Developments of Integrated Curricula in Science Education and Intelligent Computer-Assisted Instruction System with Japanese Text to Speech Synthesis Mechanism

1.学生科学认知形成过程与综合科学教育课程开发的调查。(1)课程开发注重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，通过中小学实验/调查-分析-结果阶段的数据-信息-知识-评价，支持学生获得科学的概念和调查能力。(2)创建具有新属性结构的教材数据库模型和数据库：与传统的面向内容的数据库不同，我们开发了新型教材数据库，通过四个层次的属性结构：家庭(内容)-类别(公式或组合)-模板(熟悉的算法或程序)-子模板(作业命题)，能够更有力地预测学生的解题过程和理解特征。开发智能对话计算机辅助教学系统，帮助提高学生和教师的能力。将计算机辅助教学软件系统与文语转换设备相结合，构建了智能对话计算机辅助教学系统。学生可以在新的计算机辅助教学环境下学习，不仅可以阅读文本，还可以接收来自任意日语文本的音频信息。(1)该会话式计算机辅助教学系统已成功地应用于对外日语教育计算机辅助教学中。(2)另一个系统已经成功地应用于更具智能性的在职和职前教师培训系统，通过与专家教师模型的对话，提高他们推理和理解学生知识和理解的能力。

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.
