Subject: good uses of calculators
Dear colleagues,

We (Al Cuoco, Paul Goldenberg, and June Mark) edit the ``Technology

Tips'' column for the NCTM journal ``Mathematics Teacher.'' You may have

noticed it in recent issues. We try to highlight good uses of technology, ways

to integrate technology with your curriculum, and pointers to technological

resources of use to high school mathematics teachers. Recently, we've had

articles on the use of dynamic geometry software, spreadsheets, the Internet,

and function machines.

We'd like to devote a column or two to calculators, giving short examples of

calculator uses that people have found effective either for learning or

applying mathematics. We also want to give a few examples of situations where

calculators don't help or even get in the way of understanding. By

``calculator'' we mean all varieties, including graphing calculators.

Although it is read by a much wider audience, the ``Mathematics

Teacher'' is aimed at the 9-12 curriculum, and we'd like submissions

that relate to that level mathematics. Submissions should be at most

two paragraphs. We can't guarantee inclusion, and we may have to

combine and edit, but we'll credit the people whose ideas we pubish.

So, what's your favorite activity with a calculator? When is it best to

turn them off? More important than the description of the activity is

the description of the calculator use that you applaud or boo. And, in addition

to how the calculator is used, we'd like to know about the underlying

rationale (for example what's the mathematical thinking that it encourages?).

Send submissions by June 9 to techtips@edc.org and cc one of us (alcuoco,

paulg, or junem, all @edc.org).

Thanks.
