| Research Abstract |
The present study investigated effect of new curriculum on ratio concepts. The curriculum was composed of two aspects : the one was to introduce "logic of children" on the concepts. The other was to make clear concrete cognitive barrier from preventing understanding of children. The target children was fifth graders in a public elementary school. They were compared with pupils who were taught the concepts according to typical textbook on math. Intervention lasted about three weeks. As results, pupils in the experimental condition indicated better understanding in problem solving on ratio concepts, in judgment on magnitude or meaning of ratio concepts than control children. Thus, this study demonstrated that new approach based on the "logic of children" promoted understanding very hard concepts to learn.
