Abstract
In the "Internet Plus" era, teachers use Internet platforms and tools for knowledge management. The Internet has triggered 'knowledge explosion'. This phenomenon has brought a series of challenges to knowledge management, such as information overload, knowledge fragmentation, knowledge inertia and so on. In view of the above challenges, we should adopt the strategies, such as, establishing a knowledge database for teachers, giving offline knowledge management media a networked label information, creating a network atmosphere for knowledge sharing, and building a networked knowledge management environment, so as to promote the healthy development of "Internet plus education".
