Interoperability Between ELearning Systems

Online assessments are an integral part of eLearning systems that enhance both distance and continuous education. Although over two-hundred and fifty eLearning applications exist, most educational institutions are trapped with a particular vendor primarily due to lack of in test-question sharing features. This paper highlights the evolution of eLearning systems whilst detailing the two most prominent objective test question standards, namely, QML and QTI. An analysis conducted amongst software houses which are involved in the development of eLearning systems confirms the fact that most applications make use of proprietary formats and clearly shows a lack of import and export options amongst other features.
