Open Problem Solving In Junior High School Math Teaching Strategies

To make a research on the "problem-solving"teaching method is an important aspect of the mathematics quality education and also an important problem should be earnestly discussed in the mathematics teaching reform at present. The open-ended problem in mathematics is problem worth to be explored and studied for depth, different from the traditional exercises doing, is helpful to extend the creativeness and the ability of problem solving independently for the students. To integrate the opening problem-solving method into the mathematics classroom teaching and find out the teaching strategy for it is very urgent for the quality education. In this paper, four strategies of class teaching are investigated based on the theoretical discussion:1.Through specific problems solving explore and search the basic laws by induction. Then initiate new conjectures. There will be some quasi-theorems produced by deduction and apply them to more complicated problens; 2. Establish the cognitive structure with the known knowledge by imagination andanalogy. And then solve new problems under the new constution; 3. Find out new methods and from new concepts. Extend the concepts by the approach of looking for different new thoughts; 4. Solve the practical problem by investigating the real landscape. Design reasonable algorithm and find the problem solutions under the mathematical inferences. We also discuss the operat abiltity of the strategy through the practical teaching cases, We further conceptualize the teaching importance of the opening problem-sloving: 1. Beneficial to comprehend teaching function of opening problem; 2. Useful for the students to master the mathematics learning method and enhance their ability of mathematics problem-sloving; 3. Helpful for the students to understand the sources of mathematics problem; 4. Usefulto cultivate the students advancing spirits and strong will; 5. Fundem entail for the reforming of traditional teaching method.
