Designer skills should include knowledge of using video, audio, AR, VR still images, animation and anything else that can help maximize learning and gain benefits. Richard Mayer, Professor of Psychology at the University of California, Santa Barbara, has spent years researching how to use multimedia to maximize learning. Together these principles and prerequisites are part of Mayer’s “cognitive theory of multimedia learning. The first key is to remember that the effective use of multimedia in e-learning involves more than creating videos, creating PowerPoint presentations or producing animations and integrating them seamlessly into classrooms written for publication on the Internet. If the principles are not embedded in the design, no matter how amazing the multimedia material is, the efforts and money are wasted if the final result gets in the way and the users do not learn. Digital technology has brought many benefits to users who want or need to acquire new skills and knowledge. The assumption of active processing means that people have to be involved in active cognitive processes in order to learn, as opposed to the “knowledge dumping” of the education approach in which students are passive.
