Research On The Cultivation Of The Core Literacy Of "macro-recognition And Micro-analysis" In Middle School Chemistry Teaching

In the chemistry curriculum standards(2017 edition),the chemical core literacy was elaborated from five dimensions at the first time.Among five literacies,“macro identification and micro exploration” was the focus in this thesis.It was the basis for the cultivation of other four core literacies,which emphasized on the identification of specific substances from macro phenomena,and the understanding of the intrinsic properties of substances through micro exploration and analysis,accordingly establishing the relationship among “substances,structures and properties”.In this thesis,the teaching strategies aimed at the cultivation of core literacies in different stages were proposed,which based on analyzing the characteristics of junior and senior school students taking the knowledges of element compounds as carriers.It would provide not only some methods and ideas for teachers in training students' core literacies,but also theoretical basis for other scholar's research.There were six parts in this thesis.Part1: Introduction.This part mainly summarized the background,research situation and significance of the thesis.It focused on the research status of “macro identification and micro exploration” core literacy at home and abroad.Part2: Related concepts and theoretical basis.The concepts related to core literacy were differentiated in this part.At the same time,the relationship between the five dimensions of core literacy was expounded,and the theoretical bases applied in this thesis were listed also.Part3: The contents analysis of “macro identification and micro exploration” in middle school textbooks.The contents of elemental compounds in junior and senior high school were characterized,at the same time,the curriculum standard and the different situations of students in different stages were analyzed.Part4: Comparison of instructional design.The traditional instructional design was compared with the instructional design based on “macro identification and micro analysis” in terms of connotation,thinking,contents and the design of instructional goal.The similarities and differences between above two instructional designs had been found and summarized.Part5: The proposal of teaching strategies.Different teaching strategies had been put forward in view of the different stages of junior and senior high school,and the practice research had been done.Part6: Summary and prospect.In this part,the research results were summarized,at the same time.It also prospected the future research directions of “macro identification and micro exploration”.
