Supporting System for Developing Instructional Materials of "Information Study" based on Learning Model of Information Literacy

本研究的目的是建立一个典型的高中学科领域的“信息学习”教学模式，并开发一个支持教师的系统。在这个过程中，我们提出要教会学生“信息化、系统化的思维”，促进“科学地理解信息”。具体来说，这项研究是在三个领域进行的。研究结果如下：(1)针对“问题解决能力”领域，制定了教学计划和教材，并实施了实验课。通过分析学生在课堂上的反应，探讨了评价学生“信息思维”和“系统思维”习得的方法。基于JAG(教学活动游戏)开发了一个包含评价方法思想的教材开发环境，并利用该环境创建了模型教材。此外，还审查了编写类似材料的教师培训课程，并以光盘形式出版。(2)关于“表达和交流”领域，编写了一份关于IAG的教材，采用了与“解决问题能力”领域相同的方法。(3)针对“信息道德”领域，开发了一种教学方法，引导学生进行适当的决策，将“伦理知识”、“信息技术知识”和“理性判断知识”结合起来，以“信息化、系统化思维”取代“信息和系统思维”。通过实验证明，该方法比通常的让学生从案例中学习的方法更有效。(4)开发了以试题库BBS为主的教材开发支持系统。

The purpose of this research was to build up a teaching model typical for "Information Study" established as a high school subject area and to develop a system to support the teachers. In the process, we proposed that students should be taught "informatical and systematical thinking" to promote "scientific understanding of information". Specifically, the research was conducted in three fields. The followings are the results in each field:(1)Concerning "problem solving ability" field, teaching plans and materials were developed, and then trial lessons were implemented. By analyzing the students' reactions in the lessons, a method to evaluate the acquisition of "informatical and systematical thinking" was investigated. A teaching material development environment, which includes the idea of the evaluation method, was developed based on JAG (Instructional Activities Game), and model materials were created with it. Furthermore, a teacher-training curriculum to create the similar materials was examined and published in CD-ROMs.(2) Concerning "expression and communication" field, a teaching material used on IAG was developed with the same approach taken in "problem solving ability" field. Additionally, as the prerequisite of this material, individualized learning materials focusing on "knowledge and understanding" and "skills and expressions" were developed.(3)Concerning "information morals" field, a teaching method was developed to guide students to appropriate decisions by letting them combine "three sorts of knowledge"; that is, "ethical knowledge", "knowledge regarding information technology" and "knowledge of rational judgment", with which "informatical and systematical thinking" was replaced. Through experiments, this method was proved to be more effective than the usual method of letting students learn from cases.(4)In addition to above, teaching materials development support system, which mainly consisting of a test items database BBS was developed.
