“…Combined with these are efforts to survey school pupils' ideas of specific health education concepts and create effective interventions (e.g. Acheampong et al 2003;D'Agostino 2018;Günter and Demir 2018;Hagay and Baram-Tsabari 2011;Mafra et al 2015;Mallya et al 2012;Moreno et al 2018;Reeve and Bell 2009;Romine et al 2013). The current study's rationale reflects and contributes to this 'healthy science' literature, the broad aim of which is the eventual improvement of health outcomes by considering how science lessons could enhance these particular aspects of scientific literacy.…”

In this exploratory study, a sample of 20 four-year-olds took part in structured interviews in order to assess their biological knowledge of how the human body processes a food that they perceived to be fattening. There were two main outcomes to the study. First, the sample demonstrated knowledge of the digestive processes of ingestion, digestion/distribution and terminal digestive events that was broadly analogous to previous studies, and included a number of misconceptions. A minority of children could apply biological reasoning to make holistic sense of a series of linked, abstract physiological events. Data also revealed that young learners' models of distribution of food away from the gut might be more sophisticated than previously reported, although none of the sample could provide any mechanism for distribution. Second, data were analysed quantitatively to give performance scores which were compared with children's standardised body mass indices. Children of healthy weight displayed more accurate scientific knowledge of digestive processes than their overweight peers at statistically significant levels. Specifically, the healthy weight children had attained a more holistic understanding of these processes. This potentially has consequences for early years biology education since findings indicate, at a tentative level, that young, overweight children could be considered as having a distinctive special educational need. We propose that there may be a possible way forward for addressing the issues of overweight and obesity in young children by improving their understanding of digestive processes. These outcomes are aligned with calls in the literature for school science education to become more focused on aspects of scientific literacy such as health education. Further studies are recommended using larger samples from more diverse populations.

“…Research also shows adolescents being uncertain of their DS needs and relying on their mother's opinion as well as being unaware of any potential health risks regarding the consumption of DS (O'Dea, 2003). There are only a few studies concerning adolescents' knowledge on nutritional supplements and/or their opinions of perceived health benefits of using DS (Dorsch and Bell, 2005;Günter and Demir, 2018;Little et al, 2002;O'Dea, 2003;Thompsen et al, 1987). These studies show that adolescents' nutrition knowledge on the need for DS varies greatly, and is often inadequate.…”

Purpose -The purpose of this paper is to assess the socioscientific issue (SSI) method as a way of improving seventh graders' nutrition know-how on dietary supplements (DS), and to describe how students experience learning nutritional issues through the SSI method. Design/methodology/approach -Participants were seventh graders from three different classes (n ¼ 43). Health education intervention lasted 7 h and it embodied the three-staged model: the scenario, the inquiry and the decision-making stages. The study was qualitative in nature. The data were collected through a questionnaire before and after the intervention. The data were analyzed using summative content analysis. Findings -Intervention tended to deepen students' know-how on vitamins and rational use of DS. Students' experiences of learning nutritional issues through the SSI method were generally positive. The scenario stage was considered current and authentic. The inquiry stage and decision-making stage helped in understanding the societal connections between the study task and the rational use of DS. Practical implications -SSI method enhances students' knowledge about the rational use of DS. E-learning environment gave students possibilities to work collaboratively. Especially, possibilities to discuss with peers and share own experiences supported learning. Originality/value -To solve the need of dietary supplements (DS) is a complex nutritional issue for society and for individuals. Since consumption of special diets has increased among adolescents, the rational consumption of DS is relevant and interesting learning topic at secondary school.

Araştırmada Genel Kimya III (Analitik Kimya) dersi “Çöktürme Titrasyonları” konusunda örnek-olaya dayalı laboratuvar uygulamalarının öğrencilerin akademik başarılarına etkisinin incelenmesi amaçlanmıştır. Çalışma grubunu bir üniversitenin Fen Bilgisi Öğretmenliği Programında okuyan ikinci sınıf öğrencileri oluşturmaktadır. Mevcut iki şubeden birisi deney (n=32), diğeri kontrol grubu (n=32) olarak rastgele seçilmiştir. Araştırma ön-test son-test kontrol gruplu yarı-deneysel desendir. Deney grubu öğrencileri örnek-olaya dayalı laboratuvar uygulamalarıyla, kontrol grubu öğrencileri ise öğretim programına uygun laboratuvar uygulamalarıyla dersi işlemiştir. Araştırmada çöktürme titrasyonları konusunda günlük yaşamla ilişkili iki örnek olay geliştirilmiştir. İlk örnek olayın konusu, havuz dezenfeksiyonunda aşırı klor gazının kullanımından dolayı zehirlenen bir gence, ikinci örnek olayın konusu ise tatlı su balığının deniz suyuna bırakılması sonucu balığın başına gelenlerin anlatılmasına dayanmaktadır. 11 Açık uçlu sorudan oluşan “Çöktürme Titrasyonları Başarı Testi” veri toplama aracı olarak kullanılmıştır. Testteki açık uçlu sorulara verilen yanıtlar puanlanarak nicel veriler elde edilmiş ve bağımsız ve bağımlı gruplar için t-testi ile analiz edilmiştir. Açık uçlu sorular ayrıca içerik analiziyle analiz edilmiştir. Çalışma sonuçları, örnek-olaya dayalı laboratuvar uygulamalarının öğrencilerin çöktürme titrasyonları (arjantometrik yöntemler) konusunda tam anlamalarını ve akademik başarılarını arttırdığını göstermiştir.
