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

这项研究旨在将涵盖从三年级到九年级的广泛主题的真实科学课程录制下来。这些课程由日本不同地区的有经验的中小学教师授课，他们被选为本研究的模范教师。在本研究期间，共录制了89节科学课的视频并进行了分析。每一位老师都给我们提供了教案。本研究还旨在阐明每节录像课的哪些教学方面是优秀的。我们使用了不同的经验丰富的教师群体来收集这类信息，他们观看了每一节课的视频，并使用分类系统和问卷对其进行了评价。六名评价员分别观看了一节录像课程，并在观看视频过程中发现一些好的方面时，每一刻都在卡片上写下他们的评价评论和课程的时间代码。评价员还在问卷中写下了他们的意见，最后提出了更多的一般性意见。我们还打算将这些信息用于职前和在职教师培训。我们开发了一个多媒体学习系统，它由教学视频、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观看各种主题的实际科学课，了解每个主题是如何教授的，并讨论哪些方面的教学可以做得更好。我们还报告了TIMSS 1999科学课研究报告中2006年公开发布的20节外国科学课的特点。

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.
