The Exploration Of High School Chemistry Variable Teaching To Promote The Development Of Students' Analogical Transfer Ability

Under the background of the new college entrance examination reform,the new evaluation concept in "China college Entrance Examination Evaluation System" emphasizes the memory,storage,understanding and transfer of examination knowledge.In practical teaching,it is found that analogical transfer plays a very key role in the process of problem solving,while variable teaching can guide students to master the essential attributes through external characteristics and use accumulated experience to deal with multiple changes.Variable teaching in high school chemistry has a great influence on the development of analogical transfer ability.Through literature reading,combing and integrating relevant theories,this study analyzes and discusses the relationship between variable teaching and the development of analogical transfer ability.Secondly,according to the characteristics of chemistry,a variable teaching model is constructed to promote the development of students' analogical transfer ability.Then,the variable teaching design is carried out around the related teaching contents of compulsory Chemistry course 1 of human Education Edition,and three specific examples of chemistry basic concept course,experiment course and exercise course are selected to present and explain.Finally,through the teaching experiment to explore the implementation effect of variable teaching mode,using the questionnaire to collect experimental data,analyze the change of students' analogical transfer ability development level.The research results show that the variable teaching of chemistry in senior high school can effectively improve students' ability of analogy transfer,make students have a new experience of chemistry teaching methods,in the process of solving problems can extract key information from the subject,and carry on analogy,processing,transfer application,so as to improve the divergence of thinking.The author also puts forward some teaching suggestions,hoping to develop and integrate various teaching cases and expand the scope of practical research in the follow-up research.
