【摘要】结合本校实际情况介绍虚拟教学平台的结构功能,针对当代大学生的特点和机械制图课程教学中遇到的问题,提出研究性教学改革设计方案,将计算机绘图与机械制图课程相结合,基于CAD虚拟三维环境开展体验式教学,使学生在学习操作SolidWorks软件的同时,逐渐培养空间想象力,形成由三维实体到二维平面图相互转换的思维能力,同时结合CAI课件以及Bb平台教学平台资源,举例说明各重点章节的教学方法,以实现学生从教促学方式向自主学习方式的转变,发展学生的自我探究意识与构思创想能力。

【Abstract】This paper described the structure and function of the virtual teaching platform with combined with the actual situation. The design of research teaching was proposed for the characteristics for the college students and the problem appeared in the mechanical drawing class. The combination of computer aided design and mechanical drawing course was implemented. The experiential teaching based on virtual 3D environment with CAD was present in order to achieve the change from the way of promoted learning to the way of self-learning. The student will gradually develop the imagination space by learning how to operate the software SoildWorks, and forming ability of conversion from 3D to 2D with combining with the CAI courseware and Bb teaching platform. These changes will help to develop the students abilities of self-inquiry conscious and creative idea.

一、引言

机械制图是一门着重培养学习者空间思维能力和构思创想能力的课程,同时也是一门实践性非常强的重要专业基础课程。学习这门课程对学生的空间认知能力、想象力、绘图能力都有较高的要求[1-2]。但实际教学中发现,很多学生形成三维空间想象力很困难,单纯使用讲授不利于学生对知识的消化和吸收,即使采用现代教学演示方法,如多媒体教学等,其效果并不显著。

故作者认为,基于虚拟教学平台在三维虚拟学习环境中进行体验式教学应该是一种不错的尝试,将讲授控制在必要的范围之内,利用有限的教学时间让学生由被动学习变为主动学习,鼓励学生独立解决问题,真正参与到课堂互动中来,可有效地提高学生的认知水平,发展学生的探究意识与能力。……
