Aspects of preschoolers' ecological understandings were explored in a cross-age, quantitative study that utilised a sample of seventy-five 3- to 5-year-old children. Specifically, their concepts of feeding relationships were determined by presenting physical models of three-step food chains during structured interviews. A majority of children,…

Previous research has documented that students who engage with socioscientific issues can acquire some of the complex competences and skills typically related to scientific literacy. But an emerging field of research on science teachers' understanding and use of socioscientific issues, has documented that a range of challenges hinders the uptake…

Science education today has become increasingly focused on research into complex natural, social and technological systems. In this study, we examined the development of high-school biology students' systems understanding of the human body, in a three-year longitudinal study. The development of the students' system understanding was evaluated…

STEM, an acronym for Science, Technology, Engineering and Mathematics, is widely used in science education. There is confusion, however, as to its provenance and meaning which is potentially problematic. This study examines the purpose of STEM practice in education in England and asks if there are differences in perceptions of STEM between science…

When conducting scientific research, experts in molecular and cellular biology (MCB) use specific reasoning strategies to construct mechanistic explanations for the underlying causal features of molecular phenomena. We explored how undergraduate students applied this scientific practice in MCB. Drawing from studies of explanation building among…

Science standards in the U.S. have shifted to emphasise science and engineering process skills (i.e. specific practices within inquiry) to a greater extent than previous standards' emphases on broad representations of inquiry. This study examined the alignment between second-career science teachers' personal histories with the latter and examined…
