Abstract
The research reported in this paper is part of a large studyl investigating the
cognitive and linguistic aspects of learning algebra in secondary school. Five of the
22 schools participating in the study tested the same cohort of students on two or
three occasions. Analysis of the data from these five schools has shown that
certain initial difficulties are easily corrected for the majority of students, whereas
others are more persistent. Most students by Years 9 and 10 had reached an
understanding of algebraic letters as unknown numbers, but their understanding of
equations was less secure. Major persistent difficulties were the significance of
brackets and the notation for products and powers. A small proportion of students
made very little or no progress.
