The purpose of the current study was to document preservice middle school mathematics teachers’ (PMSMT) classroom mathematical practices emerged through six-week instructional sequence about triangles. In this respect, the research question of “What are the classroom mathematical practices that are developed within design research environment using problem-based learning for teaching triangles to preservice middle school mathematics teachers?” guided the present study. In order to answer this research question and document the mathematical practices, a hypothetical learning trajectory and instructional sequence lasting six weeks related to triangles were formed. The hypothetical learning trajectory for the instructional sequence was performed for PMSMT to document their classroom mathematical practices about triangles. The classroom mathematical practices were analyzed benefiting from collective learning activity of whole class discussions including individual learning and social aspects of the environment by using emergent perspective. Focusing on taken-as-shared knowledge identified by Toulmin’s argumentation model, the classroom mathematical practices were extracted. The classroom mathematical practices encouraging PMSMT’s learning of triangles in the present study were: PMSMT’s reasoning on (a) the formation of a triangle, (b) the elements of triangles and their properties, and (c) congruence and similarity. Based on these mathematical practice, PMSMT improved their understanding of the concept triangles benefiting from other geometry concepts such as transformation geometry, geometric constructions and argumentations. In this respect, they examined the properties and elements of triangles and related properties by developing their conceptual understanding.

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...
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 ...
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...
Developing mathematical practices in a social context: a hypothetical learning trajectory to support preservice middle school mathematics teachers’ learning of triangles Uygun, Tuğba; Akyüz, Didem; Department of Elementary Education (2015) The purpose of the current study was to document preservice middle school mathematics teachers’ (PMSMT) classroom mathematical practices emerged through six-week instructional sequence about triangles. In this respect, the research question of “What are the classroom mathematical practices that are developed within design research environment using problem-based learning for teaching triangles to preservice middle school mathematics teachers?” guided the present study. In order to answer this research quest...
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...
