Abstract
Proportional reasoning is a key aspect of numeracy that is not always developed naturally by students. Understanding the types of proportional reasoning that students apply to different problem types is a useful first step to identifying ways to support teachers and students to develop proportional reasoning in the classroom. This paper describes the development of a diagnostic instrument that aims to identify situations in which students can apply proportional reasoning and the types of reasoning they use.
