Dear Everyone,

Tomorrow we will finish up chapter 5 by doing a few examples of applying Newton's Laws. I included one of these examples in the on-line notes for Tuesday's class, and I just posted another. We'll do more than those two but I'll post the notes for the rest after class (I'm still working on a couple of things!).

Let me address the transmitter issue, and we've definitely had problems so far this semester with those. Tomorrow we'll go with 1 minute 45 seconds as the time in which you can enter responses (that worked well at the end of yesterday's class).

In addition I have gone back and re-graded everyone for the first five classes worth of responses from the transmitters. Remember the grading system was 4 points for a correct answer, 3 for an incorrect answer, and 0 if the system did not register a response for you. I have modified this to give you 3 points any time the system did not register a response (as long as the system registered at least one response for you on a given day, so I know for sure you were there). That's not perfect, but at least you're getting 3 points for those unregistered answers instead of 0.

I will keep grading this way until the system works reliably, which I optimistically hope will be tomorrow.

To anyone who missed a day's worth of responses because your transmitter needed new batteries, or something like that, I think I have given you all credit for being there but e-mail me back just to make sure, please.

cheers,

Andrew Duffy
