摘要：The completeness of interactive student networks are investigated in this paper, which can be used to improve middle school students’ independent environment for their study outside class. This paper takes covering approximation spaces as mathematical models of interactive student networks and characterizes completeness of interactive student networks by connectivity of covering approximation spaces. Further, this paper gives a simpler and practical method to check completeness of interactive student networks. Consequently, a way to communication among students is explored and applied in education.
