The purpose of this study is to analyze the TPACK differences between pre-service and in-service teachers in China, and determine demographic influence variables on the differences between them. The participants of this study were 567 teachers, including 335 pre-service teachers and 232 in-service teachers from Ningxia, China. The results are as follows: First, The in-service teachers in the seven areas of TPACK scored higher than those of pre-service teachers; Second, The comparison of the average difference between teacher division and gender shows that the two factors have an interactive effect on TK. This study is meaningful because it compared the TPACK differences between pre-service and in-service teachers, and found out the effect of gender interaction on the differences in China; It provides practical suggestions for improving the TPACK ability of Chinese teachers. Finally, the discussion was conducted based on the results, and a follow-up study was suggested.

This study is about in-service training structure combined digital competence and pedagogical knowledge in order to improve digital tools skill of a teacher in the school. Meanwhile domestic teacher training has been revealed low-level of applying into a teaching in the k12 school. Thus this study proposed teacher training system with focus on TPK sub-categories of TPACK. The core contents of TPK is to select appropriate digital tool for its teaching & learning. Additionally it is to select elements of teaching & learning associated with an attribute of digital tool. And this study presented modularize of 3 step such as teaching objective, teaching contents, assessment. Also we proposed that this training system should be operated with problem solving method which trainee itself compose TPK elements. And we committed quality investigation about picking up Strategies of TPK elements and the teacher training frame. The Participants concluded having a validity about TPK strategies, teacher training framework.

The purpose of this study is to compare and analyze the perceptions of TPACK for mathematics teachers who practice the technology-using lessons. In addition, by looking at the part where the perception is expressed in the actual class and the part where the difference of recognition can be revealed, it is possible to provide the direction to teachers who want to practice the technology-using lessons in the future. To do this, two mathematics teachers were selected using purposeful sampling. And we conducted research study and interview in order to analyze the characteristics of the teacher's general background and TPACK recognition, and we analyzed the video, the class materials, and the interview contents for teaching practices from the perspective of TPACK. As a result, the two mathematics teachers practicing the technology-using lessons were connected with the actual class situation focusing on the sub-knowledges of TPACK recognizes as having a lot of them. In addition, technology-based lessons were able to confirm that the functional capabilities of technology alone were not sufficient conditions to lead effective instruction. Finally, teaching method using technology has been confirmed that experience-based field practice can be more important than simply knowing mathematics content, technology, teaching method. Based on the results of this study, it is possible not only to provide methodological guidance to teachers who practice the technology-based instruction, but also to suggest the direction of TPACK research or the development of teacher training program in the future.
