| Junior high school physics is very important for students’ understanding of physical phenomena and laws of physics,and plays an important role in the cultivation of students’ various thinking abilities.It can help students use scientific abilities to solve actual problems and promote their growth.However,due to the influence of teaching methods and students’ own factors,students will encounter many difficulties in the process of junior high school physics learning.In the actual teaching,I also deeply feel that the students in the electrics sector are very difficult to learn,and the learning effect is not satisfied.Based on this background,in order to improve the quality of teaching in future teaching and help students reduce the difficulties in learning electricity,the reasons for the difficulties in learning the knowledge of physics and electricity in junior high schools are studied,and solutions are found.I hope to provide colleagues with new ideas and methods to carry out teaching work more efficiently.This article uses statistical method,interview method,literature review method and questionnaire survey method to conduct two sub-studies.Study one.The first step is to sort out the electrical content in the "Curriculum Standards".The degree of mastery of different knowledge points is not the same,and sort out the electrical content corresponding to the "understanding" and "understanding" with a higher degree of mastery.The second step,the textbook is As a blueprint for students’ learning,the next step is to sort out the contents of the electrics part of the PEP physics textbook in more detail: sort out the distribution of the content of electrics,sort out the knowledge structure of each chapter,in view of the previous sorting out of the "Curriculum Standards",focus on Content The two lessons of Ohm’s Law and Joule’s Law are analyzed one by one.The third step is to grasp the direction of the survey from the Chongqing high school entrance examination questions,and more accurately locate the learning difficulties of students.The learning difficulties under these main contents are combed theoretically to determine the general content of electrical learning difficulties,and then the questionnaire is used to actually investigate the learning difficulties of students and the troubles of teachers in teaching.Study two.According to the main knowledge points of learning difficulties and the objective conditions of learning difficulties selected in the first section,actual questionnaire surveys are carried out on students and teachers.The survey is mainly divided into two parts,one is to investigate the current learning situation of students,and the other is to investigate the teaching situation of teachers.This research shows that: in the process of combing the "Curriculum Standards",it is found that the target requirements are high standards: Ohm’s law,electric work and electric power,Joule’s law,among which electric work and electric power also involve real life applications;analysis of textbooks The major and difficult points are concentrated on "17.2Ohm’s Law" and "18.2 Electric Power";the analysis of the examination questions,the investigation hotspots and difficulties are mainly concentrated on the understanding and calculation of Ohm’s Law and electric power;the main difficulties for junior high school students in studying electricity are: Ohm Law,electric power,Joule’s law.Finally,this article proposes two types of strategies based on the previous research.The first category is general strategies for electrical learning,and the second category is specific strategies for electrical difficulties... |
