My paper - Number Theorizing with Talented Youth - was accepted for publication in a special edition of the School Science and Mathematics Journal (USA) on gifted and talented mathematics and science students. The paper was published in the Volume 99, Number 6, October 1999, edition of School Science and Mathematics (pages 348-353).
    This paper is a much abbreviated version of a substantial document with the same title, which describes some of the work (the most important, I should add) that I did with a group of sixteen students in July 1993 in the Irish Centre  for Talented Youth at Dublin City University in its first year of operation.
    My entire emphasis was on trying to get students to think about serious mathematical questions. I believe I succeeded ... . See for yourself, and let me know what you think.

The entire test of the original 53-page document is now available here in pfd format (1048KB).

I greatly value Paul Halmos' opinion of the above document.

From Terence Tao's web site I have come to know of the John Hopkins University SET site.
