"Mathematical knowledge for teaching" is a concept indicating the requirement for a specific kind of knowledge required to teach mathematics. Mathematical knowledge for teaching necessitates a more complex structure than what is required to carry out mathematical tasks and the knowledge to do that. The purpose of this study is to realize…

This qualitative research presents how a mathematics teacher educator's feedbacks to two lower secondary school mathematics teachers affects their design of hypothetical learning trajectories regarding teaching patterns and their teaching practice. The data comes from a web portal, which was designed as a professional development tool for…

This study focuses on the relationship among Content Knowledge (CK), Pedagogic Knowledge (PK), and Technological Knowledge (TK) using Technological Pedagogical Content Knowledge (TPACK). The aim of the study is to use the determined relationship to provide mathematical clarity using the Rough Set Theory, which is commonly used in areas such as…

Our study aimed to examine the transformation of pre-service mathematics teachers' theoretical knowledge into in-service mathematics teachers' instructional practice. We carried out seven focus group interviews, three individual phone call interviews, and classroom observations in four semesters with three Turkish pre-service mathematics teachers.…

This article examines the shared experiences and understandings teachers draw on to teach children with an awareness of linguistic diversity. To do so, we analyzed interviews from Turkey and the United States and drew on philosophical hermeneutics as a way to develop a disruptive understanding of teachers' views regarding the role of languages in…

This study investigated the relationship between prospective secondary mathematics teachers' perspectives and their mathematical knowledge for teaching in action. Data from two prospective teachers' practice-teachings, one in geometry and one in algebra, their lesson plans and self-reflections were analyzed with Teacher Perspectives and Knowledge…

The purpose of this study was to examine pre-service teachers' teaching practice in terms of providing suitable conditions for developing students' mathematical thinking in the frame of the Advancing Children's Thinking framework. In the study, Advancing Children's Thinking framework developed by Fraivillig et al. was adopted as theoretical…

The purpose of this study was to investigate the development of pre-service physics teachers' pedagogical content knowledge (PCK) on the subject of electricity and magnetism after their completion of physics and mathematics courses. A descriptive longitudinal development research was carried out with 13 pre-service teachers (PTs) who completed…

This study investigates the problems posed by Turkish pre-service primary teachers and explores the issues they encountered while posing problems related to fractions. A free problem-posing task was administered to 98 pre-service primary teachers who are in sixth academic term, and task-based interviews were conducted with eight volunteered…

The present study examined the structure of elementary pre-service teachers' mathematics anxiety and mathematics teaching anxiety by asking whether the two systems of anxiety are related. The Turkish Mathematics Anxiety Rating Scale Short Version and the Mathematics Teaching Anxiety Scale were administered to 260 elementary pre-service teachers.…

The purpose of this study was to investigate prospective mathematics teachers' knowledge of common conceptions and misconceptions that sixth and seventh grade students had about multiplication of fractions. In addition, prospective teachers' knowledge of the sources of these misconceptions and strategies they knew to overcome these misconceptions…

This study investigates the correlation between the mathematical beliefs and mathematics teaching anxieties of prospective primary education mathematics teachers. The investigation, which could be classified as a correlation study, has been conducted on 299 prospective teachers studying at the 1st, 2nd, 3rd and 4th grades of one of the state…

The aim of this study is to determine the primary school teachers' views related to the new Turkish primary school mathematics curriculum which was put into practice in the 2005-2006 academic years. A questionnaire developed by the researchers, consists of open ended and closed items, was applied to 60 primary school teachers selected randomly…
