Abstract

The purpose of this paper is to develop evaluation methods in order to apply effective problem-based learning (PBL). To observe the effectiveness of a PBL system on learners and to comprehend the learning process of a PBL application, analysis of reflective journals and an evaluation questionnaire completed by participants (n=68) were used. The participants of the study were recruited from Hankyong National University students who undertook first-year Creative Engineering Design. A total of four problems for the PBL-based lectures were designed and applied to 12 weeks of PBL lectures. The participants completed reflective journals upon completion of each PBL problem-based activity; upon completion of the last PBL problem, participants completed and submitted a PBL system class-evaluation questionnaire. Also the participants completed an evaluation questionnaire at each step of the instructional procedures for each PBL problem-based activity. The findings of the research show that the participants increased their comprehension of PBL systems, their understanding of lecture content and of cooperative learning, and improved their self-reflection, authentic experience, creative problem-solving skills, communication skills, documentation skills, presentation skills, observational skills, and evaluation skills. The participants described how learning through PBL increased their confidence, satisfaction, and sense of achievement, compared to the previous semester.

본 논문의 목적은 효율적인 문제중심학습을 적용하기 위한 평가방법을 개발한다. 연구 대상은 창의공학설계 교과목을 수강한 H대학 1학년 학생 68명 이었으며, PBL수업은 12주에 4개의 PBL문제를 적용하였다. PBL의 효율성을 관찰하기 위하여 학생들은 주어진 문제의 PBL 활동 과정에서 평가지를 작성하여 제출하였다. 또한 PBL 활동이 끝날 때 마다 평가지와 성찰일지를 작성하여 제출하였다. 연구 결과는 PBL에 대한 이해, 학습 내용에 대한 이해, 협동학습에 대한 이해, 자아성찰, 실제적 경험, 창의문제 해결력, 자기주도적 학습 능력, 의사소통 능력, 문서작성 능력, 프리젠테이션 능력, 관찰 능력, 평가 능력과 같은 다양한 PBL의 효과를 경험한 것으로 나타났다. PBL 활동에 대해서는 지난 학기에 비하여 자신감, 만족감, 성취감도 높았으며, PBL 수업이 매우 유용했다고 응답했으며, 수업에 대한 만족도도 높았다. 그러나 PBL 활동 과정에서 팀원들 간의 의사소통문제, 함께 모이는 문제, 적극적으로 참여하지 않는 팀원 문제, 시간이 소용되는 문제가 나타났다.
