Research On Mixed Teaching Mode Of Chemical Core Concept Based On Macro-Micro Combination

The "General Senior High School Chemistry Curriculum Standards(2017 Edition)" points out that chemical core literacy is the basic requirement of academic chemistry for middle school students,and the macroscopic identification and microscopic analysis and the constructive nature of the chemical core concept mutually promote each other.The study found that China is too monotonous in the field of chemical core concept research,with narrow research scope and insufficient depth.In order to solve the problem of teaching the core concepts of Chemistry,the main contents of this study are as follows:(1)Using literature research,questionnaire survey,and individual interview research methods,combing the domestic and international chemical core concepts,macro-micro,mixed teaching model background and current situation,expounding the purpose and significance of this research.Based on the theory of Bruner and Ausubel as the basic theoretical basis,this paper studies the hybrid teaching design ideas of chemical core concepts from the perspective of macro and micro,and proposes innovative points to solve the problem of chemical core concept teaching.(2)Defining the concepts of chemical core concept,macro-micro and core literacy,combined with the current mixed teaching model,with the goal of cultivating chemical core literacy,constructing a mixed teaching model suitable for the core concepts of chemistry,and Perform a detailed analysis.(3)Inductively classify the core concepts of high school chemistry,explore the core concepts of the chemical from a macro-micro perspective,select and design a typical teaching case for ion reaction,practice design,and design statistical questionnaires and interview questions for statistical analysis of practical teaching effects.Provide reference for core concept teaching and mixed teaching model reform.The research shows that this model is not only conducive to solving the core concept teaching problems,achieving personalized teaching,but also promoting the cultivation of students' core literacy.
