Chris+O.

For Chris O.

1. Objective: Review why the point/slope form of the equation of a line works. 2. Video URL: http://www.youtube.com/watch?v=5Kuv5KYJZM8&feature=plcp 3. Why did you make the video the way you did? I wanted to test drive features of ExplaneEverything. 4. What are some other ways you could have presented the material using video? More primitive (i.e., captured chalk talk)

Peer Reactions:

I think you realized how to "pointilize" (if that's a word) your stylus a bit more as you moved through different examples. Much more effective. The thickness allows you to occupy less screen space and it's a bit less overwhelming.

Andrea: I think it was a nice job teaching, but that your objective as stated above maybe wasn't your real objective. From watching the video it seemed like your objective was to show how to find the equation of a line given a point and the slope...and perhaps also to review what slope means about a line. You were very clear. Your explanations were not too wordy. I agree with the above person's point about the stylus. And just fyi there was a small slope mistake on your very first example...you put a zero in instead of a one. Just wanted you to know if you used it in class in the future.

nicely done- good use of graphics, and markups. I especially liked the birds in the background! Your voice sounded fine; good pacing. Dick

1. Objective: Show how to use registers and lists on the TI-84. 2. Video URL: http://www.youtube.com/watch?v=0ioL7QAxHhI&feature=plcp

3. Why did you make the video the way you did? Out of time--had to get something recorded quickly. 4. What are some other ways you could have presented the material using video? Less primitive!!

Peer Reactions: Andrea: Hi Chris - I learned about the list and the variables in y= mode. Cool. never knew that. I liked this one a lot. I suspect you were limited by equipment, but it was a little bumpy and I was a bit distracted by the grass on the right. But those are little things. The lesson was good.

great use of the metal device- how else to easily show video of the 84- perfect implementation of a simple device. very clever. Dick
