The main aim of this study to investigate the effectiveness of conceptual change texts oriented instruction accompanied with analogies over traditionally designed chemistry instruction on overcoming 10th grade students̕ misconceptions, their understanding of rate of reaction concepts and attitude towards chemistry as a school subject. 56 tenth grade students from two classes of a chemistry course taught by the same teacher in the ATATÜRK Anatolian High school, participated in the study. This study was carried out in 2003-2004 spring semester. There were two groups in the study. Experimental group was instructed with conceptual change texts oriented instruction accompanied with analogies and the control group was instructed by traditionally designed chemistry instruction over a period of four weeks. To investigate the effect of treatment, Rate of Reaction Concepts Test and Attitude Scale Toward Chemistry as a school subject were administered to all students in both groups at the beginning and end of the treatment. To evaluate students̕ science process skills, Science Process Skills Test was administered before treatment. To test the hypothesis of the study ANOVA and ANCOVA were used. The result of the study showed that students in conceptual change texts oriented instruction accompanied with analogies got higher average scores in Rate of Reaction Concepts Test than traditionally designed chemistry instruction. Also, students in experimental group indicated a higher positive attitude toward chemistry as a school subject. In addition, science process skill was a strong predictor for the achievement related to rate of reaction concepts. Results and strategies that were developed for this study may be used by teachers to reduce and eliminate students̕ misconceptions about the rate of reaction concepts.

Facilitating Conceptual Change in Gases Concepts Cetin, Pinar Seda; Kaya, Ebru; Geban, Ömer (Springer Science and Business Media LLC, 2009-04-01) The aim of this study is to investigate the effectiveness of conceptual change oriented instruction (CCOI) over traditionally designed chemistry instruction (TDCI) on overcoming 10th grade students' misconceptions on gases concepts. In addition, the effect of gender difference on students' understanding of gases concepts was investigated. The subjects of this study consisted of 74 10th grade students from two chemistry classes. One of the classes was assigned as experimental group and the other group was as...
Facilitating Conceptual Change in Rate of Reaction Concepts Using Conceptual Change Oriented Instruction KAYA, EBRU; Geban, Ömer (2012-01-01) The purpose of this study was to investigate the effects of conceptual change-oriented instruction through demonstrations (CCOITD) on 11th grade students' understanding of rate of reaction concepts when compared to traditionally designed chemistry instruction (TDCI). The sample consisted of 69 11th grade students from two classes in a public high school. Reaction Rate Concept Test was administered to both groups as a pretest and posttest to assess students' understanding of the concepts. The data was analyz...
Conceptual change text oriented instruction to facilitate conceptual change in rate of reaction concepts Balcı, Ceyda; Boz, Yezdan; Department of Secondary Science and Mathematics Education (2006) The aim of this study is to investigate the effectiveness of conceptual change text oriented instruction accompanied with analogies over traditionally designed chemistry instruction on overcoming 10th grade students’ misconceptions, their understanding of rate of reaction concepts and their attitude towards chemistry as a school subject. 42 tenth grade students from two classes of a chemistry course taught by the same teacher at a public high school in Çanakkale involved in the study. The study was carried ...
Promoting Conceptual Change in Chemical Reactions and Energy Concepts through the Conceptual Change Oriented Instruction Ceylan, Eren; Geban, Ömer (2010-07-01) This study was designed to investigate the effectiveness of the conceptual change oriented instruction through demonstration over traditionally designed chemistry instruction on 10th grade students' understanding of chemical reactions and energy concepts and their attitudes towards chemistry as a school subject. One of the groups was defined as control group in which students were taught by traditionally designed chemistry instruction (TDCI), while the other group defined as experimental group in which stud...
FACILITATING CONCEPTUAL CHANGE IN UNDERSTANDING STATE OF MATTER AND SOLUBILITY CONCEPTS BY USING 5E LEARNING CYCLE MODEL Ceylan, Eren; Geban, Ömer (2009-01-01) The main purpose of the study was to compare the effectiveness of 5E learning cycle model based instruction and traditionally designed chemistry instruction on 10th grade students' understanding of state of matter and solubility concepts. In this study, 119 tenth grade students from chemistry courses instructed by same teacher from an Anatolian High School in Ankara, Turkey took part. This study included two groups which were randomly assigned as experimental and control groups. During teaching the topic st...
