Abstract
An important component of the algebra needed to do mathematics with a computer algebra
system (CAS) is symbol sense, analogous to ‘number sense’ in arithmetic with a four
function calculator. This paper presents an assessment of a component of symbol sense:
algebraic expectation. We describe the results of 169 Year 11 students including interesting
individual items and correlations with other measures. Initial analysis shows the test is
successful in monitoring both algebraic skills and students’ certainty in these skills, both
of which affect success with using CAS.
