title = "Opportunities for saming realizations in different tasks",

abstract = "The Realization Tree Assessment (RTA) tool offers a graphical presentation of the mathematical ideas students got exposed to and engaged with through a certain task. It depicts the mathematical object together with its different realizations, the extent to which opportunities for saming those different realizations were given to students during a lesson and the extent to which students had authority to produce narratives about the object. Five mathematics lessons which were based on a middle-school task dealing with linear functions were analysed using the RTA. The results were compared to RTAs of lessons based on a pattern generalization task. We discuss the similarities and differences between the RTAs in terms of opportunities for explorative participation as well as exhausting the potential of a task.",
