Research On Core Literacy Based On Evidence Reasoning And Model Cognition

Core literacy is the main goal of training in the new curriculum,and plays an important role in the reform of new curriculum education and teaching.Chemical core literacy is the key literacy in solving chemical related problems during the development of students' cognitive activities.Evidence reasoning and model cognition is one of the basic contents of chemistry core literacy.Integrating evidence reasoning and model cognition into chemistry experiment teaching activities,establishing evidence reasoning and model cognition consciousness,internalizing model cognition and evidence reasoning into an inherent learning mode,is an important way to cultivate students' chemistry core literacy.This paper focuses on the research of the core literacy of "Evidence Reasoning and Model Cognition" in junior middle school chemistry experiment teaching.Taking the case of junior middle school chemistry experiment teaching as the research object,this paper attempts to explore the core literacy of "Evidence Reasoning and Model Cognition" in the context of the core literacy of chemistry experiment teaching.Following is a brief introduction of the research content: This paper uses the methods of literature,case and interview to conduct in-depth research.Firstly,it collects and collates the data about the research status of chemical core literacy at home and abroad and the current research status of chemical experiment teaching.On the basis of consulting a large number of data and investigating the actual situation of current education and teaching reform,according to the current research of chemical core literacy.Based on the results of interviews with front-line teachers and my own teaching practice,this paper explores how to improve students' core literacy of "evidence reasoning and model cognition".Secondly,"Evidence Reasoning and Model Cognition" is presented in the junior middle school chemistry experiment teaching.This paper mainly analyses the demonstration of "Evidence Reasoning and Model Cognition" in the middle school entrance examination experiment inquiry questions and the experimental teaching cases of "Combustion and Fire Extinguishing","Carbon Dioxide Production","Molecule and Atomic".This papersummarizes and summarizes the experimental models of gas preparation device,collection device and tail gas treatment device in junior middle school chemistry experiment teaching,and the cognitive models of the classification,chemical changes and chemical terms of the related elements and compounds.Finally,the strategies of cultivating students' core literacy of "evidence reasoning and model cognition" in junior middle school chemistry experiment teaching are put forward,that is,integrating junior middle school chemistry experiment teaching resources,enhancing students' ability of evidence reasoning,systematizing experiment teaching and guiding students to construct cognitive model.Through the case study of junior middle school chemistry experiment teaching,this study draws the following conclusions:(1)help students build up model consciousness on the basis of evidence reasoning ability;(2)guide students to express model in an appropriate way and construct specific cognitive model;(3)guide students to Establish the Thinking Model of Scientific(4)Inquiry systematize junior middle school chemistry experiment teaching,so that students' evidence reasoning and model cognitive core literacy ability are obvious.Improvement.
