PME-37-SO-1 is a very early report of a collaborative work with one of my Ph.D. students, Sepideh, on a design to cultivate learning of negative numbers in an algebraically useful way. The paper was accepted as Short Oral, not as Research Report since, at that time, we hadn’t got enough data to support our idea. It is here to show the origin of our extended experimental research done later on.
