The purpose of this study was to compare the effectiveness of instruction based on 5E learning cycle model over traditionally instruction on students’ understanding of acid-base concepts. Also, the effect of instruction on students’ attitude toward chemistry as a school subject and the effect of gender difference on understanding of acid-base concepts and attitudes toward chemistry were investigated. During the second semester of 2007-2008, 130 eleventh grade students from six classes of two different high schools attended this study. The classes were randomly assigned as control and experiment groups. Students in the control groups were instructed by traditional instruction whereas students in the experimental groups were taught by 5E model. Attitude Scale Toward Chemistry as a School Subject and Acid-Base Concept Test were administered as a pre and post-tests. In addition, Science Process Skill Test and Views on Science-Technology-Society instrument was utilized. The hypotheses were tested by using two-way analysis of covariance (ANCOVA) and two-way analysis of variance (ANOVA). The results revealed that 5E Model caused a significantly better understanding of acids and bases than the traditional instruction. In addition, these models of instruction developed the similar attitude toward science as a school subject. Science process skill was a strong predictor in understanding the concepts. On the other hand, no significant effect of gender difference on understanding the acids and bases and on students’ attitudes toward chemistry as a school subject was found. The results of Views on Science-Technology-Society gave a picture of the students’ views on nature of science.

Effects of 5e learning cycle model on understanding of state of matter and solubility concepts
Ceylan, Eren; Geban, Ömer; Department of Secondary Science and Mathematics Education (2008)
The main purpose of the study was to compare the effectiveness of 5E learning cycle model based instruction and traditionally designed chemistry instruction on 10th grade students’ understanding of state of matter and solubility concepts and attitudes towards chemistry as a school subject; and students’ perceived motivation and perceived use of learning strategies. In this study, 119 tenth grade students from chemistry courses instructed by same teacher from Atatürk Anatolian High School took part. The stud...
The contribution of cognitive style and prior knowledge on sixth grade students' knowledge acquisition in polygons in drama based learning environment
Atar Koçkar, Burçin; Ubuz, Behiye; Department of Secondary Science and Mathematics Education (2010)
The purpose of this study is to investigate the contribution of cognitive style and prior knowledge on 6th grade students' knowledge acquisition in polygons in drama based learning environment. The sample of the study was composed of 112 sixth grade students from a public school in Altındağ district of Ankara. There were 9 drama based lesson plans lasting 16 lesson hours in the study. The data was collected through Group Embedded Figure Test (GEFT), and three types of knowledge tests: Declarative Knowledge ...
Modeling elementary students’ science achievement: the interrelationships among epistemological beliefs, learning approaches, and self-regulated learning strategies
Özkan, Şule; Öztekin, Ceren; Department of Secondary Science and Mathematics Education (2008)
This study aimed to explore the relationships between elementary students’ epistemological beliefs, learning approaches, self-regulated learning strategies, and their science achievement. In this investigation, a model of the potential associations among these variables was proposed and tested by using structural equation modeling. It was hypothesized that (a) students’ epistemological beliefs would directly influence their learning approaches, self-regulated learning strategies, and science achievement, (b...
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...
Improving 8th grade students' understanding of photosynthesis and respiration in plants by using 5E learning cycle and conceptual change text
Balcı, Sibel; Çakıroğlu, Jale; Department of Secondary Science and Mathematics Education (2005)
The purpose of this study was to investigate the effects of 5E learning cycle, conceptual change texts and traditional instruction on 8th grade students̕ understanding of photosynthesis and respiration in plants. Besides, the effect of instruction on students̕ attitudes toward science as a school subject was investigated. One hundred and one, 8th grade students from three classes of one elementary school in Ankara attended in this study. This study was carried out during the fall semester of 2003-2004 acade...
