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...
Based on the summary of the teaching experience on “Computer Graphics”, this paper discusses the significance of visualization instruction and carries out the design and realization on visualization instruction of computer graphics algorithm. It includes generation of basic primitives, geometric transformations of these geometric objects, area filling, line clip and so on. At the same time the paper...
Course of algorithm is a specialized course of computer science with both strong abstract nature and practicality, for which needs of algorithm visualization technique in CAI is prominent. This paper develops a visualized CAI aiming at the characteristics of the course of algorithm, which provides users with the functions like responding, changing, constructing and presenting, conforming to the engagement...
Certain web behavior of community learning in web environment could explicitly or implicitly reflect to series learning characteristics, which can more or less response some learning attitude and effect. If learners attain the feedback of this information through virtual learning community by themselves easily and visually, it will be helpful to improve learning interest and method. Therefore, according...
There is no doubt that advanced mathematics plays an important role in computer-related professional teaching. Traditional advanced mathematics teaching trains a logical ideation of students in a good way; however, students are notable to experience it because of the non-convergence between teaching content and profession, and this reduces the enthusiasm of students. Therefore, with the requirements...
We analyzed the existing problems in teaching about programming design, and summarized the practical experience in teaching about programming design. We presented some reform methods, abstraction become instance, complex become simple, algorithm is more important than language, the students exercise is more important than teacher speak, and so on. Our methods can make student comprehension programming...
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...
