Many teachers and researchers believe learning preferences or learning styles can be used advantageously to enhance language study and motivate learners. Following an overview of Gardner's theory of multiple intelligences (MI) and research on multimedia-based approaches in foreign language instruction, this paper first describes a study comparing students' learning preferences, obtained through an MI inventory survey, to their listening scores before and after CALL instruction. The correlation between students' MI scores and listening scores is then analyzed, determining whether their MI was improved by CALL instruction, and if so, which MI and to what degree. This is followed by a discussion on how language learning software could be implemented to increase students' use of multiple learning styles. It is concluded that CALL software can be effectively used to enhance the many kinds of human intelligences employed when learning languages. (Contains 2 figures, 6 tables, and 4 online resources.)
