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…

Ortiz, Enrique – Issues in the Undergraduate Mathematics Preparation of School Teachers, 2020
This paper details an exploratory study of ten elementary preservice teachers (PSTs) involvement in the problem-solving process in a mathematics methods course. The dynamic, messy and nonlinear nature of this process was demonstrated by discussing PSTs' solution process of an open box construction problem. Effective approaches to solve this…

Walkington, Candace; Chelule, Geoffrey; Woods, Dawn; Nathan, Mitchell J. – Grantee Submission, 2018
Gestures have been shown to play a key role in mathematical reasoning and be an indicator that mathematical reasoning is "embodied" -- inexorably linked to action, perception, and the physical body. Theories of extended cognition accentuate looking beyond the body and mind of an individual, thus here we examine how gestural embodied…

Zeybek, Zulfiye – International Journal for Mathematics Teaching and Learning, 2016
This study aimed to document pre-service elementary teachers' (PSTs'), who are going to teach K-5, ability to construct as well as evaluate justifications varied in terms of levels of sophistication. Additionally, this study aimed to investigate how PSTs' knowledge of content in which they were being asked to prove influenced their ability to…

Murata, Aki; McGee, Anna; Madkins, Tia C.; Fabrega, Judith; Kim, Hee-Jeong; Gillingham, Denny; Shareff, Becca L. – AERA Online Paper Repository, 2016
This study investigated the learning process of preservice elementary teachers (PSTs) through lesson study in a mathematics teaching methods course. Lesson study meeting data of kindergarten PSTs were analyzed to examine the shifting focus on (1) student collaboration in classroom (vision), (2) teaching practices (making content accessible), and…
