Fall 2000, Spring 2001, and Fall 2001, I coordinated Math 135 , the first semester calculus course for students interested in majoring in subjects related to business, biology, and the social sciences. This course enrolled over 1700 students in fall 2000 and about 1000 in spring 2001. A major innovation in this course was the introduction of WeBWork, a program for web-based homework developed at the University of Rochester.

I have several times recently taught a graduate course on Mathematics and Materials Science and four happily-employed students have received Ph.D.s under my supervision.

The undergraduate courses I have taught most often are each of the three semesters of calculus for math and physical science majors, and linear algebra. I try to teach the smaller classes in a "reform" style, at least to the extent of having the students work moderately difficult problems in small groups for 15-20 minutes at the end of each class. I was pleased to see that a large proportion of the students who used to get grades of B+, B, and C+ can now earn A's. Sometimes students still fail in the same proportion as earlier. But here is an interesting statistic: in my most recent multivariable calculus class, 18 of the 66 who took the second midterm exam had not been attending class; of those 18, 10 got F's, 4 got D's, and 4 got C's. Of the 48 who did attend, only 2 failed. Still, 2 is 2 too many, and more students should be encouraged to stick with the course and attend class regularly.

Several times (most recently, fall 1996) I have taught a Freshman Seminar in the Douglass Scholars program, usually entitled Some New Mathematics. A highlight of that course has been the outside lecturers I have been able to bring in.

I have organized a number of activities at DIMACS programs for high school students for the past several years; these activities have centered around soap bubbles and crystals. I also occasionally visit local schools and talk to school teachers about mathematics activities both locally and at workshops. I did hands-on science activities at the NGO Forum associated to the UN Conference on Women in Beijing (under the auspicies of AAAS); I plan to write up my soap bubble-based activities for one of their projects.
