STEM-Based Course Design: A Way to Develop Attitudes towards STEM and Science Course

The study aimed to investigate the effects of a STEM-based course design on students’ attitudes towards STEM and a science course. STEM activities were prepared per learning outcomes relating to the ‘illumination and sound technologies’ learning domain in the grade 4 science course. The study was carried out based on an experiment and control group quasi-experimental design. The study was carried out at a state school in Mersin in 2021. The experimental group of the study consisted of 32 and the control group consisted of 32 grade 4 students. STEM-based activities were performed in the experimental group. However, non-STEM activities were performed based on usual experimental setups in the control group. At the end of the study, the experimental and control group students’ attitudes towards STEM and science course were examined to determine whether there were statistically significant differences. As part of this study, student opinions on STEM were examined. A STEM Attitude Test and open-ended opinion form were used as data collection tools. Normality tests were conducted, and the homogeneity of variances was examined. Dependent and independent t-tests were conducted in quantitative data analysis and content analysis in the qualitative data analysis. The results suggested that STEM-based course design significantly increased students’ STEM attitudes and their attitudes towards science course more than the attitudes of students not exposed to STEM-based course design. In addition, students considered STEM practices fun and informative. Accordingly preparing STEM based course design for science course has been suggested

Hayvan besleme ve yem endüstrisinde biyoteknolojiden yararlanma olanakları

In recent years, biotechnology has become one of the most important phenomenons that will affect the future of mankind. Biotechnology is the use of biological organism, systems and events at the production and service areas. The aim of biotechnology in animal nutrition, to improve feedstaff production and sources and to increase evaluation of feed at the animal digestive tract. In this study, the products which are obtained by biotechnological methods such as probiotics, enzymes, ionophores, protected proteins and aminoacids and hormones were investigated and publications about the use of the products at animal nutrition were reviewed. The probiotics have special role with respect to preventing undesired microorganisms. On the other hand, when they added to the feeds, their positive effects on the feed consumption, live weight, yield and animal health have been found. Enzymes are commonly used in monogastric animals and poultry compound feeds. Poultry feed predominantly is composed of plant material, mainly cereals and vegetable proteins which contain non starchVIII polysaccharides. These feeds can not be fully digested by poultry animals. Therefore, enzyme is added to improve the nutrient availability of the feed components. External enzymes either added to cattle diets to prevent endogenic enzymes in the digestive tract. Ionophores, are used commonly for improving the feed efficiency and weight gain in ruminant nutrition. Ionophores are used for prevent coccidiosis, also it improves feed consumption and weight gain in poultry. On the other hand the products such as hormones are commonly used as growth promoters in ruminant and poultry compound feeds. Keywords: Biotechnology, Probiotic, Ionophore, Protected Protein and Amino Acid, Enzym.Son yıllarda biyoteknoloji kısa sürede insanlığın geleceğini etkileyecek en önemli olgulardan biri haline gelmiştir. Biyoteknoloji, biyolojik organizmaların, sistemlerin veya olayların, üretim ve hizmet sahalarında kullanıma aktarılmasıdır. Hayvan beslemede biyoteknoloji çalışmalarının amacı; yem maddesi üretiminin ve yem değerinin artırılması, yeni yem kaynaklarının bulunması ve yemlerin hayvan organizmasında daha iyi değerlendirilmesidir. Bu tezde, hayvan beslemede kullanılan ve biyoteknolojik yöntemlerle elde edilen probiyotikler, enzimler, iyonoforlar, korunmuş protein ve aminoasitler ve hormonlar gibi ürünler ele alınmış ve bu ürünlerin hayvan beslemede kullanımı üzerine yapılan çalışmalar biraraya getirilmiştir. Probiyotikler, arzu edilmeyen mikroorganizmaların gelişmelerini engellemesi açısından önem taşır. Ayrıca yemlere ilave edildiğinde canlı ağırlık, yem tüketimi, çeşitli verimler ve sağlık üzerineVI olumlu itkileri görülmüştür. Enzimler, monogastrik ve kümes hayvanlarının karma yemlerinde yaygın olarak kullanılmaktadır. Kanatlı yemlerinin büyük çoğunluğunu oluşturan tahıllar ve bitkisel protein yemleri, içerdikleri nişasta tabiatında olmayan polisakkaritleri nedeniyle tam olarak sindirilemezler. Bu nedenle sindirimi artırmak amacıyla yemlere enzim ilavesi yapılmaktadır. Ruminant rasyonlarma enzim ilavesi ise daha çok sindirim sisteminde mevcut enzimlerin güvence altına alınmasına yönelik olmaktadır. İyonoforlar, ruminant beslenmesinde canlı ağırlık artışı ve yemden yararlanmayı iyileştirmek amacıyla yaygın olarak kullanılmaktadır. İyonoforlar kanatlılarda koksidiyozu önlemek amacıyla kullanılmakta, canlı ağırlık artışı ve yemden yararlanmayı iyileştirmektedir. Diğer yandan, biyoteknolojik yöntemlerle elde edilen hormonlar, gelişmeyi teşvik edici madde olarak ruminantlann ve kümes hayvanlarının karma yemlerinde yaygın olarak kullanılmaktadır
