Description

We have known from the teaching experience that many students meet firstly the difficulties in understanding on the problem of maximum and minimum in quadratic functions after they entered to senior high school. So we analyzed answer papers on quadratic functions and knew that the main reasons of difficulties in understanding were caused by "complexity in dividing the intervals" and "illusion that the intervals and the graph of the quadratic functions were moving at the same time". We exploited teaching materials (so called "Kawaraban") and tools so that students could easily understand the problem above and we have individually guided four students with the teaching materials and tools. We found out that the methods were very useful for students to understand the problem.
