Embodiment

[0015] Example: like figure 1 The shown subtitle-based automatic learning effect test method for video interactive learning includes three parts: a learning control unit, a subtitle test question generation unit and a feedback control unit. Specifically include the following steps:

[0016] (1) Play learning videos;

[0017] (2) The teacher sets parameters through the learning control unit: set the time period of the video test, the time period of video interception, the initial time t1, and the end time t2;

[0018] (3) Use a random function to select n subtitles from the subtitle files corresponding to the video in the time period t1 to t2 as the test answer, and select m subtitles in the subtitle files corresponding to the video in other time periods as the confusing answer to form a test question; The subtitle content of each test question is randomly selected, and the same content will not appear. The form of the test question can be multiple choice questions, fill-in...

Abstract

The invention discloses an automatic video learning effect testing method based on subtitles. The method comprises the steps of (1) playing a learning video; (2) setting parameters with a learning control unit; (3) selecting n subtitles from corresponding subtitle files in the video in the time period between t1 and t2 by means of a random function to serve as test answers, and selecting m subtitles from corresponding subtitle files in the video in other time periods to serve as confusion answers to form test questions; (4) conducting test through a subtitle test question generating unit, wherein video playing is suspended when the video is played to the t2 moment, and the test questions are displayed on the screen for a learner to answer; (5) processing the test result through a feedback control unit, continuing to conduct video learning of the next stage and repeating the steps (3) to (5) if the learner finishes the test questions, and processing the test result with a failure processing program by regarding the result as a failure if the learner does not finish the test questions, replaying the video sections from t1 moment to t2 moment under the default setting of the failure processing program and repeating the steps (3) to (5). According to the method, questions are automatically generated according to the subtitles appearing in the video for the learner to answer, and it shows that the learning effect meets the requirements if the answers are correct.

Description

technical field [0001] The invention relates to the field of foreign language teaching, in particular to an automatic test method for video learning effects based on subtitle automatic questioning. Background technique [0002] With the popularity of the Internet, we can easily obtain a wealth of English teaching materials from the Internet, such as Hollywood movies, American dramas, celebrity speeches and other video materials. However, we often overlook the use of Chinese and English subtitles for these video materials. Subtitles in English videos can help us better understand the content of the dialogue of the characters in the video and deepen the study of the video material. However, there is currently no method that can reasonably utilize these resources to assist foreign language learning. Contents of the invention [0003] Purpose of the invention: In order to deepen learners' understanding of video materials and effectively utilize idle subtitle resources, the p...
