As Japanese undergraduate classes are mainly conducted as lectures, foreign students studying in Japan must have adequate Japanese language skills in order to participate, and STEM students in particular need to be able to understand mathematics lectures. However, very few foreign students are accustomed to hearing mathematics lectures conducted in Japanese prior to their enrollment. The author of this study researched problems that foreign STEM students encounter when listening to video lectures on mathematics. Participants encountered difficulties in five main areas (1) problems caused by instructor's explanation (2) problems caused by instructor’s writing (3) problems caused by their mathematical reasoning (4) problems caused by their mathematical knowledge (5) problems caused by observer’s mathematical oral expressions.
