Research And Practice Of Middle School Chemistry Experiment Innovation Based On Core Literacy

Nowadays,the world is undergoing great development,transformation and adjustment.Cultivating innovative talents is of vital importance to the development of a country.In order to meet the needs of The Times for talent training,core literacy has taken root in China.The main purpose of "Chemistry Curriculum Standards for General High Schools（2017 Edition）" is to develop students’ chemistry core literacy.Taking experiments as the basis is one of the important characteristics of chemistry.In order to give full play to the teaching function of experiments,some experiments that have deficiencies in textbooks can be improved and innovated to achieve better teaching effects and promote the development of students’ core literacy in chemistry.Therefore,this research takes core literacy as the guide,combines theory and practice,improves and innovates middle school chemistry experiments,and applies them to classroom practice,which has a positive effect on the implementation of core literacy.First of all,by collecting a large number of literature,to understand the background and current situation of the current core literacy and innovation of chemistry experiments in middle schools,and to integrate relevant concepts and theoretical foundations.Secondly,the author conducts a questionnaire survey and teacher interviews in Middle Schools directly under Zhangzhou,to understand the current situation of chemistry experiment teaching and experiment innovation in middle schools,and to provide the basis and direction of practice for this research.Finally,combined with the characteristics of chemical experiment teaching,this study constructed a model of chemical experiment improvement and innovation based on core literacy.In order to test the feasibility of the model,select three experiments of high school chemistry textbook（Jiangsu Phoenix Education Press）"ion reaction" "copper and concentrated,dilute nitric acid reaction" and "primary battery" to improve and innovate.Taking two parallel classes in a middle school in Zhangzhou city as the object of implementation,implement the middle school chemistry experiment teaching based on core literacy,and determine the feasibility and implementation effect of the research through the comparison and analysis of the test data in the early stage and the later stage.Through the research and practice of this paper,it is found that the effective improvement of chemical experiments and the development of experimental teaching is conducive to the development of students’ core literacy of chemistry,and to exert the important function of chemical experiments in middle school chemistry education and teaching;To construct the model of improvement and innovation of middle school chemical experiment based on core literacy,and summarize experimental improvement and innovation strategies with innovative models,that is,innovative design can be carried out from the perspective of operation and device improvement,experimental conditions research,environmental protection and the output form of transformation information;Through experimental improvement and innovation case study and practice,good teaching effect has been achieved,which is an effective way to improve the quality of teaching,and provides reference cases for the front-line teachers of middle school to improve the experimental improvement and implement the experimental teaching.
