Abstract
In this study, we investigated students’ thinking about the use of letters in algebra.
Responses from over 1,400 Australian secondary school students to a set of three algebra
items were analysed to determine the prevalence of the “letter as object†misconception.
We estimate that 50% to 80% of Year 7 students bring this misconception to their initial
learning of algebra. Over 50% of Year 8 students and over 40% of Year 9 students in the
sample also selected responses consistent with this misconception.
