| In recent twenty years, with the development of the elementary education, newly different kinds of educational theories and teaching methods attract people's attention. But in the middle schools, traditional ways of study are rather single. Students only study knowledge in the books. With the help of the teachers, the students accept plenty of indirect experience passively. They are short of direct experience. This makes lots of the students have strong consciousness of hating study. Students' creative ability can not be well cultivated and developed.According to the ideas of the new curriculum reform, the cases in this thesis aim at using certain concrete mathematics knowledge, setting up certain studying situation and choosing proper ways of study to make the students have direct experience. In this way we can change the traditional ways of teaching in which direct experience is short.By the study of the mathematics teaching cases, it can be found that if the students study by both indirect and direct experience, then they can get complete experience. It can not only make the students form the mathematics skills , improve the students' interest in study, but also help the student master knowledge well. Otherwise, it can cultivate the students' creative ability. |
