Research On Instructional Space Vector Based On Analogical Transfer Theory

Space vector is the basic knowledge of three-dimensional space and has always been the focus of high school science students.Learning space vector in high school also provides preliminary knowledge for further study in the university.Therefore,this paper carries out teaching research on this part.The use of analogical transfer theory is a relatively popular teaching method.Therefore,based on the practical background of the research and the structure mapping theory,practical schema theory and example theory in the analogical transfer theory,this paper mainly studies the schema construction and problem solving of high school students in learning space vector,and how to carry out analogical transfer teaching in the space vector.This paper adopts literature research method,test survey method,questionnaire survey method,interview research method and experimental research method,and finds that students' schema construction and problem solving ability have strong consistency in all aspects of space vector.Hence,the focus of teaching should be to guide students to effectively construct space vector correlation schema.However,the survey found that students' level of schema construction is not strong.Although teachers generally recognize the use of plane vectors for analogical transfer teaching in the current and take certain methods to improve,the focus is still forcing students to do lots of exercises.However,both teachers and students recognize the closeness of the knowledge relationship between space vector and plane vector,which makes it possible to use the similarity of plane vector and space vector to make analogical transfer teaching.After fully studying the teaching situation of the current space vector,this paper proposes teaching suggestions: Optimize the analogical form and select the analogical link;Summarize in time and reflect on learning methods;The examples are progressive to optimize the schema structure;Focus on geometric features and grasp the nature of the problem.Then integrate these suggestions into specific space vector teaching activities and conduct experiments.The results of the experiment also showed that although the students were slightly unfamiliar with this type of teaching in the initial stage,they were able to accept it quickly and also performed well in the final test.Therefore,using the theory of analogical transfer theory to teach space vectors,students can grasp the essence and solve problems quickly.
