中职机械CAD迁移学习法应用探析

Analysis on the Application of Transfer learning Method in Mechanical CAD of Secondary Vocational School

机械制图是机械专业,乃至建筑、土木等其它专业的入门课,是表达实际工程的语言。熟练掌握CAD软件已经成为各行业需要的必备技能之一,笔者在教学过程中发现,传统的教学模式已不能适应中职学生的学习现状。为解决这一问题,提高学生的绘图技能,在教学中引入迁移学习法,利用学生已掌握的基础知识提升CAD的绘图能力。迁移学习法不但能把新旧知识联系起来,而且能够让学生掌握绘图技巧,学会思考如何绘图,在实践中提升专业技能。

Mechanical drawing is an introductory course for mechanical majors,even architecture,civil engineering and other majors.It is the language of expressing actual engineering.Proficiency in CAD software has become one of the necessary skills required by various industries.The author found in the teaching process that the traditional teaching mode can not adapt to the learning status of secondary vocational students.In order to solve this problem and improve students'drawing skills,the transfer learning method is introduced into the teaching,and the basic knowledge that students have mastered is used to improve the drawing ability of CAD.The transfer learning method can not only connect the old and new knowledge,but also enable students to master the drawing skills,learn to think about how to draw,and improve their professional skills in practice.
