Abstract
Learning algebra is very difficult for many students, and one of the major
obstacles identified in the research literature is a 'cognitive gap' presented by
equations of the form ax+b=cx+d, which require operation on the variable for
solution. In this small-scale, preliminary study we assessed the value of a
computer environment which enables students gradually to investigate
algebraic expressions and equations. The initial results are very encouraging
and suggest that this may be a way to assist students to learn algebra in a
versatile way.
