Middle and high school mathematics teachers' perspectives on the use of 3d diagrams in teaching geometry

Yıldızel Saygılı, İlkay
This study investigates the perspectives of middle and high school mathematics teachers on the application of three-dimensional diagrams in geometry teaching. A supporting aim was also to obtain their suggestions on supporting students’ diagrammatic reasoning and addressing misconceptions and difficulties that may arise. The study's participants are 12 math teachers working in Turkey on face-to- face and online platforms. Data were collected through semi-structured, open-ended, and task-based interviews with every participant and examined using content analysis. Math teachers’ perspectives on using 3D diagrams were categorized in terms of the role they assign to them in teaching geometry, their value as teaching resources, and their awareness of students’ misconceptions and difficulties. While thought necessary to understand geometry, this study found that teachers prefer to use 2D and 3D diagrams in a two-dimensional way rather than digital ones when teaching. They also feel their students would benefit from materials integrating each question with a QR code so that questions can be better understood through multiple images, along with suggestions for digital courses for pre-service teachers and digital workshops for teachers.

Pre-service middle school mathematics teachers’ understanding of quadrilaterals through the definitions and their relationships
Öztoprakçı, Seçil; Çakıroğlu, Erdinç; Department of Elementary Education (2014)
The purpose of this study was to examine pre-service mathematics teachers’ cognitive progress in constructing and evaluating quadrilateral definitions and the corresponding quadrilateral hierarchies under the support of the Geometer’s Sketchpad learning activities. The study employed qualitative case study design of which data was collected from 5 pre-service middle school mathematics teachers during the spring semester of 2010-2011. The main data came from one-to-one clinical interview sessions assisted wi...
Middle school mathematics teachers' problems in teaching transformational geometry and their suggestions for the solution of these problems
İlaslan, Serap; Çakıroğlu, Erdinç; Bulut, Safure; Department of Elementary Science and Mathematics Education (2013)
The purpose of this study was to reveal and define the problems middle school mathematics teachers experienced in applying transformational geometry and the solutions they proposed to overcome these problems. A total of six elementary mathematics teachers (grades 5-8) in Ankara participated in the study. The data were collected by means of one-to-one interviews with the participants. The findings indicated that the participants’ problems divided into three parts. These problems were problems arising from te...
Pre-service middle school mathematics teachers’ pedagogical content knowledge regarding the area of triangles
Bilik, Aslı; Işıksal Bostan, Mine; Department of Elementary Science and Mathematics Education (2016)
The purpose of this study was to investigate pre-service middle school mathematics teachers’ pedagogical content knowledge on the concept of the area of triangles. In this respect, pre-service teachers' pedagogical content knowledge with respect to students' possible misconceptions/ difficulties regarding the area of triangles and the strategies that pre-service teachers employed to overcome these misconceptions/difficulties were examined. To conduct an in-depth investigation regarding the purpose of the st...
An Analysis of prospective middle school mathematics teachers‘ argumentation structures in technology and paper-pencil environments
Erkek, Özlem; Işıksal Bostan, Mine; Department of Elementary Education (2017)
The purpose of the current study was to investigate the nature of argumentation structures of prospective middle school mathematics teachers while solving geometry tasks within the GeoGebra and Paper-Pencil groups. The study employed qualitative case study design and the data of which were collected from 16 prospective middle school mathematics teachers during the fall semester of the 2013-2014 academic year. Data were based on the video recordings of the implementations, the focus group interviews and docu...
Middle school mathematics teachers’ mathematical practices in teaching slope, linear equations, and graphs in technology enhanced classroom environment
Yemen Karpuzcu, Seçil; Işıksal Bostan, Mine; Department of Elementary Education (2017)
The aim of this study was to examine an in-service middle school mathematics teacher’s mathematical practices in teaching slope, linear equations and graphs in a technology enhanced classroom environment while enacting an instructional sequence that was designed based on the national curriculum. The technology utilized in the study was GeoGebra materials within computers that were developed by the teacher and the researcher to be used for the instructional sequence. The data was collected during the spring ...
