Massive Open Online Courses (MOOCs) are growing substantially in numbers, and also in interest from the educational community. MOOCs are online courses aimed at large-scale interactive participation and open access via the Web that made them possible for anyone with an internet connection to enroll in free, university level courses. In this paper, we propose a novel method to discover various types...
According to the classification principles of educational information in LOM, and the characteristics of grid community and resource distribution in grid, on the basis of a proposed model of grid community based education resource, the brief paper puts forward constructing the concept of Equivalent grid community group, building the mechanism of resources-sharing and information-spreading between...
The minimum spanning tree(MST) of a graph defines the cheapest subset of edges that keeps the graph in one connected component which is a classic problem in operational research(OR) with important applications in a number of applications, both as a stand-alone problem and as a subproblem in a more complex. The problem considered here is that of determining whether a given spanning tree of a graph...
In recent years, due to large amounts of network-based teaching and learning data continue to grow inexorably in size and complexity, knowledge clustering becomes more important in e-learning. This paper proposes a novel algorithm of cluster analysis to extract clusters in dense sub- spaces and the clusters can be described by overlapping hierarchical concepts. The experimental results show the algorithm...
