Mobile user behavior and attitudes during story-based kanji learning

摘要

We report on the usability and usage patterns of a mobile system designed to help students learn Ja panese kanji charac ters through a mnemonic-story method Our data comes from two sources: (1) a usability questionnaire of ka nji learners, and (2) from a series of two-week experiments where subjects used our mobile kanji learning system We found that 21% of mobile device usage actually occurred in a mobile learning setting We also found varied time- of-day usage patterns over a two-week period We d iscovered that user behaviors while using the system – selection operations, story creation time and story length – were c haracterized by positively-skewed distributions that can be described by exponentia l and lognormal models We found statistica lly significant correla tions between certain user beha viors a nd certain self-reported user attitudes. These results empirically clarify and confirm the usability of our mobile stor y-based kanji learning system Questionnaire data from a separate population of story-based kanji learners, who did not use our device, provides further insight into the study behaviors and requirements of story-based ka nji lea rners
