The Cultivation Of The High Students' Key Competencies On Macroscopic Identification And Microcosmic Analysis

At the beginning of 2018,The chemistry curriculum standard(2017 Edition)was officially released,in which the breadth and depth of academic content are clearly required.In the breadth,the chemistry key competencies is divided into five dimensions "macroscopic identification and microscopic analysis" and " the concept change of thought of balance" and "evidence reasoning and model understand","science exploration and innovation consciousness","scientific attitude and social responsibility",in depth,the academic quality is divided into four levels.The cultivation of the high school students' key competencies on macroscopic identification and microscopic analysis are studied in this paper.In this dimension of core literacy,it is emphasized that learning chemistry is not from a single macro or micro angle,but from macroscopic phenomena to identify explain,analyze,deduce the connection with microstructures.And the macro and micro connections of properties decided by structure and structure reflected by properties are known,which is very helpful for students to learn chemistry.And the training of this dimension is twice the result of learning other disciplines and linking production and life.This article through questionnaire survey method,interview method,data analysis.research introduction,the related concepts and theoretical basis,a survey of "macroscopic identification and microscopic analysis" of high school students,the training strategy of " macroscopic identification and microscopic analysis".Based on the summary before the teaching experience and relevant theories on macro micro connection,through the investigation on the current key competencies training status of high school students about macroscopic identification and microscopic analysis and a summary of interview with chemistry teachers,the results show that the level of the micro and macro connection of the senior middle school students is in the upper level students pay more attention to the learning of chemistry knowledge,while ignore the learning of the knowledge brought by the way of thinking and literacy applied to living and learning in other subjects.In view of the above problems,three training strategies combined with curriculum standards are put forward,which are regrasping teaching contents,emphasizing chemical experiments,inspiring scientific thinking,implementing teaching,learning and evaluation,and effectively teaching feedback.It is hoped that more scholars and educational work can be caused by throwing bricks into jade.
