This study surveyed 75 CALL effectiveness research papers published in major journals in Korea for past 5 years. Each research paper was classified according to 7 categories: Research design used, educational setting, number of participants, term of a study, technology used, language taught, and language skill or area taught. The results showed that there were more non-experimental studies than experimental studies, investigations in tertiary settings dominated the field, and the technologies used were largely web-related ones. This study looked at both strengths and weaknesses in this body of work and revealed a positive trend towards combining quantitative and qualitative methods. Recommendations for future research were offered.
