The present study compared students' scores on their responses to an essay exam question in a content course with (a) three vocabulary-related objective indices and (b) holistic evaluations of the responses as Japanese compositions by Japanese language instructors. The results showed that the total number of morpheme tokens had the highest correlation with the course instructor's ratings. What this implies is the importance of expository skills to produce an extensive discussion using a large number of words. This, in turn, requires vocabulary skills, although in the context of L1 learning and instruction, vocabulary development has not been given much attention. It is suggested that we rethink the role of vocabulary instruction in Freshman Japanese courses, especially academic vocabulary development.
