Content Analysis And Implementation Strategy Research Of Safety Education In New Chemistry Teaching Materials Of Senior High School

Safety education is an important part of high school chemistry teaching,combining chemical safety education and teaching,in the high school chemistry teaching seepage safety education,conform to the ordinary high school chemistry curriculum standards(2017 edition,revised in 2020),"the basic requirements,is advantageous to the development of the students’ subject core literacy and cultivate the students’ safety consciousness,At the same time,it is beneficial to comprehensively understand and excavate the value of chemistry curriculum.The new textbooks(Humanities Edition 2019 edition)obviously strengthen the status of chemical safety education in middle schools,and the Chemistry Curriculum Standards for Ordinary High Schools(2017 Edition 2020 Revision)also put forward clear requirements on cultivating students’ "safety awareness" literacy.The purpose of this study is to strengthen the penetration of safety education in chemistry teaching,explore the implementation strategy of chemical safety education,so as to expand the students’ safety knowledge,enhance their safety awareness,and improve their ability to deal with chemical experiments and safety problems in life.In recent years,the studies of chemical safety education has aroused people’s attention,and more and more discussions have been made on the current situation and strategies of chemical safety education,while there are no reports about safety education content in the old and the new teaching material analysis and comparison and the implementation strategies of new textbooks and the design of teaching cases for teaching practice.This study focuses on the theme of "The analysis and implementation strategy of safety education in the new high school chemistry textbook".First,the research aim to make middle school chemistry teachers fully aware of the importance and necessity of infiltrating safety education in chemistry teaching by means of reported widely at home and abroad related research,understand the research present situation and the connotation of chemical safety education,comprehensive combing the general high school chemistry curriculum standard(2017 edition,revised in 2020)in the relevant contents of chemical safety education,analyze the old and new materials in the chemical safety education differences of knowledge content,clear the status of chemical safety education in the new teaching material.Additionally,with the help of teacher interview,teacher questionnaire and student questionnaire,the understanding of teachers on chemical safety education and the current situation of chemical safety education in teaching were understood,and the knowledge reserve of middle school students on chemical safety and their ability to deal with unexpected safety problems were collected.The results of the interview and investigation show that it is necessary to improve teachers’ understanding of the importance of osmotic chemical safety education in teaching,and to improve students’ ability to store chemical safety knowledge and deal with unexpected safety problems effectively through osmotic chemical safety education.Based on the analysis and investigation results of chemical safety education content in new textbooks,this paper puts forward the implementation strategy of effectively infiltrating safety education in middle school chemistry teaching: starting from deep digging of textbooks,creating scenarios,classroom experiments,and reading guidance,infiltrating safety education,In addition to micro-classes,homework,theme board newspapers,knowledge competitions as the breakthrough point to strengthen chemical safety education.Furthermore,three teaching cases of infiltration safety education are designed specifically: "sulfur and sulfur dioxide","test of sulfuric acid and sulfate ion" and "transformation of sulfur-containing substances in different valence states",in the case of Yongzhou No.X Middle School took one or two ordinary classes with similar basics as the research objects,and carried out a two-week teaching practice research on penetration safety education.The experimental class adopts the teaching cases of infiltration safety education,while the control class adopts conventional teaching.In the process of teaching practice,the implementation strategy of infiltrating safety education in teaching has been amended and improved.After the teaching practice,the students of the two classes were tested for safety knowledge,and their scores were collected and analyzed to understand the effect of infiltration safety education in middle school chemistry teaching.In a word,based on the comprehensive and systematic analysis of the chemical safety education content in the new textbooks,this study put forward the implementation strategy of effective infiltration safety education in middle school chemistry teaching and carried out the practice.The results can be used for reference in high school chemical safety education and teaching,and have certain theoretical and practical value.
