Abstract
Proportional reasoning has been recognised as a crucial focus of mathematics
in the middle years and also as a frequent source of difficulty for
students (Lamon, 2007). Proportional reasoning concerns the equivalence
of pairs of quantities that are related multiplicatively; that is, equivalent
ratios including those expressed as fractions and percents. Students who
do not learn to reason proportionally are unequipped to learn mathematics
topics such as similarity, scaling, and trigonometry. Proportional reasoning
is also essential to understanding rates and hence many science concepts
such as speed, density and molarity.
