The Study On Mathematical Problem Presentation Activity Of Senior High School Students

The study on mathematical problem presentation of senior high school students aims to enrich and develop the theory of problem presentation, providing a useful reference for carrying out mathematical problem presentation activity. The connotation and theoretical basis of the study are summaried through literature research in the paper, besides, the content of the problem presentation include nine aspects, such as "source and meaning of problem","knowledge network". The author sum up the four stages of problem presentation through interview and survey study, including planning and preparation, demonstration and guidance, student problem presentation, rethinking and summary. The main task of planning and preparation are to make sure grade, select problems, and write problem presentation articles. The two aspects of demonstration and guidance stage are to publicize the problem presentation activity and try to present problems. Student problem presentation is the central link of the activity, guiding students experience mathematical communication process of solving problems autonomously, researching problems in team, writing problem presentation articles, representatives’ problem presentation, teachers and students’ evaluation of problem, reflecting on problems. The stage of reflection is conclusing experience to improve deficiency through interview and analysis of the problem presentation material.This paper come to think from both teacher and student through the analysis of action research.Teacher is the organizer, leader and partner of the problem presentation activity. The way to develop problem presentation ability is to build atmosphere, strengthen language training, lead the cognitive orientation, show insight in practice, and rnalize acquisition skills.
