交互式电子白板在工程图学教学中的应用

Application of Interactive Electronic Whiteboard in Engineering Graphics Teaching

本文分析了工程图学所采用的主要教学方式,针对各种教学方式的特点,主张引入交互式电子白板(IEWB)辅助工程图学教学。交互式电子白板辅助教学可实现在白板上画图的示范教学,既高效又实用。本文还举例分析了交互式电子白板在立体投影、组合体三视图、剖视图、零部件等方面辅助教学的技巧与方法,并介绍了一些功能的应用。交互式电子白板的应用集合了板书、多媒体和计算机绘图的综合优势,同时大大减少了教师课前准备的工作量,有效地将抽象的空间思维过程直观化、具体化,更加方便学生接受学习内容,强化了学生使用绘图工具的技能,极大地提升了教学效果。

This paper analysed the main teaching methods used in the teaching of engineering graphics,and put forward the introduction of interactive electronic whiteboard(IEWB)aimed at engineering graphics teaching in view of the characteristics of various teaching methods.Teacher can plot graphs on interactive whiteboard and realize the demonstration teaching which is efficient and practical.The techniques and methods of application of IEWB are analyzed in the aspects of stereographic projection,three view of composite body,section view,parts and other aspects.Some useful functional applications were introduced to be applied in teaching.IEWB had the comprehensive advantages of blackboard,multimedia and computer drawing.At the same time,it greatly reduced the workload of preparation before class for teachers,and effectively visualized and concretized the abstract space thinking.So it was more convenient for students to accept learning content.Skills in the use of drawing tools for students were enhanced.Finally,the teaching effect was greatly improved.
