Abstract EN
Teaching reflection based on videos is the main method in teacher education and professional development.
However, it takes a long time to analyse videos, and teachers are easy to fall into the state of information overload.
With the development of “AI + education,” automatic recognition of teacher behavior to support teaching reflection has become an important research topic.
In this paper, taking online open classroom teaching video as the data source, we collected and constructed a teacher behavior dataset.
Using this dataset, we explored the behavior recognition methods based on RGB video and skeleton information, and the information fusion between them is carried out to improve the recognition accuracy.
The experimental results show that the fusion of RGB information and skeleton information can improve the recognition accuracy, and the early-fusion effect is better than the late-fusion effect.
This study helps to solve the problems of time-consumption and information overload in teaching reflection and then helps teachers to optimize the teaching strategies and improve the teaching efficiency.
