The Study On Instructional Strategy In Primary School Mathematics "Graphics And Geometry" With The Interactive Electronic Whiteboard

With the development of the information of basic education, interactive electronic whiteboard as a new kind of teaching media has been widely introduced in primary and middle school classroom. It’s strong interaction, integration and visualization of the operation, overcome the difficulties of traditional multimedia about "preset more, generate less" "demo more, interaction less" "media more, resources less", and build a new teaching environment of "take the student as the center, interaction as the core”, it has become a kind of development trend of classroom teaching."Graphics and geometry" as an important part of the primary school mathematics, the abstractness is stronger. How to use the advantage function of the interactive electronic whiteboard to help students better understand and use graphics and geometry knowledge, cultivate the students’ space concept, geometric intuitive, innovative consciousness and ability to solve practical problems, is the focus of this study.This article adopted the method of literature review and video analysis. It is concluded that the advantages and disadvantages of interactive electronic whiteboard in the primary school mathematics classroom instruction application. And put forward the purpose and significance of this study. At the same time, it laid a theoretical and practical basis for the instructional strategy of "graphics and geometry" in the primary school mathematics based on the interactive electronic whiteboard. Under the support of relevant theories, in-depth analysis of graphics and geometric instructional contents and objectives, according to the instructional objectives, starting from the way of students easy access to knowledge, the instructional contents of "graphics and geometry" is divided into three categories: observation, operation and imagination. And in view of the different types of instructional contents, follow the principle of interactive electronic whiteboard and mathematics curriculum integration, and combined with the current primary school mathematics "Graphics and Geometry" problems existing in the teaching and the characteristics of learners, puts forward the corresponding instructional strategies: direct instructional strategy, interactive instructional strategy and the situation instructional strategy, and turn it into Instructional practice. After two stages of practice and revision in a semester, with the method of interview and questionnaire survey to test the teaching effect, and finally validated the effectiveness of the strategy. The innovation of this research lies in the innovation of the practical significance of instructional strategy.
