Mayer's Temporal Contiguity Principle

This video explains Dr. Richard E. Mayer's Temporal Contiguity Principle, one of his Multimedia Design Principles for designing more effective learning experiences. You've probably heard the saying "timing is everything". Well, in the case of the Temporal Contiguity Principle, it really is everything. Dr. Mayer's research found that people learn more effectively when voice-over related to the visuals is presented simultaneously rather than after the visuals appear. Remember to "show AND tell", not "show THEN tell". Expert Tip: This principle may seem pretty obvious, but it's surprising how often designers don't get this quite right. It's not only important to make sure that the voice-over narration is synchronized to the visuals on-screen, it's also important to be super accurate with the timings of things, especially when there's a lot going on. In some cases, the timing being off just by a fraction of a second can cause cognitive overload for your leaners. Mayer's Principles for Reducing Extraneous Processing This is one of Dr. Mayer's principles related to the instructional goal of "reducing extraneous processing" for your learners when designing multimedia learning experiences. The goal here is to lessen the cognitive load placed on the learner's brain by reducing the non-essential information as much as possible. Basically this boils down to getting rid of stuff that isn't crucial or relevant to the learning objectives at hand. The non-essential information just ends up being a distraction to the learner. We need to make sure that the learner can focus on what they should be paying attention to.
