Practice Of Infiltrating The Cultivation Of Students' Logical Thinking Ability In Physics Teaching In Junior Middle School

In recent years,with the continuous deepening of teaching reform in my country,the cultivation of "innovative" thinking has become the foothold of today's educational development.And students have strong logical thinking ability is the basic condition for cultivating their innovative thinking.In recent years,the OBE concept has been applied to different teaching fields by the majority of front-line educators due to its own orientation,fairness,synergy and challenge.This paper investigates the current situation of logical thinking of junior high school students,and takes the second-year junior high school students taught as the research object.The integration of the OBE concept and the problem teaching model,that is,the problem teaching model based on the OBE concept,is applied to the junior high school physics classroom teaching,and whether it is helpful to cultivate students' logical thinking ability is tested in teaching practice.The research content of this paper is roughly divided into the following Several parts:The first part: theoretical research,expounds the concepts of OBE teaching theory and problem teaching theory,and sorts out domestic and foreign research literatures on cultivating students' logical thinking ability,and clarifies the research background of this topic.At the same time,it puts forward the importance of OBE concept in cultivating students' logical thinking,and discusses the theoretical and practical significance of this research,and organizes the research methods.After completing the literature review,a series of concepts involved in this paper,such as problem teaching method,OBE teaching,logical thinking,etc.,are conceptually defined,and the theoretical support of this paper is deepened.The second part: In order to understand the logical thinking situation of junior high school students,a questionnaire about the current situation of junior high school students' logical thinking was compiled.The survey results were explored.Afterwards,an interview survey was conducted,and the survey objects included some teachers and students.The results of the survey and interview show that the current situation of students' logical thinking ability in various dimensions is not optimistic.The main influencing factors are: from the perspective of students,their ability to distinguish and clarify physical concepts,and their ability to establish and divide physical concepts.The ability,the ability to analyze and judge the sufficiency and sufficiency of physical laws,the ability to control the excessive jumping of thinking,and the ability to restrain the moderate extension of thinking are insufficient;from the perspective of teachers,they do not pay enough attention to cultivating students' logical thinking ability.Therefore,the author believes that in order to cultivate students' logical thinking ability,it is necessary to start with innovative teaching methods,which has also become an urgent requirement for students' personal development.To sum up,the author proposes a problem-based teaching model based on the OBE concept,and compares it with the traditional teaching model.On the one hand,it discusses the necessity of cultivating students' logical thinking based on the problem-based teaching mode under the OBE concept.On the other hand,it discusses the application strategy of cultivating students' logical thinking in the process of teaching practice based on the concept of OBE.The third part: analyzes the selection basis of the two classes in this teaching,discusses the results of the questionnaire survey,conducts the test,and takes the test results as the pre-test results.The results confirmed that there was no significant difference in the logical thinking ability of the students in the experimental class and the control class.Based on this,in order to demonstrate the effect of the problem-based teaching mode based on the OBE concept on cultivating students' logical thinking,the experimental class is based on the OBE concept and problem-based teaching to carry out daily teaching work,while the control class adopts the conventional teaching mode.The fourth part: After one semester of teaching practice,the two classes were re-analyzed the situation of question and answer mapping and the analysis of the questionnaire survey results.The results show that there are significant differences in the status of logical thinking ability of students in the two classes,and the logical thinking ability of students in the experimental class has been significantly improved.It shows that the problem-based teaching mode based on the OBE concept is helpful to cultivate students' logical thinking ability.In a word,through investigation and practice,it is found that through the problem teaching mode based on the OBE concept,under the guidance of the interlocking problems designed by teachers,the students' logical thinking ability has been comprehensively cultivated.Students' logical thinking ability to distinguish and construct concepts,logical thinking ability to analyze and judge laws,and control thinking ability have been significantly improved.The author hopes that the research in this paper can provide some theoretical references for the cultivation of students' logical thinking in physics teaching.
