The purpose of this study is to investigate the effect of explicit-reflective nature of science (NOS) instruction on Turkish prospective chemistry teachers' (PCTs) views of NOS. In the research, case study as a qualitative design was used and PCTs' views were examined thoroughly. The participants of the study consisted of 22 senior PCTs. Data…

The purpose of this work is to reconsider and critically discuss the conceptual foundations of modern biology and bio-sciences in general, and provide an epistemological guideline to help framing the teaching of these disciplines and enhancing the quality of their presentation in High School, Master and Ph.D. courses. After discussing the…

Sense-making has been described as working on and with ideas--both students' ideas and authoritative ideas in texts--to build coherent storylines, models, and/or explanations. This article describes the process for developing storyline units to support students' making sense of and explaining a rocket launch. The storyline approach, which aligns…

To develop scientific literacy, elementary students should engage in knowledge building of core concepts through scientific practice (Duschl, Schweingruber, & Schouse, 2007). A core scientific practice is engagement in scientific modeling to build conceptual understanding about discipline-specific concepts. Yet scientific modeling remains…

Molecular model kits have been used in chemistry classrooms for decades but have seen very little recent innovation. Using 3D printing, three sets of physical models were created for a first semester, introductory chemistry course. Students manipulated these interactive models during class activities as a supplement to existing teaching tools for…

Attribution theory deals with the question of how individuals make judgments and seek to explain how they consider the causes of their behaviours and those of others. Attributions have the potential to affect beliefs, emotions and behaviour. Therefore, attribution theory has significantly contributed to the studies on motivation. This study…

This study examines the effectiveness of a teaching-learning sequence (TLS) to improve the understanding of the influences and interactions between a technology (mining) and society. The aim of the study is also to show the possibility of both teaching and assessing the most innovative issues and aspects of scientific competence and their impact…

For over a century and a quarter, the science of learning has expanded at an increasing rate and has achieved the status of a mature science. It has developed powerful methodologies and applications. The rise of this science has been so swift that other learning texts often overlook the fact that, like other mature sciences, the science of…

Richard Feynman, the celebrated physicist, is frequently attributed as saying that "philosophy of science is about as useful to scientists as ornithology is to birds. " Professor Feynman taught at the California Institute of Technology for many years, but perhaps this experience did not afford him the best view of the general level…

This study aimed to determine the changes in understanding about the nature of science (NOS) and conceptual values of 28 elementary science teacher candidates who engaged in the instruction of the nature and history of science (NHOS). A values scale was used to determine the values of science teacher candidates in six areas of the conceptual…

The research reported here investigated the everyday and scientific repertoires of children involved in semi-structured, Piagetian interviews carried out to check their understanding of dynamic astronomical concepts like daytime and night-time. It focused on the switching taking place between embedded and disembedded thinking; on the imagery which…

Recent calls to action urge sweeping reform in science education, advocating for improved learning for "all" students--including those majoring in fields beyond the sciences. However, little work has been done to characterize the differences--if any exist--between students planning a career in science and those studying other…

In this work, we present a teaching-learning sequence on colour intended to a pre-service elementary teacher programme informed by History and Philosophy of Science. Working in a socio-constructivist framework, we made an excursion on the history of colour. Our excursion through history of colour, as well as the reported misconception on colour…

This article focuses on the dilemmas science educators face when having to introduce Pedagogical Content Knowledge (PCK) to science student teachers in a predominantly paper-based distance learning environment. It draws on the premise that science education is bound by the Nature of Science (NOS), and by the Nature of Scientific Inquiry (NOSI).…

Do social cognition and epistemological understanding promote elementary school children's experimentation skills? To investigate this question, 402 children (ages 8, 9, and 10) in 2nd, 3rd, and 4th grades were assessed for their experimentation skills, social cognition (advanced theory of mind [AToM]), epistemological understanding (understanding…
