Research On Promoting High School Students' "Evidential Reasoning And Model Cognition" Literacy Based On Mind Mapping

With the rapid development of the social economy,the society has put forward higher requirements for the quality of talents.For chemical literacy,it has been pointed out in the "Standards of Chemistry for Senior High Schools(2017)" that the core literacy of the chemical includes five aspects of "macro identification and microscopic analysis","change ideas and balanced thinking","evidence reasoning and model cognition"."Scientific inquiry and innovation awareness","scientific attitude and social responsibility".The literacy of "evidence reasoning and model cognition" is conducive to cultivating students' close thinking and rigorous scientific attitude,improving the ability of classification,induction and summarization,and establishing model cognition.This thesis mainly discusses how to apply the mind map to high school chemistry teaching to enhance students' literacy of "evidence reasoning and model cognition".The specific research is as follows:(1)Obtain the connotation and recently research of mind map and chemical core literacy by consulting the literature,and compile questionnaires based on the results of comprehensive literature review.(2)Through the questionnaires and other studies to understand the high school students' cognitive level of mind mapping and literacy of "evidence reasoning and model cognition".(3)According to the results of the questionnaire research,the teaching case is designed for the content of “Evidence Reasoning and Model Cognition” for high school students to the content of the third chapter of “Metal and its Compounds”.(4)Applying the teaching case to the classroom teaching practice,and discussing the influence of the practice of the case on the literacy of the high school students' "evidence reasoning in model cognition",and finally interviewing the experimental class teachers,parallel class teachers and students respectively.The results of the study indicate:(1)In terms of learning attitudes and methods,students' interest in learning is improved,which is conducive to cultivating students' awareness of using information technology services to learn,broadening learning channels,and helping students to form good study habits.(2)In terms of chemical core literacy,students' reasoning ability,analytical ability and modeling consciousness are improved,which is beneficial to improve students' "evidence reasoning and model cognition" literacy.(3)In terms of the comprehensive application of knowledge,students' ability to explore and solve problems in learning chemistry courses has improved.(4)For teachers,the addition of mind maps helps to improve the efficiency of teaching preparation before class,and helps teachers organize and carry out classroom teaching.
