Multimedia tools improve our brain's memory power.

It's been proven through multiple research studies and surveys that multimedia in eLearning, such as images and video, not only engage the learners but also help them to actually remember what they've learned. Research cited in a report by Michelle Chau cites a number of examples of how interactive learning tools, such as ebooks, lead to improved knowledge retention [3]. According to research, students who used ebooks that contained sound effects, music, audio narration, and images were able to retain and recite more information than those who were simply given traditional textbooks. Utilizing these ebooks also led to group collaboration and peer interaction, as the students did not have to sit quietly on their own and privately read the text. This is yet another example of how using multimedia elements can enhance an eLearning course and provide the end user with an improved educational experience.
