Abstract: This paper introduces a method of introducing all-around opening labs to the class teaching
of engineering drawing, and many practicing instances are given. This teaching mode is based on
students’ self-lab-management, case-driven micro lecture learning, and the combination of class
teaching and opening lab practicing. It has been successfully run for more than 3 years, and large
quantity of excellent students’ works have been accomplished, which proves that it is very effective to
improve student’ s learning interests, practicing ability and innovation consciousness. This mode is
replicable.

Key words: all-around opening labs, engineering drawing, 3D print, numerical control, microlecture
