Öğe A cross-cultural study on freshmen's knowledge of genetics, evolution, and the nature of science(Sci Methodical Ctr-Sci Educologica, 2014) Sorgo, Andrej; Uşak, Muhammet; Kubiatko, Milan; Fancovicova, Jana; Prokop, Pavol; Bahar, MehmetThe purpose of this study was to measure the freshmen's level of knowledge about genetics, evolution, human evolution, the nature of science, and opinions on evolution and the presence of non-scientific explanations among Czech, Slovakian, Slovenian and Turkish students. Determination of prior knowledge and pre-conceptions about these issues is important because they are filters to learning other related concepts. The results are going to be a starting point for developing teaching strategies concerning Darwinian evolution and preparing prospective science teachers for working with students in national and international contexts. A total of 994 first-year university students from the Czech Republic (276; 27.8%), Slovakia (212, 21.3%), Slovenia (217, 27.3%) and Turkey (235, 23.6%) participated in this study. The findings can be summarized as follows: knowledge especially that of the nature of science at the freshmen level was seriously flawed. Non-scientific explanations were present in high percentages. Both were regarded as barriers towards scientific reasoning and acceptance of general human evolution especially for students expressing orthodox religious beliefs.Öğe Science student teachers' ideas of the heart(Sci Methodical Ctr-Sci Educologica, 2008) Bahar, Mehmet; Özel, Murat; Prokop, Pavol; Uşak, MuhammetThe purpose of this study was to find out the level of science student teachers' understanding about the internal structure of the heart. The drawing method was applied to achieve this purpose with 120 third year science student teachers. The analysis of their drawings revealed that the majority of the science student teachers hove several misconceptions as well as inadequate knowledge in terms of the heart's internal structure. The importance of the findings was critically analysed in the light of the literature, and some suggestions were proposed to remedy the emerged problems.Öğe SLOVAKIAN AND TURKISH STUDENTS' FEAR, DISGUST AND PERCEIVED DANGER OF INVERTEBRATES(Hacettepe Univ, 2011) Prokop, Pavol; Usak, Muhammet; Erdogan, Mehmet; Fancovicova, Jana; Bahar, MehmetHuman perceives invertebrates less positively than vertebrates because they are small and behaviourally and morphologically unfamiliar. This cross-cultural research focused on Slovakian (n=150) and Turkish (n=164) students' fear, disgust and perceived danger regarding 25 invertebrates [including 5 disease relevant adult insects, 5 ectoparasites, 5 endoparasites, 5 disease irrelevant adult insects and 5 insect larvae/earthworm]. A subsample of Slovakian children was asked for taxonomic identification of these animals. It was found that Turkish students rated higher in all three dimensions fear, disgust and dangerousness, compared with Slovakian students. Gender difference favouring higher score of females were found only among Slovakian students and these differences were observed for potentially harmful animals. This implies that females were able to distinguish between more and less dangerous animals. It was neither detected any effects of owning animals on students' ratings, nor found any correlation between identification skills and rating scores.Öğe Slovakian and Turkish students’ fear, disgust and perceived danger of invertebrates(2011) Prokop, Pavol; Uşak, Muhammet; Erdoğan, Mehmet; Fancovicova, Jana; Bahar, Mehmetİnsanoğlu omurgasız hayvanları omurgalı hayvanlara göre daha az olumlu algılamaktadır. Çünkü bu hayvanlar davranış ve morfolojik yapı olarak çok alışılmamışlardır. Bu kültürlerarası çalışma Slovak (n=150) ve Türk (n=164) öğrencilerin 25 omurgasız canlı ile ilgili algılanan tehlike, korku ve nefretlerini araştırmaktadır. Türk öğrencilerden farklı olarak, Slovak öğrencilere bu canlıların sınıflandırmaları üzerine sorular sorulmuştur. Slovak öğrencileri ile karşılaştırıldığında, Türk öğrencileri daha yüksek düzeyde korku, nefret ve tehlike algısına sahiptirler. Kızlar lehine cinsiyet farkı sadece Slovak öğrenciler arasında ve potansiyel olarak tehlikeli olan canlılar için gözlemlenmiştir. Bu durum kız öğrencilerin tehlikeli hayvanları az veya çok ayırt edemediğini göstermiştir. Herhangi bir ev hayvanına sahip olma ile öğrencilerin görüşleri arasında bir ilişki bulunamamıştır. Ayrıca, sınıflandırma becerileri ile öğrencilerin görüşleri arasında da bir ilişki bulunamamıştır.Öğe Student teachers' knowledge of and attitudes toward chemical hormone usage in biotechnology(Academic Journals, 2008) Özden, Mustafa; Uşak, Muhammet; Prokop, Pavol; Türkoğlu, Aziz; Bahar, MehmetApplication of modern technologies may be problematic especially if they possess health risks to humans and/or when humans are not aware about these technologies. In this study we investigated non-major student teachers' attitudes to and knowledge of the chemical hormone usage, a controversial topic in the field of modern biotechnology. Although students' knowledge was considered to be limited (8 of 14 items were correctly responded by more than half of participants), we failed to find any differences in mean scores with respect to age or gender. In contrast, females showed less favourable attitudes toward chemical hormones than males. These gender differences were found in topics that represented relatively higher risk to human health which supports the "gender paradox hypothesis" which proposes that females have more tentative attitudes towards new products than males because they buy food for children.
