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 Fall semester . Two student groups participated in the study . One of them , called as Experimental group , was instructed with conceptual change text oriented instruction accompanied with analogies and the other one , called as Control group , was instructed with traditionally designed chemistry instruction over a period of two weeks . To investigate the effect of the treatment , Atoms and Molecules Concept Test and Attitude Scale Toward Chemistry as a school subject were administrated to all students in both groups at the begining and end of the the treatment . To evaluate students2 science process skills , Science Process Skills Test was administrated before treatment . ANCOVA and ANOVA were used to test the hypothesis of the study . The result of the study showed that students instructed with conceptual change text oriented instruction accompanied with analogies gained higher average scores in Atoms and Molecules Concept Test than students instructed by traditionally designed instruction . In addition , students in experiental group indicated a higher positive attitude toward chemistry as a school subject .The results also indicated science process skill was a stronger predictor for the achievement of atoms and molecules concepts. Strategies that were developed and results obtained for the present study may be used by science teachers to eliminate the students2

Facilitating conceptual change in atom, molecule, ion and matter concepts Şeker, Aytül; Geban, Ömer; Department of Secondary Science and Mathematics Education (2006) The main purpose of the study was to compare the effectiveness of the conceptual chance texts oriented instruction accompanied with analagoies over traditionally designed science instruction on 7th grade students̕ understanding of atom, molecule, ion and matter concepts and their attitudes toward science as a school subject. In this study 70 seventh grade students from two classes of science course instructed by the same teacher from Battalgazi Elementary School took part. The study was conducted during 200...
Effects of conceptual change oriented instruction on understanding of gases concepts Çetin, Pınar Seda; Geban, Ömer; Department of Secondary Science and Mathematics Education (2009) 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 t...
The effect of inquiry based chemistry course on students' understanding of atom concept, learning approaches, motivation, self efficacy, and epistemological beliefs Çalışkan, İlmiye Sevilay; Geban, Ömer; Department of Secondary Science and Mathematics Education (2004) The purpose of this study was to explore the effects of inquiry-based high school chemistry course and gender differences with respect to students̕ understanding of atom concept, learning approaches, motivational goals, self-efficacy, and epistemological beliefs. In this study, 47 ninth grade students from classes of a chemistry course were taught by the same teacher in Private Yüce Science High School in the 2003-2004-spring semester were enrolled. There were two groups in the study. Two instruction method...
Explaining the relationship between high school students' selected affective characterstics and their physics achievement Doğan Tekiroğlu, Özlem; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2005) The purpose of this study is to investigate the relationship between some of selected affective characteristics of high school students related to physics lesson and their physics achievement in electricity concept. These affective characteristics of the students includes their interest in physics, importance of physics, enjoyment of extra-curricular activities related to physics, physics course anxiety, physics test anxiety, achievement motivation in physics, student motivation in physics, self-efficacy in...
Effect of conceptual change texts accompanied with analogies on understanding of chemical bonding concepts Pabuçcu, Aybüke; Geban, Ömer; Department of Secondary Science and Mathematics Education (2004) The purpose of this study was to explore the effects of CCTIA over TDCI for 9th grade students̕ understanding of chemical bonding concepts. Also, the effect of instruction on students̕ attitude toward chemistry as a school subject and the effect of gender difference on understanding of chemical bonding concepts and attitudes toward chemistry were investigated. The subjects of this study consisted of 41 ninth grade students from two classes of a chemistry course in TED Ankara High School. This study was cond...
