Youn-Kyoung Lee. 2017. The Effect of Problem-Based Learning on Korean College Learners’ English Vocabulary Learning. Studies in Modern Grammar 96, 253-270. The present study aimed at examining the effects of problem-based learning (PBL) on English vocabulary learning in a Korean college context. In total, 52 students participated in the study. The PBL class (n=26) was assigned to the experimental group, and the non-PBL class (n=26) was the control group. Both group had the same curriculum. All participants had pre-and postvocabulary test, and 12 students participated in the follow-up interview. The results showed that there were significant differences between the two groups on the post-vocabulary test (p<.05). The PBL participants’ interview data revealed that PBL provided sufficient English conversation practice and opportunities of scaffolding. The findings suggest that PBL should be applied to foster Korean college learners’ ability of English vocabulary learning.
