Difficult Analysis And Strategy Research Of Circuit Problem Solving Of Senior High School Students

Middle school students always have the problem of ‘understanding' but ‘can't do'when learning physics.This phenomenon is particularly prominent in the study of circuit.What is the reason why students can't solve problems? Based on the research of problem-solving process in information processing psychology,this paper attempts to study and analyze the causes of this phenomenon,and puts forward effective solutions and teaching strategies.This study mainly adopts the methods of literature research,protocol analysis,interview and case analysis.Firstly,through the sorting and analysis of senior two students' circuit chapter homework and test papers and the interview with four frontline teachers,the author concludes the types and characteristics of difficult problems in senior high school circuit chapters.Then,this paper uses the protocol analysis method to study the obstacles of 24 students with different grades in solving circuit problems,and analyzes the reasons by using the theories of information processing psychology and cognitive psychology,and analyzes the differences of students' behavior.The results show that students with problem-solving difficulties have some defects in problem representation,basic knowledge and skill reserve,metacognitive monitoring and so on,and show great differences from students with good problem-solving.Then,interview and study the teaching strategies adopted by front-line teachers,and summarize their shortcomings.Finally,combined with the research results of pedagogy and psychology,this paper puts forward teaching strategies that can help students overcome the obstacles of circuit problem-solving and improve their problemsolving ability,and designs teaching cases to analyze its rationality and effectiveness.
