The main purpose of this study is to evaluate eleventh grade Turkish pupils’ comprehension of various general chemistry concepts which in turn enables to investigate chemistry concepts which are easier and harder for students to comprehend. Examining the effect of gender and last semester chemistry course grades on pupils’ comprehension of general chemistry concepts is also within the scope of this study. The sample consists of 88 students from two Anatolian high schools in the center of Isparta, Turkey. The Chemistry Concepts Inventory (CCI), that includes non-mathematical conceptual items, was administered to students in order to collect data. Results indicated that the percentage of correct responses of students for all questions ranged from 4.5 % to 75 %. Students have troubles especially with the following chemistry concepts; “Chemical formulas and equations, macroscopic versus atomic and molecular properties, solutions, chemical reactions, properties of atoms”. Two-Way ANOVA results indicated that there is no statistically significant effect of gender and chemistry course grades on students’ comprehension of chemistry concepts.

Exploring representation of nature of science aspects in 9th grade chemistry textbooks
Esmer, Feyza; Geban, Ömer; Department of Secondary Science and Mathematics Education (2011)
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 boo...
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...
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...
The effect of 5E learning cycle model on eleventh grade students’ conceptual understanding of acids and bases concepts and motivation to learn chemistry
Çetin Dindar, Ayla; Geban, Ömer; Department of Secondary Science and Mathematics Education (2012)
The purpose of this study was to investigate the effect of 5E learning cycle model compared to traditional teacher-centered instruction on eleventh grade students’ conceptual understanding of acids and bases concepts and student motivation to learn chemistry. The measuring tools were Three-tier Acids-Bases Test (TABT) and Chemistry Motivation Questionnaire (CMQ). There were two groups, which were the experimental and traditional group, consisting of 78 students. Before the implementation, the tools were adm...
Effectiveness of instruction based on constructivist approach on students understanding of chemical bonding concepts
Uzuntiryaki, Esen; Geban, Ömer (2004-09-01)
The main purpose of this study was to investigate the effect of instruction based on constructivist approach on ninth-grade students' understanding of chemical bonding concepts and their attitudes toward chemistry as a school subject. The contribution of students' science process skills to their understanding was also investigated and gender differences in terms of understanding chemical bond- ing concepts and attitudes toward chemistry as a school subject were examined. Forty-two ninth-grade students f...
