基于目标导向的联想教学法在工程制图课程教学中的应用与研究

Applying Goal-oriented Association Teaching to Engineering Graphics Course

工程制图课程是工科类的一门重要的专业基础课,部分学生由于空间想象能力稍差,不能够准确想象出形体的空间形状,进而影响投影图形的绘制。基于目标导向的联想教学法是引导学生以形体的真实形状为目标,应用常见的生活工具加上合理的引申联想,帮助其有目的、有导向地想象空间形体形状及其投影,提高学生空间想象能力的一种教学方法。通过利用不同的生活工具模拟不同的基本形体,详细讲解了工程制图课程中的一般及特殊位置点、线、面以及立体的截切、相贯的空间形状及其投影特性,阐述了联想教学法在课堂教学中的应用。

Engineering Graphics is an important basic engineering course for engineering specialty, but some students are not good at accurately visualizing the shapes of objects due to their poor spatial congnition, which can thus affect their drawings. The goal-oriented association teaching method uses tools in daily life and reasonable association to help improve the students＇ spatial imagination. Using different tools to simulate different shapes, the spatial shapes and projection properties of general and special points, lines, surfaces, and cutting and intersecting of objects in engineering drawing can be explained and learned very well in detail.
