This StAIR has a good visual layout, and the way it presents information is clear. However, the use of powerpoint animation was problematic (except in one way, noted below). Animations that roll out text assume the student is reading at a particular speed. I found this very distracting while I was taking in the core information being offered. The same issue exists when the lecture is revealing sample problems and answers (such as the graphs). The problem or answer was either being revealed too quickly, or I was waiting for it. If text or problems need to be revealed on the same slide, I would like to be told "click to continue", and have the text, problem, or graph revealed.
The quiz had a functionality issue where it was unclear where to click to select an answer. This may be a powerpoint-specific issue. I would recommend putting the clickable buttons separate from the answers (they were laid under the answers, which may have caused the problem). In its current form (6/24/2012), there were only small slivers of clickable space.
The one area I thought the reveal animations really did work to benefit the material was on a new slide revealing a new quiz question.
The quiz questions offer good feedback for wrong answers. One had a link to a Khan Academy video, I would recommend linking more feedback to such relevant videos for reinforcement/remediation if they exist.
The lecture portion could benefit from an audio reading of the text, as per UDL.
Overall, well done. After some tweaking, this will be an extremely solid and useful resource!
