Teaching Strategies Of Connection Between Compulsory Chemistry And Optional Compulsory Courses In Senior High School Under The New Curriculum Reform

Chemistry Curriculum Standards for General High Schools(2017 Edition,2020Revision)(New Curriculum Standards)standard points out that the high school chemistry course is a basic education course connected with compulsory education chemistry or science courses,however,the current research on chemistry bridging teaching mainly focuses on junior and senior high schools or senior high schools and universities,and there are few studies on the bridging teaching between compulsory high school and selective compulsory high school.Therefore,based on the background of the new curriculum reform,this study takes the "Material Structure" module in "Compulsory Volume 1" and "Selective Compulsory 2 Structure and Properties of Matter" as an example to study the cohesive teaching in high school,in order to "material structure" module as an example of bridging study high school teaching,so as to provide a variety of teaching strategies for teachers,help students pass the basic education stage smoothly,lay a solid foundation for the higher education stage.,Studying chemistry,and willing to contribute to the development of chemistry.This study mainly analyzes the content requirements and academic quality requirements of the module of "material structure" in the curriculum standard,as well as the way of presentation and cohesion in the teaching material.It finds that the knowledge of the module of "material structure" in high school is progressive and tends to be theoretical.Combined with the results of questionnaire survey and interview,the corresponding cohesive teaching strategies and principles are put forward,such as learning plan guidance,constructing mind map,following the requirements of curriculum standard,rational use of teaching materials and modern information technology auxiliary teaching tools to assist teaching.Then combined with the fourth chapter "Atomic Structure and Periodic Table of Elements" in the "Compulsory Volume 1",the teaching and research are carried out,and the cohesive teaching is carried out around the new knowledge in the teaching process,and the student is the leader,with the help of mind maps,modern information technology and other teaching tools,combined with real situational materials and various evaluation methods to carry out cohesive teaching,so that students’ knowledge is systematized.Finally,through the analysis of classroom exercises,homework and examination papers to judge the operability of teaching and strategy.The research shows that the knowledge in high school is interlaced and linked together,compulsory is the basis of selective compulsory,and selective compulsory is the expansion and improvement of compulsory.Therefore,in the teaching process,teachers should make a good connection between compulsory and selective compulsory courses based on the course standard and textbooks,and guide students to learn to independently integrate knowledge,build knowledge framework and form a certain knowledge network.
