Abstract
The purpose of this study is to examine the effects of PBL (Problem-based Learning) strategy applied to the "Inorganic Chemistry Laboratory" class. Especially, the changes in 'self-directed learning ability' and 'attitudes toward science' of undergraduate students were examined. In addition, perception on PBL problem and the PBL classes were investigated. The results of this study were as follows: First, after the course, 'self-directed learning ability' and 'attitude toward science' of students were significantly improved (p < .05). There were significant improvements in every sub-categories except 'self-confidence as a learner' for 'self directed learning ability' and every sub-categories except 'usefulness of science' for 'attitude toward science'. Second, the students expressed that PBL strategy provided opportunities to learn self-directively and responsibly, but the process of defining the problem was difficult. Finally on the survey toward PBL strategy, the students responded that PBL problems were authentic and helpful to learn problem solving ability. In conclusion, PBL laboratory course is effective for developing self-directed learning ability and positive attitude toward science.
