Things Done Well:

Nice use of many different quadratic examples!  

It is great if the students get the questions incorrect that you show them how to 'start' the problem, and continue the answer further, if they need more assistance.

Nice use of the fading in of examples, along with the timing of the next button, so the students could not skip over the examples.

Things that could be added/corrected:

I think that it would have been nice if the video was embedded in the StAIR (but I was also having problems doing this!)

It would have incorporated more UDL requirements if it had had some voice over some where throughout the presentation.

The you trys were a little confusing because they didn't actually have you "try" you watch the example but then they had examples later for you to "try"

 

Technical Remarks:

Nice use of power point kiosk!  

Some the links were not visible if I had made a "mistake" on the questions (the answers were not visible on all of the links)

Strengths

Good examples and textual explanations of the concept.

Strong instructional scaffolding.

Provided user feedback when links were present and functioning.

Weeknesses

What should the students be looking for in the video?

Does not meet UDL principles for most of the lesson. A voiceover of instructions and explanations woud improve this lesson. A sort video of the teacher explaining the concept would help as well.

Practical example using this concept would provide context.

Technical Remarks:

Overlapping text on some slides is difficult to read.

Multiple broken links throughout the presentation.

Embedding the video in the presentation would streamline the lesson.
