Abstract
In recent years, bilingual education has become a critical index, and with its growth, internationalization has been significantly improved in the Republic of China (Taiwan). Therefore, countries worldwide are promoting all-English teaching, taking English as a medium of instruction and indicator of university education while moving toward an internationalized curriculum and teaching excellence. Finding the required number of bilingual teachers is also one of the keys to increasing the index. If information technology can be adopted to reduce the time and cost of bilingual teacher training, it will significantly improve the effectiveness of bilingual education promotion. However, the current traditional online training system only focuses on the delivery of one-way training content, and it cannot assist in judging the training effectiveness of the trainees. In this paper, we integrate the pose estimation technology into the online teacher training system to analyze the interactive content of the trainees during the training. We can assist in recording and interpreting the teaching demonstration process in classroom observation. We also verify the result by comparing our method’s efficiency and judgment accuracy with the traditional way. The results show that our approach is more convenient and cost-efficient.
Highlights
We proposed a method for improving the efficiency of online teacher training courses for bilingual education which depends on the technique of cyber-physical systems (CPS)
Through pose estimation and video, audio, and image analysis, the proposed methodology can be applied to classroom observation and bilingual teacher certification, assisting in recording and interpreting the teaching demonstration process
Our evaluation shows that the methods of analysis and calculation had a certain accuracy for most of the teacher training courses compared with manual judgment, and our system can provide objective information for further consideration
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Under the policy plan of promoting bilingual teaching and new southbound learning in Taiwan, the degree of internationalization of education has been correspondingly increased. This environmental factor has significantly increased the learners’ demand for second language learning. The venue will not limit exercise, and the training content can be updated in real time and at a low price This makes full use of many online multimedia resources to enhance the richness of the course, and students can decide their own learning time
