Presentation at PME48 – Mapping Objectification in Algebraic Discourse
At PME48 in Chile, Prof. Einat Heyd-Metzuyanim presented a Research Report led by Avital Elbaum-Cohen and co-authored with Prof. Michal Tabach, titled “Mapping Objectification in Early Algebraic Discourse.”
The study introduces a new tool for analyzing the development of algebraic discourse in middle school students, using the commognitive framework. By examining how students transition from arithmetic to algebraic discourse, we trace signs of objectification—the emergence of generalized numbers as objects.
