  This special issue of the Math Forum's weekly newsletter
  highlights recent interesting conversations on Internet 
  math discussion groups.

  For a full list of these groups with links to topics covered
  and information on how to subscribe, see:


  Replies to individual discussions should be addressed to
  the appropriate group rather than to the newsletter editor.

CALC-REFORM - a mailing list hosted by e-MATH of the 
American Mathematical Society (AMS) and archived at

Continued reactions to the Open Letter To Richard Riley -
see our November discussions newsletter, archived at:

- Math "Correct" ad in Washington Post and response (30 Nov. 1999)

- Maybe this checkbook thing is relevant after all (11 Dec. 1999)

This calc-reform conversation includes a letter from Hyman Bass 
to the Mathematical Sciences Education Board of the National 
Research Council, posted with his permission, followed by 
discussions about balancing a checkbook by hand.

FATHOM - a list to foster communication within the Fathom user 
community (Fathom is dynamic statistics software from Key 
Curriculum Press,, archived by 
the Math Forum at:

- Fathom User FAQ (10 Dec. 1999)

  "I've just put the beginnings of a FAQ of 'How do I ... in 
   Fathom?' questions onto the web..." - Jill Binker

GEOMETRY-SOFTWARE-DYNAMIC - a list for the discussion of such
geometry software programs as the Geometer's Sketchpad and
Cabri Geometry II, hosted and archived by the Math Forum at:

- Request for info. on History of Sketchpad, Cabri, Cinderella 
  (6 Dec. 1999)

 "I've been asked to write a review of the dynamic geometry 
  software package Cinderella, and am planning to compare it 
  to The Geometer's Sketchpad and Cabri Geometry..." - Heidi Burgiel  

  Followup at:
- My review of Cinderella -- thanks for all the help!

K12.ED.MATH - a moderated list on general math teaching 
questions, archived by the Math Forum at

- memorizing in math class (1 Dec. 1999)

 "Should we require students to memorize numerous theorems and 
  formulas for math quizzes and tests (i.e. Trig. identities or 
  all the formulas for area and volume)?" - Matt Kellogg

  Compare and contrast this discussion with those on the same
  question on the math-teach and math.teaching.styles lists:

SCI.MATH, a discussion group focused on general and advanced 
mathematics that can be read as a Usenet newsgroup or on the Web:

- countability and computability (22 Dec. 1999)

 "The set of all numbers that can be described by humans is the 
  set of all numbers that can be described using language (say), 
  and is therefore countable, as each can be represented by a 
  finite length string. From the uncountability of the reals, 
  this means there exist numbers that cannot be described by 
  humans (or computers). Is this equivalent to an uncomputable
  number?" - Dan Goodman

SCI.MATH.RESEARCH, a discussion group focused on research-level 
mathematics that can be read as a Usenet newsgroup or on the Web:
