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

本研究的目的是开发一个基于临床教育知识的多媒体系统。我们知道，通过对教学事件的认知和教学技能的适应来进行反思性思维，对于教师实际操作能力的发展是至关重要的。因此，本研究试图开发的VOD系统，既可以灵活地获取许多关于教案的信息，又可以反映自己的教案，按照自己的节奏重写教案。该系统由三个模块组成，以小学日语为主题。(1)主页是用html编写的，供实习教师使用。主页包括课本内容、教案(对象、单元、主题、课程流程图等)、协议和课程的mpeg编码视频。(2)Perl描述的公共入口界面，当点击每个终端主页上设置的链接时，记录数据。它被命名为“Checked CGI”。(3)Perl描述的公共网关接口，将数据请求记录转换为所选终端上的数据请求图表，并以可视化方式呈现。它被命名为“请求浏览CGI”。使用该系统，我们发现了以下几点。(1)实习教师对教案的制定进行反思。(2)该系统直观地展现了师范生的数据需求模式。分析后的图表向我们展示了实习教师的需求。(3)实习教师需要的是与教案相关的主题理解信息，而不是关于学生兴趣的信息。(4)这些分析图表包含了文本信息和视觉信息之间的关系，有助于超文本的二次开发和优化。

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.
