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 academic year. The classes were randomly assigned as control and experimental groups. Students in the first experimental group (n=33) received 5E learning cycle based instruction, the second experimental group (n=34) received conceptual change text based instruction and students in the control group (n=34) received traditional instruction. Two-tier multiple-choice diagnostic test, أPhotosynthesis and Respiration in Plants Concept Testؤ, was used to determine students̕ understanding of photosynthesis and respiration in plants. The test was administered to the sample of the study as pre- and post-test. Students̕ attitudes toward science and their reasoning abilities were measured by أAttitude Scale Toward Scienceؤ and أTest of Logical Thinkingؤ respectively. The hypotheses of the study were tested by using analysis of covariance (ANCOVA). The results indicated that there were significant differences among the treatment groups with respect to their understanding of photosynthesis and respiration in plants. Both 5E learning cycle based instruction and conceptual change text based instruction were found effective to eliminate 8th grade students̕ misconceptions about photosynthesis and respiration in plants. The results also showed that there were no significant differences among the treatment groups with respect to attitudes toward science as a school subject.

An implementation of problem based learning in high school biology courses
Sungur, Semra; Öztekin, Ceren; Department of Secondary Science and Mathematics Education (2004)
The main purposes of the present study included investigation of the effect of problem based learning on students2 academic achievement and performance skills in the unit of human excretory system; and students2 perceived motivation and perceived use of learning strategies. This study was carried out during 2003-2004 fall semester at an Anatolian High School in Ankara. A total of 61 tenth grade students from two biology classes of the same biology teacher were involved in the study. Two classes were randoml...
Effect of instruction using conceptual change strategies on students' conceptions of chemical reactions and energy
Ceylan, Eren; Geban, Ömer; Department of Secondary Science and Mathematics Education (2004)
The main purpose of the study was to compare the effectiveness of the conceptual change oriented instruction through demonstration and traditionally designed chemistry instruction on 10th grade students̕ understanding of chemical reactions and energy concepts and attitudes towards chemistry as a school subject. In this study, 61 tenth grade students from two classes of chemistry course instructed by same teacher from Atatürk Anatolian High School took part. The study was conducted during 2003-2004 fall seme...
Predicting academic achievement with cognitive and motivational variables
Yumuşak, Necmettin; Sungur, Semra; Department of Secondary Science and Mathematics Education (2006)
This study aimed at investigating the contribution of motivational beliefs (intrinsic goal orientation, extrinsic goal orientation, task value, control of learning beliefs, self-efficacy and test anxiety), cognitive and metacognitive strategy use (rehearsal, elaboration, organization, critical thinking, metacognitive self-regulation, time and study environment, effort regulation, peer learning, help seeking) to Turkish high school students’ achievement in biology. In this study Turkish version of the Motiva...
Improving 11th grade students' understanding of acid-base concepts by using 5e learning cycle model
Pabuçcu, Aybüke; Geban, Ömer; Department of Secondary Science and Mathematics Education (2008)
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 ...
Enhancing students' understanding of photosynthesis and respiration in plant through conceptual change approach
Yenilmez, Ayse; Öztekin, Ceren (Springer Science and Business Media LLC, 2006-03-01)
This study investigated the effectiveness of combining conceptual change text and discussion web strategies on students' understanding of photosynthesis and respiration in plants. Students' conceptual understanding of photosynthesis and respiration in plants was measured using the two-tier diagnostic test developed by Haslam and Treagust (1987, Journal of Biological Education 21: 203--211). The test was administered as pretest and posttest to a total of 233 eighth-grade students in six intact classes of the...
