For the elementary Japanese language class, I use eLC only to upload files of huge size. I often have PDF files of manga pages to explain Japanese grammar in class and later I upload the files in eLC so students can download if they like. I just couldn't find a better way to do this. This works well so far.

I was also thinking of using eLC to keep my grade book for quiz, tests, participation, and other assignments. But I have too many quizzes and tests and I take attendance almost everyday. So I figured it is too overwhelming to have every grade record (like the grade of every quiz and test) in a single "grade" page in eLC. I decided to stick to my old way of keeping grade, which is excel spreadsheet file. Near the end of the semester, I will use the eLC grade book feature to show students' current grade. I do this because last semester many students asked me by email about their grade and I had to tell each one every time. It was just so time consuming!
