In my experience, 20 is the maximum class size for a realistic and feasible conversation class. For writing classes 18 is a realistic maximum, and 20 for reading. In contrast, the Ministry of Finance wants to rule over the education ministry and tell them to up the class sizes to FORTY! Utterly ridiculous. As a child, the largest class I was in was 30, and that was the legal maximum. Japan is already the lowest ranked country for TOEIC in Asia, and the education in this country is quite poorly funded, and teachers have a terrible time professionally. The ministry of finance has belief it can dictate education policy. I say we should push against this, and use this opportunity to bring the class maximums down further to 30, and demand improved investment into the next generation of leaders and workers for this country. At least support this petition at Change.Org.
