A study on the development of multi-media for teachers' practical skills based on educational clinical knowledge

本研究旨在开发一个基于临床知识教育的多媒体系统。教师通过对教学事件的认知进行反思性思考，以及对教学技能的适应性调整，对教师实践绩效的发展至关重要。因此，本研究尝试开发一套能让学生灵活存取教案资讯，并能反映自己的教案，以自己的步调改写教案的视频点播系统。该系统由三个模块组成，其中包括小学日语科目。(1)主页是用html编写的，供学生教师使用。主页由教材内容、教案（对象、单元、主题、课程流程图等）、协议和MPEG编码视频的教训。(2)Perl描述的公共门接口，当点击每个终端上的主页上的链接时记录数据。它被命名为“检查cgi”。(3)Perl描述的公共门接口，将数据请求记录转换为所选终端上的数据请求图表，并将其可视化。它被命名为“请求浏览cgi”。使用这个系统，我们发现以下几点。(1)实习教师对教案的制定进行了反思。(2)该系统将学生教师的数据需求模式可视化。分析图表显示了实习教师的需求。(3)实习教师需要的信息是了解与制定课程计划有关的主题，而不是学生的兴趣。(4)这些分析的图表包括文本信息和视觉信息之间的关系，是有用的超文本表示的二次开发和优化。

The purpose of this study is to develop a muti-media system based on educational clinical knowledge. It was known that reflective thinking through cognition of teaching and learning events and adaptation of teaching skills are most important for the development of practical performance for teachers. So, this study try to develop the vod system that allow a flexible access to many information about lesson plan and also reflect their own lesson plan, rewrite the plan with their own paces. This system was constructed from three module with a Japanese subject for elementary school. (1) The Home Page is written in html for the student teachers' use. The home page consists of contents of a textbook, a lesson plan (object, unit, subject matter, flow chart of lesson etc.), protocol and a MPEG code video of the lesson. (2) Common gate interface described by Perl that records the data when the link, setting on the home page on each terminal, is clicked. It was named "checked cgi". (3) Common gate interface described by Perl that changes the data request recording into the data request chart on the selected terminal and present it visually. It was named "request browse cgi". Using this system, we find the followings. (1) Student teachers made reflect thinking for making lesson plan. (2) This system visualizes the pattern of the data reuest from the student teacher. The analyzed chart shows us the student teachers' demands. (3) The student teacher demands information for understanding the subject matter related to making a lesson plan rather than the information about student's interest. (4) These analyzed charts that include the relationship between text information and visual information are useful for redeveloping and the optimization of Hyper-text presentation.
