The purpose of this study was to explore the effect of problem-based learning on the learning achievement for the unit, 'The experience of ‘Manufacturing technology and Problem Solving Activity’ in the middle school ‘Technology-home Economics’. The experiment was designed as true experimental design, randomized posttest-only control group design. Problem-based learning was applied to the experimental group whereas traditional learning was used on the control group. Post evaluation scores were obtained from learning achievement tests given to two groups. The scores were verified at the level of .05 significance by independent sample test through SPSS/sin 12.0 program. The results of this study are summaries as below. First, It is shown that learning achievement of the experimental group, which took the problem-based learning treatment, is higher than the that of the control group, which received traditional group learning. The results of t-test results is statistically significant. Second, It is shown that learning achievement of the divergers․assimilators․convergers․accommodators learning styles of the experimental group, which took the problem-based learning treatment, is higher than the that of the divergers․assimilators․convergers․accommodators learning styles of the control group, which received traditional group learning. The results of t-test is statistically significant. Third, It is shown that learning achievement of the entering behavior 0-20%, 21-80%, 81-100% of the experimental group, which took the problem-based learning treatment, is higher than the that of the entering behavior 0-20%, 21-80%, 81-100% of the control group, which received traditional group learning. However, t-test results are only significant entering behavior 21-80%, 81-100% and entering behavior 0-20% is not significant. In summary, this study gives evidence that problem-based learning helps to promote learning achievement for ‘The experience of ’Manufacturing technology and problem solving activity’ from the middle school ‘Technology-home economics’. In addition, it is verified that learning style have impact on learning achievement.

이 연구의 목적은 중학교 ‘기술·가정’과 ‘제조기술체험과 문제해결활동’단원에서 문제기반학습이 학업성취도에 미치는 효과를 알아보는 데 있다. 이를 위하여 경기도 Y중학교 3학년 학생 중 교내동아리 참여 학생을 실험집단과 통제집단으로 구성하였다. 실험은 진정 실험 설계 중 임의배정 통제집단 사후검사 설계이며, 실험집단에는 문제기반학습을, 통제집단에는 전통적 조별실습을 처치하였다. 실험처치 후 두 집단에게 동일한 학업성취도 평가를 실시하여 유의도 .05 수준에서 독립표본 t-검정을 실시하였다. 그 결과 다음과 같다. 첫째, 실험집단이 통제집단보다 학업성취가 높으며, 이는 통계적으로 유의미하다. 둘째, 학습양식에 따라 실험집단과 통제집단의 학업성취를 비교한 결과, 확산·동화·수렴·조절적 학습양식 모두 실험집단의 학업성취가 높으며, 이는 통계적으로 유의미하다. 셋째, 출발점 행동에 따라 실험집단과 통제집단의 학업성취를 비교한 결과, 0-20%, 21-80%, 81-100% 모두 실험집단의 학업성취가 높다. 하지만 21-80%, 81-100% 집단에의 차이만 통계적으로 유의미하며, 0-20%집단의 차이는 통계적으로 유의미하지 않다. 그러므로 문제기반학습이 학습양식에 따라 학업성취도에 미치는 효과가 없다는 가설은 기각되었다. 이는 문제기반학습이 학습양식에 따라 학업성취도에 효과를 미침을 뜻한다.
