基于Flash3D 技术的小学立体几何教学平台的设计与实现

Design and Implementation of Elementary School Solid Geomery Teaching Platform Based on the Flash3D Technology

空间观念的培养是小学数学课程的重要目标之一。当前的教学过程中缺少可以操作的可视化学习工具，难以满足立体几何的教学需求，根据这一问题设计并实现了小学立体几何教学平台。文章阐述了该平台的设计理念、主要功能和系统架构，引进了新兴的Flash3D 技术，并对著名的Flash3D 引擎——Alternativa3D 的开发流程进行了详细介绍，基于该引擎对平台进行实现。平台具有逼真的三维场景、丰富的感性资源、友好的交互方式等特点，是新技术在教学中应用的一次有益尝试。

The cultivation of space concept is one of the most important teaching objectives of mathematics curriculum in elementary school. Because of lacking visual operable learning tools, the current teaching process can’t meet the teaching demand in solid geometry. According to this problem, the article designed and implemented the Elementary School Solid Geomery Teaching Platform. This article elaborated the design philosophy, main functions and system framework of the platform, introduced the new emerging Flash3D technology, and explained the develop process of Alternativa3D in detail, which is a most popular Flash3D Engine and the base of platform. The platform has several features such as: realistic three-dimensional scene, rich perceptual resources, friendly interactive mode, etc. It is a successful attempt that applying new technology in teaching.
