e-Learning Chapter 3 APPLYING THE MULTIMEDIA PRINCIPLE: USE WORDS AND GRAPHICS RATHER THAN WORDS ALONE Things to Remember MAT 611 Candace Brown and LuAnn Phillips
Learning increases when words are combined with multimedia
Static illustrations- maps ,drawings, photos
Dynamic graphics – animation, video
The following slides have graphics representing a fictional how-to for knitting.
Use graphics NOT as decorations but as information enhancers
6 Types of Enhancement Graphics
concepts and their part
K1, P1 Ribbing Knit all rows - the Garter Stitch Knit 1 row, Purl 1 row- the stockinet stitch
used to illustrate content that is difficult to convey using static images
show relationships among ideas or topics
show relationship between a whole and its parts
Use to show quantitative relationships among variables
These 2 charts show the growth of Ravelry:
This is text reporting the incredible growth of a knitting social forum called, Ravelry: “ We’ve got 430,000 registered users, in a month we’ll see 200,000 of those, about 135,000 in a week and about 70,000 in a day. We peak at 3.6 million pageviews per day. That’s registered users only (doesn’t include the very few pages that are Google accessible) and does not include the usual API calls, RSS feeds, AJAX. Actual requests that hit Rails per day is 10 million. 900 new users sign up per day. The forums are very active with about 50,000 new posts being written each day. Some various numbers — 2.3 million knitting/crochet projects, 19 million forum posts, 13 million private messages, 8 million photos (the majority are hosted by Flickr).” Which conveys the information in amore efficient manner?

Summary: Applying the Multimedia Principle
Research shows that people learn more deeply from words and graphics than words alone.
Choosing the appropriate media for the lesson is essential.
Animation sometimes causes cognitive load or fosters passive learning.
Novices benefit most from multimedia lessons.
Unknowns: impact of visuals on long-term learning, how quality of the visuals affect learning, when an animation is better than a static, and how to determine the cost benefit of investment in media.
