项目摘要

1. Investigation of Students' Formation Process of Scientific Cognition and Curriculum Developments of Integrated Science Education. (1) Curriculum development attached importance to students' investigation process and knowledge Structure : We constructed the curriculum design model for promoting students' information utilization competency, and developed special statistics education curricula to support students that acquire scientific concepts and investigation competency through data-information-knowledge - evaluation in experiment/survey-analysis-result stages in elementary and secondary school levels. (2) Creation of instructional material database model and databases with new attribute structures : Indifferent of traditional content-oriented databases, we developed new types of instructional material databases that can be able more powerfully to predict students' problem-solving processes and understanding traits by the attribute structures of four levels ; family(content)- category (formula or combination) -template(familiar algoriths or procedures)- sub-template(assignment proposition).2. Developments of Intelligent Talking CAI System to assist improving Student and Teacher Competency. The intelligent talking CAI system have been constructed by combining CAI software systems and text to speech synthesis devices. And students can do learn under the new CAI environment only reading texts but also being able to receive audio messages from arbitrary Japanese texts. (1) One application of this talking CAI system have been effectively used to the Japanese language education CAI for foreigners. (2) Also, another system have been successfully applied to the more intellectual in-service and pre-service teacher training system for improving their competency to infer and comprehend student's knowledge and understanding trits though dialogues to expert teacher's models.

1.学生科学认知形成过程调查与综合科学教育课程开发。(1)课程开发重视学生的调查过程和知识结构：构建了促进学生信息利用能力的课程设计模式，开发了专门的统计教育课程，支持学生在实验/调查-分析-结果阶段通过数据-信息-知识-评价获得科学概念和调查能力。(2)教材数据库模型的建立和新属性结构数据库的建立：与传统的面向内容的数据库不同，我们开发了新类型的教材数据库，通过四个层次的属性结构，能够更有力地预测学生的问题解决过程和理解特点;族（内容）-类（公式或组合）-模板（熟悉的算法或程序）-子模板（作业命题）。开发智能语音CAI系统，以帮助提高学生和教师的能力。将CAI软件系统与文语合成设备相结合，构建了智能说话CAI系统。在新的CAI环境下，学生不仅可以阅读课文，还可以接收来自任意日语课文的音频信息。(1)该语音CAI系统已成功应用于对外日语教学CAI中。(2)此外，另一个系统已成功地应用于更智能的在职和职前教师培训系统，以提高他们的能力，推断和理解学生的知识和理解trits通过对话专家教师的模型。
