Study An Training Strategy Of Junior Middle School Students' View Of Chemical Change

The view of chemical change is one of the important concepts in middle school chemistry.The formation of junior middle school students' view of chemical change not only helps students to better grasp chemical knowledge,but also helps students to understand that chemistry is a science that studies the composition,structure,properties and changing law of substances.It also helps student to establish the concept of subject and lays a solid foundation for students' lifelong development.The content of the paper is mainly composed of six parts,the main contents are as follows:1.The introduction introduces the proposition of the problem,the theoretical and practical significance of cultivating students' view of chemical change and the main contents of the research.2.To sort out the current research situation of chemical basic concepts and the reasons that affect the formation of chemical basic concepts,to study the content of chemical change concepts,to investigate the current situation of chemical change concepts,and to summarize the strategic research results of cultivating middle school students' chemical change concepts.3.A questionnaire survey was conducted among all the junior three students of the secondary school affiliated to Anshan Normal University on the mastery of students' view of change,followed by interviews with four front-line junior middle school chemistry teachers in the secondary school affiliated to Anshan Normal University to further understand the mastery of the current junior middle school students' view of change in chemistry.4.After analyzing the students' mastery of the view of chemical change,four cultivation strategies of the view of chemical change in junior middle school students are put forward.5.Designing the teaching implementation of Chemistry Change View in junior high school chemistry textbook of PEP combined with relevant strategies.6.Teaching suggestions,reflections and conclusions.Through the analysis of the results of questionnaires and interviews,understands that junior middle school students have not fully grasped the content of chemical change concept that should be grasped in the junior middle school stage.In view of the content of chemicalchange concept that junior middle school students should grasp and the law of students' cognitive development summarized by predecessors,the author puts forward four training strategies of junior middle school students' chemical change concept and design the teaching implementation and suggestions to cultivate junior middle school students' view of chemical change,hoping to provide some reference for the majority of junior middle school chemistry teachers.
