분수의 곱셈·나눗셈에 관한 연구 = A Study on the Fractional multiplication and division

다국어 초록 (Multilingual Abstract)

Generally, in the five fields of mathematics teaching, the higher grade the elementary students becom, the more they have resistances because of heavy relative difficulties, and they make many mistakes.
According to recently fraction teaching, teachers helps that the students may gather more fragments of knowledge on the fraction, because there described not any frame of fractional concept but in the text.
In this point, through the fabricated contemplation, it seems to be more proper that students solve the difficult ones. So teaching them the fractional multiplication and division by the following courses, they could have clearer fractional concept and made less mistakes in calculation.
1. To learn the Fractional multiplication by the concrete picture operation.
2. To learn the fractional multiplication by a perpendicular line.
3. To learn the fractional division by the fractional multiplication relation.
4. To learn the fractional division by the inclusions.
5. To find out and learn the method of computation of the fractional multiplication and division by the inductive reasoning.
