E-Learning Computational Cloud (eLC2): Web Services Platform to Enhance Task Collaboration

摘要

A significant proportion of e-Learning services are delivered through Cloud Computing. These use Web services as an interface integrator to support communication across heterogeneous platforms over internet protocols. Similarly, a high level of task collaboration is needed to form an e-Learning community. Therefore, we propose an e-Learning Computational Cloud (eLC2) based on the Model-View-Controller design patterns paradigm. The reusable task objects collaborate in a Model that is wrapped inside the reconfigurable Controller which transforms the request/response parameters of the end user View to that of the Model. The eLC2 offers software development platform for e-Learning Task Management. The main deliverable of eLC2 is a Task as a Service which is decoupled from View as well as user session maintenance. It is directly exposed to external the e-Learning Cloud for scalability.
