In this study, an attitude survey using rating scales was conducted with 111 Japanese language learners. This was done to examine what kind of design is desired for their understanding in terms of Japanese language learning materials. As a result, “underlining” was statistically desired in input enhancement techniques which emphasize the key language form. Also “photos” was statistically rated higher than “drawings.” In addition, the results reveal that learners consider “explanation about grammar,” “correct usage / example,” “incorrect usage / example,” “icon / pictogram,” “table,” “summary,” “numbering learning contents,” and “captions” as useful to facilitate their understanding. Based on the results, this study proposes a model design of learning material as a draft plan.
