The differences in adolescents' decision making abilities according to the level of critical thinking in terms of practical problem-based instruction of Home Economics

실천적 문제중심 가정과 수업에서 청소년들의 비판적 사고력 수준에 따른 의사결정 능력의 차이

The Purpose of this study was to find out whether there was any difference in adolescents' decision making abilities according to the level of critical thinking in practical problem-based instruction of Home Economics. The subjects of this study ware 147 students from K girl's high school in Daegu. They were divided into two groups. The former was the experimental group, which took' practical problem-based instruction' of Home Economics. The later was the control group, which took the typical lecture-based instruction. Factor analysis, Cronbach ${\alpha}$, correlation, and two-way ANCOVA were Performed for data analysis. The results of this study are as follows: First, there was no significant difference in the steps of problem identification and information search of the decision making according to teaching methods and the level of the critical thinking ability. Second, the adolescents who took the practical problem-based instruction had shown more improvement in the steps of alternatives consideration and value of the decision making ability than those who took the typical instruction. Third, the adolescents with the high level of critical thinking ability have made much more improvement than those with the low. And it was found that in the case of adolescents with the low level of critical thinking ability, those who took the practical problem-based instruction have made much more improvement than the others who took the typical instruction. On the other hand, in the case of adolescents with the high level of critical thinking ability, those who took the typical instruction improved much more than the others who took the practical problem-based instruction.

본 연구의 목적은 '소비 생활' 단원의 실천적 문제중심 가정과수업에 있어 비판적 사고력 수준에 따른 청소년의 의사결정능력의 차이에 대해 알아보는 것이다. 본 연구의 대상자는 대구 K여고 147명의 학생들로 2개 학급 학생들에게는 전통적 강의식 수업을 실시하고, 3개 학급 학생들에게는 실천적 문제중심 수업을 4주간에 걸쳐 학급별로 총 8차시의 실험수업이 이루어졌다. 본 연구에서 자료 분석은 적률상관관계 분석과 이원공변량분석을 실시하였다. 본 연구의 결과 실천적 문제중심 가정과수업을 받은 청소년이 전통적 강의식 가정과수업을 받은 청소년보다 대안단계와 가치단계에서의 의사결정능력이 더 많이 향상된 것으로 나타났으며, 비판적 사고력 수준이 높은 청소년이 낮은 청소년보다 평가단계의 의사결정능력이 더 많이 향상된 것으로 나타났다. 또한 비판적 사고력 수준이 높은 청소년들에게 있어서는 강의식 수업이 평가단계의 의사결정능력 향상에 더 효과적이나 비판적 사고력 수준이 낮은 청소년들에게 있어서는 실천적 문제중심 수업이 평가 단계의 의사결정능력 향상에 더 효과적 인 것으로 나타났다.
