Research Interests

Prof. Matsushita has a wide range of interests in second language teaching. At the moment he is mainly working on two fields: vocabulary studies and language program management. Vocabulary studies includes topics such as quantitative analysis of Japanese vocabulary, analyzing and controlling vocabulary load of texts, vocabulary testing, cognition and acquisition of Kanji and Japanese vocabulary, and first language effects on acquiring second language vocabulary. In the language program management study, Prof. Matsushita explores a general framework for establishing a new second language program. Specifically, in collaboration with Prof. Beuckmann and other PEAK colleagues, he tries to describe the logic model of PEAK Japanese language courses and evaluates the Japanese program as a case study. All of these studies are practical and useful in second language learning and teaching.
