Research On Chemistry Unit Teaching In Junior Middle School Under The Guidance Of Core Literacy

In order to further promote a new round of curriculum reform,the new curriculum standard proposes to construct a chemistry curriculum content system under the guidance of big concept,give full play to the comprehensive education function of chemistry curriculum,and plan the overall development of chemistry core literacy.However,for a long time,domestic teaching is generally designed by a single class hour,lack of integrity,comprehensive and systematic characteristics,so the large unit teaching arises at the historic moment.Large unit teaching is a new teaching design mode to deepen the reform of chemistry teaching,actively explore the essence of the core quality of the subject,and adapt to the development of chemistry education in the future.In recent years,large unit teaching oriented by discipline core literacy has become a research focus of current education reform.While some experts and scholars are actively conducting theoretical research,how to effectively test the teaching results of large unit has become a concern of front-line teachers.This study firstly reviews the current research situation of subject core literacy and large unit teaching at home and abroad through text analysis method.On this basis,the focus of this study is put forward,that is,to pay attention to the research of chemistry large unit teaching in compulsory education stage,and to reflect the integration of different attainments in specific lesson examples.The second part is theoretical exposition.Combining with relevant theories such as deep learning and project-based teaching,this study expounds the theoretical basis and relevant enlightenment of chemistry large unit teaching in junior middle school,and carries out process design and characteristic analysis of large unit teaching under the guidance of core literacy.The third part is practical discussion.Through interviews,front-line teachers are interviewed to understand the implementation status of large unit teaching in the stage of compulsory education and the problems encountered in the development process,including how to construct the main line series situation to make the integration of knowledge better complement each other and how to evaluate the implementation of core literacy.Then to chemical course textbooks for compulsory education schools are the seventh unit "combustion and extinguishing",for example,in the new standard of comparison and different versions of textbooks,and on the basis of consulting relevant teaching design paper literature,designed to "ignition threshold to controlling the art of fire,fire and mechanically" unit as the main line of the overall framework and specific implementation in practice school's class;Finally,the results analysis part,through the unit test method and questionnaire survey method,in the form of Likert scale investigation students in different dimensions of compulsory education chemistry discipline core literacy,and with the help of SPSS26.0 analysis of the results,come to the conclusion: The chemistry unit teaching of junior middle school under the guidance of core literacy not only helps to improve students' academic performance,but also helps to implement the core literacy of the subject,especially in the dimension of scientific thinking,scientific attitude and responsibility.
