Any suggestions would be greatly appreciated. - Janet Johnson - new teacher (19 July 2000) http://mathforum.org/epigone/k12.ed.math/fulnolprer/ "I was just wondering if any of you felt scared when you first started teaching. I don't think that I will have a big problem with it, but I feel that I won't be able to teach all of my future students everything that they need to know..." - Robin ______________________________ + ______________________________ NUMERACY, for those interested in the discussion of educational issues around adult mathematical literacy, archived at: http://mathforum.org/epigone/numeracy/ - Monty Hall (31 July 2000) http://mathforum.org/epigone/numeracy/jandgrendste/ "You are a contestant.

Break out the Klein bottles and Platonic solids!" - John Baez - Mental Limit? (17 Aug 2000) http://mathforum.org/epigone/sci.math/vanbinshou/ "I'm in need of some mathematical people to enlighten me with their point-of-view... Is there a mental limit of how far people can go in mathematics?" - Orion _________________________ + ______________________________ HISTORIA-MATEMATICA - a virtual forum for scholarly discussion of the history of mathematics in a broad sense, among professionals and non-professionals with a serious interest in the field, archived at http://mathforum.org/epigone/historia_matematica/ - Mayan numeration (2 Aug 2000) http://mathforum.org/epigone/historia_matematica/germzelkal/ "What reference(s) on Mayan mathematics are currently considered to be the most authoritative? In particular, is there a current resource which is both accurate and accessible to a non-specialist?" - Steven Johnson ______________________________ + ______________________________ We hope you will find these selections useful, and that you will browse and participate in the discussion group(s) of your choice.
