Research On The Application Of Problem Guided Teaching Method In Physics Teaching In Senior High School

Facing the challenges of international competition in the information age and talent training in the 21 st century,there are new requirements on how to have the necessary character and key ability for students' lifelong development.Focusing on the integration and development of core literacy has become the main body of curriculum reform and teaching improvement.How to improve students' core quality of physics has also become the focus of physics teaching.Problems are the driving force of thinking and the basis of innovation,and the generation of thinking is caused by problems.Thinking without problems is simple,and students' learning is passive.After the problem is put forward,it often involves the solution of the problem.How to solve the problem and cultivate students' thinking ability has become the focus of physics classroom.Based on the above reasons,it is particularly important to study how to improve students' core quality of physics through physics teaching.This paper mainly focuses on how to improve students' core quality of physics by studying the problem-based teaching method.By carefully designing the problem chain,students can actively think,participate in cooperation and exchange,and teachers can timely guide and help students solve problems,which fully reflects the teaching concept of students as the main body and teachers as the supplement.Based on the research,the teaching design is prepared,which is expected to be used in front-line teaching,which is helpful to help students solve problems and improve their quality.The main work of this study:(1)by consulting relevant literature,books and sorting out materials,this paper expounds the research status of "Problem-based Teaching","problem-guided teaching",problem solving,problem-guided cooperative and inquiry teaching at home and abroad.(2)Define the related concepts of "core literacy",problem-based teaching,constructivism and so on.(3)In the form of questionnaire,this paper designs,distributes,collects,arranges and analyzes the questionnaire,investigates and studies the current situation of the application of problem-based teaching method in physics in middle school,and analyzes the problems and causes.(4)In the analysis of the key research points of the application of problem-based teaching method in senior high school physics,this paper expounds how to create problem situations and the matters needing attention in creating problem situations.Based on the above analysis,this paper summarizes how to put forward effective problems,the guiding role of teachers and the basic form of problem guidance.(5)Based on problem-based teaching,taking "polarized laser of light" and "experiment: measurement of battery electromotive force and internal resistance" as examples,two teaching designs are designed in order to provide reference and reference for front-line teachers to effectively cultivate students' scientific thinking ability.(6)This paper reviews and summarizes the problem-based teaching method and prospects the teaching method.
