Item Open Access Application of food fermentation practical work in classes(2021-08) Yılmaz, Burçin ArslanThis study investigates the integration of food fermentation practical work into national and international curricula and teachers’ perceptions of its implementation in classes. Content analysis was used to determine the incorporation of food fermentation practical work into IBDP, IGCSE, MoNE biology and MoNE science curricula to develop a framework. Furthermore, a food fermentation workshop is organized for teachers and their curriculum integration study in the workshop used for triangulation. After the workshop, semi-structured interviews were used to gather data about teachers’ perceptions on the application of practical work of food fermentation in classes. Food fermentation practical work was found to be applicable in 75% of the MoNE biology curriculum units, and in 67% and 62% of the IBDP and IGCSE biology curricula, and 36% of the MoNE science curriculum. The findings suggest that all teachers’ views about the use of food fermentation practical work in classes were positive in terms of contribution of practical work on learning, making abstract topic more permanent, improving students’ recall level and eliminating misconceptions of the topic, and improving students’ manipulative, creativity, communication, responsibility skills. It is found that teachers who have resources such as laboratories, allowed time in curriculum for practical work, the support of school administrations, availability of ready-made materials and in-service trainings on practical work, are more willing to implement food fermentation practical work in their classes. Moreover, practical studies of food fermentation were found appropriate for extracurricular activities and interdisciplinary projects by the teachers.Item Open Access Fen eğitiminde 'bilimsel açıklama' ve önemi(KEFAD, 2016) Karaaslan, E. H.; Ayas, AlipaşaBu çalışmanın amacı bilimsel açıklama kavramını farklı teorik yaklaşımlar çerçevesinde incelemektir. Tümdengelimli-yasa bağımlı açıklama modeli, İstatistiksel/olasılıklı açıklama modeli, Nedensel model, Pragmatik model ve Kanıt temelli model temelinde bilimsel açıklama kavramı bu çalışma kapsamında tanımlanmaya çalışılmıştır. Çalışma sonunda elde edilen tanımlar karşılaştırıldığında, bu tanımların birbirlerinden oldukça farklı olduğu ve farklı alanlarda farklı şekillerde bilimsel açıklama yapıldığı görülmüştür. Bu bulgu bilimsel açıklama ile ilgili genel, evrensel bir tanımın yapılamayacağını göstermiştir. Örneğin sıcak suya batırılmış bir parça demirin genleşme sebebinin açıklanması neden-sonuç ilişkisi içeren cümleler zinciri kullanılarak yapılmaktadır. Buna karşılık bir ilacın bir hastalığı iyileştirme olasılığı birtakım istatiksel verilere dayandırılarak yapılmaktadır. Bu durum farklı disiplinlerde farklı şekillerde açıklamalar yapılmasına neden olmaktadır. Dolayısıyla bilimsel açıklamanın tanımı bir disiplinden diğerine farklılık göstermektedir. Bununla birlikte, bilimsel açıklamanın eğitimdeki önemi ve bilimsel açıklama ile argüman kavramları arasındaki farklar bu çalışmanın son bölümünde tartışılmıştırItem Open Access Resolving the dilemma of international school cirriculum: the case of biology(Eurasia Publishing House, 2014) Sagun, S.; Corlu, M. S.The purpose of the current study is to explore the predictors of the Diploma Program scores in biology to resolve the dilemma regarding which international school curriculum is better to prepare students for the Diploma Program. A purposive sample of 135 high school students was drawn from a private international school in Turkey. Data was analyzed with a multiple regression approach. A statistically significant and relatively strong relationship was found between the Diploma Program scores in biology and the International General Certificate of Secondary Education science exam scores.Item Open Access Which preparatory curriculum for the International Baccalaureate Diploma Programme is best? The challenge for international schools with regard to mathematics and science(Springer Netherlands, 2014) Corlu, M. S.There are two mainstream curricula for international school students at the junior high level: the International Baccalaureate (IB) Middle Years Programme (MYP) and the Cambridge International General Certificate of Secondary Education (IGCSE). The former was developed in the mid-1990s and is currently being relaunched in a 21st-century approach. The latter programme of study was developed by University of Cambridge International Examinations in 1985 and has become popular in recent years among British domestic and international schools worldwide due to the clarity of its learning content. The prevailing uncertainty about which curriculum is best to prepare students for the IB Diploma Programme represents a challenge for international schools. The purpose of the current study is to develop a methodology through causal models which can explain the relationship between student performance in the IGCSE and the Diploma Programme with regard to mathematics and science. The data evaluated here consisted of external examination scores of students who attended a private international high school between the years 2005 and 2012. Two structural equation models were developed. The first model employed a maximum likelihood estimation, while the second model used a Bayesian estimation with a Markov Chain Monte Carlo method. Both models fit the data well. The evidence suggests that the IGCSE provides a good foundational preparation for the Diploma Programme in mathematics and science.
