In the prior art, for the learning effect, whether it is the classroom learning effect or the after-school review effect, it is mainly tested by means of homework, testing, etc., for the recorded classroom teaching, the curriculum review and the learning consolidation are in an uncontrollable free state. Most of the time it is like watching a video, there is almost no interaction, and you can't understand the effect of the student's review.

With the development of the times, the requirements of the society for higher and higher education are getting higher and higher, parents' expectations for children are getting higher and higher, and the enthusiasm of parents to participate in or supervise their children's learning is also growing, aiming at the self-discipline of students in the K12 education stage. Two major characteristics, such as not strong and mandatory content of learning content, the present invention aims to solve the problem by analyzing the existing technology and the prior art mainly focusing on the interaction and sharing of pre-class preparation, in-class learning and after-school homework. In the prior art, there are problems in curriculum review and learning to consolidate inefficiency, and a method and system for improving the efficiency and effectiveness of recording and on-demand teaching in classroom teaching, changing the traditional way of reviewing and consolidating, and truly recording the classroom The role and effect of the play out.

Summary of the invention

In view of the above new problems, the method and system for recording and on-demand of the classroom teaching of the present invention are aimed at solving the course of recording and on-demanding of the classroom teaching process after the completion of the teaching based on the computer network and multimedia, so that the course review such as recording is performed. Classroom review and study to consolidate the efficiency and effectiveness of mastery and understanding of the content of the class, such as homework, testing, etc. Among them, the curriculum review is aimed at repeating or reviewing the content and key points of the class, and mastering the knowledge that must be mastered, such as the key points of the class. The main points of the lectures are usually more than one level. In the K12 stage, there are generally two or three levels, that is, there are big points. Each big point will have small points and even smaller points. Learning to consolidate includes classroom work and/or quizzes, which is positioned to further master the knowledge that must be mastered, such as the key points of the class, or to test again.

The main inventive aspects of the invention include the following five aspects:

During the course recording process or during the recording of the classroom teaching data processing stage, according to the main points of the classroom explanation, the recording of the classroom teaching data is marked and segmented by generating a specific time stamp identification method, and the corresponding points of the classroom explanation points and the segmentation teaching data are constructed. The relational database; the classroom teaching data may be video course data, micro-course data, or combined data composed of an action stream, an audio stream, and an image stream. Particularly preferably, the "marking segmentation" of the recorded classroom teaching data of the present invention does not substantially cut or segment the recorded classroom teaching data, but is segmentedly identified by a timestamp identifier, and such marking segmentation may be Levels, not one segment only corresponds to one point of explanation. The method of timestamp identification facilitates the different levels of "segment identification data" to establish correspondence according to needs.

By marking the segmentation, in the course of the course review, according to the association database, the classroom teaching content can be displayed in steps or in stages, and only the previous content can be used to enter the later review, for example, the student needs to answer questions and answer these questions. The way of the problem may include selection method, text answer, voice answer, handwritten answer, etc. (preferably, handwriting input such as chemical formula, formula, object understanding question and voice input, which is the most efficient, the text input speed is slow, but the effect may be the most Well, you can let the students slowly think, deepen the memory), or after answering the question, by answering the question and confirming which part of the content is not well mastered, you can directly review the segmentation mark classroom data related to the relevant question. There is no need to review the comprehensive classroom content. Further, the corresponding association relation database includes relationship data corresponding to the classroom explanation key points, the segment identification data, the questions, and the test questions. Particularly preferred, the problem described in the present invention is about the content of the lecture point itself, and is not a further problem derived from the explanation of the content, unlike the subsequent test questions and tests, etc. The problem is to let students repeat the main points of the class.

Further, a third-party terminal, such as a parent terminal, is provided for remotely tutoring the student, and when the student reviews the recorded classroom, the process of reviewing the student is synchronously displayed, and the correct content and the actual answer content of the student are provided for the question that the student needs to answer. The real-time synchronization comparison shows that the parents only need to compare and compare, basically can judge whether the student answers correctly, and through the confirmation of the parent, the correct, incorrect or partially correct prompt is given to the student's answer. In this way, in the prior art, the parents are only the bystanders and the "monitor" problem, truly participate in the student's learning process, through the interaction between the parents and the students, have the opportunity to play a true tutor. Character.

Further, the voiceprint recognition function is provided when the student answers the question by audio, and the content that needs to be answered by the voice is recognized, and then converted into a text and displayed, for example, can be displayed to the parent, and the speed at which the answer is correct can be improved.

Further, in the process of reviewing the recording classroom, in the process of performing the homework or the test, the work problem and the test question are associated with the classroom teaching content, and when the wrong question or the problem occurs, the work item or the test question may be correspondingly reviewed again. The class segment will review the relevant content instead of directly answering the questions, guiding the students to fundamentally grasp the knowledge and solve the problem.

Further, when there is an error in answering the test questions, a certain number of other test questions involving the same points are pushed according to the lecture explanation points associated with the wrong test questions.

detailed description

Specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

As shown in FIG. 1-3, a schematic diagram of a composition and method flow of a recording and on-demand system for classroom teaching for online teaching in the K12 education stage according to the present invention.

The system relies on the information network teaching platform (system) of the campus network, and mainly includes a schooling system, a teacher system, and a student system. The school affairs system involves teaching management, online live broadcast, course recording (course intelligent shelves, review on-demand list, recording course file management), including the management of recording equipment based on the information network based on the campus network, such as cameras, as well as classrooms and subjects. Correlation and corresponding management of information such as curriculum, teachers and teachers. The teacher system involves course management, assignment work, and correction work. The student system involves online review on-demand, online answering assignments, online question bank evaluation, and more.

Specifically, the system includes the following modules: a teaching management module 10, an online live broadcast module 20, a course recording module 30, a course management module 40, a course review module 50, a learning consolidation module 60, and a synchronization management module 70. among them,

The teaching management module 10 includes a teaching server 101, a storage device 102, and an acquisition device 103 (including a camera device 1031 such as a gun-type network camera and a pan-tilt network camera, a recording device 1032 such as a pickup, and a motion capture device 1033 for collecting on a multimedia whiteboard and For the operation of word documents, PPT documents). Optionally, the collection and collection device 103 can be a micro-class recording device. Through the information-based teaching platform relying on the network, after the system is started, it is used for the management of network teaching, and realizes classroom tables, classrooms, teachers, grades, classes, subjects, and collection equipment (including camera devices, recording devices, motion collection devices, etc.). The association, recording and storage of classroom teaching data (including shelves, shelves, deletions, downloads, etc.). After the course recording and processing is completed, it is responsible for recording the smart placement of the course.

Online live broadcast module 20: The teacher uses a user terminal such as PC (Win/Mac)/Pad (Android/iOS)/Phone (Android/iOS) to connect to the teaching server through the campus network/Internet/2G/3G/4G/Bluetooth anytime and anywhere. 101 realizes the opening of the classroom; the student connects to the teaching server 101 through a campus network/Internet/2G/3G/4G/Bluetooth using a user terminal such as PC (Win/Mac)/Pad (Android/iOS)/Phone (Android/iOS). Joining the classroom, the collection device 103 separately collects the image data stream + time stamp, audio data stream + time stamp and action data stream + time stamp taught by the teacher, and distributes them in real time through the server to realize online live broadcast of the classroom, and the student user terminal is real-time. Obtain three kinds of data streams that are distributed, and implement online learning after re-combining locally according to timestamps. The time stamp is uniformly generated by the teaching server 101.

The user terminal includes: a processor, a network module, a control module, a display module, and an operating system; the user terminal can be configured There are various data interfaces for connecting various extension devices and accessories through a data bus; the operating system includes Windows, Android and its improvements, and iOS is a running platform on which application software can be installed and run, and implemented under the operating system. A variety of applications, services and features of the app store/platform.

The course recording module 30 is configured to process the image data stream + time stamp, the audio data stream + the time stamp, and the action data stream + time stamp obtained by the collecting device 103 into the storage device 102, where the storage device 102 It can be local storage (local disk array) or network cloud storage and any combination of them.

The processing includes segmentally identifying the collected classroom teaching data according to the time sequence of the lecture explanation points, forming segmentation marking classroom data corresponding to the classroom explanation points, and establishing a classroom explanation point and a segmentation mark. Corresponding associated database of classroom data. The corresponding associated database is stored on the storage device 102.

The segmentation identifier is implemented by the teacher or other professional staff to generate a specific time stamp for identification according to the time sequence of the lecture points. At the same time, a correspondence table between the lecture explanation points and the segment identification data will be established, so that in the subsequent review or consolidation stage, the corresponding relationship can be used, and when answering the corresponding question set, only a certain segment identification data needs to be viewed. You can review the corresponding lecture points, without having to watch all the content, improve efficiency and increase the pertinence. The problem is related to the lecture point itself. In general, the answer is the lecture point itself or its equivalent.

For example, a class teacher talked about three main points of ABC, D is a typical example, and E is a little note. These five points are all points of the class explanation. These contents are all to be mastered. The main points and precautions are to be remembered. The examples should be able to repeat the calculations. These explanations are chronological. For example, the first 1-5 minutes mainly involve A, and the 6-10 minutes mainly involve B. 10-15 minutes mainly involves C, 16-20 minutes mainly involves D, and 21-26 minutes mainly involves E. Then the classroom teaching data is divided into five sections corresponding to ABCDE, and questions about the corresponding points are set, and an association list is established. After compressing the recorded data and removing unnecessary content such as silent time and noisy time, the actual time is shortened, which greatly improves the effective classroom time. For example, the typical example time D is actually less than 3 minutes.

Further, the point includes a plurality of different hierarchical points having high and low affiliation, and according to the points of different levels involved in the recorded classroom teaching data, the segment marking classroom data may correspond to corresponding specific lower level points and their corresponding points. A high-level point, and a correspondence list is established in the corresponding association database according to a time relationship.

For example, in the above example, the B point includes three sub-points of abc, and the b sub-points also include three small points of 1, 2, and 3, then the 6-10 minutes belong to the B point, and the 6-7 minutes belong to the a sub-point. 7-9 minutes belong to the b sub-point, the 7th minute belongs to 1 small point, and 8 minutes belong to 2 small points. When reviewing the key points of B, it will include the various points of the lower layer. When reviewing the small points, only the corresponding small points are involved. By generating different timestamp identifiers, these points can be determined according to the inclusion relationship between the time stamps. The affiliation between the two, so that there is no need to substantively segment the classroom data, but to achieve different flexible multi-level associations as needed. In the above two examples, the description of the time period is only for ease of understanding, and the whole time number is used, which is merely exemplary, and is actually identified according to the specific situation.

In addition, the main points of the classroom are different, such as English, sentence patterns, grammar, words, etc., focusing on their four aspects of listening, speaking, reading and writing; language, new words, texts, dictation, etc.; Department, formula, principle, example, etc.

Further, the processing further includes compressing the collected data to remove a paused portion, a silent portion, a noise, a noise, and the like in the classroom, thereby forming effective classroom teaching data, when the specific time stamp is detected. The time before and/or after 1-5 seconds of the specific time stamp is not subjected to compression processing.

The course management module 40 is configured to further process the recorded classroom data, add questions and answers about the key points after recording each piece of data in the classroom or after the entire data, and explain the main points and questions in the classroom. A correspondence of answers is added to the corresponding associated database. These points are what students should master in class, and students can accurately understand these things. The problem mentioned is that it corresponds to the main points of the lecture, and it can be the main points of different levels. The answer is generally the corresponding lecture explanation point or its equivalent content. That is to say, this stage is to let students repeat these points, one by one, not the flexible use of this knowledge, the flexible use of this knowledge is evaluated by the following homework or test.

Further, the recorded classroom teaching data is associated with the collection device, thereby obtaining the grade and/or class of the classroom, obtaining the classroom table information through the grade and/or class information, and realizing the association with the teacher data through the class time and the subject of the class table. To intelligently generate a classroom profile for recording classroom teaching data, and to view teacher details by teacher name.

Specifically, the data for the class introduction includes:

●School, grade, class, room number

● Teacher personal information (message, introduction, syllabus, grade, class, subject, etc.), grades, classes, teachers and professors taught by teachers

● Classroom table, corresponding class table entry for grades/classes

● Classroom: information on the grade/class/floor number, acquisition equipment (including camera, recording device, motion capture device, etc.)

● Database association: teacher personal information, teacher's grade/class, subject, classroom floor, teacher time point through class table, grade/subject to achieve association

For example: 5th grade four classes Chinese class 11:00-11:45 substitute teacher: Zhang XX classroom: Mingde Building 504 hours: 45 minutes classified attribution: primary, fifth grade, language

Course review module 50: for students to use PC (Win/Mac) / Pad (Android / iOS) / Phone (Android / iOS), connect to the teaching server 101 through the campus network / Internet / 2G / 3G / 4G / Bluetooth, etc. anytime, anywhere On-demand (review) a class, through the classroom profile recording the classroom teaching data to quickly obtain at least one of the corresponding image data stream, action data stream and audio data stream, to achieve fast, smooth on-demand / review.

During the on-demand review, the student must answer questions about the key points of the classroom corresponding to each segmented classroom data after marking the classroom data for each segment or after the entire classroom teaching data. Text input, voice input or handwriting input, when voice input is used, speech recognition can be converted into text. When the student answers a question correctly, confirm that he has mastered the corresponding points of the class explanation; when the student fails to answer a question correctly, he can review the segmentation mark classroom data corresponding to the question without reviewing other already mastered Segmented classroom data.

Optionally, after each segment of the identification data, set up corresponding questions, such as the classic test questions in the class, the students must fully grasp the solution, in order to proceed to the next step, this time, the students must repeat the answer process of the test questions, confirm the correct After that, we can continue to review, so that we can solve the problems that must be mastered at each stage. This kind of review makes sense, otherwise it just rushes past and has no value.

The Learning Consolidation Module 60 is used to further consolidate the knowledge of the class learning through the homework and/or test after the course review, and to explain the test questions of each of the attendant homework or the classroom test and the corresponding classroom. Correspondingly, the correspondence between the test questions and the lecture points is added to the corresponding associated database.

When the student answers a question correctly, it is confirmed that the corresponding lecture points have been mastered. When a student fails to answer a question correctly, he or she can review the segmented marker class data corresponding to the question without having to review other segmented marker class data that has been mastered.
