The Grasp Of The Teaching Timing In High School Students' Advanced Chemistry Learning

Advanced Learning is the process of thought transition over time,and the smooth transition of thinking involves the Timing of Teaching.Research on Aadvanced Learning and Teaching Timing is beneficial for teachers to evaluate the teaching effect accurately,to establish the core concept knowledge system and to improve the teaching efficiency.The writer selected the "redox reaction" as the research object,because it is the leading part of the high school chemistry.The writer sorts out the teaching materials according to the contents and requirements of 2017 National New Curriculum College Entrance Examination Outline of Chemistry,and related concepts and theories of the Junior Chemistry textbooks and the Senior Chemistry Compulsory 1,2 and Elective 3,4,5.After reading the related content Junior Middle School Chemistry Curriculum Standard and Senior High School Chemistry Curriculum Standard,the writer uses the concept map combing with the researches on the core concept to extract 4 core concepts:the oxidation and the reduction,the oxidability and the reducibility,the reaction equation of redox reaction,and the essence of redox reaction.Then combining the results of the research on the wrong understanding of redox reaction field of senior high school students,the writer confirms the teaching design of the advanced learning timing.The writer uses the Advanced Learning of the redox reaction equation writing and the teaching timing as empirical research,and the traditional method and the teaching plan of advanced learning and teaching timing to teach in the control class and the experimental class respectively.Compared with the test results before and after the experiment,it is concluded that the grasp of teaching timing in oxidation-reduction reaction can promote both teachers and students.This study combines the Advanced Learning,Teaching Timing and high school chemistry to construct the knowledge system of redox reaction,and puts forward the teaching design of core concept learning and Teaching Ttiming,so as to provide teaching reference for other teachers.
