Abstract
The purpose of this paper is to clarify students' thought structure in an assembly session of a manufacturing class. The question items were developed on the basis of a preliminary investigation, which was carried out on 493 junior high school students. As a result of a factor analysis, five factors were extracted: "F1: Practice on assembling work," "F2: Identification of parts," "F3: Examination of tools/assembling," "F4: Inspection and revision of parts," "F5: Prospect of assembling." A thought structure model was developed on the basis of the unity of thoughts, and the allied structure between the five factors was examined. From the results, it can be concluded that starting from the thought about parts (F2), thoughts about the preparation for assembling (F3, F4, and F5) have an influence on the thought about the practice session (F1).
