Research On The Teaching Of Electrcity In Junior High School Based On Scientific Thinking

The electrical part of junior high school physics is an important part of junior high school physics,and it is the key point in the middle school entrance examination.It plays an important role in further learning physical knowledge for students,but it is also a difficulty in students' learning.Junior high school students generally reflect that it is dificult to learn electricity.On the basis of theoretical research,this paper combines electrical teaching with scientific thinking,and from the perspective of scientific thinking,puts forward teaching strategies of electrical teaching,hoping to improve students scientific thinking level in electrical teaching,and promote students' systematic learning of electrical science in improving scientific thinking level.This paper first introduces the background of the research on junior high school electricity based on scientific thinking,analyzes the research status of scientific thinking and electricity teaching at home and abroad,expounds the purpose and significance of this research,and introduces some educational theories on this basis.Secondly,it combs the main knowledge points of the electricity part of the junior high school physics textbook of Jiangsu Science Edition,and analyzes the characteristics of the electricity test in Suzhou senior high school in the past five years and the significance of the electricity in junior high school for the connection teaching of junior high school and senior high school.On this basis,it analyzes the close relationship between scientific thinking and the electricity teaching in junior high school.Then,I investigated 87 students in two classes of junior high school by questionnaire and analyze the homework of one class to understand the current situation of junior high school students' learning of physics and electricity and the problems of students' learning electricity.Then from the perspective of deepening the consciousness of model construction,cultivating the students' reasoning and demonstration ability and encouraging questioning and innovation,the corresponding teaching strategies are put forward.Combined with the corresponding theories and the proposed teaching strategies,the teaching design of the two sections of physics "rheostat" and "Application of Ohm's law"in junior high school is carried out.Finally,the research of this topic is summarized,the shortcomings of the research are reflected,and the further research of electricity in junior high school is prospected.
