Abstract: In the 21st century, under the requirements of higher education to train innovative talents and great craftsmen, the teaching concept and teaching mode of split classes are introduced into modern engineering drawing, and the specific implementation process of the three steps of the sub mode (internalization absorption, group discussion, teaching new knowledge) is explained. The practice shows that the teaching effect of the split teaching mode is better than the traditional teaching class, it can stimulate the subjectivity and enthusiasm of the students' learning, and the simultaneous class is more suitable for the students to learn modern engineering drawing. This interactive discussion type is more suitable for the students to study modern engineering drawing in our school learning is more conducive to improving the quality of teaching.

Key words: Split classroom, Engineering cartography, Teaching mode independent, Learning internalization
