The main purpose of this study was to investigate the effect of instruction based on constructivist approach on ninth-grade students' understanding of chemical bonding concepts and their attitudes toward chemistry as a school subject. The contribution of students' science process skills to their understanding was also investigated and gender differences in terms of understanding chemical bond- ing concepts and attitudes toward chemistry as a school subject were examined. Forty-two ninth-grade students from two classes of a chemistry course taught by the same teacher participated in the study. The classes were randomly assigned as control and experimental groups. Students in the control group were instructed by traditionally designed chemistry instruction whereas students in the experimental group were taught by instruction based on constructivist principles. This instruction was mainly grounded on Yager's (1991) constructivist teaching strategy. The results indicated that instruction based on constructivist approach caused a significantly better acquisition of scientific conceptions related to chemical bonding and produced significantly higher positive attitudes toward chemistry as a school subject than the traditionally designed chemistry instruction. Science process skill was also a strong predictor in understanding of the concepts related to chemical bonding. On the other hand, no significant effect of gender on the understanding of chemical bonding concepts and attitudes toward chemistry as a school subject was found.

Effectiveness of instruction based on constructivist approach on understanding of chemical equilibrium concepts Akkuş, Hüseyin; Kadayıfçı, Hakkı; Atasoy, Basri; Geban, Ömer (2003-06-01)
Effectiveness of constructivist approach on students' understanding of chemical bonding concepts Uzuntiryaki, Esen; Geban, Ömer; Department of Secondary Science and Mathematics Education (2003) The main purpose of this study was to compare the effectiveness of instruction based on constructivist approach over traditionally designed chemistry instruction on ninth grade students2 understanding of chemical bonding concepts. In addition, the effect of instruction on students2 attitude toward chemistry as a school subject and the effect of gender difference on understanding of chemical bonding concepts were investigated. Forty-two ninth grade students from two classes of a chemistry course taught by th...
The Effect of cooperative learning based on conceptual change approach on students’ understanding of chemical bonding concepts Eymur, Gülüzar; Geban, Ömer; Department of Secondary Science and Mathematics Education (2014) The main purpose of this study was to investigate the effects of cooperative learning based on conceptual change approach on 9th grade students’ understanding in chemical bonding concepts and their attitudes toward chemistry as a school subject compared to traditionally designed chemistry instruction. Seventy-two ninth grade students from two intact classes of chemistry course taught by same teacher in a public high school in Ankara were participated. The study was applied in the spring semester of 2011-201...
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...
EFFECTIVENESS OF CASE-BASED LEARNING INSTRUCTION ON STUDENTS' UNDERSTANDING OF SOLUBILITY EQUILIBRIUM CONCEPTS Cam, Aylin; Geban, Ömer (2013-01-01) This study was conducted to investigate the effectiveness of learning activities based on case-based learning over traditionally designed chemistry instruction on eleventh grade students' understanding of solubility equilibrium. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school instructed with same chemistry teacher. Each teaching method was randomly assigned as control and experimental group. The experimental group received case-based learnin...
