The purpose of this study was to examine the relationship among core competencies
(cognitive, affective, and social), behavioral regulation competence, and Korean language
achievement. The proposed path model posits that cognitive, affective, and social competencies
influence the level of behavioral regulation ability which in turn influence Korean language
achievement. The model was tested with 212 girls' high school students in Korea. Path analysis
was employed to examine the relationship among the variables. The results were as follows.
First, the overall goodness-of-model fit was evaluated as acceptable. Second, cognitive
competencies, and behavioral regulation abilities had significant direct effects on Korean
language achievement. Third, cognitive, affective, and social competencies had significant
indirect effects on Korean language achievement. These indicate that the Korean language
curriculum may have a direct relationship with cognitive, affective, and social competencies. In
addition, the learning process variables, such as behavioral regulation ability, were considered
to enhance Korean language achievement. This study has significance in that it examines the
current Korean language curriculum of Korea and provides guidance for the future Korean
language curriculum.
