Analysis And Enlightenment Of "Model Cognition" In "Basic Requirements For Chemistry Teaching In Senior Middle Schools"

The essence of chemistry is derived from the value of the discipline,that is,the attribute ability of chemistry that promotes the survival and development of students' subjects.Specifically,it is the students' understanding of things and solving problems from the perspective of chemistry through the study of chemistry knowledge The ideas,methods and views of concrete manifestation are the conscious or thinking habits of individuals taking the initiative to use chemical methods to recognize things and deal with problems.They are the general viewpoints obtained on the basis of re-sublimation of chemical knowledge.As the "evidence reasoning and model cognition" in the core chemistry of chemistry,the target of "model cognition" is to base on the inherent laws of material changes to make the model hypothesis and model building ability,and to help students to establish a basic solution to the chemical problem Framework,thus realizing the "chemistry from the perspective of understanding things and ideas,methods,ideas," the value of chemistry.Therefore,this study analyzes the basic requirements of high school chemistry teaching from the perspective of “model cognition”.The “basic requirements for high school chemistry education” referred to in this paper is organized by the Teaching Research Office of the Shanghai Municipal Education Commission and officially published in Shanghai in February2017.The basic requirements for the teaching of high school chemistry in the city"(hereinafter referred to as the "basic requirements for teaching").Through detailed analysis of the content and level of the "model" involved,the author guides the classroom practice and finally obtains inspiration from model teaching.It is believed that "model cognition" or "model-based cognition" is the recognition and grasp of chemical models."Model cognition" is a new term proposed by the new curriculum standard.This paper takes "model" itself as an important target of cognition.It is considered that "model cognition" is a key capability that needs development.For this reason,the author mainly did two aspects of work:(1)Analysis of "basic teaching requirements." Combing the six topics of "basic teaching requirements" on the model of the specific content,classification and level of learning to determine the level of support for the theory,the author based on classroom teaching experience,describe the actual teaching students behavior and teachers Behavioral operation;(2)application of "basic teaching requirements." Based on the above analysis results,I guide the author how to use the analysis results in teaching model teaching,the initial attempt and application in the actual teac hing,writing a specific teaching case,and the practice of the classroom,access to some of the insights of model teaching.Finally,the whole study is summarized,suggestions are put forward,and the defects are reflected.
