ab: This paper examines Year 7 students use and learning of ratio concepts
while engaged in the technology practice of designing, constructing and
evaluating simple machines, that used cogs and pulleys. It was found
that most students made considerable progress in accounting for ratio
concepts in their constructions and some constructed sophisticated
machines and provided explicit and quantitative descriptions involving
ratio reasoning. The findings have implications for the study of
mathematics in integrated and contextual settings.
