Abstract
The development of students' algebraic understanding is generally accepted to be one of the
major goals of K-12 mathematics teaching. In this paper I attempt to examine this
understanding by characterising a group of high school students' algebraic knowledge and
patterns of use of that knowledge during the solution of selected problems. Results show
that these students tended to show acceptable levels of proficiency with problems that
involve substitution of values for variables, and simplification of equations. However,
students experienced difficulties with the solution of equations and the interpretation of
variables both in symbolic and graphical modes. These results are interpreted as suggesting
that the participating students' understanding was buttressed mainly by schemas that were
dominated by procedural knowledge of algebra.
