Researchers suggest that students have preferences (visual and non-visual) when solving mathematics problems. Many times students have difficulties in solving problems because of one-sided thinking and weakly associating other representations. Reform efforts support connecting visual representations with nonvisual representations in order to develop deeper understanding. This study investigates how prospective teachers with different preferences for visual, non-visual, and harmonic thinking solve geometry problems with and without using DGS. The study aims to explore whether students‘ use of DGS when solving geometry problems is related to their preferences. Suwarsono‘s mathematical processing instrument (MPI) was administered to determine their preferences for visual and non-visual thinking. Based on MPI instrument‘s results and their performances of geometry problems solved with and without DGS, three students were selected to be interviewed. Multiple case studies were conducted to conduct a deeper analysis. The reason for selecting three students was to take at least one person from each group based on their thinking preferences so that different cases can be compared and contrasted. The results reveal that regardless of students‘ preferences preservice teachers preferred to use visual solutions when they are asked to use DGS. When their solutions of DGS and paper-and-pencil were compared, students‘ solutions with DGS demonstrated more conceptual understanding of the task than paper-and-pencil.

The role of dynamic geometry software on mathematical creativity of pre-service mathematics teachers in geometry tasks
Melek, Zülal; Çakıroğlu, Erdinç; Department of Mathematics Education (2021-7-14)
The purpose of the study was to investigate the role of the dynamic geometry software on mathematical creativity of pre-service mathematics teachers in geometry tasks. The sample of the present study was five pre-service mathematics teachers in a public university in Ankara. The sample of the study was selected by the convenience sampling method from the pre-service mathematics teachers who took Exploring Geometry with Dynamic Geometry Applications course. The pre service mathematics teachers asked to...
Investigating the use of technology on pre-service elementary mathematics teachers' plane geometry problem solving strategies
Koyuncu, İlhan; Akyüz, Didem; Çakıroğlu, Erdinç; Department of Elementary Science and Mathematics Education (2013)
The purpose of this study was to investigate plane geometry problem solving strategies of pre-service elementary mathematics teachers in technology and paper-and-pencil environments after receiving an instruction with GeoGebra. Qualitative research strategies were used to investigate teacher candidates‘ solution strategies. The data was collected and analyzed by means of a multiple case study design. The study was carried out with 7 pre-service elementary mathematics teachers. The main data sources were cla...
Investigating perceptions of preservice mathematics teachers on their technological pedagogical content knowledge (TPACK) regarding geometry
Bulut, Aykut; Işıksal Bostan, Mine; Department of Elementary Science and Mathematics Education (2012)
The aim of this study is to investigate perceptions of preservice mathematics teachers’ technological pedagogical content knowledge (TPACK) regarding geometry. In addition, the purpose is to examine the relationships among the components of TPACK. Moreover, possible gender and year of enrollment differences related to preservice mathematics teachers’ technological pedagogical content knowledge dimensions are examined. This research study has been conducted with 780 preservice mathematics teachers who are en...
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...
Developing the understanding of geometry through a computer-based learning environment
Üstün, Işıl; Ubuz, Behiye; Department of Secondary Science and Mathematics Education (2003)
The main purpose of the study was to investigate the effects of a dynamic instructional environment (based on use of Geometer's Sketchpad) on 7th grade students' understandings of lines, angles, and polygons and their retention. Besides that, the students' attitudes towards computer instruction and its relation with students' performance on geometry and retention were investigated. The study was carried out with 63 7th grade students from two classes taught by the same teacher in a state elementary school i...
