Research And Ractice On Improving Students' Modeling Ability In One Round Of Review Of Physics In Senior Three

General high school physics curriculum standards(2017 edition)deepens the goals of knowledge and skills,processes and methods,emotional attitudes and values in the physics curriculum goals into the core quality of physics,Namely,Physical concepts,Scientific thinking,Experimental exploration,Scientific attitude and responsibility.The ability to build physical model is an important index of scientific thinking ability.Especially in the third year physics review knowledge and exercises have covered more physical models,these physical models often combined with the specific situation appeared in the test.However,if students in the third year of high school do not pay attention to the cultivation of their ability to build physical models,it will lead to students falling into the tactics of test questions and low review efficiency.Through extensive reading of the literature,this thesis first carried out theoretical research on the cultivation of students' ability to build physical models in one round of review of physics in senior three.Secondly,the physical model examination in the physics part of the national comprehensive examination of science from 2015 to 2019 used by shandong province was analyzed from multiple dimensions,including the physical model examined,model type and construction ability level.Summary statistics of the physical model test and model type,and the requirement to test modeling ability of students has carried on the quantitative statistics,the subjects involved in the physical model is divided into three levels,and to statistics,the total score of each topic hierarchy for nearly five years the country a roll of a slight change of three layers model test score,but relatively stable,three layers model model score is roughly proportional to 3:5:2,pointed out the direction for the model teaching;Then,close to the university entrance exam to modeling ability requirement of weifang three mock exam questions,to teach students conducted a reflect the survey examination of physical model test,analysis of students per question 19,it is concluded that students at present for examination process model of every topic lower conclusion,then the students serves the lowest 25 titled,setting up specific modeling index,concluded that student modeling difficulty from abstracts the physical model of complex physical situation;Finally,the paper discusses the strategies to improve students' ability to build physical models in the review process of physics in senior three,that is,to guide students to summarize physical models and analyze the characteristics of typical physical models;Design step by step,guide students to experience the construction process of physical model;Using examples and variations to guide students to classify exercises;Adopt diversified teaching methods to enhance students' perceptual knowledge.And in what they teach senior class 4 round review teaching practice,teaching practice shows that model can help students establish a clear,features obvious physical model,can help students to classify the problem sets,students have a more accurate way,extracted from the complex physical environment the ability of physical models,are improved obviously.
