At present, enterprises need a large number of high-quality talents with professional and technical skills. As teachers who teaches computer courses in vocational colleges, we developed and applied the The Practical Training Manual on Computer Network Courses based on the demand of enterprise positions for the students majoring in computer network and enterprise post practice learning.The development of The Practical Training Manual enables teachers under the background of the network to effectively use online + offline teaching resources as a way to realize the expansion of teaching resources, so that students can complete the learning tasks in the future learning. By doing so, we stimulate students interest in learning, meet the demand for enterprise positions, and realize the depth of integration between schools and enterprises in a true way, to achieve the goal of improving the quality of teaching.
