Hi Jon,

Wow an insightful and very engaging presentation. It was able to clarify maths concepts. the excercises where focussed and related to the content. The one aspect of the presentation is that I found it a bit to wordy.

Technical Remarks:

i like to fomat of your presentation and liked the manner in which you used slide transition. The music also made it a bit more engaging. You had the buttons at the correct places and it was easy to navigate. Although I have to admit there were times when I dod not know where I was.

Used in course? Yes

This StAIR was very informative and visually attractive.  In particular, the music added a nice element to the presentation.  It would be very useful for students to use, but parents would also benefit from the tutorial especially as they help students with homework.  To improve the presentation you might consider,  allowing viewers more time to read through each slide or allow them total control so they can move to the next step when they're ready.  On the example slides adding audio describing the steps (particularly with the lattice slide and all the arrows) would also be helpful.

The presentation does not load from the MERLOT website.  I found the link on angel.  All bias aside, the presentation was ok.  I found myself unsure if I was supposed to click to go to the next slide or let the presentation automatically go to the next one.   The tables worked well for partial product method, however on the practice problem, I clicked one answer and they tried clicking another answer and it stated I was wrong.  (I am a math teacher)  The arrows on the lattice method also were a little confusing.  Possibly load each arrow one at a time so a student can see the process.  I also had problems with that practice problem as well and was not sure if i reached the end of the presentation or not.  With some tweaking and some different animations, I think this could be a really strong resource

Technical Remarks:

Timing versus clicking, some links in the practice weren't working correctly.  Adding some directions for the learner

The presentation of the material is very nice.  And, the music is a great element of the module.  The explanations and interactive portions were informative and easy to use.

Some of the slides moved faster than could be read aloud.  I think it would be beneficial to the user if the user could control the pace of the slides in case a person needs to read the presented information more than once, or needs to read it slowly, or aloud. 

Other than that, the module seems very useful, informative and fun to use.

Technical Remarks:

All pages, arrows, and functions seemed to work the way they were intended.
