문제 중심 학습(PBL)을 적용한 ｢무기화학실험｣수업의 효과

Abstract

ABSTRACT. The purpose of this study is to examine the effects of PBL (Problem-based Learning) strategy applied to the ｢Inorga-nic Chemistry Laboratory ｣ class. Especially, the changes in 'self-directed learning ability' and 'attitudes toward science' of under-graduate students were examined. In addition, perception on PB L problem and the PBL classes were investigated. The results o fthis study were as follows: First, after the course, 'self-dir ected learning ability' and 'attitude toward science' of students were signifi-cantly improved ( p < .05). There were significant improvements in every sub- categories except 'self-confidence as a learner' for 'sel f directed learning ability' and every sub-categories except 'usefuln ess of science' for 'attitude toward science'. Second, the s tudentsexpressed that PBL strategy provided opportunities to learn self-directively and responsibly, but the process of defining the p roblemwas difficult. Finally on the survey toward PBL strategy, the students responded that PBL problems were authentic and helpful t o learn problem solving ability. In conclusion, PBL laboratory cour se is effective for developing self-directed learning ability and positive attitude toward science.
