Based On The Characteristics Of The Physical And Electrical Experiment Questions Of The College Entrance Examination Research On Teaching Strategies

Physics is an experimental-based subject,and electrical experiment is the focus and difficulty in physics teaching.Not only the physics curriculum standards but also the College Entrance Examination has both laid special attention on the importance of students' experimental inquiry ability.However,in the traditional classroom experimental teaching,theoretical teaching is still more important than students' practice,which can not meet the standards and the requirements of the College Entrance Examination for students.Through the in-depth analysis of the curriculum standards and the physical and electrical experiment questions in the national college entrance examination since2007,this paper summarizes the specific requirements for students and teachers in the curriculum and the proposition characteristics and examination depth of the national college entrance examination,analyzes the students' current situation of electrical experiment learning through questionnaires,and finally puts forward the improvement strategy of high school physics electrical experiment teaching in combination with the current teaching status of the electrical experiment,so as to improve the students' experimental inquiry ability and achieve better teaching results.Through the review of literature,questionnaires,case studies and other methods,this paper studies the content and specific requirements of the electrical experiment part of the course and analyzes the content requirements and design significance of high school electrical experiment.Meanwhile,this paper studies the physics and electricity experiment questions of national college entrance examination since 2007 and the proposition characteristics of the national volume are analyzed from different aspects such as the proportion of scores,the content of the examination and the requirements of the ability.Finally,combined with the examination syllabus and the requirements of the college entrance examination questions,the questionnaire is designed,and the students' electrical experimental learning situation is investigated and studied from different aspects such as their interest,ability,learning style and expectation.Moreover,the frequency analysis of the results of the survey is carried out,which summarizes the problems existing in the current situation of students' electrical experimental learning.According to the analysis,it is found that the national college entrance examination electrical experiment questions tend to be more and more basic,innovative and designed.And at the same time,students' ability to choose experimental equipment,drawing(connecting)circuit diagram,data processing ability,error analysis ability and other aspects of the ability all have higher requirements,requiring students to master the basic principles and methods of the experiment,and can flexibly carry out migration applications.However,from the high school students physical electrical experiment learning questionnaire we find that the electrical experimental ability and practical ability of the whole high school students at present are weak.In view of the problems found in the questionnaire in the process of electrical experiment learning,the teaching improvement strategy is put forward in combination with the requirements of the curriculum and the characteristics of the electrical experiment questions of the college entrance examination,and finally,the proposed strategy is further studied in practice in the light of the existing teaching characteristics and conditions.Finally,effective strategies like the change of students' group experiment into a collaborative experiment,the change of demonstration experiment into a design experiment and setting up the students' innovation laboratory are concluded,which can fully mobilize the enthusiasm and creativity of students,exercise the students' experimental inquiry ability and hands-on ability,and in turn deepen their understanding of the experimental principles for flexible application.
