E-books and e-learning are becoming recurrent tools in the academic landscape. One of the key characteristics of e-learning is its capability to integrate different media, such as text, picture, audio, animation and video to create multimedia instructional material. Media selection in e-learning can be a critical issue because of the increased costs of developing non-textual e-learning materials. Learners can benefit from the use of richer media in courses that contain equivocal and complex content; however, learners achieve no significant benefit in either learner score or learner satisfaction from the use of richer media in courses containing low equivocal (numeric) content.
