Development of Evaluation System for Teaching Materials Using Fuzzy System

调查了什么样的东西适合作为小学生或初中生日常生活的素材。1：材料的提取(1)从小学理科教材和教学手册中所描述的内容中提取材料。大约有800件。利用它们进行了预备性调查。最后，这些项目被精心挑选成大约200个项目。(2)初中也是一样，将材料提取出来。大约有1000个项目。最后，这些项目经过精心挑选，约200项。调查对象为657名小学生和1186名初中生。(3)数据分析对定期调查的数据进行量化分析。提取了学生对教材选择的偏好的三个轴。通过将分析得到的每种材料的权重作为材料的隶属函数，构建了能够适应模糊系统理论的材料数据库。通过隶属函数从该数据库中提取出符合学生需要的资料成为可能。(1)运用FSM方法，设计了通过教师的观察，提取学生对科学课的看法的方法。它能够开发出一种方法，来确定老师是否在科学课上得到了学生想要的东西。(2)该分析可以通过改变一个参数来提取多个结构。通过这种方法，人所具有的感性基本上能够反映到意识的结构上。

What kinds of things were appropriate as materials with regard to a daily life to students in an elementary school or a junior high school were investigated.1 : Extraction of Materials (1) Materials were extracted out of the contents that were described into science textbooks and the instruction manuals in an elementary school. There were about 800 items. A preparatory investigation was carried out by using them. Finally those items were selected carefully into about 200 items. (2) Similarly in junior high school, materials were extracted out. There were about 1000 items. Finally those items were selected carefully to about 200 items. The subjects were 657 children in elementary schools, and 1186 students in junior high schools. (3) Data Analysis The data of regular investigation were analyzed using the theory of Quantification No.3. Three axs on the selection of teaching materials that learner preferred were extracted. Also, the material data base that was able to adapt to a fuzzy system theory, by making the weight of each material that was obtained by this analysis a membership function of the material, was constructed. A material corresponding to the need of a student becomes possible to be extracted by a membership function out of this data base.2 : Extraction of Students' View toward Science Lesson (1) The way of extacting students' views toward Science lesson though a teacher's observation was devised by using FSM method. It was able to develop the method that constructs whether a teacher is receiving what a student wishes with a Science lesson. (2) This analysis is able to extract several structures by changing a parameter with a process of it. By this method, the sensibility that a human has basically is able to be reflected to the structure of consciousness.
