Richard Mayer and Ruth Clark are among the foremost researchers in the empirical testing of media and media mix hypotheses in online learning. Their e-Learning and the Science of Instruction (2003) covers seven design principles; multimedia, contiguity, modality, redundancy, coherence, personalisation, and practice opportunities. Clear explanations are given about the risks of ignoring these principles - with support from worked examples and case study challenges. It should be a compulsory text for online learning designers.
