| The reform of curriculum has been carried on for 6 years in Suzhou District, Gansu province, where the writer is engaged in full-time physics teaching and research. In over 20 junior high schools, we observed classroom lessons and had discussions in groups , aimed at exploring key problems that appeared in the physical classroom teaching and experiments in junior high schools.At last we make a conclusion of the key problems as follows: First, the target of exploring problems is not clear, second, there is much difference between teaching material design and students' background knowledge, third ,the teachers lack whole design of exploring teaching. And the students are so lacking in exploring skills for physics study that students' classroom study is inefficient in reality According to the goals for compulsory education course standard, requested to junior high school students' development, the writer makes sense practically that the efficient goals for the classroom experiment teaching are: according to the related theories, to design clear explorative goals ,to have a clear direction for teaching activities ,to design the best teaching content in accordance with the feature of teaching material, to develop a supportive strategy of having the students obtain the accomplishment of exploring according to the students' independence of explorative experiments and the teachers' instruction degree ,the teachers should try their best to set up the layer on content of explorative experiments. in order to increase practical opportunities for students, the teachers should try a varieties of major forms which are suitable for students exploring in classroom teaching reinforcing the increasing level of the students' thinking in explorative experiment teaching and the designing of problems for the students to solve are the main study strategies which will promote the harmonious development of using both their hands and brains in explorative experiments in classroom teaching.
