The National College Entrance Examination,or Gaokao for short,is one of the country's most important exams.As a talent selection test,the college entrance examination owns high reliability,validity,differentiation and appropriate difficulty.Since the resumption of the college entrance examination in 1977,great changes have taken place in the time,subjects,forms,contents,methods of making questions and admission forms of the college entrance examination since 1977.The basic task of the new curriculum standard is to establish morality and cultivate people,develops quality-oriented education,and improves the comprehensive quality of our students in an all-round way.This achievement should be reflected not only in the school's study and life,but also in the college entrance examination,simultaneously examines the student's knowledge ability and the subject core quality.Under such educational background,the first-line teachers in senior high schools should take the college entrance examination proposition thought as a guide,master the proposition direction of the college entrance examination,pay attention to the students' comprehensive development,do a good job in reviewing for the college entrance examination,and improve the efficiency of review,enable the students to obtain the ideal result in the examination,enter their ideal universities.Guangxi is one of the last provinces to reform the college entrance examination.At present,its model is still "3 + 1",and applies the national examination paper,which plays animportant role in the analysis of national examination papers and the teaching of first-line teachers,science synthesis test paper includes physics,chemistry and biology,among which physics is a subject originated from life and used in daily life,which is closely related to the development of science,technology,society and economy.College entrance examination's physics mainly tests students' ability to understand,deduce,analyze and synthesize,use mathematics to deal with physical problems,and experiment.The test of experimental ability enables students to understand the purpose of experiments,the principles and methods of experiments,to control experimental conditions,to use instruments,to observe and analyze experimental phenomenon,to record and process experimental data,and to draw conclusions,to analyze and evaluate conclusions,identify problems,put forward problems,and make solutions;Enable students to use the physical theory,experimental methods and experimental instruments to deal with problems,including simple design experiments.There are two physics experiment questions in the science comprehensive examination papers in China.The electrical experiment is the focus of the experiment.However,according to statistical analysis of data,the question's scoring rate is not very high in the college entrance examination.Based on a large number of relevant literature,this paper makes an deep study of educational theory,taking the physical and electrical experiments in the National College Entrance Examination papers of the recent four years as the study objects,this thesis analyzes the characteristics and examination methods of the test questions of physical and electrical experiments in the four-year college entrance examination,and then analyzes the existing problems based on the scoring rate of the physics question in the recent four-year college entrance examination in Guangxi,interviews with senior high school physics teachers at different levels in Guangxi about the teaching methods of electrical experiments,analyze and sum up the experience and deficiency.In addition,this research also makes the questionnaire survey for the senior two and the senior three students in our school,analyzes their difficulty in reviewing this content.On this basis,combining with the reality of our school,this thesis puts forward some teaching strategies of electrical experiments,and puts it into practice in our school.Through the analysis of the physical and electrical experiment questions in the science comprehensive examination papers of physics from 2016 to 2019,we found that the questions have the following characteristics:(1)they come from teaching materials;(2)they have stablescores and reasonable settings;(3)they pay attention to innovation and have high flexibility.Based on the knowledge points of the electrical experiment in the college entrance examination in the past four years,this paper sets up a questionnaire to investigate and analyze the senior two and the senior three students' mastery of the contents of this section:(1)teachers should study the examination outline and curriculum standards carefully,study the textbooks and the test questions,and analyze the students' learning situation.(2)teaching according to the theory of classification of educational objectives.Helping the students review systematically with the help of textbooks and teaching-help books,enabling the students to grasp and remember the basic contents-going to the laboratory to do the experiment againcollege entrance examination real problem topic training-making questions by the teachers,aiming at the time-limited training,-the teachers guide the students to construct knowledge network-the teacher innovates the question,the students explain the questions,summarizeteachers analyze the examination result in time.(3)pay attention to the students' psychological dynamic,give timely psychological counseling to them,and encourage them. |
