| In August 2016,the Yancheng Education Bureau held a meeting to promote classroom teaching reform in primary and secondary schools in the city,and specifically proposed that the city-wide "Let learning and guide thinking" classroom teaching reform.The curriculum standards for compulsory education physics(2022 edition)call for the enhancement of Students’scientific literacy and their response to the challenges of the future society.This means that education implementers should face all students,give prominence to the students’ main status in the classroom,return the class time to the students,and let the students actively participate in the teaching activities,therefore,it is necessary to cultivate students’ ability of autonomous learning and autonomous inquiry,and to improve their scientific literacy.The teaching philosophy advocated by"Let learning and guide thinking" is also consistent with this.Let learning is to let students personally feel the process of learning,classroom teachers should give time,space and opportunity,let students learn,speak,do their own,their own thinking;Guide thinking is to fully activate students’ internal thinking motivation,teachers take the teaching goal as the guide,carefully design the teaching process,through classroom questions,group experiments,group discussions,classroom exercises and other forms of teaching activities,so as to guide,lead,stimulate students thinking of the classroom effect.Of course,this kind of classroom effect should not only be the mastery of knowledge,formulas,laws and skills,but also should include the cultivation of students’ physical basic literacy,physical values and physical learning habits.This study used the following research methods:literature research,questionnaire survey,case analysis.First of all,through the literature survey,the author summarized the research results of the domestic and foreign scholars on the teaching concept of "Let learning and guide thinking",and elaborated on the concept and essential characteristics of "Let learning and guide thinking",and clarified the theoretical basis of this study.In order to understand the current situation of physics classroom teaching in junior high school,this study through literature survey of the last five years of junior high school physics experiment,exercise,concept law class teaching situation,the main reasons behind the present situation are as follows:affected by the examination,the school’s teaching reform is not in place,the teachers’ teaching concept has not completely changed,and the students’ homework burden is heavy,etc..On this basis,according to the teaching concept of "Let learning and guide thinking",this paper puts forward the principles and strategies of physics classroom practice and carries out teaching practice,in order to provide some reference for physics classroom teaching in junior high school,we choose the second section of the fifth chapter "Speed" of the eighth grade physics volume of Suke edition as a typical practical analysis.The specific practical principles include:subjectivity,inspiration,living,development,simplicity,gradual progress,and the principle of teaching students according to their aptitude.Specific practical strategies include:elaborately designing pre class guidance to guide students to autonomous learning;Reasonably creating teaching situations to attract students’ active participation;Scientifically design classroom questions to guide students to think correctly;Timely promote group cooperation and cultivate students’ exploration ability;Encourage students to question and strengthen their thinking motivation;Attaching importance to the display of students’ achievements and stimulating students’ confidence in learning;Pay attention to testing and summarizing,and improve the knowledge framework of students;Emphasize diversified evaluation and lead students to self reflection.In order to study the practical effect of "Let learning and guide thinking" in junior high school physics classroom teaching,this study conducted a questionnaire survey on students.The questionnaire is divided into two parts:classroom situation and classroom effect.The classroom situation is mainly carried out around two indicators,namely,the situation of letting students learn and introducing ideas,in order to obtain the practical situation of "Let learning and guide thinking" in the physics classroom from the classroom activities fed back by students.The classroom activities include students’ reading,communication,thinking,observation,experimental operations,teacher-student interaction,group activities,and classroom exercises;Classroom effect mainly starts from two aspects:students’ learning desire and learning ability.Students’ learning desire is an important prerequisite to ensure classroom effect,and improving students’ learning ability is the ultimate goal of classroom teaching.Students’ learning ability mainly includes knowledge,operational skills,and thinking ability.Finally,the results of the questionnaire are analyzed.From the results of the questionnaire,the teaching concept of "Let learning and guide thinking" can greatly improve the efficiency of junior high school physics classroom teaching,which is very conducive to cultivating students’ physical literacy. |
