The aim of this study was to examine the representation of Nature of Science (NOS) aspects in 9th grade chemistry textbooks. Two textbooks nation-wide used are analyzed, one of them is written in Turkish the other in English. These textbooks were written according to 2008-2009 education program’s curriculum. A qualitative oriented approach was employed and ethnographic content analysis was used as the methodological framework for this research as Irez (2006) has performed. Data were analyzed by means of books’ sentences. The results of the study revealed that both of two chemistry textbooks were inadequate in representing NOS aspects which are; 1. Observation and inference are distinct entities of science, 2. Science is influenced by the social and cultural environment of the scientist, 3. Science is partly the product of human creativity and imagination, 4. Scientific knowledge is tentative, empirical and theory laden, 5. There exists a distinct, non-hierarchical relationship between scientific theories and laws, 6. “There is no universal, recipe-like, method for doing science.” The frequency of presence of each aspect in books was very low.

Using the science writing heuristic approach to promote student understanding in chemical changes and mixtures Kıngır, Sevgi; Geban, Ömer; Günel, Murat; Department of Secondary Science and Mathematics Education (2011) The purpose of the present study was to investigate the effect of Science Writing Heuristic (SWH) approach on 9th grade students’ understanding of chemistry concepts and chemistry achievement in chemical changes and mixtures units. Four 9th grade classes taught by the two chemistry teachers from a public high school were selected for the study. Each teacher’s one intact class was assigned as the experimental group and the other class was assigned as the control group. Students in the experimental group were...
Effect of analogy-enhanced instruction accomponied with concept maps on understanding of acid- base concept Yılmazoğlu, Candan; Yılmazoğlu, Candan; Department of Secondary Science and Mathematics Education (2004) This study was conducted to explore the effectiveness of analogy-enhanced instruction accompanied with concept maps over traditionally designed chemistry introduction on understanding of acid-base concept and attitude toward chemistry as a school subject. 81 8th grade students from two classes of a chemistry course taught by the same teacher in Nuh Eskiyapan Primary School in Ankara in 2003-2004 fall semesters were enrolled in the study. There were two groups of students. During the treatment, students in t...
The effect of 5e learning cycle model on tenth grade students’ understanding in the particulate nature of matter, epistemological beliefs and views of nature of science Bektaş, Oktay; Geban, Ömer; Department of Secondary Science and Mathematics Education (2011) The purpose of this study is to probe whether there is a significant effect of 5E learning cycle model as compared to traditional instruction and gender on tenth grade students’ understanding in the particulate nature of matter concepts and their epistemological beliefs and to investigate whether there is an impact of 5E learning cycle model and traditional instruction in promoting the understanding of the nature of science. Pilot study was performed for the instruments in the between April and June 2009. T...
Development of new synthetic methodologies for indole derivatives Kılıklı, Ahmet Alper; Balcı, Metin; Department of Chemistry (2010) Synthesizing nitrogen containing heterocyclic compounds is one of the leading research areas throughout the organic chemistry due to their significant activities on biological systems. Among the various biologically active molecules, indole derivatives are of prime importance on the grounds of their proven clinical roles. Objective of this study is to synthesize new indole derivatives those may contribute treatment of several diseases like their analogues via a recently developed synthetic methodology. Besi...
Examination of the topic-specific nature of pedagogical content knowledge in teaching electrochemical cells and nuclear reactions Aydın, Sevgi; Friedrichsen, Patricia M.; Boz, Yezdan; Hanuscin, Deborah L. (Royal Society of Chemistry (RSC), 2014-01-01) The purpose of this study was to examine experienced chemistry teachers' pedagogical content knowledge (PCK) for two different topics in chemistry to better understand how PCK is specific to topic, including whether all components of PCK are topic-specific and to what degree. To explore the topic-specific nature of PCK, we examined two experienced teachers' PCK using a case study methodology. Multiple data collection strategies were used, including a card-sorting activity, Content Representation (CoRe), sem...
