The present study was conducted to investigate the contribution of conceptual change texts accompanied by concept mapping instruction to 10th— grade students' understanding of the human circulatory system. To determine misconceptions concerning the human circulatory system, 10 eleventh-grade students were interviewed. In the light of the findings obtained from student interviews and related literature, the Human Circulatory System Concepts Test was developed. The data were obtained from 26 students in the experimental group taught with the conceptual change texts accompanied by concept mapping, and 23 students in the control group taught with the traditional instruction. Besides treatment, previous learning in biology and science process skills were other independent variables involved in this study. Multiple Regression Correlation analysis revealed that science process skill, the treatment, and previous learning in biology each made a statistically significant contribution to the variation in students' understanding of the human circulatory system. It was found that the conceptual change texts accompanied by concept mapping instruction produced a positive effect on students' understanding of concepts. The mean scores of experimental and control groups showed that students in the experimental group performed better with respect to the human circulatory system. Item analysis was carried out to determine and compare the proportion of correct responses and misconceptions of students in both groups. The average percent of correct responses of the experimental group was 59.8%, and that of the control group was 51.6% after treatment.

The effect of computer-based interactive conceptual change texts on 11th grade students’ understanding of electrochemistry concepts and attitude toward chemistry
Taşdelen, Uğur; Geban, Ömer; Department of Secondary Science and Mathematics Education (2011)
The purpose of the study was to investigate the effect of conceptual change oriented instruction accompanied by computer-based interactive conceptual change text (CBICCT) on 11th grade students understanding of electrochemistry and attitude toward chemistry. The study was conducted in an anatolian high school in Ankara with two science classes with 66 students in May 2009. A quasi experimental design was used. The classes was assigned to groups; one as control group and the other as experimental group. Whil...
The effect of cooperative learning approach based on conceptual change conditions on students understanding of chemical equilibrium
Bilgin, İbrahim; Geban, Ömer; Department of Secondary Science and Mathematics Education (2002)
The purpose of this study was to investigate the effects of the cooperative learning approach based on conceptual change conditions over traditional instruction on 10th grade students' conceptual understanding and achievement of computational problems related to chemical equilibrium concepts. In addition, the effects of students' performance in small group work on the students' conceptual understanding and achievement of computational problems related to chemical equilibrium was investigated. mThe subjects ...
Remediating misconceptions concerning chemical bonding through conceptual change text
Pabuçcu, Aybüke; Geban, Ömer (2006-08-01)
The purpose of this study was to explore the effects of conceptual change texts oriented instructionon 9th grade students' understanding of chemical bonding concepts. in this study, the main aim of the preparation of conceptual change texts was to activate students' prior knowledge and misconceptions and to help them to understand the chemical bonding concepts through the use of explanations. analogies and examples. Analogies were used in the conceptual change texts to deal with students' misconceptions mor...
The Impact of The Metacognitive 7E Learning Cycle on Students Epistemological Understandings
Yerdelen Damar, Sevda; Eryılmaz, Ali (2016-03-01)
This study investigated the effect of metacognitively stimulated 7E learning cycle on tenth grade students’ epistemological understandings in physics. The participants of the study included 107 (49 Female, 58 Male) tenth grade students at two public high schools in Ankara. A quasi-experimental with matching-only pretest-posttest control group design was employed. Two intact classes of each school were randomly assigned to the experimental and control group. The experimental group was instructed based on the...
The Comparative Effects of Prediction/Discussion-Based Learning Cycle, Conceptual Change Text, and Traditional Instructions on Student Understanding of Genetics
Yilmaz, Diba; Öztekin, Ceren; Sungur, Semra (Informa UK Limited, 2011-01-01)
The present study examined the comparative effects of a prediction/discussion-based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi-experimental research design of the pre-test-post-test non-equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion-based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). ...
