I have two classes to teach on Tuesday.
The first lecture starting from 9 AM is for graduate students, fifty in number. There are a few students from Asian countries, like China, Malaysia, and Vietnam. One student is from Nepal, who entered the university this April and does not understand Japanese at all.
Therefore, this year, I am teaching the class in Japanese and English. I prepared documents both in Japanese and English. I normally write on a board in English, adding some Japanese technical terms. I speak 80% in Japanese and 20% in English. Quizzes in English.
I did not know whether this plan would work, but so far students seem to enjoy it. The only problem is that I needed to reduce the contents by 10% because of using two languages. However, teaching less would mean understanding more. If so, everything is going well.
