The purpose of this study was to obtain classroom mathematical practices of eighth graders’ during the concept of solids and to test the effectiveness of this content in an eighth-grade mathematics classroom. In this respect, an instructional sequence was used with guidance of a hypothetical learning trajectory. The context was basic elements of prisms, their surface area, basic elements of cylinder, its surface area and its volume. The process continued through four and half weeks. Argumentations, dynamic geometry software and daily life examples supported the classroom activities. Pretest and posttest were applied to the students to obtain the development of students’ understanding in related context. The classroom mathematical practices were obtained and analyzed by using emergent perspective as a theoretical framework. This view asserts learning occurs with combination of individual working and social aspects of environment. Using Krummheuer’s argumentation model which focus on taken-as-shared ideas, the mathematical practices were interpreted. Four mathematical practices were obtained as: (a) finding definition and properties of prisms, (b) finding surface area of prisms, (c) finding surface area of cylinder and (d) finding volume of cylinder. The results indicated that students’ understanding of three-dimensional solids improved with support of argumentations and dynamic geometry software.

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...
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...
An Investigation into middle school mathematics teachers‟ subject matter knowledge and pedagogical content knowledge regarding the volume of 3D solids
Tekin Sitrava, Reyhan; Işıksal Bostan, Mine; Department of Elementary Education (2014)
The purpose of this study was to examine middle school mathematics teachers' subject matter knowledge and pedagogical content knowledge of the volume of 3D solids. In order to achieve the purpose of the study, four middle school teachers working in public schools in Ankara participated in the study. To get deep and rich answers to research questions asked, qualitative methodology was used.Participants were selected through purposeful sampling. Data was gathered via questionnaire, semi-structured interviews,...
A case study of elementary mathematics teachers' views of their and students' textbook usage and of mathematics textbooks' characteristics
Başer, Nadiye; Haser, Çiğdem; Department of Elementary Science and Mathematics Education (2012)
The purpose of this study was to investigate teachers’ ways of using mathematics textbooks while planning the lesson and during the lesson, to document teachers’ views about elementary students’ usage of mathematics textbook during the classroom time and for their homework and teachers’ views about mathematics textbooks’ characteristics. A case study was conducted in a private elementary school with more class hours for mathematics and six mathematics teachers teaching 4th, 5th, 6th, and 7th grade mathemati...
