Abstract
Following face-to-face JSL lessons in which particles were presented with the images that L1 users would associate with each of them, we developed online materials to further help learners internalize what they learned. A post-test revealed that beginning students' scores improved regardless of the use of the online materials. On the other hand, intermediate and advanced students' scores did not improve after using the online materials, although those who attended the face-to-face sessions scored higher than those who did not. The result of a student survey suggested that the online materials would be improved with sound, more explanations and exercises.
