In creating the multiple-choice character form quiz, we explored which kanji were suitable as distractors by having learners actually take the quiz and answer a questionnaire. First, regarding the usefulness of the quiz, many said that it helped them recall the kanji they had learned. Many advanced-level learners said that it helped them notice the differences in shape from other kanji, and that it made it easier to remember kanji in relation to similar ones. Next, regarding the kanji choices, many intermediate-level learners emphasized the effectiveness for reviewing lessons, rather than the high similarity in form between choices, and many advanced-level leaners emphasized that the kanji should be frequently used.
