摘　　要：机械基础课程理论性强,抽象概念多,相关理论的逻辑性也比较强,学生普遍对该课程中铰链四杆机构急回特性部分内容的学习存在较大困难。高职高专的学生通常学习基础薄弱、学习动力不足、逻辑思维能力较差,但由于动手能力较强,所以比较乐于学习实用性较强的技能。针对高职高专学生的这种特点,在教学中不仅可以采用任务驱动式的教学方法,而且可以结合学生认为比较实用的制图软件Auto CAD来布置学习任务。通过实际动手操作,既能够加深学生对概念的理解和认识,同时又可以提升学生的制图软件运用能力,从而激发学生的学习兴趣,提升学生的探究能力。The course of mechanical foundation is theoretical, abstract and logical, so it is difficult for students to learn the quick return characteristics of hinged four-bar mechanism. The vocational college students usually have weak learning foundation, insufficient learning motivation and poor logical thinking ability, but they are more willing to learn practical skills because of their strong practical ability. In view of the characteristics of higher vocational college students, we can not only use the task driven teaching method, but also arrange the learning tasks in combination with the practical drawing software Auto CAD. Through practical operation, it can not only deepen students’ understanding of the concept, but also improve students’ ability to use the drawing software, so as to stimulate students’ interest in learning and en-hance students’ exploration ability.
