Instructional Design Principles

Overview
Multimedia Principle (3:26)
Description
The multimedia principle, as set out by Richard Mayer in 2001, recommends that e-learning courses include words and graphics, as opposed to just words. Based on cognitive theory and research evidence, learners are more likely to understand material when they can actively engage with it. Multimedia presentations can encourage learners to engage in active learning by mentally representing the material in words and in pictures and by making connections between the pictorial and verbal representations.
Guidelines for Use
Guideline 1 – Pictures Should Not be an Afterthought
Pictures should not be an afterthought. Instead of selecting pictures after the words are written, instructional designers should consider how words and pictures work together to create meaning for the learner. Therefore, visuals as well as words should be planned together as the job analysis is conducted and the course is designed.
Guideline 2 – Selecting the Appropriate Combination of Content and Graphics
Depending on the type of information you plan to present, selecting the appropriate combination of content and graphic types is essential to creating material that fosters active learning. See table below for examples:
