Research On Macro-Identification And Micro-Exploration Of Core Literacy Of Students Based On Unitary Holistic Teaching

The new chemistry curriculum standard in 2017 edition puts forward the specific standards for academic content from the perspective of depth and breadth.For the depth level,there are four levels of academic quality;for the breadth level,it puts forward several training dimensions,including "macro identification and micro analysis","variation concept and balance thought","evidence reasoning and model cognition","scientific exploration and innovation awareness" and "scientific attitude and social responsibility".The core of this study is around "macro identification and micro analysis",and it analyzes how to cultivate this aspect.For this dimension,it is not only a macro or micro requirement for students,but also a combination of the two.At the macro level,it needs to be able to distinguish and recognize the phenomena,clarify the mechanism,analyze the internal logic,build the relationship with the micro,cultivate the corresponding chemical concepts and understand the close relationship between the structure and the nature,namely that nature is the manifestation of structure and structure is the internal determinant of nature.This can help students to better grasp the essence of chemistry,and is also conducive to transferring application.The research based on the original research and involved theory of teaching around the macro and micro perspectives,this paper investigates the cultivation degree of "macro identification and micro analysis",and interviews chemistry teachers.Based on the survey results,it is found that the current combination of macro and micro dimensions has reached a medium level.It is better to grasp something in learning related knowledge,but people don't fully grasp this way of thinking.It is difficult to apply it to other areas of knowledge or the needs of daily life.Because of these shortcomings,the author proposes the training strategies for further improving the cultivation of macro and micro concept literacy,taking a lesson “Ion Reaction” as an example.
