중학교 기술교육에서 기술적 수준에 따른 생산,통신 및 수송기술 분야의 문제 해결 활동 과제 개발

Abstract

The purpose of this study was to develop the problem solving hands-on activity according to the technological level for technology education in middle school. The study was developed by the following three stage: preparation, development, and improvement. In the preparation stage, the needs for hands-on activities were analyzed. Then themes of for hands-on activities were determined. In the development stage, the following steps were practiced; ① setting up the technological level of problem solving hands-on activity themes, ② setting up the goal of the hands-on activity according to the technological level, ③ organizing of problem solving hands-on activity according to the technological level In the improvement stage, ① the validity testing by experts, ② the preliminary test by students were carried out, and the problems were improved by result of evaluating. Results of the study were as follows: First, in this study, the following problem solving hands-on activity were developed that technological level of the problem separated 3 levels of the high, medium, low : ‘making an multi-articulation robotic arm’ as a production technology, ‘making a model car’ as a transportation technology, ‘making a communication panel’ as a communication technology. Second, developed problems consisted of the problem situation, activities, restrictions, tools & equipments, evaluation table, criteria, portfolio and so on. Evaluation were classified evaluation by teacher and students. Evaluation by teacher include the evaluation based on observations, portfolio, finished product. Evaluation by students comprised of self-appraisal, peer-appraisal.
