An Investigation of pre-service elementary mathematics teachers’ techno-pedagogical content knowledge within the context of their teaching practices

Balgalmış, Esra
The goal of the case study was to investigate the contribution of field experience and the reflection-on-practice process on Turkish Pre-service Teachers’ TPACK. In 2011-2012 fall semester, the research was conducted with the participation of three PSTs. PSTs designed and implemented three technology-based lessons, primarily with GeoGebra. They were observed during the lesson and interviewed before and after each lesson implementation to reflect on their teaching. The data collection methods were reflective interviews, observations, videotaped lessons and documentation. The data were analyzed through qualitative data analysis methods. A five level TPACK rubric (recognizing, accepting, adapting, exploring and advancing) was used. The qualitative analysis of the data revealed that PSTs TPACK levels changed progressively throughout the study. Three components; the aim of the lesson, the questions used, and the role of the teacher provided important insights to determine the change in the TPACK level. PSTs’ interpretations of implementing technology-based mathematics lessons were examined. The thirteen themes emerged in the interviews were classified into three categories. The categories and their themes were the lesson preparation (students’ pre-knowledge, lesson objective, location, necessity of the technology, motivation), process of implementation (tool, teacher role, activity sheet, classroom management, time management, implementation), and mentorship (having a facilitator, and recommendation). In general PSTs defined educational technology as a tool that assisted them to promote students’ learning and increase students’ motivation. Findings support the need for teaching experience and reflection-on-action, to promote PSTs’ TPACK. These were the important components, which affected the overall success of their lesson implementation.


Investigating pre-service science teachers’ understandings and use of models
Yenilmez Türkoğlu, Ayşe; Öztekin, Ceren; Department of Elementary Education (2013)
To gain a better understanding of pre-service science teachers’ (PSTs’) views of models, a case study was conducted with fourteen PSTs in a large public university in Ankara. The study aims to provide an answer to the research question, ‘What understandings do PSTs possess about scientific models and the models used in science education?’ and to explore how they use these models in their classroom practices. Data were collected using an open-item instrument, semi-structured interviews, class observations, a...
An Investigation of preservice middle school mathematics teachers’ formative assessment approaches through lesson planning
Kaplan, Gözde; Haser, Çiğdem; Department of Elementary Science and Mathematics Education (2015)
The aim of this study was to investigate the views and practices of early childhood teachers on differentiation. In order to explore the research questions, 19 pre-kindergarten and kindergarten teachers of an International Baccalaureate (IB) world school in Turkey were interviewed about differentiation, their written curriculum documents were analyzed, and the classrooms were observed. This study was designed and conducted as a qualitative case study. As the case, an authorized International Baccalaureate P...
An Assessment of pre-service teacher education in terms of preparing teacher candidates for teaching
Eret, Esra; Ok, Ahmet; Çapa Aydın, Yeşim; Department of Educational Sciences (2013)
The purpose of the study was to investigate pre-service teacher education in Turkey in terms of preparing teacher candidates for teaching. Survey design was used and the sample included 1856 senior class teacher candidates from seven different teaching areas in seven colleges of education. Teacher Education Assessment Questionnaire (TEAQ) was prepared as the main data collection tool. To enrich the quantitative data and obtain more in-depth information, interviews were conducted with 43 teacher candidates. ...
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...
A Meta-Synthesis Study Identifying the Landscapes of Pre- and In-service Math Teachers' Knowledge in the Turkish Context
GULMEZ-DAG, Gulcin; Yıldırım, Ali (2016-01-01)
This study aims to present a synthesis of empirical studies conducted in Turkey on pre- and in-service math teachers' knowledge and to recapitulate the existing conceptualization in this particular line of research in the local context. Considering the interwoven and sophisticated nature of teachers' knowledge (Seidel & Shavelson, 2007), it sets out to enhance the understanding on what constitutes and should constitute these math teachers' knowledge by discovering the frequently studied research strands in ...
