Research On The Integration Of Thermal Dynamics Teaching Content In Junior Middle School

In the process of cultivating and developing students' subject core quality,thermal science,which plays an important role in physics teaching in junior middle school,has been paid more and more attention.Therefore,based on the comparison of the thermal part of the physics textbooks of China and the United States,calorifics teaching contents of the integration of research,help students to form a system of thermal knowledge concept,train students' practice in thermal capacity,higher in the field of thermal branch or cross have more interest and exploration,excavate the potential of students' thermal innovation,it is very necessary.In this paper,we conduct a research on the integration of junior middle school thermal teaching and learning contents.First of all,we investigated the research status of junior high school heat at home and abroad,and introduced the theory of education.In junior high school physics teaching,we noticed that the distribution of thermal knowledge points in physics teaching in Jiangsu province is scattered,which makes it difficult for students to form a systematic thermal knowledge system.The vague concept of thermal knowledge is not conducive to the connection of thermal knowledge points in junior and senior high schools.We designed a questionnaire and analyzed the students' learning status.Secondly,we integrate the teaching content:one is from the students the classroom perception and the teaching feedback of the examination method are integrated;The second is to combine the thermal part of the American explorer textbook with the Physics textbook of the Suke edition and comprehensively select the teaching integration that is conducive to students' thermal learning.Three is on the basis of existing thermal teaching in Jiangsu,with the thermal part of junior high school of knowledge,including the teaching material's thermal content arrangement,the time distribution of knowledge points,the characteristics of the teaching material directory,the actual life of the thermal experiment and books of classical thermodynamics,the combination of the traditional classroom teaching form to take the student as the main body thermal teaching team to explore the methods of integration.Finally,we integrate teaching practice and evaluation.Taking class 2 of Jingkou Middle School in Zhenjiang city,Jiangsu Province(with slightly weak student foundation)and Class 8 of Grade 2(with relatively good student foundation)as practical objects,we take into account the traditional classroom teaching of thermal science and the classroom of club activities using science and technology associations,and carry out two kinds of classroom teaching practices for Chinese and American thermal science students.We compared and analyzed the differences and similarities of thermal teaching in Chinese and American thermal teaching materials from the perspective of classroom teaching methods and thermal knowledge examination methods.We also extracted integrated measures that are conducive to students' learning of thermal science through questionnaires and student interviews.It includes adjusting the order of large chapters in thermal teaching;Expand the content of small chapters and teaching experiments;Select the appropriate way of homework examination and student experiment;To improve the arrangement of illustrations and colour matching.Then,we use the form of community activities to practice the integrated thermal teaching mode,use the integrated teaching materials for thermal teaching practice,and compare the feedback results from the students.Our teaching practice shows that students have made remarkable progress in the whole systematic cognition of thermal science,the synthesis of thermal knowledge and thermal experiment.In addition,in the feedback of knowledge examination related to thermal science,students' overall thermal level has been improved,their basic understanding of thermal science has been more thorough and comprehensive,and their breadth of thermal knowledge has also been significantly improved.
