Abstract: This article takes the mechanical design course group as the research object, systematically reshapes the teaching environment, teaching resources, and teaching subjects involved in the mechanical design course group, proposes an innovative professional training plan, builds an online and offline collaborative application teaching platform, formulates a digital collaborative teaching plan, studies the use of online teaching platforms, MOOC platforms, smart education platforms and other resources, and adopts digital network technology, virtual technology and other means to construct a multi scenario collaborative teaching mode. This mode provides a good demonstration and leading role for the construction of engineering subject courses.

Key words: Digital technology, Multiple scenarios, Coordination, Teaching system, Teaching mode, Design course group
