工程制图一直被认为是一门实践性学科,其整合了几何学、建筑、力学、电子制图等,从而将理论与现实图像联系起来,工程制图能为每个不同形状、尺寸的物体提供精确的、完整的图像。通常,即使在开放与远程教育环境中,工程制图的教学也是通过面对面的教学模式来进行的。由于其特殊性,一些学习者可能难以想象并解释这些图像。然而,尖端的技术使得可以通过在线的方式加强工程制图的学习。研究者基于建构主义模式开发了一个面向工程制图教学和学习的网络系统。该系统适用于几种工程制图,例如展开图、刻面图、等角图和斜角图。学习过程包括导论、概念学习、工程制图方法,以及应用与练习等阶段。在导论阶段,系统为学习者提供了专题简介,然后是概念学习阶段。系统所提供的学习环境允许工程专业的学生从三维透视、一维透视、平面图、侧立面、正立面等不同角度来观察物体。经过概念学习阶段后,系统将引导学生通过动画和模拟学习每个专题中制图方法的不同步骤,学习者也能重复观察任何剖面。另外,还通过图像、动画和视频等方式展示真实的工程制图应用案例。最后,为了评价学生的理解能力,在每部分内容后面都附有相关的练习。
Engineering drawing has long been considered a practical discipline that integrates geometry, architecture, mechanics, electronic mapping, etc., to link theoretical and real-world images, and engineering drawings can provide accurate, accurate results for each object of different shapes and sizes , Complete image. Often, even in the open and distance education environment, engineering drawing is taught through face-to-face teaching. Due to their special nature, some learners may find it difficult to visualize and interpret these images. However, state-of-the-art technology has made it possible to enhance the engineering drafting learning online. Based on the constructivist model, the researchers developed a network system for engineering drawing teaching and learning. The system is suitable for several engineering drawings such as unrolled, faceted, isometric and bevelled drawings. The learning process includes introduction, concept learning, engineering drawing methods, and application and practice phases. In the introductory phase, the system provides the learner with a feature profile, followed by a concept learning stage. The system provides a learning environment that allows engineering students to observe objects from three perspectives, one-dimensional perspectives, floor plans, side façades, and façades. After the concept learning phase, the system will guide students through animation and simulation to learn the different steps of the drawing method in each topic, and learners can observe any profile repeatedly. In addition, through the images, animations and videos showcase the real case of engineering drawing applications. Finally, in order to assess the students’ understanding ability, relevant exercises are attached after each part content.
