The aim of this study was to investigate the Technological Pedagogical Content Kowledge (TPACK) Development of the in-service mathematics teachers in the field of geometry through participating in mathematics coaching. In order to achieve the purpose of the study, two elementary mathematics teachers working in public schools in Black Sea Region participated in the study. The method of qualitative research was used to get deep and rich information about the development of elementary mathematics teachers’ TPACK in the field of geometry. Data was collected from 1) pre-interview, 2) observation of teacher before mathematics coaching, 3) pre-conferences, 4) observation of the teachers during mathematics coaching, 5) post-conference, 6) observation of teacher before mathematics coaching, 7) post-interview, 8) mathematics coaching interview. The progress of teachers’ TPACK was analyzed by considering the TPACK Development Model using deductive analysis. The findings revealed that in-service teachers moved from PCK to TPACK by participating in mathematics coaching. At the beginning of the study, in-service teachers exemplified primarily lower levels of TPACK development. Through the mathematics coaching, they progressed from lowest levels to highest levels in all the themes and their related descriptors: the curriculum and assessment theme, the learning theme, the teaching theme, and the access theme. Besides, the slowest progress was observed in the assessment descriptor among all the descriptors in which progress was made during mathematics coaching. The findings also demonstrated that the more-experienced teacher’s progression in the TPACK Development Model was faster than that of the less-experienced teacher during mathematics coaching.

Technological pedagogical content knowledge (tpack) development of preservice middle school mathematics teachers in statistics teaching: a microteaching lesson study
Kurt, Gamze; Çakıroğlu, Erdinç; Department of Elementary Education (2016)
The current study examined the development of technological pedagogical content knowledge (TPACK) of preservice mathematics teachers in statistics teaching with virtual manipulatives in the context of a microteaching lesson study (MLS). Since “technology integration is described by how and why it is used rather its amount or type”, integrating technology into education necessitates investigation of instructional uses of digital tools and resources (Earle, 2002, p. 8). TPACK framework suggested by Koehler an...
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...
A Pre-service mathematics teacher’s technological pedagogical content knowledge regarding different views of 3-d figures in geometry
Saralar, İpek; Işıksal Bostan, Mine; Akyüz, Didem; Department of Elementary Science and Mathematics Education (2016)
This study attempted to investigate a pre-service mathematics teacher’s Technological Pedagogical Content Knowledge regarding different views of 3-D figures in geometry. Data were collected from a pre-service teacher, enrolled in one of the large public universities in Ankara while she was teaching different views of 3-D figures in seventh-grade level in one of the private schools. Interviews, observations, field notes, GeoGebra files, and lesson plans were the data collection tools used in the study. Data ...
Promoting and investigating pre-service middle school mathematics teachers' TPACK-practical development in the context of an undergraduate course
Koştur, Merve; Haser, Çiğdem; Department of Elementary Education (2018)
The purpose of the study was to enhance and investigate the technological pedagogical content knowledge-practical (TPACK-P) development of pre-service middle school mathematics teachers (PMTs) through the Technology Use in Mathematics Education (TUME) course aiming TPACK-P development in three pedagogical domains: Assessment, Planning and Design, and Enactment. TUME course was designed and implemented based on four principles driven from the TPACK and TPACK-P frameworks which were transformative approach, c...
Use of learning trajectories based instruction to restructure pre-service elementary teachers’ mathematical content and student knowledge
Yılmaz, Zuhal; Haser, Çiğdem; Department of Elementary Education (2015)
The purpose of this study was to explore elementary pre-service teachers’ (PTs) mathematical content knowledge (MCK) and student knowledge (SK) restructuring practices for equipartitioning related mathematical ideas. Nine senior PTs from a private university located southeastern part of the Turkey were voluntarily participated to Learning Trajectories Based Instruction (LTBI) teaching experiment. Classroom video data, written works of PTs, pre-post tests and field notes were the main sources of the data col...
