The current study aimed to investigate the effect of using metacognitive strategies embedded in explicit–reflective NOS instruction to improve NOS understanding of pre-service science teachers. Metacognitive Awareness Inventory (MAI) (Schraw & Dennison, 1994) and Views of Nature of Science Questionnaire (VNOS-C) (Lederman et al., 2001) were used both at the beginning and at the end of the study as a pre-test–post-test, comparison group, quasi-experimental design. A total of 33 pre-service science teachers (PSTs), 24 were female and 9 were male agreed to join the study voluntarily. These students were selected for this study while they were enrolling at their 5th semester in which they attended Methods of Teaching Science I course offered by the faculty of education at Middle East Technical University. Participants were divided into two groups namely comparison and intervention group. Explicit reflective NOS instruction was used in both groups, but metacognitive strategies additionally used in intervention group. Data analysis demonstrated that explicit reflective NOS instruction enhanced the development of understanding of NOS in both groups. Results also showed that metacognitive strategies improved the metacognitive awareness of intervention group participants. Although four of these metacognitive strategies and explicit reflective NOS instruction in present study provided a substantial increase in NOS understandings of PSTs in intervention group, chi-square analysis showed statistically no significant difference between comparison and intervention group participants’ post-test results.

The Effects of a professional development program on physics teachers’ classroom practices
Oktay, Özlem; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2015)
The purpose of the study is to examine the effects of a professional development (PD) program on in-service physics teachers’ classroom practices. Changes in teachers’ practices were investigated in terms of four dimensions: content/skill/ misconception, teaching strategy, material/technology, and assessment. Qualitative research methodology was used in the study, and a case study was combined with action research. Data were collected from seven participating teachers (1 male, 6 female) and their 9th grade ...
Development of pre-service science teachers’ nature of science views and nature of science instructional planning within a contextualized expilicit reflective approach
Bilican, Kader; Çakıroğlu, Jale; Öztekin, Ceren; Department of Elementary Education (2014)
The main focus of the study was to explore pre-service science teachers’ understanding of NOS and translation of this understanding into their instructional planning for teaching NOS within the contextualized explicit reflective NOS based approach. The study, first investigated pre-service science teachers’ development of NOS views as a result of explicit reflective NOS instruction in the context of HOS based science method course, which was designed to improve pre-service science teachers’ both NOS views a...
Antecedents of nature of science teaching intention: testing the applicability of the theory of planned behavior
Akyol, Gülsüm; Öztekin, Ceren; Sungur, Semra; Department of Elementary Education (2015)
This study tested the applicability of the Theory of Planned Behavior (TPB) in explaining pre-service science teachers’ intentions to integrate NOS into their science instruction. Data were collected from 1172 senior pre-service science teachers through administration of Intention to Integrate NOS Questionnaire. On the basis of TPB, a model was proposed suggesting that intention to integrate NOS into science instruction is determined by attitude toward behavior, subjective norm (SN), and perceived behaviora...
The effect of conceptual change approach on students' understanding of solubility equilibrium concepts
Önder, İsmail; Geban, Ömer; Department of Secondary Science and Mathematics Education (2006)
The main purpose of this study was to compare the effectiveness of instructions one based on conceptual change approach and the other based on traditional chemistry instruction on tenth grade high school students’ understanding of solubility equilibrium concept. In addition, students’ attitudes toward chemistry as a school subject and toward conceptual change texts were investigated. Moreover, students’ science process skills were also investigated. 125 tenth grade students from four classes of a chemistry ...
The Effect of history of science instruction on elementary students' scientific literacy
Cansız, Mustafa; Sungur Vural, Semra; Öztekin, Ceren; Department of Elementary Education (2014)
The purpose of this study is to investigate the effectiveness of history of science instruction on elementary students' scientific literacy. Specifically, the effectiveness of history of science instruction over curriculum-oriented instruction was examined in terms of four central components of scientific literacy, which are science process skills, understanding of human circulatory system concepts, attitudes toward science, and nature of science views. A total of 95 sixth-grade students from four classes p...
