Multimedia Learning Theory
1. 2 channels
2. Limited working memory
3. Knowledge construction
Dual Coding – Paivio (verbal & image – cross links)
Linked, but stored differently - illustrated by the experience of peopl who develop aphasia.
What about the blind? How does this verbal/visual connection work with people who have no vision? (And who never had vision in the first place.)
What about kinesthetic aspects to learning? Dancer, athlete, ASL "speaker"? Is this comparable to the visual and verbal channels?
(See: embodied cognition - here's an article from the Boston Globe on this concept.)

John mentioned Kintsch and his text model. (Author of "Comprehension: A Paradigm for Cognition.")
Here’s a quote I found:
Van Dijk and Kintsch (1983) developed one of the most influential theories on reading comprehension. Their theory describes the whole reading process, from recognising individual words all the way through to representing the meaning of a whole text. According to their model, the process of comprehension has three phases: a verbatim representation, a semantic representation, and a situational representation. (link)================

John spoke about the Flint effect? What is this? (Natalie Flindt?)
G – human processing ability.
(I couldn't find anything on this concept)
Tom mentioned Edward Tufte – powerpoint rules – Here's an article from Wired: "Powerpoint is Evil". After reading it, I think Tufte may not understand the way PPT should/could be used by students. Here's a more effective article on "Powerpointlessness" on the FNO.org site. (And here's another!)
