From additive to multiplicative thinking: The role of feedback from a computer app

Multiplicative thinking is an important aspect of mathematics education, such as with ratio and proportion. A particular computer App called Stick and Split (SaS) requires multiplicative thinking in tasks which require rods of a given length to be made by sticking together rods of equal length, and splitting rods into equal lengths.  This research is a preparatory study which aims to examine whether the design of the Stick and Split (SaS)  App can influence the nature of thinking which a young student might bring to the App’s tasks.
