Study On Problem Solving Of Plane Geometry Teaching

Since NCTM presented the slogan"problem solving"in the 1980s,"problem solving"has become a research emphasis in the field of international Math Education, and it has become a fashion with the development of Math Education. Especially,"problem solving of subject"has become a research emphasis. Based on lots of"problem solving"and the importance of plane geometry in the Math Education of middle school, the paper discusses four important research objects in"problem solving"of plane geometry teaching: conception teaching, proposition teaching, method teaching and CAI of plane geometry teaching. In the end, the author presents the outlook of geometry teaching in the future, there are five parts in the paper.Part one. It discusses the foundational effect of conception teaching in the"problem solving"of plane geometry teaching and analyzes the psychological foundation and logical foundation of conception teaching from pedagogy and psychology, The author presents some views and advice on conception teaching of plane geometry teaching.Part two. It discusses the key effect of proposition teaching in the problem solving of plane geometry teaching. First, proposition teaching and conception teaching are relevant. That is to say, conception is important to grasp proposition, and proposition helps students understand conception. Second, proposition teaching is the key phase to improve the ability of problem solving.Nowadays, Great changes have taken place at the education idea, with the discussion to the psychological foundation and logical foundation of proposition teaching, the author presents some viewpoints about plane geometry proposition teaching.Part three. It discusses the important role about method teaching in the plane geometry problem solving. Some people think plane geometry is very difficult to learn, there are some factors, such as .objective factors, subjective factors, cognition and method factors, However, No good ways are an important factors. So the part will discuss the method teaching of the plane geometry problem solving.Part four. It discusses CAI of plane geometry teaching and the importance of CAI in plane geometry teaching.Part five: It discusses the outlook and expectation to the"problem solving"of the plane geometry teaching in the future.
