Study on Science Lessons through Lesson Videos and the Effective of Application to Teacher Education: Collaboration with the IEA/TIMSS-R Lesson Video Study

1.科学课视频分析方法的发展在这种方法中，课程评价员观看科学课视频，写下他/她的课程评价评论。在此基础上，对视频课程的评价进行了分类，并建立了科学课程评价框架。然后，从多个评估者收集的评论显示了评估者之间的共性和差异，2.日本科学课录像的分析随机抽取IEA/TIMSS中的95节科学课进行录像，日本理科教师根据我们的教学录像分析方法，对1999年至2000年日本全国的R课录像研究进行了分析。在科学教师教育中，既有有效的教学策略，也有无效的教学策略，其中8节课被整理成课程录像和其他印刷材料，4节课被翻译成英语，并被带到美国、澳大利亚、澳大利亚、美国和美国。和捷克共和国，收集这些国家的理科教师对日语课的评价数据。美国、澳大利亚、荷兰和捷克共和国的科学课视频样本被翻译成日语，并由日本专家科学教师根据与日语课程完全相同的方法进行分析。美国科学课在许多评价类别中的评价相对高于其他样本，4.研究材料在科学教师教育中的应用教育中心和大学的教师教育一直表现出很高的效率和满意度。

1.Development of Science Lesson Video Analysis MethodIn this method, lesson evaluator watches a science lesson video, writing his/her lesson evaluation comments. After this work, all comments on the video lesson are classified into categories based on a developed "Science Lesson Evaluation Framework". Then, collected comments from multiple evaluators show the commonality and difference between evaluators, which can be used to extend the discussion on the video lesson multilaterally.2.Analysis of Japanese Science Lesson VideosThe ninety five science lessons that were randomly selected and videotaped in the IEA/TIMSS-R Lesson Video Study throughout Japan in 1999 to 2000 have been analyzed by Japanese expert science teachers based on our lesson video analysis method. There appeared multilateral effective teaching strategies as well as non-effective.Eight lessons have been organized as materials of lesson videos and other printed materials for the use of science teacher education.Four lessons have been translated into English and brought to US, Australia, and Czech Republic to collect data of evaluation of Japanese lessons by science teachers in those countries.3.Analysis of Foreign Science Lesson VideosSub-samples of science lesson videos of US, Australia, the Netherlands, and Czech Republic were translated into Japanese and have been analyzed by Japanese expert science teachers based on exactly the same method that were used for Japanese lessons.US science lessons were evaluated relatively higher than other samples in many evaluation categories, while Japanese science lessons were evaluated relatively lower than other samples in many evaluation categories.4.Application of Research Materials into Science Teacher EducationScience teacher education programs which use our developed method and materials under prefectural teacher education centers and universities of teacher education have been showing high effectiveness and satisfaction.
