Eurasian Journal of Physics and Chemistry Education , 2010,
Abstract: The aim of this study is to determine whether the understandings levels of prospective science teachers on the nature of science are dependent on differences in grade level and gender. This study utilizes VOSTS scale, which was developed by Aikenhead and Ryan, and adapted by Chan in order to determine viewpoints of prospective teachers on the nature of science. Eighteen multiple-choice questions from this scale were translated and adapted into Turkish from English by researchers, who also conducted a preliminary work on the validity and reliability of the scale. The adapted scale was applied to 80 prospective science teachers, who were not included in the sample of this study and the reliability coefficient of the scale was found to be 0.81. Then the scale is applied to 201 prospective teachers who are enrolled in the science education program. The statistical analysis of the results demonstrated that while views of the prospective science teachers on nature of science are not significantly correlated with differences in grade level and gender, there were significant variations among these views. In this study, it was determined that prospective teachers had certain misconceptions on nature of science with respect to specific issues including hierarchical relationships between concepts of hypothesis, theory, law, and universal scientific method; that they relied predominantly on positivist paradigm; and that they espoused the traditional approach to science in understanding and interpreting nature of science.

Journal of Turkish Science Education , 2007,
Abstract: The purpose of this study was to determine how both 2000 and 2004 science curricula were evaluated by prospective teachers. For this purpose, prospective teachers were asked to compare the content in both science curricula. Comparison criteria were not provided for the prospective teachers; it was deemed that they could determine their own criterion in the context that they can express their own thoughts freely and unrestrictedly. In this study, third year university students in the science education department, were selected as a sample (n=60) who was deemed to have sufficient knowledge about how to evaluate and how to use a curriculum since they had attended Science Laboratory Applications-I-II, Subject Methodology-I, School Experience-I courses respectively. Another reason for selection of this sample was that they were willing to make such an evaluation. The results obtained from the comments of prospective teachers were important since their views reflected their thoughts. When the thoughts of prospective teachers are taken into consideration, it can be expressed that they have more positive thoughts about 2004 curriculum.

Journal of Kirsehir Education Faculty , 2008,
Abstract: In this research, perceptions of prospective teachers in relation to Civil Cervant Selection Exam (KPSS) were investigated. A researcher-made questionnaire containing 28 closed-ended items were administered to 507 junior and senior prospective teachers. The results showed that the KPSS was so important for the prospective teachers, however, this exam system wear them down economically, socialy, and psychologically. Besides, the exam was not favourite system in selecting quality teachers and it caused anxiety on prospective teachers. Lastly, the pedagocial courses in education faculties should paralelly be designed to KPSS.

Necatibey Faculty of Education, Electronic Journal of Science and Mathematics Education , 2007,
Abstract: The aim of this study is to determine conceptual understanding level of prospective science teachers on enzymes before, after and six month later traditional instruction. A conceptual understanding test consisted of three open ended questions was prepared and administered as pre-, post- and delayed post test to 88 prospective teachers. Then, in order to reveal opinions of the students in more details, semi-structured interviews were conducted to 19 teacher candidates. At the end of the study, it was reached that prospective science teachers have certain sorts of difficulties in understanding enzymes, and that traditional instruction is insufficient on providing conceptual understanding. It was revealed that candidates have misconceptions particularly on enzyme activity mechanism and other specifics of enzymes. In the light of the findings, it was suggested that activities based on constructivist approach and conceptual change model should be used for assembling of teaching environment.
