Evaluating the Educational Influence of an E-Learning System

Nowadays educational systems present their users (teachers and students) an intelligent environment in order to enhance the learning and teaching process. The goal of e-learning system developers is to build such systems that will create individualized instruction to get as close as possible to the 2-sigma boundary. Because of the fact that acquisition of knowledge is often an expensive and time-consuming process, it is important to know whether it actually improves student performance. In this paper we are going to present our approach about evaluating the educational influence of a e-learning system as well as some results on the evaluation of the e-learning system educational effectiveness in augmenting student's accomplishments for a particular knowledge domain by using the effect size as the metrics. By doing so, we determine whether and in which degree an e-learning system increases student’ s performance and can, therefore, be an adequate alternative for human tutors.
