| dc.description.abstract | In order to enhance teachers’ the professional development, the government actively promotes that schools and teachers should regularly hold teaching observation activities, invite peer teachers to observe the classroom as well as give feedback in the teaching observation activities. By re-examining and reflecting on their teaching content and process through the feedback from other peer teachers, teachers can generate new ideas and advance their teaching. The main purpose of this study is to develop the ＂Great Teaching Observation Platform＂（G.T.O.）. It is hoped that G.T.O. platform will help teachers solve the problems and difficulties encountered in teaching observation activities, and will better facilitate teachers in the creation and participation of teaching observation activities ; meanwhile, it will give teachers a better experience of teaching observation. After completing the system development, through the ＂questionnaire method＂, 51 formal teachers who were currently teaching at the teaching site or pre-service teachers and teachers who were about to enter the teaching career would be invited to carry out simple operation and use for the system, afterwards, they were asked to complete a preliminary evaluation of the system. This study is based on the questionnaire responses from all participant teachers to assess the teachers’ overall perceived usefulness, perceived ease of use, and reuse intention of G.T.O. platform. From the results of the data analyses, it is known that the teachers have a positive response to the perceived usefulness, perceived ease of use, and reuse intention of the G.T.O. platform. In addition, the feedback provided by the teachers is used to evaluate the perceived usefulness, perceived ease of use, and reuse intention of the scaffolds and tools provided by the G.T.O. platform. From the analysis results, the teachers also believe that the scaffolds and tools provided by the G.T.O. platform have a positive effect. It is hoped that through the results of the system evaluation and the comments or feedback given by the teachers, the system will be further improved to make the ＂Great Teaching Observation Platform＂ more meet the teachers’ needs of the teaching site, providing greater assistance for teachers and brings more benefits to the process of teaching observation activities. | en_US |
