Lesson Video Study on Excellence in Elementary and Secondary School Science Teaching and its Application to Teacher Education

本研究的目的是录像实际的科学课程，涵盖了广泛的主题，从3年级到9年级。这些课程是由日本各地区中小学经验丰富的教师讲授的，他们被选为本研究的模范教师。本研究以89节科学课为研究对象，进行录像分析。本研究的目的，也在于厘清每一节录影课的教学内容，究竟哪些是最佳的。我们使用不同的经验丰富的教师组来收集这类信息，他们观看并评价每节课的视频，使用分类系统和问卷调查。6名评价者分别观看了一节录像课，并在观看录像过程中发现好的方面时，在卡片上写下他们的评价意见和课程的时间代码。最后，评估者将他们的意见写在一份问卷中，以获得更多的一般性意见。我们也希望将这些信息用于职前和在职教师培训的目的。我们开发了一个多媒体学习系统，它由课程视频、教案、优秀方面的评论和教师的反思组成。教育机构的教师和未来的教师可以使用该系统来观看各种主题的实际科学课程，了解每个主题是如何教授的，并讨论哪些方面的教学可以是优秀的。我们还报告了2006年公开发布的20个外国科学课程的特点，从TIMSS 1999年科学课程研究。

This study aimed to videotape actual science lessons covering a wide range of topics from grade 3 to grade 9. These lessons were taught by experienced teachers of elementary and secondary schools in various areas in Japan who were chosen as the model teachers for this study. Total of 89 science lessons were videotaped and analyzed during the period of this study. Every teacher provided us the lesson plan.This study also aimed to clarify what teaching aspects in each of videotaped lessons are excellent. We used different group of experienced teachers to collect this kind of information who watched and evaluated each lesson videos by using a category system and questionnaire. Six evaluators individually watched a videotaped lesson, and wrote their comments of evaluation and the time code of the lesson in a card in every moment when they identified something good aspects during watching the video. Evaluators also wrote their comments in a questionnaire for more general comments in the end.We also aimed to use this information for the purpose of pre-service and in-service teacher training. We developed a multi-media learning system which composes of lesson videos, lesson plans, comments for excellent aspects, and teachers' reflection. Teachers and prospective teachers in educational institutions can use this system to watch actual science lessons of a variety of topics and learn how each topic is taught and discuss what aspects of teaching can be excellent.We have also reported the characteristics of twenty foreign science lessons which have publicly released in 2006 from the TIMSS 1999 Science Lesson Study.
