Practical Research On "Question Chain" Teaching Mode In Senior High School Physics Classroom

It is advocated to guide students to form scientific thinking habits and enhance their ability to explore and solve practical problems through diversified teaching methods in Physics Curriculum Standards for Ordinary Senior High Schools(2017 Edition,Revised in 2020).Classroom questioning is one of the important teaching methods.However,there are still some phenomena in class questioning,such as the difficulty of the question is not suitable for students,the design of the question is not situational,the discussion time of students is out of control,and the teaching progress is slowed down,which cannot give full play to the advantages of class questioning.Students still think physics is too difficult and have no interest in learning physics.In view of these phenomena,problem chain teaching is a good solution.However,in teaching practice,if the questions raised are lack of pertinence and integration,and the logic is inconsistent,it will hinder the development of students’ subject core literacy and the improvement of classroom efficiency.Therefore,how to design the "problem chain" teaching model is a problem worthy of our study.Firstly,based on a large amount of literature review,the research background,research purpose and significance,research status at home and abroad as well as research content and methods are introduced,the related concepts such as problem chain are defined,and the theoretical basis of the theory of proximal development zone and problem teaching theory are listed in this dissertation.Secondly,the pthysies ciassroom of the grade one in the practice school is observed through classroom observation,and the results are statistically and analyzed.According to the results of analysis,the design idea and teaching process of "question chain" teaching mode are put forward.Two subjects are selected to design teaching cases,and one of them is selected to carry out practical research in the practice school.Finally,the summary,and prospects are shown,and the teaching suggestions for the existing shortcomings are given.
