The Retraining Program for teacher is the most urgent problem since the arithmatical curriculum has been revised by the Education Department in 1973 in terms of modernization of mathematics. The content of the Retraining Program has not been well carried out because of various constrained conditions. It will be very useful for teachers to be reeducated when I evaluate the present situation carefully. My elaborate evaluation show that primary school teachers lave very scant knowledge of the conception of set theory. In my paper I could point out several misunderstandings of set theory. I hope this pager can be of help to teachers as well as the retraining program.
