The Study On High School Geometry Teaching Design Under Technology Empowerment

As an auxiliary means of teaching,Information technology has been deeply applied to middle school mathematics teaching.With the introduction of the concept of enabling,education under the enabling of technology has been paid more and more attention by the educational circle.It is emphasized that the application of information technology in teaching should be transformed from learning with the aid of information technology to learning with the change of information technology.The abstraction,logic and wide application of high school geometry lay an important position in high school mathematics curriculum.Using information technology to carry out technologyenabled geometry teaching can optimize classroom teaching efficiency,transform students' learning methods and promote teachers' professional development.Under the support of relevant theories and the background of the information age,this paper tries to construct a high school geometry teaching design case with technology enablement,from the theoretical level to the practical level,and provides theoretical and practical reference for middle school mathematics teachers to carry out geometry teaching design with technology enablement.This paper carries out research through literature research,questionnaire survey,interview and case study.Firstly,the necessity and feasibility of the research are clarified by analyzing and sorting out relevant literature and materials,such as technology enabling,geometry teaching,mathematics teaching design and geometry learning theory.On this basis,through the questionnaire survey and interview to the students and teachers,grasp the students and teachers' views on the application of information technology in geometry teaching,and find out the shortcomings of the application of information technology in geometry teaching.According to the results of the survey analysis,the constructivism learning theory,learning theory,under the support of geometry in combination with the characteristics of high school geometry knowledge,sums up the technology can assign under high school geometry teaching design about five of the six principles and strategy: objective principle,the establishment situation principle,exploratory principle,seepage mathematical thinking principle,efficiency principle,adaptive principle;With the help of information technology,we can create teaching situation,guide students to explore,enrich teaching methods,change students' learning methods,and accurately evaluate students' learning effects.The principles and strategies proposed above are used to construct the teaching designs of "the volume of the sphere" and "the ellipse and its standard equation" with the help of information technology and carry out teaching practice.After teaching,teaching reflection is carried out and students are interviewed to explore the enabling effect of information technology in geometry teaching.The research shows that the technology-enabled geometry teaching can optimize the classroom teaching efficiency,change the students' learning style,and promote the professional development of teachers.Specifically,technology can assign high school geometry teaching can use information technology to improve the situation of the import way to stimulate students' interest in learning geometry,and representation of knowledge with the help of information technology development process to help students understand the geometry knowledge,the rational use of information technology to train students' intuitive geometry,the implementation of the cultivation of the core of mathematics literacy,promote the development of mathematical thinking and so on.
