a classification sharing step, which is used for sending the classification condition of the recommended recorded course selected by the student of the class or the classroom to the teacher of the class or the classroom, so that the teacher can conveniently know the overall preference condition of the student of the class or the classroom, and the development of targeted classification teaching is facilitated.
For example, according to behavior data analysis of recommended recorded courses selected by students, mainly the number and evaluation degree data of the selected recorded courses, the dispersion and polymerization degree of students in a certain class for different types of recorded courses can be seen, that is, students in a certain class prefer a teacher in a certain type, and the teacher is not suitable in the current class, so that reference data can be provided for school managers, teacher resources can be reasonably configured, and the configuration is based on effective data analysis and does not completely depend on subjective judgment of the managers.
And S408, a teacher grading step, namely grading the recorded courses according to the number of the selected persons of the recorded courses and the evaluation information, grading the teachers of the recorded courses on the basis of the grading, and endowing the teachers with corresponding grades according to the IDs of the teachers, such as a common grade, a grade excellent, a school grade excellent, a district grade excellent, a city grade excellent, a provincial grade excellent, a national excellent and the like. Specifically, the teacher is assigned a corresponding grade according to the ID, such as general grade, annual grade, school grade, district grade, city grade, provincial grade, and national grade. After the teacher obtains the corresponding level, the teacher can be selected by students of different ranges, such as a teacher of a common level, the recorded course of the teacher can be selected by students of the current grade of the school, and a teacher of a superior level can be selected by students of the current grade of each school in the city.
For the S500 course price generating step, price data for the recorded course is generated. The recorded course price is dynamically adjusted on the basis of the basic price, stepped addition is carried out according to the number of people who buy a certain recorded course, and the more the number of people is selected, the higher the purchase price of the later selected people is. Meanwhile, if other students in front of a certain student do not finish learning or quit, the purchase prices of students behind the other students are dynamically adjusted automatically according to the distribution situation of the stepped prices. The base price is a prior agreement, such as in the form of an offer, between a course owner, such as a teacher, or a learning and teaching platform.
In one example, the price of the recorded course is determined according to two factors of the number of persons who order the course and the evaluation, the price of the course is increased in a step shape when the number of persons who order the course is more, the number of persons who order the course is sorted in sequence, if the previous persons do not complete the learning and are disqualified, the later persons automatically obtain the price enjoyed by the previous persons, such as the price of the first 1-100 persons, the price of the 101-. In this way, it is possible to prevent excessive students from gathering in individual excellent recorded courses by means of price.
In one example, for a student paying for a lesson, if the student insists on learning to complete, a discount right is obtained according to the acquired achievement when the student chooses the lesson next time. This discounted weight is used as a coefficient for the calculation when later calculating the benefit of the recorded lesson.
As shown in fig. 5, the step of S500 course price generation includes a step of S501 basic price engagement, a step of S502 calculating the number of purchasers, a step of S503 dynamic price adjustment, and a step of S504 generated price adjustment.
S501, basic price appointment step, which is used for obtaining basic price data which are achieved by the owner of the recorded course and the teaching platform according to the offer. For the owner of the recorded lesson, the discount coefficient can be set as required on the basis of the contracted basic price. For example, according to the historical data, a discount coefficient, for example, 0.8-1.2, can be set for the promotion requirement, and the price can be adjusted according to the requirement.
S502, a step of calculating the number of purchasing persons, which is used for counting the number of persons purchasing the recorded courses, dividing the number into different sorting intervals according to the purchasing sequence, and similarly, the prices of the recorded courses in the different sorting intervals are different. In one example, as an option, an entry submitted within a certain time is a pricing region beyond which a pricing strategy is determined by time and number of people.
S503, a dynamic price adjusting step, which is used for dynamically adjusting the price according to different sorting intervals, and carrying out ladder-type pricing according to the increase of the number of purchasing people, wherein the more the number of purchasing people is, the higher the purchasing price of the later selected person is. And when the number of the students reaches the upper limit, the students are stopped from being allowed to enter the learning.
And setting a maximum student threshold value according to the level and the number of students at the level. Different numbers and price coefficients can be obtained according to the teacher grade, such as district grade excellence, city grade excellence, province grade excellence and national excellence.
And S504, a price adjusting step is generated, and the price adjusting step is used for dynamically adjusting the purchase prices of other students with changed sequencing according to the sequencing change and the ladder-type price distribution condition automatically when the students in a certain sequencing interval do not finish learning or quit. When the people who reported the study before exited, the system redetermined the whole rank order, carried out dynamic price adjustment, that is to say unified reduction price.
For the payment mode, when a student tries to select a recommended recorded course for learning according to the recommendation of the teaching platform, the teaching platform sends the information of requesting payment to a third-party user through the recording and broadcasting server 40, and the third-party user may be a parent of the student or an account set by the parent of the student.
In one example, the account set by the third party user may include conditional permissions, i.e., permission to download if the number of people who agree to download or purchase a particular instructional material reaches a certain number, and/or if the ratio of the number of people reaches a certain ratio, for example, over a period of time, or at a certain point in time. For the recorded courses needing payment, pre-payment can be submitted, and after the conditions meet the requirements and the license takes effect, actual payment operation occurs again. After payment is completed, the student can proceed with learning.
For the step of S600 profit calculation and distribution, profits of the recorded lessons are calculated according to the purchase price, the corresponding number of purchasers and the use condition, and profit distribution is performed according to the preset offer ratio of the owners of the recorded lessons to the owners of the used courseware.
For the allocation of benefits gained for the courseware, the new courseware and the old courseware continue to allocate the allocation of benefits gained according to a pre-offer rate as new courseware is iteratively updated on the basis of the old courseware.
The price paid is a prepaid price, and the actual consumption price is comprehensively calculated according to factors such as discount coefficients, preferential conditions, learning time of the students, the quitting conditions of the students and the like, wherein the discount coefficients and the preferential conditions are acquired by the students, and the learning time is not an encouragement period, so that the actual consumption price is generated. Since the purchase price is a prepaid price, the actual price is considered according to various practical factors. For example, if the student has previously learned the discounted rights, the student uses such discounted rights to recalculate the actual price when the current recorded course learning is completed.
In order to encourage the updating and promotion of published courseware, for courseware with the same theme, continuous upgrading and promotion can be carried out later, the later promotion and upgrading can not be the same person, when the later new courseware is used for replacing the new courseware in the recording course, the benefits brought by the recording course using the new courseware and the old courseware are distributed according to the convention of advance offers.
According to the method, firstly, a teacher in a school forms classroom teaching into a recorded classroom and uploads the recorded classroom to an Internet teaching platform, so that the problem of the retrospective learning of students in classes or classes in charge of the teacher can be solved; secondly, after the teaching resources are used, after the students finish the course review of the teachers in the class or classroom, namely the fixed recorded course is reviewed, the students also have the opportunity to learn or experience different teaching modes of other teachers, namely the recommended recorded course learning, so that the problem of sharing the teaching resources of school education is solved; thirdly, some knowledge service platforms in the prior art are basically in a pure selection and purchase relationship and lack of scene application depending on school education, after basic fixed learning is completed, extended learning can be selected in a payment mode, and selected resources enable teachers of students to obtain free learning opportunities, so that multi-party sharing of teaching data is realized; fourthly, through the recommendation and selection, the behavior data of the students are analyzed, scientific classification of teachers, recorded courses and student types can be achieved, and reasonable configuration of teaching resources can be carried out based on the classification.
