Cultivating spatial imagination in mechanical drawing teaching under CDIO mode
Aiming at the problems such as short middle school teaching time,poor spatial imagination of students,and unim-proved self-learning ability of mechanical drawing course,this paper proposes advanced ways to improve students′spatial imagina-tion,expounds the general process of line and surface analysis,and summarizes the process of two-way conception,design,realization and operation of teachers′topic design and students′spatial imagination cultivation under the CDIO mode.It provides reference for stimulating students′interest in learning and improving teaching quality in mechanical drawing teaching.
