Research On The Construction Of Thinking Model In Senior High School Chemistry Teaching Based On Model Cognition

The construction of thinking model is an important scientific thinking method and cognitive means.In teaching,teachers should not only impart necessary chemical knowledge and book content to students,but also infiltrate and cultivate students' scientific learning methods.Constructing thinking model can help students understand the essence of knowledge acquisition and abstract conceptual and theoretical knowledge.In the process of scientific inquiry experiment,students can explore the essence of phenomena,improve their thinking ability and enhance their ability to solve chemical problems.Through consulting and collating and analyzing the relevant literature,taking the research of thinking model construction in senior high school chemistry teaching as the main line,taking constructivist learning theory and Ausubel's meaningful learning theory as the theoretical basis,this paper defines the relevant concepts of model,thinking model and model construction,and revises and compiles students and teachers on the basis of previous research through questionnaire survey method.Questionnaire,to understand the basic situation of students' thinking model construction in chemistry teaching and teachers' current situation of infiltration and cultivation of middle school students' thinking model,find out the problems and shortcomings in teaching,and give preliminary teaching suggestions.Through literature and investigation and analysis,it is proposed that effective teaching strategies of thinking model construction are to construct thinking model of element compounds based on material category and valence law,to construct concepts and theoretical thinking model based on core knowledge system,to establish scientific inquiry thinking model guided by experiment,to create real situation,to establish problem-solving thinking model,and to set up activity tasks to promote thinking.Five teaching strategies for building dimension model.Using the method of educational experiment,set up the experimental class and the control class,throughthe design and implementation of specific teaching cases,use SPSS software to quantitatively analyze the teaching effect,compare and analyze the results of the pre-test and post-test chemistry.From the data,it can be seen that the construction of thinking model in chemistry teaching can effectively improve students' chemistry learning performance;through student interviews,we can understand the influence of the method of building thinking model on students' learning interest,attitude,mode of thinking and habits in chemistry learning,and show that the method of building thinking model can improve students' thinking and problem-solving ability.Finally,according to the results of theoretical research and practical research,it is concluded that the method of constructing chemical thinking model can not only improve students' chemistry achievement,but also stimulate their interest in learning,so as to master the core knowledge of chemistry,enhance the ability of problem solving and thinking ability,which proves that the method of constructing thinking model in chemistry teaching is effective.Of course,there are still many limitations and shortcomings to be improved in this study.In the future teaching research,this study will continue to be enriched and improved.
