This study examined middle school prospective teachers’ interpretations of multiplicative situations–multiplication and division–when solving problems with fractions. Multiplication situations with fractions are at the heart of middle school mathematics, so learning and teaching this concept is crucial. To improve learning and teaching these concepts, there is a need to educate middle school prospective teachers and design education programs for middle school prospective teachers to support their reasoning. Through coursework which emphasizes the importance of fraction-as-number and various interpretation of multiplicative situations with fractions with various curriculum materials, prospective teachers would be more competent in operating with fractions. In this study, middle school prospective teachers’ solutions were examined through a perspective that connects multiplication and division into a coherent framework. The analytical framework of this study placed emphasis on multiplication, partitive division, and quotitive division situations. The data were collected from 13 middle school prospective teachers’ final exam problems completed as part of a content course at a large university in the Southeastern United States. Findings revealed that (a) prospective teachers used strategies involving multiplicative situations after completing a two-semester sequence of mathematics content courses on fraction tasks (b) this instructional approach supported the development of an understanding of multiplicative operations with fractions and understanding of the meaning of multiplication and division for middle school prospective teachers, and (c) when allowed to choose methods prospective teachers used the partitive division (PDS) more often than the quotitive division (QDS) and multiplication situation (MS) correctly and appropriately.

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...
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...
Middle school mathematics teachers’ perceptions of inclusion and their use of teaching strategies in basic arithmetical operations and problems Gülden, Berna; Akyüz, Didem; Department of Elementary Science and Mathematics Education (2019) The aim of this study is to examine the perceptions of middle school mathematics teachers about inclusion and their teaching strategies in basic arithmetical operations and problems. In addition, the other purpose is to investigate opinions of middle school mathematics teachers about touch point, concrete-representational-abstract (CRA) and virtual-representational-abstract (VRA) strategies. The study was carried out in the 2018-2019 academic year in a middle school in Küçükçekmece, Istanbul with six mathem...
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 ...
Pre-service middle school mathematics teachers’ proportional reasoning before and after a practice based instructional module / Pişkin Tunç, Mutlu; Çakıroğlu, Erdinç; Department of Elementary Education (2016) The purpose of this study was to investigate pre-service middle school mathematics teachers’ proportional reasoning before and after receiving a practice-based instructional module based on proportional reasoning. Data were collected from three pre-service teachers in the spring semester of 2012-2013. Pre-service teachers were junior students enrolled in elementary mathematics teaching program at a public university. A practice-based instructional module based on proportional reasoning was carried out durin...
