Abstract

The integration of information technology and mathematics curriculum is considered asone of the basic concept of the "ordinary high school mathematics curriculum standard(ex-periment)", required by the combination of information technology and mathematicscurriculum teaching, give full play to the advantages of information technology, and improveteaching efficiency, improve the teaching effect. In recent years, with the development ofinformation technology, the changing of teaching media, interactive electronic whiteboardgradually become the mainstream of teaching media products. But in the actual classroomteaching, the function of electronic whiteboard has not been fully used, its teaching effect is notobvious, at the same time, through literature search, the author found that the interactivewhiteboard teaching is used in Chinese, mathematics and foreign languages teaching, but verylittle, and even less for high school mathematics teaching. Therefore, the author aims to make aneffort to have a research of the three-dimensional geometry teaching of the electronic whiteboardin the high school mathematics and find out how to study more reasonably and more effectivelyfrom the angle of mathematics.Geometry teaching presents situations and existing problems, and furtherly analyze thecause of the problems through the related teachers’ individual interview, they are: lack ofrelevant professional training; less opportunity for the middle school students to draw pictures inthe classroom teaching, leading to unable to improve drawing ability; teachers only pay attentionto the classroom capacity because the shortness of the teaching time, ignore the interactionbetween students and teachers; the platform for sharing is not mature, lack of teaching resourcesand teaching case. Then, combined with the results of the above analysis, according to the goalof three-dimensional geometry teaching and difficult points, I put forward the electronicwhiteboard teaching strategy in the application of three-dimensional geometry, including fourbasic requirements, the four teaching improvement strategy; create a variety of mathematicssituation; stimulate the students’ desire for knowledge; Attach great importance to theconstruction, knowledge chart, graph; strengthen graphics language ability; Emphasize theequality and interaction between students and teachers, strengthen the emotional communication;pay attention to the design and construction of teaching resource database; promote teacher’steaching quality. Combining with the teaching strategy, auxiliary three-dimensional geometry teaching cases are given through electronic whiteboard in the classroom teaching and itsapplication is illustrated.According to the theoretical basis of the above, the author contrast experiment planformulation and implementation, to verify the feasibility and rationality of application strategy.The experimental results show that the experimental class students’ status and interests inlearning, classroom participation, knowledge, independent inquiry and spatial ability is superiorto the controlled class, thus it is concluded that the three-dimensional geometry teaching in theuse of electronic whiteboard optimization strategy can effectively develop the function ofinteractive electronic whiteboard, better integrate with classroom teaching. its use has strongerpracticability and rationality of the experiment conclusion.
