## A Computer for All Students--Revisited

An Article Review by Lari Garrison

Bert K. Waits and Franklin Demana are well-known
for their support of the use of graphing technology in the mathematics classroom.
In this article they are commenting on an article they wrote in 1992, in
which they were actually opposed to integrating computer algebra systems
into high school mathematics. With the development of new technology, such
as the TI-92, Demana and Waits feel that many of the barriers to successful
integration of CAS are gone. Reasons, such as cost, made using CAS impractical,
especially when graphing calculators were so cheap in comparison. As the
price of CAS goes down the likelihood that all students will have access
to it is increased, so their reservations are gone. They address some of
the potential problems that teachers will have to face as the use of CAS
becomes more prevalent. Teachers will have to decide how to convince the
public that students are actually learning better mathematics through the
use of CAS, and they must decide what in the curriculum should be "reemphasized."
They point out that another need is for textbooks and other materials which
are designed to take advantage of the technology. Certainly many exercises
in older, traditional textbooks will become trivial when CAS is used in
the classroom. When one thinks about the advantages and benefits of using
CAS in the classroom the hurdles teachers face seem insignificant. Students
will spend less time learning tedious mechanical algorithms, which CAS can
do for them, and more time learning richer higher-level mathematics.
