“机械制图”是开放远程教育数控专业的一门专业基础课程。该课程的教学方法和教学效果将直接影响学生的专业素质。但近年来,学生期末考试通过率较低,特别是浙江省很多教学点合格率甚至不到20%,学生往往因为该课程耽误了毕业时间,因此如何调动学生的学习积极性和主观能动性,如何根据开放远程教育的专业培养目标、生源基础和学校现有教学技术,运用有效的策略,激发学生学习兴趣,是摆在我们面前的一项亟待解决的课题。 “Mechanical Drawing ” is a professional basic course of open distance education numerical control major. The course teaching methods and teaching effectiveness will directly affect the professional quality of students. However, in recent years, the passing rate of students in the final examination is low, especially in many teaching points in Zhejiang Province, the passing rate is even less than 20%. Students tend to delay the graduation time because of the course. Therefore, how to mobilize the enthusiasm and subjective initiative of students? The open training objectives of distance education, the foundation of students and the existing teaching technology in schools, and the effective strategies to stimulate students’ interest in learning are a pressing issue before us.
