Scaffolding environment for e-learning through cloud computing

This paper presents a new approach to the integration of web services for e-learning through cloud computing infrastructure. The primary goal is to improve the performance of the existing e-learning system where group adaptation is applied. The proposed method includes an integration of information, processes, applications and human resources in the e-learning system. Integration is based on a web application we developed for managing the learning environment. The application enables an integration of the Moodle, the OpenLDAP directory for managing user accounts, and the OpenNebula toolkit for managing a cloud computing infrastructure. The major advantage of the suggested approach is that the existing system for adaptive e-learning does not need any changes, while it becomes more available and suitable for ubiquitous learning. We evaluated the implemented environment in an undergraduate course at the E-Business Lab, University of Belgrade.
