The purpose of this study was to identify the relative predictive influences of prior knowledge, meaningful learning orientation, formal reasoning ability and mode of instruction on understanding in photosynthesis and respiration in plants concepts. Two hundred thirty three 8th grade students from six classes of one elementary school in Ankara participated in this study. The study was carried out during the 2004-2005 Fall semester. Students in the experimental group (N=117) received conceptual change instruction, and the students in the control group (N=116) received traditional instruction. Two-tier multiple choice diagnostic test, أPhotosynthesis and Respiration in Plants Concept Testؤ developed by Haslam and Treagust (1987), was used to determine students̕ understanding of photosynthesis and respiration in plants concepts. The test was administered to the sample prior to the treatment as pre-test, and after the treatment as post-test. The pre-test scores were used as prior knowledge of students. Students̕ reasoning abilities were measured by the أTest of Logical Thinkingؤ and their learning orientations were measured by أLearning Approach Questionnaireؤ. The results of the study indicated that students held several misconceptions concerning photosynthesis and respiration in plants concepts. Significant differences between the experimental group and control group with respect to understanding of the concept were found in favor of experimental group. The main predictor of achievement in the experimental group was students̕ prior knowledge, while it was reasoning ability in the control group. Meaningful learning orientation accounted for a small amount of variance in the experimental group but it did not contribute to understanding on post-test scores in traditional group.

Investigating students motivational traits in science
Yavuz, Fatma; Öztekin, Ceren; Department of Elementary Science and Mathematics Education (2006)
The aim of this study was to investigate the elementary school students’ motivational traits (achiever, curious, conscientious and social) in science. More specifically present study examined the effects of gender, grade level and location of the school on elementary school students’ motivational traits. The data in the main study was collected by Motivational Pattern Questionnaire from randomly selected 8 classes of randomly selected 15 schools in five districts of Ankara. A total of 3685 students (1927 fe...
The effect of instruction with analogy-enhanced model on ninth grade students' function achievement and attitudes toward mathematics
Akman, Caner; Bulut, Safure; Department of Secondary Science and Mathematics Education (2005)
This study was conducted to investigate the effect of analogy-enhanced instruction on students̕ achievement in function and attitudes toward mathematics. The study was conducted with 63 ninth grade students in one of the public high schools in Konya, Turkey during Spring 2005 semester. The experimental group received instruction with analogy-enhanced model. The control group received instruction with traditional method. The matching-only pre-test- post-test control group design was used in the study. The fo...
The Role of Metacognition in Facilitating Conceptual Change
Yürük, Nejla; Beeth, Michael E; Özdemir, Ömer Faruk (2003-03-31)
This paper describe the intertwined nature of metacognition and conceptual change and proposes a taxonomy that classifies the types of metacognitive knowledge and activities that are likely to influence the change in students' conceptions. The initial conceptual change model is introduced to provide background and context for the theoretical argument, and a summary of the other theoretical approaches is drawn to explain the change in students' conceptions. The definition of metacognition is presented along ...
Examining middle school students' understanding of the nature of science
Çelikdemir, Meliha; Çakıroğlu, Jale; Department of Elementary Science and Mathematics Education (2006)
The aim of this study is to investigate the elementary school students’ understandings of the nature of science (NOS). A total of 1949 students (1026 sixth graders and 923 eighth graders) from six different elementary schools participated in the study. “Nature of Science Questionnaire for Elementary Level (E-NOS)” questionnaire, adapted from Views on Science-Technology-Society (VOSTS) developed by Aikenhead, Fleming and Ryan (1989) and Views on Nature of Science (VNOS-D) constructed by Lederman, Adb-El-Khal...

Kaynar, Devrim; Çakıroğlu, Jale; Department of Educational Sciences (2007)
The purpose of this study is to investigate the effectiveness of 5E learning cycle on sixth grade students’ understanding of cell concepts, their attitude toward science and their scientific epistemological beliefs In this study the data were collected using ‘Epistemological Belief Questionnaire’ developed by Conley, Pintrich, Vekiri and Harrison (2004), the ‘Cell Concept Test’ developed by researcher and ‘Science Attitude Questionnaire’ developed by Geban, Ertepınar, Yılmaz and Şahbaz (1994). The instrumen...
