Teaching Research On Cultivating “Macro-Identification And Micro-Analysis” Literacy Of Senior High School Students Based On Mind Map

As one of the core literacy of chemistry discipline,“macro-dentification and micro-exploration” literacy reflects the unique chemical concept and chemical thinking of chemistry discipline,which runs through the whole high school chemistry learning and is very important.Through literature research,it is found that mind map has unique advantages in cultivating the “macro-dentification and micro-exploration” literacy of senior high school students.However,there are few relevant researches,which are not systematic and perfect enough.Therefore,this paper carries out the teaching research based on mind map to cultivate high school students’ “macro-dentification and micro-exploration” literacy,in order to supplement relevant theoretical and practical researches.Through literature research,this study sorted out the relevant research status,concept definition and theoretical basis of mind map and “macro-dentification and micro-exploration” literacy.The teaching content of“macro-dentification and micro-exploration” literacy was defined,the advantages of mind map were analyzed,and the teaching strategies of cultivating high school students’ “macro-dentification and micro-exploration” literacy based on mind map were put forward.According to the proposed teaching strategies,the teaching design of “the properties and applications of chlorine gas”,“redox reaction” and “the properties and preparation of sodium”were completed,and the teaching practice research was carried out in the actual teaching.Using data analysis method and student interview method to analyze the results of practical research,the following conclusions are drawn: The application of mind map in the teaching of“the properties and applications of chlorine gas”,“redox reaction” and “the properties and preparation of sodium” can effectively cultivate students’ “macro-dentification and micro-exploration” literacy,and improve students’ grades;Students hold a positive attitude towards the application of mind map in classroom teaching.
