A Broker Based E-learning Service Integration and Execution Architecture for the Complex Requirements on Learning Resources

The rapid growth of acquisition, application and dissemination of knowledge facilitated by electronic means lays an urge for concrete e-learning model. The increasing demand for seamless accessibility, reusability, aggregation and effective execution of learning activities explored a numerous research issues. This paper proposes a mashup with integration mechanism for e-learning. To realize integration, the authors propose a semi-dynamic e-learning service composition which uses predefined functional and flow descriptions. The mashup broker integrates the functionalities of multiple, dynamically discovered e-learning services into a single service based on the learner´s requirements. The execution order of composed activities is determined from e-learning activity flow descriptions. The requested learning activities are delivered to the learner in computed sequence as a single learning service. The proof of concept experimentation shows that, the broker architecture for e-learning facilitates effective access and aggregation e-learning services/resources.
