A Study On The Designation And Application Of Low-cost Physics Experiments In Junior High School

China is undergoing a transition from "Made in China" to "Created in China".The transformation of society will inevitably put new demands on education.Cultivating innovative talents is the main goal of current education in China.With the implementation of quality-oriented education,cultivating the sense of innovation and improving their practical ability have been put on the agenda.Low-cost physics experiments mainly use waste materials in life as materials.Therefore,people often called it as "non-influenced" experiments and often ignore their great wisdom.In addition,the low-cost physics experiment teaching plays an irreplaceable role in cultivating students' innovative consciousness and improving their practical ability.This dissertation is mainly based on previous research,combined with personal expertise,improved and innovated some low-cost physics experiments.The study is mainly developed from five aspects:(1)The introduction part analyzes and summarizes the background and current status of the current low-cost physics experiment,expounds the purpose and significance of the research;(2)The concept and the basic part of the research define the concept of low-cost physics experiments and self-made teaching aids and unconventional physics experiments,and based on the characteristics of low-cost physics experiments,some of its concepts are inherently extended.In addition,the design principles of low-cost physics experiments were also proposed;(3)The source part of the material mainly based on the author's actual design experience,combined with examples to put forward two aspects of the sources of low-cost physics experiments,namely the source of inspiration materials and Sources of material materials;(4)The practical case analysis mainly proposes five model cases and more than ten low-cost physics experiment teaching cases based on the low-cost physics experiments frequently used in junior high school physics teaching activities.(5)At the end of the dissertation,the research is summarized and reflected.This study proposes the source of design inspiration and analysis of design ideas for low-cost physics experiments,analyzes how to design low-cost physics experiment teaching models based on students' psychological characteristics and zone of proximal development,and effectively demonstrates the application of low-cost physics experiment teaching modes.This will provide some experience for junior high school physics teachers to design and apply low-cost physics experiments in their daily teaching process.
