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.
