The main purpose of the study was to compare the effectiveness of conceptual change oriented instruction accompanied with computer animations and traditionally designed chemistry instruction on 10th grade students’ understanding, achievement and retention of gases concepts and attitudes towards chemistry as a school subject. Also students’ views about nature of science were investigated. Quasi experimental design was used in this study. 67 tenth grade students from two intact classes of a chemistry course taught by the same teacher in Sokullu High School were enrolled. The hypotheses were tested by using analyses of covariance and two- way analyses of variance. The results indicated that instruction based on conceptual change approach caused significantly better acquisition of the scientific conceptions, achievement and retention related to gases concepts than traditionally designed chemistry instruction. Science process skill was determined as a strong predictor in the concepts related to gases. Moreover instruction based on conceptual change approach improved students’ attitudes as a school subject. However no significant effect of gender difference on students’ understanding, achievement and attitudes toward chemistry as a school subject was found. Finally experimental group students’ views about some characteristics of nature of science were determined as more realistic than control group students.

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...
Effect of conceptual change oriented instruction accompanied with cooperative group work on understanding of acid-base concepts Ayhan, Arzu; Geban, Ömer; Department of Secondary Science and Mathematics Education (2004) The main purpose of this study was to compare the effectiveness of conceptual change oriented instruction accompanied with cooperative group work and traditionally designed instruction for removing misconceptions related to acid-base concepts. In this study 33 tenth grade students from two classes from METU Development Foundation Private School in the spring semester of 2003-2004 participated. There were two groups in the study. Students in experimental group received conceptual change oriented instruction ...
Implementation of conceptual change oriented instruction using hands on activities on tenth grade students' understanding of gases concepts İpek, İnciser; Kondakçı, Esen; Department of Secondary Science and Mathematics Education (2007) The purpose of this study was to compare the effectiveness of the conceptual change oriented instruction using hands-on activities and traditionally designed chemistry instruction on 10th grade students’ understanding of gases concept. Also, the effect of instruction on students’ attitude toward chemistry as a school subject was investigated. The sample of the study consisted of 59 tenth grade students from two chemistry classes in a public high school. This study was conducted during the 2006-2007 fall sem...
Conceptual change text oriented instruction to facilitate conceptual change in atoms and molecules Günay, Barış; Geban, Ömer; Department of Secondary Science and Mathematics Education (2005) 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 students2 misconceptions, their understanding atoms and molecules concepts and attitude towards chemistry as a school subject . 45 tenth grades students from two classes of a chemistry course taught by the same teacher in Elmadag High School prticipated in the study that was carried out in 2004 62005 ...
Effect of cooperative learning based on conceptual change conditions on seventh grade students' understanding of classification of matter and physical and chemical changes Erdemir (Özdemir), Arzu; Özgenel, Lale; Department of Secondary Science and Mathematics Education (2006) The main purpose of this study was to compare the effectiveness of the cooperative learning based on conceptual change conditions and traditionally designed science instruction on 7th grade students̕ understanding of chemical and physical changes and classification of matter concepts and attitudes toward science as a school subject. In this study 102 seventh grade students from four classes of a Science Course instructed by the two teachers from ODTÜ G.V. Özel Ilkögretim Okulu took part. One of the classes ...
