This study explores teacher's corrective feedback types in an error treatment sequence in Korean EFL classroom setting. Corrective feedback moves are coded as explicit correction, recast, or initiations to self-repair. The frequency and distribution of each corrective feedback type are examined. But the special focus was given on feedback types eliciting learner's self-repair (clarification request, metalinguistic feedback, elicitation, and repetition of error) because initiations to self-repair are believed to facilitate language learning more than other strategies. The results of the study are as follows. First, there was an overwhelming tendency for teacher to use recasts whereas initiations to self-repair were not used as much as recast (52.4% vs. 29.5%). Second, the teacher tended to select feedback types in accordance with error types: namely, recasts after phonological, lexical, and translation errors and initiations to self-repair after grammatical errors though the differences were not significant. Finally, teacher's belief and students' expectation on corrective feedback were compared with actual corrective feedback representations respectively and some mismatches were found. Though both teacher and the students acknowledged the importance and necessity of self-repair, self-repair were not put into practice as such. Therefore, this study suggests more initiations to self-repair be used for effective language learning.

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.
