“computer network course” is an important basic course for science and engineering students, with
strong theory, many knowledge points and wide coverage. How to improve the teaching quality of the course is
a widely concerned problem. Based on the existing teaching resources, following the education concept of OBE
(taking students as the main body and taking the development of students as the standard), we designed and
implemented the hybrid teaching mode, and focused on the construction of “efficient classroom”. The teaching
practice shows that the mixed teaching mode is conducive to promote the Cadets’ autonomous learning and the
cultivation of their practical ability and innovative thinking ability.
