The research reported here is part of an ongoing study3 in which prospective middle school mathematics teachers’ conceptions of definition are investigated through their responses to semistructured interview questions about defining quadrilaterals. Here we present findings from their responses to a subset of the interview questions, with the purpose of understanding what they mean by the expression “definitions can be proved”- an expression commonly referenced, and considered as erroneous in the research literature. Analysis of the responses, through using thematic coding and Toulmin’s (1958) scheme, revealed that participants attributed two different meanings to the phrase: (1) proving the claim that a written definition accurately designates an intended concept and (2) proving the concept being defined (erroneous). Based on our findings, we point to a reconsideration of the phenomenon by the research community.

The role of definitions on classification of solids including (non)prototype examples: The case of cylinder and prism Işıksal Bostan, Mine (2017-01-01) The purpose of this study is to investigate prospective middle school mathematics teachers' (PMTs) formal definitions regarding cylinder and prism and the role of these definitions on their classifications of solids involving (non) prototype examples. Data were collected through questionnaire and interview protocol from three PMTs who were 3rd year students in one of the teacher education programs in Turkey. Data analysis revealed that PMTs mostly used inappropriate terminology in defining cylinder and pris...
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 ...
Why do prospective teachers have difficulties in mathematical modelling? Insights from their perspectives Sen Zeytun, Aysel; Çetinkaya, Bülent; Erbaş, Ayhan Kürşat (2023-01-01) This study investigated the sources of difficulties experienced by prospective teachers in mathematical modelling in the context of a semester-long course on mathematical modelling for teachers. The data reported in this study were collected from six prospective teachers through in-depth semi-structured interviews supported by audio and videotaped classroom observations and prospective teachers’ written solutions for the modelling tasks. The results showed that the sources of difficulties experienced by pro...
Investigation into prospective middle school mathematics teachers' noticing of students' algebraic thinking within the context of pattern generalization Özel, Zeynep.; Işıksal Bostan, Mine; Department of Secondary Science and Mathematics Education (2019) The purpose of this study was to investigate prospective middle school mathematics teachers’ noticing skills of students’ algebraic thinking within the context of pattern generalization. In order to obtain in- depth exploration and understanding of issue, the qualitative research method, in particular, the case study design was used. Thirty-two prospective teachers who were studying at one of the public universities located in Ankara were selected via purposive sampling as participants. Data was collected i...
An Investigation of prospective elementary mathematics teachers' probabilistic misconceptions and reasons underlying these misconceptions İlgün, Münevver; Işıksal Bostan, Mine; Department of Elementary Science and Mathematics Education (2013) The purpose of this study was to determine performance of prospective elementary mathematics teachers on answering the items handling the probabilistic misconceptions. The other aim was to investigate the underlying reasons behind these misconceptions of prospective elementary mathematics teachers. To address these aims, qualitative approach was performed. The sample of this study was obtained through convenience sampling. Data were gathered during 2011-2012 spring semester by administering Probability Misc...
