Abstract
A corpus function that provides information on collocations and example sentences is effective for Japanese learners when they write compositions. However, if the actual word searched for in the corpus tool does not fit the context of the composition, then such effectiveness cannot be on full display. At present, authors are aiming to develop teaching materials to train skilled users of corpus tools; meanwhile, we believe there is also a need for research on dictionary usage among learners. As such, this study conducted a questionnaire survey with 307 beginning to advanced learners and analyzed the results to reveal how learners actually use dictionaries when writing short compositions or essays and what problems they experience with dictionaries.
