Development and Practice of a TA Action Recording System for Programming Exercises

Abstract

In this study, we propose a TA (Teaching Assistant) action recording system to reflect learning support behavior using first-person angle video. In order to support learners flexibly, TA is required to think and act independently. It is expected to arouse awareness to develop independence by reflecting the learning support behavior. However, it can be a burden to check the entire video that is recorded during exercises. To solve this problem, we have developed the system that estimates actions from the data of the accelerometer worn by TA and presents them as clues while reflecting the learning support behavior. From the results of experiments in which TAs reflected using the system, it was possible to identify the learning support behavior of TAs with an accelerometer. By presenting the clues, the reflection time of the video was shortened for all TAs. It was suggested that TA could efficiently reflect the learning support behavior by using the system.
