The Model Of "Research And Post-teaching" In High School Chemistry Teaching Explore And Practice

The "research and post-teaching" model is a teaching practice method that runs through the front,middle,and back of the classroom,based on many theories,using the "research plan" as the carrier,and in the form of student independent cooperative learning and teacher tutoring."Research and post-teaching" runs through the three links before,during and after the classroom.It can not only meet the requirements of the new chemistry curriculum standard to "make students the'master' of the classroom",improve the efficiency of classroom teaching,and let students in the process of problem-solving Training and enhancing the ability of cooperative inquiry,and can promote the realization of the "integration of teaching,learning,and evaluation".Based on this,this thesis attempts to explore and practice the application of the "research and post-teaching"model in the teaching of chemistry in the first year of high school,in order to open up new ideas for the teaching of chemistry in the first year of high school.This study firstly reviewed and sorted out the research content of the "research and post-teaching" model at home and abroad through the literature analysis method,and used the questionnaire survey method and interview survey method to understand the current situation of chemistry classroom teaching in the first grade of a middle school in Yinchuan City,and on this basis Through the guidance of cooperative learning theory,humanistic learning theory,constructivist learning theory and multiple intelligence theory,the "research and post-teaching"model is compared with scientific inquiry-based teaching and knowledge logic sequential teaching,and the "research and post-teaching" model is proposed.The guiding ideology and design principles of the company construct a teaching model of "research and teaching".Select the content of the compulsory high school chemistry compulsory one "Redox reaction" and "Elements enriched in seawater-Chlorine" in the People's Education Edition for teaching case design,write a classroom teaching carrier "research plan",and study it in a middle school in Yinchuan City,Ningxia In the first grade,two parallel classes are selected for teaching practice.The experimental class adopts the "research and post-teaching" model for teaching,and the control class adopts the traditional model for teaching.After practice,the practical effect is tested through the test paper test method and the questionnaire survey method,and the improvement of the "research and post-teaching" mode on the students' academic performance and comprehensive ability is analyzed.It provides references for the application research of the "research and post-teaching" model in high school chemistry teaching.The research results show that the "research and post-teaching" model has a certain effect on the improvement of students' cooperative exploration and communication skills;Using the"research plan" to preview before class helps students establish the connection between the new and old knowledge;the use of "research plan" to guide students in class helps to give full play to the student's main role;the use of "research plan" to review after class is helpful To construct a knowledge system for students;and the application of the "research and post-teaching" model in high school chemistry teaching can enhance students' classroom concentration,stimulate students'learning initiative,and improve students' academic performance.Therefore,the "research and post-teaching" model of high school chemistry teaching proposed in this research has certain practical value.
