Abstract
This paper reports on a trial of the "Grammar Learning Video" developed as an online Japanese learning material for beginners. Video viewing was implemented as a prior learning assignment in two classes. Based on questionnaire responses, the learners' impressions were analyzed from three perspectives: 1) usefulness, 2) sense of burden, and 3) slide design. Although the online materials themselves received a high evaluation, further refinement is needed to reduce the learners' sense of burden.
