Various experiments and demonstrations relate air pressure and air pressure difference to force and area. Carpenter and Minnix describe a large-scale pneumatic lift in which a person sitting on a board atop a plastic garbage bag is lifted when the bag is connected to the exhaustport of a vacuum cleaner, which easily lifts the person. This article…

Evolution has been positioned at the centre of conflict between scientific and religious explanations of the workings of the world. However, little research has examined other possible reasons for some people rejecting scientific explanations. The author's research indicates that for some people, irrespective of faith, the ideas associated with…

Physics education research has a tradition of studying problem solving, exploring themes such as physical intuition and differences between expert and novice problem solvers. However, most of this work has focused on traditional, or well-structured, problems, similar to what might appear in a textbook. Less work has been done with open-ended, or…

Plants and the outdoors may be something of a mystery to a generation of children who are reportedly spending more and more time indoors; this has the potential to inhibit real understanding of many complex biological processes. Taking children outdoors introduces them to a world from which they are becoming increasingly distant. However, a…

Iron metabolism is an important subject of study for undergraduate students of chemistry and biochemistry. Relevant laboratory exercises are scarce in the literature but would be very helpful in assisting students grasp key concepts. The experiment described here deals with different iron release mechanisms of two protagonists in iron metabolism:…

This article presents recent research results in mental chronometry and neuroimaging that support the coexistence of multiple conceptions. It then presents and elaborates on six possible implications for an adherence to the coexistence claim within the context of scientific conceptual learning: (1) stop the war on misconceptions; (2) use a…

Adding an evolutionary perspective to anatomy teaching can enrich student learning. One way of introducing evolutionary concepts into a course is by "sneaking it in" by presenting interesting and sometimes entertaining "stories" that add anatomical detail, encourage critical thinking, and illustrate underlying evolutionary…

Chemish - the scientific language of chemistry - is crucial for learning chemistry. To help students acquire the competencies to understand and use Chemish, chemistry teachers need to have a sound knowledge of teaching and learning Chemish: Pedagogical Scientific Language Knowledge (PSLK). But still, despite the importance of this knowledge, the…

Background: Although the reading of science texts has been reported for high school learners, there is not much research on how younger learners engage with expository texts and how they develop academic language skills. In the instance of this study, the topic came from the curriculum content about animal reproduction. Aim: The study from which…

Following a theoretical framework that recognizes the potential of promotive and inhibitive effects on children's development, this study explored child-, family-, classroom-, and school-level factors as predictors of Latinx (N = 4,590) students' early elementary science achievement. Research Findings: Employing a path modeling approach with…

This article examines two teachers' efforts to re-organize their science teaching around issues of environmental and food justice in the urban community where they teach through the pedagogical approach of community-oriented framing. We introduce this approach to teachers' framing of phenomena in community as supporting students' framing of…

This successful guide--now in a revised and expanded second edition--gives teachers effective strategies to support adolescents' development of relevant literacy skills in specific disciplines. Demonstrating why disciplinary literacies matter, the authors discuss ways to teach close reading of complex texts; discipline-specific argumentation,…

Although teachers' instruction has been extensively studied, there is a dearth of research investigating how teachers design lessons and integrate new information into their existing lessons. This study utilized a case study approach to examine how teachers engaged in a nanoscale science professional development experience integrated new science…

This study investigated (i) the effect of inquiry-oriented laboratory activities on preservice primary school teachers' (PPSTs) achievement in science process skills (SPS) and science teaching efficacy beliefs, and (ii) changes in groups' reflections of SPS in the laboratory reports as they engaged in the activities. There were 71 PPSTs enrolled…

The purpose of this study was to examine the effects of a technology-based self-monitoring application, I-Connect, to enhance the on-task behavior of five secondary students (ages 15-16) with autism spectrum disorder, intellectual disability, and specific learning disability during Biology instruction in a rural special education classroom. We…
