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 documents. The findings revealed five types of global argumentation structures, two of which emerged from the present study: Line-structure and Independent-Arguments structure. In addition, the participants employed 9 types of local arguments while three of them were most frequently preferred. Finally, the local argumentations were examined by focusing on the justifications of the participants. This analysis revealed the characteristics of the local argumentations that prospective middle school mathematics teachers use while solving geometry tasks in GeoGebra and Paper-Pencil groups.

Exploring secondary mathematics teachers’ conceptions of mathematical literacy
Genç, Murat; Erbaş, Ayhan Kürşat; Department of Secondary Science and Mathematics Education (2017)
The purpose of this research study was to investigate secondary mathematics teachers’ conceptions of mathematical literacy. In doing so, the following three crucial interrelated issues were addressed: (i) teachers’ conceptions of what the notion of mathematical literacy means, (ii) teachers’ conceptions of how the development of mathematical literacy could be facilitated, and (iii) teachers’ conceptions of what a mathematics curriculum emphasizing mathematical literacy should look like. The data gathered fo...
Prospective middle school mathematics teachers’ developing understanding of geometric transformations
Avcu, Seher; Çetinkaya, Bülent; Department of Sociology (2017)
The purpose of this study was to explore prospective middle school mathematics teachers’ developing understanding of geometric transformations during the implementation of a seven-week instructional sequence designed to have them gain a mapping understanding of geometric transformations. This instructional sequence involved exploring geometric transformations in both static and dynamic geometry environments. Participants of the study were sixteen prospective middle school mathematics teachers. Design-based ...
A Case study on middle grade mathematics teachers’ use of questioning in teaching lines and angles
Yılmaz, Ayşenur; Çakıroğlu, Erdinç; Department of Elementary Education (2018)
The purpose of the study was to identify tools that help teachers to use in teacher questioning in middle-grade mathematics classrooms. In addition to this, the study aimed to examine teachers’ questioning behaviors concerning teachers' question types and the interaction among the tools for questioning and question types. This study was applied a multiple case with two middle grade mathematics teachers. The participant teachers were video recorded for the lines and angles topic. In one of the classroom, tec...
Investigating preservice middle school mathematics teachers’ noticing of students’ mathematical thinking in the context of lesson study /
Güner, Pınar; Akyüz, Didem; Department of Elementary Education (2017)
The purpose of the current study was to examine preservice middle school mathematics teachers’ noticing of students’ mathematical thinking in the context of lesson study professional development model and determine whether any changes took place in their noticing skills. Qualitative research methodology, in particular, case study was used in order to elaborate what and how preservice teachers notice during lesson study phases which are planning, teaching, reflecting, re teaching and re-reflecting. With this...
