FEBRUARY SUGGESTIONS:
AMTE  the mailing list of the Association of Mathematics Teacher Educators, archived by the Math Forum at: http://forum.swarthmore.edu/epigone/amte/
 Substitution (29 Jan. 2000) http://forum.swarthmore.edu/epigone/amte/belgandjy/
"The common element I find in most if not all of the problems that students have that I find most baffling is some kind of substitution... It seems like if I could understand this one problem that it might shed light on a lot of other things. Can anyone help?"  Shelley Walsh
The thread references an essay by Ralph Raimi, "On Solving Equations, Negative Numbers, and Other Absurdities," at http://www.math.rochester.edu:8080/u/rarm/equation.html.

APCALC  the Advanced Placement Calculus mailing list, hosted by the Educational Testing Service (ETS) and archived at: http://forum.swarthmore.edu/epigone/apcalc/  DE MOIVRE'S THEOREM (2 Feb. 2000) http://forum.swarthmore.edu/epigone/apcalc/clehleeblex/ "Can someone provide a motivator for studying de Moivre's theorem either (1) because the student will need it in a future math course he/she is likely to take, or (2) because of its application to real world problems?"  Norman Mikalac
______________________________ + ______________________________
MATHEDU, a mailing list set up to discuss issues in Mathematics/ Education at the postcalculus level, and archived at http://forum.swarthmore.edu/epigone/mathedu/  The Real Numbers (17 Feb. 2000) http://forum.swarthmore.edu/epigone/mathedu/keetwerdthang/ "I have used this construction of the reals in my Real Analysis course for half a dozen years now, and it has tremendous pedagogical benefits...."  Mark Bridger

 Indian astronomy and mathematics (14 Jan. 2000) http://forum.swarthmore.edu/epigone/historia_matematica/pawesming/
"Indian 'tables' of planetary parameters are lists first appearing in treatises of the middle of the first millennium CE. The suggested redatings of the Vedic texts to the fourth millennium BCE or earlier, which have been proposed in various forms over the past couple of centuries, are based on attributing a very high degree of precision to some statements in them about the relation of star positions to direction and seasons...."  Kim Plofker
Astronomical eventdating of the Vedic texts, Indian mathematicians after 1000 A.D., the heliocentric model of Aryabhata, Ptolemy and Copernicus, and more.
