Hong Kong Government promote small class teaching. Most of the parents accept it because they think that can improve the level of learning. In facts, it is. The teachers can care their students more and know what they need so that the students may understand the knowledge more easily. Besides, small class teaching can abate the teachers' pressure because they look after less students and no need to mark corrections on so many students' works. However there has the other problem is small class teacher need more teachers to teach the students. First, it spends more money. Second, the demand of teacher increase but there may not have enough teachers in the society. Therefore a part of schools may need to employ some teachers that don't teach well. In this case, i don't think the parents will still accept small class teaching and I think the system of school are okay now.
