A Generic E-Assessment Process Development Based on Reverse Engineering and Cloud Services

摘要

Nowadays, there are many problems related to the e-learning in the development of E-assessment such as the difficulty to use the assessment object from a platform to another one. As the domain model reuse rate is very low in various e-learning systems and hardness to guarantee the consistency between designs and codes. Therefore, we need an approach aiming to generate a general process of the e-assessment. The present study describes an approach for integrating e-assessment functionalities of learning management systems (LMS) candidates into a generalized e-assessment process. To attempt these goals, we have studied different existing LMSs to depict their various e-assessment activities from which we have generated a set of generic e-assessment activities using the reverse engineering. Then, we have integrated these activities into a workflow model to specify a generic e-assessment process based on pedagogical scenarios. We have defined these scenarios using workflow to provide an abstract e-assessment process. Finally, we have implemented this generic e-assessment workflow as a cloud computing service to be invoked from any LMS.
