공업계고등학교‘공작기계Ⅰ’CAD수업에서 JigsawⅡ협동학습이 학업성취도에 미치는 효과

Abstract

The purpose of this study was to verify the effects of JigsawⅡ cooperative learning on academic achievement of Computer Aided Design(CAD) instruction, the Machine Tool Ⅰ subject of technical high school. To verify the hypotheses of this study, 2 parts(16 students in each part) of the first grades from technical high school in Cheong-Ju were selected. Each part was divided into three sub-groups by the level of entering behavior levels. Static-Group Comparison Design was applied for experimental planning. The content of the experiment was the CAD instruction in the Machine Tool Ⅰ textbook. The experimental group was taught using a JigsawⅡ cooperative learning method and the control group using a traditional teaching method. The independent variable was teaching method and the dependent variable was academic achievement. The data was analysed using a t-test with a significance level of 0.05 Significance level established prior to data treatment. The result of this study were as follows; First, the JigsawⅡ cooperative learning in CAD instruction had little effect on the academic achievement Second, the JigsawⅡ cooperative learning in CAD instruction had little effect on the academic achievement in the entering behavior levels. Finally, the JigsawⅡ cooperative learning in CAD instruction had little effect on the academic achievement in the cognitive and functional domain of the brain.
