A Practical Study Of Chemistry Teaching In Senior Middle Schools Under The New Curriculum Standard

The core literacy mentioned in the Chemistry Curriculum Standard of Senior High School(2017)uses hot topics related to chemistry for teaching,and advocates the combination of life materials and chemistry textbooks.This research is to further explore the better implementation methods of high school chemistry life teaching under the support of the relevant content in the new curriculum standard,implement the cultivation of the core accomplishment of students' chemistry disciplines,provide services for the comprehensive development of students,and construct the chemistry life community.This article includes the following six parts:Part 1:Introduction.Study relevant literature and text materials to understand the background of life-oriented teaching research,and on this basis,refine the research status of such issues in the field of“life-oriented teaching”and "high school chemistry life-oriented teaching" at home and abroad.Starting from the part that has never been completed or implemented in the teaching,determine research content and choose the appropriate method to help complete the research.Part 2:the education teaching theory of high school chemistry life under the new curriculum standard.Through the review of relevant literature,the author summarizes the definitions of“life teaching”“chemistry life teaching”“high school chemistry life teaching”and“high school chemistry life teaching”under the new curriculum standard,and analyzes the expression of life-style teaching features in front-line education practitioners and new curriculum standards.Learning and sorting out the relevant educational teaching theories,the author draws the learning theories such as“recent development zone" "constructivism" and "metacognition" applied in the research process and teaching.In this way,it provides strong theoretical support for the design of teaching plans and the implementation of teaching concepts in the later period.Part 3:the current situation investigation and implementation method of high school chemistry life teaching.Through the students' questionnaires,the author understands the current teaching situation of the high school chemistry classroom under the requirements of the new curriculum standards,then provides a basis for the implementation method of life-oriented teaching;According to the hot vocabulary and the teaching situation of the practical school,consult the relevant literature and choose to apply the living environment education,network information,humanistic knowledge and daily living exercises in the classroom teaching of the practical school chemistry theory;In the experimental classroom teaching,the experimental theme,device,medicine and operation should be designed for life,which will provide practical support for the later life-oriented teaching research and program implementation.Part 4:Case design and implementation of high school chemistry life teaching under the new curriculum standard.Combine the actual teaching arrangements,analyze the textbooks,select the contents of"Ionization of Acids,Alkali,Salts in Aqueous Solutions" and "Sodium Carbonate and Sodium Bicarbonate" in the compulsory high school chemistry 1 to design the teaching case,analyze from the teaching materials,academic conditions and syllabus requirements separately,highlight the integrity of teaching objectives,methods,processes and the consistency of content design,use a variety of teaching activities in the life-oriented teaching mode to connect knowledge and situation,improve the logic of knowledge and the enthusiasm of students in the classroom,reflect the teaching requirements of the new curriculum standards,and then meet the development of students in the new era.Part 5:Analysis of teaching practice results.First of all,issue and collect after-school questionnaires,analyze the reliability and validity of the questionnaires,and understand their acceptance of high school chemistry life teaching under the new curriculum standard;then design after-school questions with a score of 30 that is related to life.The after-school questions will be tested in the experimental class and the control class.The analysis of the scores shows that the average score of the experimental class is 24.00 and the average class of the control class is 21.66.It can be seen that the use of life-oriented teaching in the experimental class meets the requirements of comprehensive development of students in the current new curriculum standards,and gradually cultivates students'awareness of collecting life materials,which can effectively help them understand the difficult knowledge in high school chemistry textbooks.Part 6:Research summary and prospects.Under the new curriculum standard,students will be able to take the initiative to collect life materials to increase their knowledge reserves.The teacher's case design reveals new ideas,sums up the deficiencies in the classroom,and provides an effective reference for front-line teachers to carry out life-style teaching.
