Learning Visions: Ruth Clark: Evidence Based E-Learning #dl09 #dl09-104
Cammy Bean's live blogged notes from DevLearn with Ruth Clark. Lots of this is the multimedia principles I've read before (and maybe don't always apply in authentic learning environments, but that's another story). The research on animations vs stills was new to me though.
Could Power Point Presentations Be Stifling Learning?
This summary doesn't say how large the sample size was, and the researchers clarify that it's only about teaching new concepts. However, it is interesting to note that animation in PowerPoint slide decreased recall and comprehension.
<p>To test their hypothesis, the team recorded two versions of a PowerPoint lecture. The presentations differed only in the presence of animation to incrementally present information. They then showed students either the animated or non-animated lecture and then tested the students recall and comprehension of the lecture.</p>
<p>The team found a marked difference in average student performance, with those seeing the non-animated lecture performing much better in the tests than those who watched the animated lecture. Students were able to recall details of the static graphics much better. Animated slides meant to present information incrementally actually require greater concentration, which makes it harder to remember content as well as reducing overall exposure time to the "complete" slide, the researchers found.</p>

Top News - Analysis: How multimedia can improve learning
Research on how effective use of multimedia can improve learning outcomes. Based on research by Mayer, Moreno, Clark, & others. Much of this is in e-Learning and the Science of Instruction, but some of these principles, especially on interactivity, aren't included in that book. (Quotes from page 4)
Direct Manipulation Principle: As the complexity of the materials increases, the impact of direct manipulation (animation, pacing) of the learning materials on the transfer of knowledge also increases.
However, when the average student is engaged in higher-order thinking using multimedia in interactive situations, on average, that student's percentage ranking on higher-order or transfer skills increases by 32 percentile points over what the student would have accomplished with traditional learning.
