The coherence principle states that people learn better when extraneous material is excluded. Mayer stated that learning "is improved when interesting but irrelevant words and pictures are excluded from multimedia presentation" (2009, p.89). This idea behind this is that this extraneous material competes for the learners cognitive processing and diverts attention from the intended material. Lets listen to this brief video on the coherence principle.
I totally agree! I hate it when I am watching a presentation and there is a ton of extra pictures and unnecessary material. It is hard to focus on what is the intended focus in those instances.
ReplyDeleteThis video was very helpful. It explained the principle well and gave excellent examples. I also appreciate the questions encourage interaction.
