Scharmann, Lawrence C.; Smith, Mike U. – Science Education, 2001
Responds to "Understanding Nature of Science as Progressive Transitions in Heuristic Principles" by Mansoor Niaz. Concludes that the historical vignettes provided by Niaz provide interesting insights into the nature of science but that the proposed characterizations do not help distinguish things that are more scientific from things that are less…

Niaz, Mansoor – Interchange: A Quarterly Review of Education, 2011
The objective of this study was to facilitate inservice high school and university teachers' understanding of the difference between the terms "hypothesis" and "prediction." The context for understanding these terms was Columbus's discovery of America (as in the previous study). Control group teachers (N = 94) were evaluated before the discussion…

Niaz, Mansoor – Routledge, Taylor & Francis Group, 2010
How teachers view the nature of scientific knowledge is crucial to their understanding of science content and how it can be taught. This book presents an overview of the dynamics of scientific progress and its relationship to the history and philosophy of science, and then explores their methodological and educational implications and develops…

Niaz, Mansoor – Teaching and Teacher Education: An International Journal of Research and Studies, 2010
Kuhn (1970) considered textbooks to be good "pedagogical vehicles" for the perpetuation of "normal science". Collins (2000) has pointed out a fundamental contradiction with respect to what science could achieve (create new knowledge) and how we teach science (authoritarian). Despite the reform efforts, students still have naive views about the…

Niaz, Mansoor – Science & Education, 2009
The objective of this study is to facilitate progressive transitions in chemistry teachers understanding of nature of science in the context of historical controversies. Selected controversies referred to episodes that form part of the chemistry curriculum both at secondary and university freshman level. The study is based on 17 in-service…

Niaz, Mansoor; Cardellini, Liberato – Journal of Chemical Education, 2011
Bohr's model of the atom is considered to be important by general chemistry textbooks. A shortcoming of this model was that it could not explain the spectra of atoms containing more than one electron. To increase the explanatory power of the model, Sommerfeld hypothesized the existence of elliptical orbits. This study aims to elaborate a framework…

Niaz, Mansoor – Instructional Science: An International Journal of the Learning Sciences, 2008
The objective of this study is to facilitate in-service chemistry teachers' understanding of nature of science and what "ideas-about-science" can be included in the classroom. The study is based on 17 in-service teachers who had registered for a 11-week course on "Epistemology of Science Teaching" as part of their Master's degree program. The…

Niaz, Mansoor – Journal of Philosophy of Education, 2008
Recent research shows that research programmes (quantitative, qualitative and mixed) in education are not displaced (as suggested by Kuhn) but rather lead to integration. The objective of this study is to present a rationale for mixed methods (integrative) research programs based on contemporary philosophy of science (Lakatos, Giere, Cartwright,…

Niaz, Mansoor – Teaching and Teacher Education: An International Journal of Research and Studies, 2008
Constructivism in science education has been the subject of considerable debate in the science education literature. The purpose of this study was to facilitate chemistry teachers' understanding that the tentative nature of scientific knowledge leads to the coexistence and rivalries among different forms of constructivism in science education. The…

Costu, Bayram; Ayas, Alipasa; Niaz, Mansoor – Instructional Science: An International Journal of the Learning Sciences, 2012
This article reports on the development of a Predict-Observe-Explain, POE-based teaching strategy to facilitate conceptual change and its effectiveness on student understanding of condensation. The sample consisted of 52 first-year students in primary science education department. Students' ideas were elicited using a test consisting of five probe…
