The Design And Development Of The Three-view Dynamic Multimedia Courseware For Straight Prism

This paper mainly recorded the teaching process of the three views of Right Prism,which is the second lesson of Projection and Views,the fifth chapter of ninth grade mathematic bookl published by Beijing Normal University.In the teaching process,I found that the three views of Right Prism must be showed by the Dynamic Multimedia Courseware,which is studied and designed by very few people.After comparing a number of geometric drawing software,such as Geometer's Sketchpad,Geometric Map,Math3D,Super Sketchpad,finally I chose CAD to design the dynamic courseware of three views.And this text mainly discusses the significance and method of designing and developing the dynamic courseware of three views in the class,and how to make use of the dynamic courseware to help students break through the teaching difficulties of this class is analyzed emphatically.This paper is to record my experience in teaching this class,hoping that I can maintain the spirit of exploration in the future teaching,and constantly improve my teaching quality.This paper introduces the research background of this class.because the examination requirements of three views in senior high school entrance examination are relatively simple,there are very few teaching research on three views in junior high school in China.A few articles mainly explain theoretically the importance of attaching importance to three-view teaching in junior high school.Based on this research situation,I made many modifications to the teaching design for this class,and finally determined the main methods of using dynamic multimedia courseware to assist teaching,and selected auto CAD to make dynamic multimedia courseware,and started the research process of courseware design for this class.At first,I recorded the process of learning how to make simple geometry by CAD,expounded the advantages of CAD in making stereo graphics,and recorded in detail every step of making dynamic courseware by using this software.Secondly,after many times of class practice and modification of teaching design,I formed a clear process of taking this class myself,gave my teaching design of this class,and recorded my teaching reflection after practice.Finally,after this research process,I decided to further promote the knowledge and methods gained in this research.For example,auto CAD files produced by ourselves are recorded into a micro-class to show the dynamic process of three-view formation,so that more people can attach importance to the teaching of this class,and more students can see the formation process of more intuitive three-view when learning this class,thus helping students break through the learning difficulties of this class.Later,I will record my basic method of making three views of simple geometry with CAD into a video for others to learn,so that more teachers can make three views of geometry with different shapes with CAD when teaching this class,which will provide greater convenience for students to learn.Although the requirements of the senior high school entrance examination outline of the three-view section of the straight prism are simple,in order to better cultivate students'spatial imagination and lay the foundation for students to learn solid geometry in high school,there are still many places worth thinking and studying in teaching.I hope that I can take this study as a starting point,and more research can be done on how to better cultivate students' interest in learning mathematics,how to cultivate students' interest in geometric learning,how to permeate and cultivate students' spatial ability in specific teaching cases,and how to better apply intuitive teaching modes such as physical model and design and development of dynamic courseware to ordinary teaching.
