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.
