Abstract
From the perspective of word usage, we created questions to teach not only vocabulary but also grammar, including particles and other concepts. Through an analysis of the group discussions in class, we explored their efficacy and areas for improvement. As a result, students learned about key vocabulary learning concepts such as grammatical contexts and became familiar with using corpora to look up word usage. However, we also found the need for some fixes, including the fact that there were some aspects that they were not sufficiently aware of because the questions were biased.
