Areas of Expertise

Second Language Acquisition, Applied Linguistics.


Ryoko Osada became interested in theories of Second Language Acquisition (SLA) through teaching Japanese. However, there might be some separations or gaps between theories and pedagogy in SLA. In addition, the amount of data a researcher could collet would be limited, whereas corpora allow us a considerable amount of data. Her research interest is to reveal tendencies by examining data from language learners’ corpora and suggest pedagogies that would help learners of Japanese language.

Teaching Interests

Ryoko Osada has been teaching elementary through advanced Japanese as well as Japanese literature both in the U.S. and Japan. Her focus is on adult acquisition of Japanese and language pedagogy relating to grammar, kanji, listening, speaking, writing and composition, with an emphasis on meeting the needs of learners through the development of context-appropriate teaching materials and class plans. She is also experienced in teaching business Japanese, both language and culture, in a higher education environment.
