This study examined how using two different ways of displaying the solar system--a true-to-scale mode vs. an orrery mode--affected students' knowledge of astronomical concepts. Solar system displays were presented in a software application on a handheld tablet computer. In the true-to-scale mode, users navigated a simulated three-dimensional…

Traditional science instruction is typically reliant on visual modes of learning, such as textbooks and graphs. Furthermore, since science instruction is often heavily dependent upon visual cues, students with visual impairment often do not have access to the same educational opportunities in most science classes (Jones, Minogue, Oppewal, Cook,…

This paper explores whether facial microexpression state (FMES) changes can be used to identify moments of conceptual conflict, one of the pathways to conceptual change. It is known that when the preconditions of conceptual conflicts are met and conceptual conflicts are detected in students, it is then possible for conceptual change to take place.…

The Next Generation Science Standards and other reforms call for students to learn science-as-practice, which I argue requires students to become epistemic agents--shaping the knowledge and practice of a science community. I examined a framework for teaching--ambitious instruction--that scaffolds students' learning of science-as-practice as…

An overlooked feature in astronomy education is the need for students to learn to extrapolate three-dimensionality and the challenges that this may involve. Discerning critical features in the night sky that are embedded in dimensionality is a long-term learning process. Several articles have addressed the usefulness of three-dimensional (3D)…

This paper is concerned with the conceptualization of pedagogical content knowledge (PCK) for teaching about the nature of science. In contrast to the view that science teachers need to develop a specific "PCK for nature of science," an alternative, more comprehensive notion of PCK for science teaching is suggested. The point of…

Within the increasing body of research that examines students' reasoning on socioscientific issues, we consider in particular student reasoning concerning acute, open-ended questions that bring out the complexities and uncertainties embedded in ill-structured problems. In this paper, we propose a socioscientific sustainability reasoning…

Research has now demonstrated that students can learn nature of science concepts variously through student-led investigations, contemporary cases, and historical cases. Here we articulate more precisely the merits, deficits, and context of each approach and begin to profile how to integrate them as complementary methods. Emphasis now needs to…

This article presents the design of an immersive simulation and inquiry activity for technology-enhanced classrooms. Using a co-design method, researchers worked with a high school biology teacher to create a rainforest simulation, distributed across several large displays in the room to immerse students in the environment. The authors created and…

Given the centrality of evolutionary theory to the study of biology, we present a strategy for reinforcing its importance by appropriately recontextualizing classic and well-known experiments that are not explicitly linked with evolution in conventional texts. This exercise gives students an appreciation of the applicability of the theory of…

Scientific experiments are indispensable parts of Biochemistry and Molecular Biology. In this study, a comprehensive Biochemistry and Molecular Biology experiment about "Salmonella enterica" serovar Typhi Flagellar phase variation has been designed. It consisted of three parts, namely, inducement of bacterial Flagellar phase variation,…

Biochemistry is a visual discipline that requires students to develop an understanding of numerous representations. However, there is very little known about what students actually understand about the representations that are used to communicate ideas in biochemistry. This study investigated biochemistry students' understanding of multiple…

Previous research has shown that the Swedish preschool educational tradition is characterised by outdoor-oriented and democratic approaches. The purpose of this study is to empirically investigate what consequences these approaches have for preschool children's meaning-making of nature, when studied in practice, in children's spontaneous…

We present a lab that enables students to test the role of genes involved in the regulation of lateral roots growth in the model plant "Arabidopsis thaliana." Here, students design an experiment that follows the effects of the hormone auxin on the stimulation of genes involved in the formation of lateral root initials. These genes, known…

The purpose of the present study was to explore how often teachers of young children teach science concepts in kindergarten and examine the factors that influence the frequency of science teaching in early years. A theoretical model of the determinants of the frequency of science teaching in kindergarten was developed and tested using a…
