The purpose of this study was to examine the difference of problem-solving ability according to student's level of self-efficacy. Participants were 72 junior students who took the course 'Environmental Instrumental Analysis'. Before the PBL activities, students were given the self-efficacy tests to all students. Among them, 44 students(30% of each high and low ranking) were selected and encouraged to complete pre-problem solving tests. The PBL was conducted for 12 weeks using blended learning strategies. After the PBL, 44students completed post-problem solving tests. Results showed that there were differences of problem-solving ability according to student's level of self-efficacy. From the results, instructional strategies for promoting students' self-efficacy should be employed for enhancing problem-solving ability in PBL activities.
