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, and lesson plans; and were analyzed using qualitative data analyses methods, where transcriptions from the instrument and interviews were repeatedly examined for the purpose of revealing the codes and categories about PSTs’ understandings of models, while lesson plans and class observations were examined in terms of their use of models in classroom practices. Findings showed that PSTs held fragmented views of models by having informed views in some aspects while having naïve views on other aspects. While they displayed a ‘constructivist orientation’ by acknowledging the presence of multiple models for the same phenomenon depending on scientists’ perspective or creativity involved in the production of scientific knowledge, the PSTs also expressed ‘logical positivist’ views by believing that models should be close to the real phenomena. Further, although PSTs perceived models as useful tools for teaching science and showed strong willingness towards using them, they had difficulties in integrating them in their classroom practices. These findings evidenced the intention-practice gap and the need to support PSTs in terms of pedagogical content knowledge about models.

Çakır Yıldırım, Birgül; Yılmaz Tüzün, Özgül; Department of Elementary Education (2017)
The primary focus of this study was to examine the relationships among attitudes toward energy conservation, self-determined motivation and basic psychological needs of preservice science teachers. To this end a model showing the relationship among these variables was suggested. In order to better understand the observed relationships in the model, interviews with PSTs were conducted. For the purpose of the study mixed method was used. In quantitative part of the study, 1136 preservice science teachers, who...
An Investigation of pre-service elementary mathematics teachers’ techno-pedagogical content knowledge within the context of their teaching practices
Balgalmış, Esra; Çakıroğlu, Erdinç; Department of Elementary Education (2013)
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...

Soysal, Neşe; Akar, Hanife; Department of Educational Sciences (2016)
The purpose of this study was to analyze pre-service classroom teachers’ perceived competencies on Education for Sustainable Development (ESD). For this purpose, first, attitudes of pre-service classroom teachers towards Sustainable Development (SD) were examined; then, their perceived competencies regarding ESD were investigated. Finally, the curriculum of classroom teachers was analyzed to see if it reflected learning opportunities for development of the competencies. In this study, a mixed methods sequen...
Investigating pre-service science teachers’ informal reasoning, epistemological beliefs and metacognitive awareness regarding socioscientific issues: a case for nuclear power plant construction
Öztürk, Nilay; Yılmaz Tüzün, Özgül; Department of Elementary Science and Mathematics Education (2011)
The aims of the present study were to investigate the relationship among preservice science teachers’ informal reasoning regarding nuclear power plant construction, epistemological beliefs and metacognitive awareness. Throughout 2010-2011 fall and spring semesters, a total of 674 pre-service science teachers participated in the study. Data were collected through Schommer’s Epistemological Questionnaire, Metacognitive Awareness Inventory, and Open-ended Questionnaire Assessing Informal Reasoning regarding Nu...
