Research On The Application Of Interactive Electronic Whiteboard In The Teaching Of "Graphics And Geometry" In Junior Middle School Mathematic

With the development of information technology,the appearance of interactive electronic whiteboard has changed the traditional teaching methods.A new type of teaching media has emerged in the classroom of primary and secondary schools.With its powerful intuitiveness,interaction and intelligence,it has constructed a new teaching situation and become an important carrier of classroom teaching."Figure and geometry" as an important field in junior middle school mathematics,its logic,abstractness is strong,for the training of students mathematical thinking,the development of geometric intuition and space concept,improve the core literacy of students mathematics has an important role.Starting from the teaching practice,this study takes the teaching content of "figure and geometry" in junior middle school mathematics as an example,and reviews the research trends at home and abroad on the basis of extensive literature review.With constructivism learning theory,learning theory of multiple intelligences Gardner,information technology and curriculum integration theory and interactive teaching theory as the support,through questionnaire investigation and interview method to understand ordinary junior high school and junior high school of interactive electronic whiteboard in the application status of graphics and geometry teaching,comprehensive questionnaire and interview results,it is concluded that application of advantages,problems and put forward feasible Suggestions,On this basis,the teaching design and practice of "graphics and geometry" are carried out.Through the integration of interactive electronic whiteboard and teaching design and teaching record fragments,the use and function of interactive electronic whiteboard in junior high school graphics and geometry teaching are presented,and research conclusions are drawn:(1)The interactive electronic whiteboard breaks the traditional teaching mode and learning mode,and has been recognized and used by most front-line teachers,which is conducive to teachers’ teaching and students’ learning,and improves students’ interest and enthusiasm in mathematics learning;(2)There are also some problems in the use of electronic whiteboard by teachers.The interaction between teachers and students should be fully considered,professional and technical training should be strengthened,and the integration of mathematics subject and electronic whiteboard should be fully considered to optimize classroom structure and improve teaching effectiveness;(3)In the teaching design,we should focus on improving students’ thinking ability and learning level,and let the electronic whiteboard assist teachers’ teaching and students’ learning.
