摘　　要：培养与提高学生的空间想象能力是学好“机械制图”课程的关键。本文探讨了一系列有效的教学策略,包括运用直观形象的教学方法、强化二维视图与三维形体之间的相互转换、引入CAD软件进行三维几何建模、轴测图训练、机械零部件的测绘实践以及采用一题多解的启发式教学等。这些教学方法有助于全面培养学生的空间想象能力,降低课程的教学难度,激发学生的学习兴趣,发挥学生学习的积极性和主动性,从而提高学生的学习效果和教学质量。Cultivating and improving students'spatial imagination ability is key to mastering the course of"Mechanical Drawing".This paper explores a series of effective teaching strategies,including the use of intuitional and image teaching methods,strengthening the interconversion between two-dimensional views and three-dimensional shapes,introducing CAD software for three-dimensional geometric modeling,training in isometric drawing,surveying and mapping practice of mechanical parts,and the use of a multi-solution heuristic teaching.These teaching methods are helpful to comprehensively cultivate students'spatial imagination abilities,reduce the teaching difficulty of the curriculum,stimulate students'interest in learning,and bring out the enthusiasm and initiative in students'learning,thereby improving students'learning outcomes and teaching quality.
