Research And Practice Of Chemical Cohesion Methods In Junior And Senior High School From The Perspective Of Transfer Theory

As an important educational theory,transfer theory connects and integrates old and new knowledge and plays an important role in students’ learning.Every teacher should fully combine transfer theory with teaching to promote students’ learning.Students entering senior high school are in a critical period of physical and mental development,and the study of all subjects is at a new starting point.Therefore,it is very important for students to do a good job in the connection between junior and senior high school chemistry.This thesis analyzes the linkage point of chemistry knowledge in junior and senior high school,studies the linkage method of chemistry in junior and senior high school from the perspective of transfer theory,promotes the application of transfer theory in linkage chemistry teaching,builds a linkage chemistry teaching model in junior and senior high school,stimulates students’ learning interest,provides teachers with linkage chemistry teaching experience and cases,and promotes the teaching of chemistry subject.The thesis is divided into the following four parts.The first part expounds the research background and significance,determines the research content and research methods,and summarizes the research status at home and abroad on the chemistry connection of junior and senior high school by collating and analyzing relevant literature in the past five years.The concepts of "transfer" and "cohesion" are defined,and the theory of transfer,constructivism,the zone of nearest development and the theory of advance organizer are expounded,which lays a theoretical foundation for the later teaching design and practice.The second part investigates and analyzes the current situation of chemistry connecting teaching in junior and senior high schools through questionnaire survey.Design a questionnaire for high school students and a questionnaire for high school teachers,distribute the questionnaire,and collect data for analysis.Summarize the current problems in chemistry connection between junior and senior high schools in terms of students’ learning interests,teachers’ awareness of connection,and methods of connection,laying a foundation for the next step in the proposal of connection methods.The third part,based on the connection problem,explores the connection point between high school chemistry required Course 1 and Grade 9 chemistry,proposes five connection paths of "chemical concept,chemical reaction,chemical calculation,chemical experiment and chemical structure",designs the connection method of "pre-class,in-class and after-class",and forms the systematic connection teaching of chemistry in junior and senior high school.Teaching design and practice are carried out according to the connecting teaching mode of chemistry in junior and senior high schools.After practice,the achievement analysis and questionnaire survey are used to test the effect of connection teaching,which proves the feasibility and effectiveness of the connection method.The fourth part,conclusion and prospect.The teaching practice proves that connection teaching can improve students’ performance,stimulate students’ interest,cultivate students’ ability and build a harmonious relationship between teachers and students,which proves that the connective method proposed in this study is feasible.
