Research On Visual Teaching Of Primary Mathematics Under The Tpack Framework

In today's society,the concept of"Internet+mathematics education"is born,and mathematics education technology is considered as the most important tool for the implementation of this concept.The 19^th chapter of National Medium and Long-term Education Reform and Development Plan Outline?2010-2020?,points out that Information technology has a revolutionary influence on education development,so we must give pay great attention.Besides,we have to attache great importance to the application of information technology,and to realize the depth of the information technology and mathematics curriculum integration.The TPACK first suggested by developed countries offers a new thought for the further implementation of our education reform.The primary math is the foundation for the mathematics learning in the future,while among primary math,the plane geometry is the key content of elementary school,playing an important role in the cultivation of abstraction thinking and intuitive imagination.This article take plane geometry as an example,and design visualized teaching strategies under the framework of TPACK,helping the students understand the importance of plane geometry,assisting the teachers to handle the difficulties,and trying to improve the efficiency of classes.This article focuses on theory and practice research.On theory research,this article first elaborated on the core concepts of TPACK,plane geometry and the teaching of primary math through methods of experience and theoretical thinking.Then,this article designed the strategy of primary plane geometry under the framework of TPACK:Vividly-Visualized Situation,Visualized Cognitive Process,Dynamic Multiple-Relation,Clearly-Identified Cognitive Results.On practical research,the research method of"teaching experiment+questionnaire survey+semi-structured interview?is implemented,and visual teaching strategy is applied to the teaching practice,in order to test their understanding of students'mathematics belief,mathematics emotional attitude,mathematics learning,and mathematics learning ability.Research shows that:?1?the math grades of experimental class students were improved significantly.?2?the experimental class student's mathematics understanding beliefs,emotional attitude,learning methods were improved significantly.?3?the experimental class student's mathematics learning abilities were not improved significantly.
