The present study, as a small part of a larger project, is an attempt to examine prospective middle school mathematics teachers' personal and instructional definitions of quadrilaterals with mathematical and didactical considerations. Data were obtained from eight prospective teachers via individualized open-ended prompting clinical interviews. Data analyses were executed using thematic coding by synthesizing past and current theories about learning and teaching of geometry. Results indicated that prospective teachers generally had difficulties when defining the concepts by establishing necessary and sufficient conditions although they could provide inclusivity in their definitions. Furthermore, they tended to use their personal definitions of quadrilaterals as instructional definitions. However, they provided limited didactical considerations for their instructional definitions without a complete awareness about possible effects of their definitional preferences on the students' learning of quadrilaterals.

PROSPECTIVE MATHEMATICS TEACHERS' MATHEMATICAL KNOWLEDGE FOR TEACHING Işıksal Bostan, Mine (2011-07-06) In this study we aimed to examine prospective elementary mathematics teachers' mathematical knowledge for teaching. More specifically, our aim was to understand whether the Teaching Method Course had an effect on prospective mathematics teachers' mathematical knowledge. The study was conducted with 31 prospective elementary mathematics teachers in a large public university in Ankara, Turkey in 2010-2011 fall semester. To collect data, a survey instrument including 5 open-ended questions was developed by the...
Prospective Teachers' Noticing with respect to the Student Roles underlined in the Elementary Mathematics Program: Use of VideoCases Osmanoğlu, Aslıhan; Işıksal Bostan, Mine; Koç, Yusuf (2012-07-01) The purpose of this qualitative case study was to examine what prospective mathematics teachers noticed with respect to the student roles underlined in the elementary mathematics program when video-case based pedagogy was employed in teacher education. The theoretical framework employed in this study was Learning to Notice framework developed by van Es and Sherin (2002). The data was collected through reflection papers and interviews from 15 senior prospective teachers enrolled at a large state university. ...
Prospective Middle School Mathematics Teachers' Covariational Reasoning for Interpreting Dynamic Events During Peer Interactions Yemen-Karpuzcu, Secil; Ulusoy, Fadime; Işıksal Bostan, Mine (2017-01-01) This study investigated the covariational reasoning abilities of prospective middle school mathematics teachers in a task about dynamic functional events involving two simultaneously changing quantities in an individual process and also in a peer interaction process. The focus was the ways in which prospective teachers' covariational reasoning abilities re-emerge in the peer interaction process in excess of their covariational reasoning. The data sources were taken from the individual written responses of p...
Prospective Mathematics Teachers' Views on the FATIH Project: The Big Educational Technology Movement in Turkey Cevikbas, Mustafa; Cevikbas, Seher (2015-01-01) The purpose of the present study was to evaluate the FATIH Project from the perspective of future mathematics teachers. Contributions to the education system derived from the project, and related problems that emerged from the implementation process, were investigated based on the prospective teachers' observations. Qualitative research methods were used in the study, and the participants were 50 prospective mathematics teachers, who were senior students from a state university in Turkey. They were selected...
Prospective Teachers' Knowledge on Middle School Students' Possible Descriptions of Integers Kubar, Aysenur; Çakıroğlu, Erdinç (2017-01-01) This study aims to reveal prospective middle school mathematics teachers' knowledge regarding the possible misconceptions and/or errors of middle school students in describing integers. In addition to this, it aims to reveal the possible reasons underlying these from the perspective of prospective teachers. Data was qualitatively collected from 38 Turkish prospective teachers by an open-ended questionnaire. The results show that although prospective teachers are familiar with possible misconceptions and/or ...
