특성화 고등학교 전자회로 응용 실습을 위한 단계별 수행중심 문제 해결 과제의 개발

Abstract

The purpose of this study was to develop learner-centered activities, enhancing qualitative effect in lesson when the students in specialized high school perform an application practice of electronic circuit. To achieve this, step-by-step performance-centered problem solving activities for ‘practical application of electronic circuits’ is needed. As students conduct these activities, they can gain abilities to perform activities in each step; their creativity, logical thinking, literacy, achievement, and adaptability will be enhanced. This research was conducted by following phases: preparation, development, and improvement. Results of the study were as follows:First, the activities which were developed can be helpful teaching materials for the application of the most basic three subjects in practice of electronics curriculum; electronic circuits, digital logic circuits, and electronic and computational application. Second, the activities which were developed were selected through experts’ comments which were based on the five selection criteria, creativity, logical thinking, utilization, completion, adaptability. We carried out the validity testing by experts and the preliminary and field tests by students for final selective activities. Third, the activities which were developed are carried out through the following four steps; ① ‘to understand the problems’, ② ‘to explore and develop ideas’, ③ ‘realization’, and ④ ‘assesment’. The activities consisted of detailed problem-solving activities in each step. Fourth, these activities are made for cooperative learning and discussion work, and make the students write portfolio. Finally, learner-centered challenging activities that enhance logical thinking and the class that the students participate in aggressively are carried out through the activities which were developed.
