Research On Junior High School Physics Teaching Integrating Science And Technology Application

In the context of the continuous development of science and technology,the"Compulsory Education Physics Curriculum Standard(2011 Edition)" proposes that the content of junior high school physics curriculum should focus on the connection with students’ life,modern society and technological development,and pay attention to the new progress of science and technology.As the current emerging scientific and technological knowledge,knowledge of nanoscience and technology can reflect the new progress of science and technology and play a positive role in the cultivation of scientific and technological innovation talents.The industry of nanoscience and technology has grown rapidly in the past ten years.The country has built various industrial parks in many places,focusing on the development of the industry of nanoscience and technology;it has taken the lead in building a number of national bases of nanoscience and technology.The development of these industrial bases of nanoscience and technology provides all-round resources for nanoscience and technology education.Therefore,inserting the knowledge of nanoscience and technology into junior high school physics teaching is not only the advocacy of curriculum standards,but also the development need of technology.This research has theoretical and practical research significance.This paper uses the method of literature analysis,questionnaire survey,interview and content analysis to carry out the teaching research of nanoscience and technology knowledge insertion in physics for junior middle school.First of all,through the arrangement of the"Physics Curriculum Standards for Compulsory Education(2011 Edition)",junior high school physics textbooks of Phoenix Science Press edition,books and literatures related to nanoscience and technology,the subjects of junior high school physics courses and the basic concepts of nanoscience and technology are given.Based on this,the knowledge of nanoscience and technology that is already in the textbooks and that can be inserted into junior high school physics teaching is systematically sorted out.Among them,there are 39 items of content of knowledge of nanoscience and technology insertable in junior high school physics teaching.Secondly,the study status of students about nanoscience and technology knowledge insertion in physics for junior middle school is investigated.The survey results show that junior school students have a strong interest in the study of nanoscience and technology knowledge.Thirdly,through the interviews with junior high school physics teachers and college teachers,the scientificity and feasibility of the nanoscience and technology insertion content sorted out in this study are analyzed.The interview results show that 36(39 in total)items of content of knowledge of nanoscience and technology that can be inserted into junior high school physics teaching in this study are scientific and effective,and are recognized by junior high school physics teachers and college teachers.Appropriate adjustments are made to the remaining 3 items of content of knowledge of nanoscience and technology that are not suitable for inserting into the physics teaching of junior middle school.The results of the student questionnaire survey and teacher interviews show that the current situation of junior high school physics teaching is conducive to the insertion of knowledge of nanoscience and technology in junior high school physics,but there are still many problems:teachers and students do not pay enough attention,the content of teaching materials is not novel,teachers have less knowledge of nanoscience and technology reserves,the class hours are tight and so on.Finally,based on the analysis of the results of the student questionnaire survey and teacher interviews,five teaching strategies are proposed,namely:organizing teacher exchange and training,daily classroom teaching insertion,setting up relevant school-based courses,combining exercises to insert nanoscience and technology knowledge,comprehensive practical activities.And corresponding teaching cases are designed,aiming to provide the majority of educators with reference to the insertion of nanoscience and technology knowledge into junior middle school physics teaching.
