Learning physics is difficult for high school students,and the teaching of solving physics exercises is the most important part.This paper investigates the current situation of physics-exercise teaching and students' ability to solve physics exercises through the questionnaire,in high schools of Jiutai City.The results show that students' ability to solve physics exercises still cannot reach a high standard,although teachers teach attentively and students study hard.To improve the efficiency of physics-exercise teaching and the students' ability to solve physics exercises,this paper employs problem-solving theory into solving physics exercises and proposes strategies for solving high-school physics problems which is based on problem-solving theory,after consulting the relevant literature on the problem-solving theory and the application of problem-solving theory in the teaching.By comparing the pre-experimental tests and post-experimental tests,students' problem-solving ability is found to be improved,which proves that the problem-solving strategies proposed in this paper are effective for improving the teaching efficiency.The combination of theory and practice shows that the strategies proposed in this paper is feasible.This paper conceives five parts:i.This chapter is introduction which states the current status of problem-solving theory,the significance of the topic and the research methods.ii.The method of the questionnaire is applied in this chapter which is to investigate the situation of physics exercise teaching in senior high school.Besides,the ability to solve physics problems of senior-high-school students is also investigated.iii.The strategies of solving the physics exercises is proposed in this chapter,which is based on the problem-solving theory.iv.The practice of solving physics exercises is demonstrated,which is based on the theory of problem-solving.v.The Conclusion. |
