Research On The Application Of Self-made Teaching Aids In Physics Teaching In Senior High School

"General High School Physics Curriculum Standard" pointed out that experiments as an important part of physics teaching is an important way to cultivate and develop students' physics core literacy,and encourage teachers to actively create conditions,and be good at using daily necessities to improve or develop experiments.In physics teaching,self-made teaching aids can often rely on its "lower cost,intuitive image,flexible and simple" and other characteristics,to play its unique advantage,helps alleviate problems such as insufficient or missing laboratory equipment(especially in rural schools),make abstract physical concepts or physical laws concrete,improve students' hands-on ability and experimental operation level;help to stimulate students' interest in learning physics,and gradually help students build relationships between physical and life.It is of great theoretical and practical significance to improve physics teaching effect and students' all-round development.On the basis of studying and sorting out relevant literature,based on the questionnaire survey and statistical analysis,this paper made a questionnaire survey on the situation of "high school physics experiment and self-made teaching aids" among teachers and students of a provincial and municipal model high school in Guizhou province.Through the analysis of the questionnaire,we can find that the teachers and students support experiments,but during the process of physical experiments,there is indeed the lack of experimental equipment or equipment old,the experimental effect is not ideal,and the data is not accurate.Therefore,teachers and students believe that they can use self-made teaching aids to assist physics teaching,and believe that this can improve teaching effects,have a positive role in the cultivation of physics core literacy,and teachers and students are willing to actively participate in relevant lectures or training.But they usually have very few opportunities to participate.Based on the reading and the discussion with experienced frontline teachers and mentors,combined with my thinking,the production strategy of high school physics self-made teaching aids is put forward,and the recommended methods are mainly: principle simulation method,imitation method,transformation method and combination method.The main principles that should be taken into account in production are: purpose and science,inspiration and innovation,intuitiveness and flexibility,safety and economy;the basic steps mainly:(1)determine the production direction,clear the purposes of production;(2)design a preliminary production plan;(3)determine and collect relevant materials;(4)refine the production plan of self-made teaching aid,and do active operation;(5)the debugging and modification of self-made teaching aids;(6)the final setting of self-made teaching aids.Based on the related self-made principles and steps,creating teaching aids in combination with content such as "exploring the law of isothermal change of gas","exploring the law of isovolumetric change of gas","exploring the law of isobaric change of gas" and so on.Combined with self-made teaching aids,the teaching case is designed.Self-made teaching aids is flexibly applied to high school physics teaching,and the student's scientific exploration ability and physical score are examined.By the comparison and analysis of two groups: "experimental classes,control class" in Class A and Class B,we can find that the difference of pre-test scores between two classes of Class A class is not significant.the difference of pre-test scores between two classes of Class B class is also not significant.Among them,the P value of the pretest scores of 2 classes of Class A was 0.864,and the P value of the pre-test scores of 2 classes of Class B was 0.673;the P value of the pre-test scientific inquiry ability score of 2 classes of Class A is 0.680,and the P value of the pre-test scientific inquiry ability score of 2 classes of Class B is 0.562.At the post-test,either in Class A or B,the average score of the experimental class is higher than the control class,and the difference in the post-test scores is significant.Therefore,combined with students' interviews,according to the quantitative analysis of the previous two dimensions,it is known that using self-made teaching aids to assist physics teaching can improve students' participation in experiments,stimulate students' interest in learning physics,improve students' physical score,cultivate and develop students' scientific research ability.
