The Practical Research Of Chemistry Life Teaching In Senior High School Under The Background Of New College Entrance Examination

In recent years,a new round of high school curriculum reform has been carried out in succession throughout the country in order to fully implement the party's education policy,and Chongqing also officially entered the new curriculum reform in2018.As the standard and "baton" of curriculum reform,the "General High School Chemistry Curriculum Standards" of 2017 edition requires teachers to focus on the theme of "developing students' core literacy in chemistry" in chemistry teaching and evaluation,optimizing the teaching process,effectively improving the quality of teaching,developing quality-oriented education,and implementating the fundamental tasks of foster virtue through education.Therefore,the traditional teaching model based on textbook knowledge can no longer meet the requirements of the times.Teachers must deeply understand the connotation of core literacy in chemistry,integrate textbook knowledge with real life in the teaching process,and strengthen the connection between students' real life,modern society and the development of modern science and technology.Meanwhile,teachers must also pay attention to students' learning interests and experience,and implement the unique educational value of chemistry to students.The return of chemistry teaching to life is to meet the needs of the development of the times,and it is also a necessary way to cultivate students' core literacy.Therefore,the research on life-oriented teaching has received extensive attention in recent years.Through reading a large number of documents and consulting related libraries such as How Net Weipu,we can find that in the past ten years,domestic chemistry teaching has grown from scratch to general research,and then in-depth development trend in the future,which shows the feasibility,inevitability and importance of chemistry teaching in daily life.This thesis is a practical research on the integration on the high school chemistry disciplines and the concept of "life-oriented teaching" to meet the needs of the new curriculum reform.The research of this paper is mainly divided into the following four parts:The first part(chapters one and two)is the theoretical research part.The literature analysis method is used to analyze the background,research theories and significance,research ideas and research methods of high school chemistry life-oriented teaching.This part summarizes the research status of life-oriented teaching at home and abroad and the theoretical basis of life-oriented teaching,which provides theoretical support for the whole research.The second part(Chapter 3)is the investigation and analysis part.Through the questionnaire analysis method,classroom observation method and other methods to analyze the concern extent of students to chemistry in daily life in the actual teaching,students' views on life-oriented teaching,the current situation of life-oriented teaching implementation,and some problems existing in the current teaching process,which provides a practical basis for the research.According to the survey results,the vast majority of students support the teaching concept of "life-oriented teaching" and agree that the combination between theory and practice can improve their learning interest and help them understand learning.Almost all teachers have more or less adopted the life-oriented teaching model to visualize the abstract concepts of chemistry by combining with the real life,making it easier for students to understand and be more impressive on the knowledge.The third part(Chapter 4)is the practice case part.By studying excellent life-oriented teaching cases,the advantages of this pattern and the feasibility of practicing in my own teaching were analyzed compared with traditional teaching.Then,the teaching cases and teaching activities are designed using the high school chemistry textbook of the People's Education Edition as materials for life-oriented teaching.By studying the STEAM course "Ethnic Printing and Dyeing STEAM Course—Bai Tie-dyeing" from the Middle School Affiliated to Minzu University of China(hereinafter referred to as the Affiliated Middle School of Minzu University),the author analyzed its advantages and feasibility,and then designed the innovative experiments of the "Initial Preparation of Ancient Perfume",organized students to visit waterworks and sewage treatment plant and other practical activities,and accomplished "colloid" and other practical teaching design.The fourth part(Chapter 5)is the summary and elaboration part.The author got the enlightenment from the research and made suggestions for the life-oriented teaching of high school chemistry.According to the research results,the paper summarizes and analyzes the advantages and disadvantages of the high school chemistry teaching practice process and puts forward expectations on life-oriented teaching of high school chemistry.
