The Application Of Physical Model In The Teaching Of Physical Mechanics In Senior High School

As one of the most important subjects in basic education,physics teaching in senior high school has a foundational function on the national training of science and engineering talents,and provides a strong guarantee for the economy take-off and great rejuvenation of our country.As an old Chinese saying goes: " If you want to do a good job,you must first sharpen your tools." physical models,one of the key directions of curriculum reform,are the sharp weapons in high school physics teaching.French scholar Ari’s point: " The basic activity of science is to explore and develop models." has also shown the same wisdom.Going through our physics textbook,we can find physical models running through every part of it.A physical model refers to a physics thinking that simplifies and solves some practical problems on the basis of physics.Through the effective application of these models in teaching,the teacher can intuitively show the core content of the physics phenomenon to the students,ignore the secondary factors and keep the nature of physics phenomenon as much as possible,thus to establish the students’ effective understanding of physics concept and formula to get a better classroom teaching effect.And cultivate students’ physics concept,scientific thinking and other core qualities.However,in the western region of Henan Province,due to the pressure of entering a higher school,many high school physics teachers still pursue the improvement of students’ ability to do questions with the "cramming" teaching method.However,there is not enough attention to the improvement of students’ scientific thinking,and the application of modeling teaching is still very little.Based on this,and considering that mechanics is the most important part of physics,this paper takes the mechanics part as an example to study the practical problems and application schemes of high school physics model in mechanics teaching,aiming to find a new and efficient application way in teaching,and put forward new thinking for the teaching application of local high school physics model.This paper is mainly divided into the following parts: The first chapter is the introduction part.This part introduces in detail the history and status of physical model teaching application research at home and abroad,and analyzes the main work and practical significance of the existing literature.And introduce the research significance and content of this paper.The second chapter defines the concept of the physical model,and expounds the theoretical basis of the educational psychology involved in this paper.It also analyzes and discusses the properties and characteristics of the physical model and the process of model construction.The third chapter analyzes the application status of the existing mechanical model from three aspects: classification method,situational application and college entrance examination situation.The third section focuses on the classification and summary of the mechanical problems in volumes I and B used in Henan province in previous years,and analyzes the frequency and emphasis of each mechanical model.Finally,take a specific typical topic as an example to explore the way of investigate the model.The fourth chapter is based on the research results of the third chapter,based on the investigation ideas and teaching practice of the college entrance examination,and innovates the six physical models of the key investigation of the college entrance examination in recent years.On the basis of more conducive to students’ mastery,the physical model is innovatively named and writes the memory optimization of the formula.According to the optimized content,some of the key models are applied to classroom teaching and exercises construction,and the actual effect is studied in practice.Chapter 5 summarizes and reviews the research results of the full text,analyzes the gains and losses,and sorts out the ideas.The problems and deficiencies in the study were analyzed.
