The main purpose of the present study was to investigate the effect of case-based instruction based on conceptual change conditions to overcome 10th grade students’ misconceptions related to gas concepts. Moreover, the effect of this method on students’ attitudes toward chemistry and their perceived motivation was explored. The study was carried out during the 2008-2009 academic year at both a state high school and an Anatolian high school. A total of 128 tenth grade students were the participants of the study. One of the classes of the same chemistry teacher was randomly assigned as experimental group and one of them was control group in each school. Students in experimental groups were instructed by case-based learning based on conceptual change conditions while the control group students received traditionally designed chemistry instruction. Gas Concept Test, Attitude toward Chemistry and Motivated Strategies for Learning Questionnaire were administered to both groups of students as pretest and posttest to determine the students’ misconceptions and their understanding of gas concepts, their attitude toward chemistry and perceived motivation. Two two-way ANOVA based on gain scores were used to assess the effect of case-based learning on students’ understanding of gas concepts and attitudes toward chemistry. In addition, the effect of case-based learning on students’ perceived motivation was investigated by MANOVA based on gain scores. The results revealed that case-based learning was an effective method for overcoming students’ misconceptions about the gas concepts and promoting their attitudes and motivation towards chemistry in Anatolian high school.

Effectiveness of case-based learning instruction on students’ understanding of solubility equilibrium concepts
Çam, Aylin; Geban, Ömer; Department of Secondary Science and Mathematics Education (2009)
The main purpose of this study is to compare the effectiveness of case- based learning method instruction over traditional method instruction on eleventh grade high school students’ understanding of solubility equilibrium concepts. In addition, students’ attitudes toward chemistry as a school subject and students’ epistemological beliefs were investigated. Sixty-two eleventh grade students from two classes of a chemistry course taught by the same teacher in Atakent High School in 2007-2008 spring semesters ...
A modeling study : the interrelationships among elementary students’ epistemological beliefs, learning enviroment perceptions, learning approaches and science achievement
Uysal, Emel; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2010)
This study is aimed to explore the relationships among elementary students’ epistemological beliefs of science, perceptions of learning environments, learning approaches and science achievement. For this purpose, a model of the associations among these variables was proposed and tested by structural equation modeling. In this model, it was hypothesized that a) students’ perceptions of their learning environments would directly influence their epistemological beliefs of science and learning approaches, b) st...
The roles of affective, socioeconomic status and school factors on mathematics achievement: a structural equation modeling study
Mert Kalender, Özge; Bulut, Safure; Department of Secondary Science and Mathematics Education (2010)
The purpose of the present study was to investigate the effects of socioeconomic status, school factors (classroom climate, classroom activities) and affective variables (motivation, self-efficacy, mathematics anxiety, beliefs about the nature of mathematics and teaching of mathematics, students’ perceptions of their teachers and parents’ attitudes toward them) on mathematics achievement with 9th grade students in Ankara. For this purpose, structural equation modeling techniques were used. In the study, the...
Effect of conceptual change approach accompanied with concept mapping on understanding of solution concepts
Kondakçı, Esen; Geban, Ömer (Springer Science and Business Media LLC, 2005-07-01)
The purpose of this study was to investigate the effect of conceptual change texts accompanied with concept mapping instruction, compared to traditional instruction (TI), on 8th grade students' understanding of solution concepts and their attitudes toward science as a school subject. Solution Concept Test was developed as a result of examination of related literature and interviews with teachers regarding their observations of students' difficulties. The test was administered to a total of 64 eighth grade s...
Effect of cooperative learning based on conceptual change conditions on motivation and understanding of reaction rate
Taştan, Özgecan; Boz, Yezdan; Department of Secondary Science and Mathematics Education (2009)
The present study mainly focuses on the effect of cooperative learning based on conceptual change conditions to remedy 11th grade students’ misconceptions related to reaction rate. Also, effect of this method on their motivation was investigated. A total of 110 eleventh grade students participated in the study. Two schools in Ankara and two classes being instructed by the same teacher in each school were included in the sample. One of the classes was randomly assigned as a control group instructed by tradit...
