One of the most frequent comments from students
when going over errors made on mathematics tests and assignments
is, oh that was just a stupid mistake. We do not allow students to
classify mistakes in this manner. We insist that the mistake be
acknowledged as something important that must not be repeated. We
seek to classify this error in a manner that will facilitate its
correction. So instead of calling it a stupid mistake, we offer
more useful categories like multiplication fact error, long
division process error, slip in concentration, or lack of
automaticity. Then we establish a practice procedure to avoid more
instances of that particular error.
One of our means for building automaticity is a piece of software
we developed called Mathdrill (May, Rabinowitz, Hart, and Larson,
1995). This program was designed to drill students in algebraic
principles in order to help students respond accurately, quickly
and – ultimately – automatically. The program was based
on the resource literature reviewed and mentioned in other sections
of the book as well as on the memory findings summarized by
Salisbury (1990) that are
relevant to drill programs. These include using: small subsets of
items to teach new concepts in order to reduce interference;
spaced, rather than massed, practice to improve retention; and
occasional review or reinstatements of earlier learned material in
which the concepts are mixed to facilitate discrimination,
retention, and appropriate use.
During the two-year interval between 1995 and 1997, we conducted a
controlled experiment to test the effectiveness of Mathdrill in
skills development. The results supported our hypothesis. (May, Rabinowitz and Mantyka,
2002, pp. 27-33)
Many math educators are content with a minimum level of competency
in topic areas. Our experience has been that unless core algebraic
skills are over-learned to the point of automaticity, errors in
these skills occur in more complex problem-solving situations. Our
experience supports the Blanchard and Shula principle cited
earlier, "Practice does not make perfect. Perfect practice makes
perfect" (2001, p. 46) and we require all our students to engage in
perfect practice. If you want to teach or learn mathematics well,
you must be prepared to do the same.
