The Study Of Mathematical Normal Students’Problem Presentation Activity

The study of mathematical normal students’ problem presentation aims to enrich and develop the theory of problem presentation, provide a useful reference for carrying out mathematical normal students’ problem presentation activity. This paper puts forward the connotation of mathematical normal students’ problem presentation and the theoretical basis of the study through literature research, besides, the content of the problem presentation activity should include four aspects:"how to solve problems","source and background"," stretch and expand" and "teaching analysis". This paper puts forward three stages of mathematical normal students’ problem presentation activity:preparing to explain, oral explaining and commenting through questionnaire survey and organizing problem presentation competition. The main tasks of the stage of preparing to explain are to select problems, solve problems, research problems and write problem presentation articles. Oral explanation is the central link of the problem presentation activity. The five strategies of oral explanation are "be scientific and strict, clear and organized","be based on practice, penetrate theory","focus on the nature, trace to its source","look down, from a high viewpoint perspective","witty remarks, artistic embellishment". The two tasks of the commenting stage are the evaluation of the problem presentation skills and the discussion of mathematical problems. You can fill in "the assessment record form of the problem presentation skills" for qualitative and quantitative evaluation of the problem presentation skills. The way to develop problem presentation skills is to consolidate the knowledge base, pay attention to demonstration view, emphasize the individual practice, and promote self-reflection.
