The main purpose of this study was to compare the effectiveness of 5E learning cycle model based on constructivist theory approach over traditionally designed chemistry instruction on ninth grade students’ understanding of acid-base concepts. Sixty tenth grade students from two classes of a chemistry course taught by the same teacher in Ankara Atatürk Anatolian High School 2004-2005 spring semester were enrolled 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 the instruction based on constructivist approach. Acid-Base Concepts Achievement Test was administered to both groups as a pre-test and post-test in order to assess their understanding of concepts related to acid-base. Students were also given Attitude Scale Toward Chemistry as a School Subject at the beginning and end of the study to determine their attitudes and Science Process Skill Test at the beginning of the study to measure their science process skills. The hypotheses were tested by using analysis of covariance (ANCOVA) and t-test. The results indicated that instruction based on constructivist approach caused significantly better acquisition of scientific conceptions related to acid-base and produced significantly higher positive attitudes toward chemistry as a school subject than the traditionally designed chemistry instruction. In addition, science process skill was a strong predictor in understanding the concepts related to acid-base.

The effect of 5E learning cycle model on eleventh grade students’ conceptual understanding of acids and bases concepts and motivation to learn chemistry Çetin Dindar, Ayla; Geban, Ömer; Department of Secondary Science and Mathematics Education (2012) The purpose of this study was to investigate the effect of 5E learning cycle model compared to traditional teacher-centered instruction on eleventh grade students’ conceptual understanding of acids and bases concepts and student motivation to learn chemistry. The measuring tools were Three-tier Acids-Bases Test (TABT) and Chemistry Motivation Questionnaire (CMQ). There were two groups, which were the experimental and traditional group, consisting of 78 students. Before the implementation, the tools were adm...
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 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 ...
Effectiveness of 5E learning cycle model on students' understanding of acid-base concepts Akar, Elvan; Demircioğlu, Hüsniye; Department of Secondary Science and Mathematics Education (2005) The main purpose of this study was to compare the effectiveness of instruction based on 5E learning cycle model over traditionally designed chemistry instruction on tenth grade students2 understanding of acid-base concepts. Fifty- six tenth grade students from two classes of a chemistry course taught by the same teacher in Atatürk Anatolian High School 2003-2004 spring semester were enrolled in the study. The classes were randomly assigned as control and experimental groups. Students in the control group we...
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...
