Prospective Mathematics Teachers' Use of the Angle Tool in GeoGebra in a Geometric Construction Task
Peer reviewed
Direct linkOkumus, Samet; Bozkurt, Gulay – International Journal for Technology in Mathematics Education, 2022
This case study investigates prospective middle school mathematics teachers' use of the Angle tool in GeoGebra, focusing on reflex angles in a geometric construction task. They constructed a parallelogram with individual heights for any two consecutive sides. We analyzed their screencasts to identify the ways in which they used reflex angles in…

We report the design of an analog technology, what we refer to as a SunRule, that uses sunlight to model multiplication. Physical models that explore multiplication are fixtures in elementary mathematics classrooms. Our interest in physical models of multiplication was driven by an overarching design problem: How could a physical tool realize a…
