The Research Of Using Life Experiment To Stimulate The Interest Of Physics Study In Junior High School

Based on life education theory,constructivism theory,pragmatism theory,middle school students' core accomplishment and compulsory education physics curriculum standard,this thesis discusses the main principles to be followed to stimulate the interest in biology learning in junior high school by using life experiment,namely,scientific principle,life principle,interest principle,simplicity principle and safety principle.Passing three before and after class In order to give full play to the role of life experiment in junior high school physics teaching,the questionnaire of "the present situation of junior high school physics life experiment teaching" was designed,and the investigation was carried out in Linxiang Nie City Middle School and Hony Xinhua Middle School.This thesis preliminarily understands the present situation of physics experiment teaching in junior high school,recognizes the shortcomings and drawbacks of physics experiment teaching at present,and the students' cognition of life experiment.It further confirms the feasibility and necessity of carrying out small experiments in physical life.The innovative work of this thesis is to apply life experiment to physics teaching,to combine book knowledge with life experience effectively,and to take the physics textbook of junior high school as the carrier,five concrete experimental teaching design schemes are given.We also apply these fragment designs to specific teaching practices and achieve good teaching results.They are:The teaching design of friction power.Among them,we designed "plastic spoon to attract foam "," plastic ruler to attract bubble "," balloon to attract small water column "," after friction drink bottle to attract foam" four students experience activities,so that students personally feel the process of friction to start electricity,effectively stimulate students' interest in learning physics.The teaching design of exploring sound is produced by the vibration of objects.We successfully attract students' attention through "salt dance ",and then lead students to complete " self-made whistle "," self-made trumpet " two simple scientific small production,to cultivate their hands-on ability.The teaching design of vaporization and liquefaction.We used alcohol and disposable gloves in daily life to carry out "alcohol vaporization" experiments.The experimental phenomenon is unexpected to the students,which not only enlivens the classroom teaching atmosphere,but also arouses the students' enthusiasm for learning.The teaching design of exploring the effect of pressure.We designed two student experience activities,and skillfully applied self-made teaching aids to classroom teaching in order to guide students to use control variables to explore the factors that affect the effect of stress.Cultivate students' rigorous scientific attitude."Demonstrate eyelet imaging" teaching design.In order to help students solve the difficulties encountered in exercises and overturn the wrong pre-concept,we guided students to use disposable paper cups for group experiments in teaching.In the process of establishing new knowledge,we cultivate students' ability of independent inquiry and cooperation and communication.In addition,we designed a series of low-cost,simple and interesting experiments in physical life.Such as the use of balloons,cardboard,disposable paper cups,beverage bottles and other common life items to make students' favorite "backwash balloon car "," simple balance ",using boards and plastic toy syringes to make "explore the factors affecting the effect of pressure " physical teaching aids.Finally,on the basis of theoretical collection and practical experience,we summarize the development of small experiments in physical life.Specific include:the use of daily necessities,the use of food resources,recycling waste goods,the development and use of toys and other aspects.
