AI Technical Summary

Technical Problem

Existing tutoring video generation technology fails to design content based on students' individual learning situations, resulting in an inability to provide customized explanations for the different reasons for each student's mistakes, thus limiting the improvement in learning efficiency.

Method used

By identifying the key points, difficulties, and error reasons of the target test questions, a personalized video script is generated, including a basic script and error reason branch scripts. The video files are then integrated and embedded with the identifiers of the error reason branch video segments and the error reason mapping relationship, thus realizing personalized tutoring videos.

Benefits of technology

The generated supplementary learning videos can provide customized explanations based on the specific reasons for students' mistakes, fill in knowledge gaps, and improve learning efficiency.

Abstract

This application discloses a method and device for generating supplementary learning videos based on the key points, difficulties, and error causes of test questions, relating to the field of smart education technology. This application determines a list of key points, difficulties, and error causes for a target test question. Based on the target test question, the list of key points, difficulties, and error causes, it generates personalized video scripts, including a basic script explaining each key point and difficulty of the target test question, and error cause branch scripts inserted into the basic script related to each key point and difficulty. Basic explanation video segments corresponding to the basic scripts and error cause branch video segments corresponding to each error cause branch script are generated respectively. These are integrated to obtain a video file. The mapping relationship between the identifiers of the error cause branch video segments and the error causes is embedded in the video file, resulting in personalized supplementary learning videos for the target test question. This provides targeted explanations for different error causes, enabling students to fill their knowledge gaps and improve supplementary learning efficiency after watching.
