Schedule at a Glance (see archives for older entries)
Written assignments should follow the HW guidelines.


T 5/16/06

HW due: Work with your study buddy for at least 15 minutes outside of class. If you do not have a study buddy, come to Math Lab Monday afternoon to work with me. Keep a written time log.

The students who have already passed the Must-Pass Quiz (namely, Alex, Andrew B., Christian, Glenn, Henry, John, and Michael M.) did not get to that point by chance alone. I am fairly confident that I did not commit a Type I error!


W 5/17/06

First half: Mr. Joe Morris of the MITRE Corporation will speak on the history of computers. This is a fascinating talk, covering many of the technologies that we take for granted today.

Second half: The Must-Pass Quiz continues.


Th 5/18/06

HW due: Read Lessons from the Pentagon if you have not already done so. Then, as you did earlier in the week, work with a study buddy (either as a person seeking help, or as a person providing help) for at least 15 minutes outside of class, and keep a time log of your efforts. Students who still need help getting over the hurdle are Ben, Clay, Chris, Greg, Jeffrey, Kenny, Paul, and Will.

Note: Today’s class will be held from 9:45 to 10:25, after assembly.


F 5/19/06

Last day of class. I know many of you still have a cut remaining, but it would mean a lot to me if you would come to class today. I will waive the exam requirement if 100% of students pass the Must-Pass Quiz by the end of the day Monday, May 22. (That is an extension because of the late start we had to yesterday’s class.)

The period today is full length, because we had the Friday schedule yesterday.


M 5/22/06

. . . and there was much mirth and merriment throughout the Close. All 17 students have now passed the Must-Pass Quiz! Check out the tote board. This means, per our agreement, that the final exam requirement is waived for everyone.

Thanks, everyone, for a great, memorable year. See you on Prize Day!
