Research of Computer Assisted Educational System for applying in Asynchronous Distance Education of Information Course through The Internet

本研究的目的是设计一个计算机辅助教学系统，在异步化的远程教育环境中，对被困学生进行推理，并给予他/她教育目标。研究中的问题是：需要什么样的数据来寻找考生，当系统中断了陷入僵局的学生，以及如何让陷入困境的学生实现他或她的教育目标，首席调查员设计了一个服务于第一学期和第二学期信息课程学习者的网络教育系统。从学习环境出发，Oda博士和Watanabe博士构建了一个软件，用于监控单个学习者的学习行为并存储他们的学习记录。通过数据分析和模糊推理机对网络学习者的行为进行评估，并对学习者是否陷入僵局进行判断，将评估结果用于支持教师的教学决策，使陷入困境的学习者达到教育目标。学习者并不总是意识到他或她的学习过程中的僵局。因此，这一结果可以作为教师对处于无意识僵局的学生进行选择的触发点。武内和平岛博士开发了一种支持协作学习的智能系统。Kuwada博士专注于多媒体系统中的教学导航技术。渡边博士进行了超级教室的实验，这是一个为100名学生服务的WWW学习环境的计算机网络系统。首席调查员在ICCE99计算机教育国际会议(1999年11月4日至7日，千叶)的第一天组织了一次讲习班。在研讨会上，约70名研究人员参加并交流了他们的理论知识和技术。

The purpose of the research is to design a computer assisted educational system which reasons an impassed student and gides him/her to the educational goal in the asynchronous distant educational environment. The problems in the research are what kind of data is required to find candidates, when the system interrupts the student who is in impassee and how to gide the impassed student to his or her educational goal,The head investigator have designed a web-based educational system which serves learners in the information course of first and second semestors. From the learning environment, Dr. Oda and Dr. Watanabe built a software which monitors individual learner's learning behavior and stores their learning records. From the data analysis and the fuzzy inference engine which evaluates web learner's behaviors and estimates whether the learner is in impasse, the estimated result is used for supporting teacher's pedagogical decision to gide the impassed learner to the educational goal. A learner does not always become aware of impasse in his or her learning processes. Therefore, the result can be used for the trigger of teacher's choice to the student who is in unconscious impasse.Dr. Takeuchi and Dr. Hirashima developed an intelligent system for supporting collaborative learning. Dr. Kuwada focused an instructional navigation technology in a multimedia system. Dr. Watanabe made an experiment of HyperClassroom that is a computer networked system of WWW learning environment and serves one hundred students. The head investigator organized a workshop in the first day of the International Conference of Computers in Education ICCE99 (4th - 7th, November in 1999, Chiba ). In the workshops, around 70 researchers participated and exchanged their theoretical knowledges and technologies.
