This qualitative multiple case study comprised an investigation of the beliefs, understandings, and experiences of school principals charged with overseeing the curricular innovations and implementations taking place at four STEM elementary schools. The study was organized around a proposition based on five factors adopted from the "Framework…

Harmful plastic debris found on beaches and in the oceans are not limited to drinking straws or bags. There are several synthetic organic polymers that can be used to make different kinds of plastic materials and have resulted in billions of tons of waste that can reach the aquatic biome and are harmful to freshwater and marine communities as well…

In this article, we describe how to develop an inductive metal detector that can be integrated to any Android or iOS smartphone with a standard audio port at low cost. The results indicate the metal detector can be used in the physics teaching laboratory as a practical application of principles of electromagnetism. It allows one to differentiate…

This study demonstrated that the constant average speed of a dynamic car could be measured and calculated using the smartphone magnetometer. The apparatus setup was built using a dynamic car, a linear track up to 1.50 m, a bunch of magnets, and a smartphone magnetometer application. The smartphone magnetometer application, 'Physics Toolbox Suite',…

Crosscutting concepts like patterns and models are fundamental parts in both the American framework of science education (from the AAAS) and our proposals for a new science education framework in Flanders. These concepts deepen the insight of both students and teachers. They help students to ask relevant questions during an inquiry and they give…

Magnetism and its various applications are essential for our daily life and for many technological developments. The term "magnetism" is almost always used as a synonym for ferromagnetism. However, the magnetic properties of the elements of the periodic table indicate that the vast majority of elements are not ferromagnetic, but rather,…

The new 9-1 GCSE courses in Physics include reference to both permanent and induced magnets. In this article I briefly examine the origin of ferromagnetism, diamagnetism and paramagnetism and suggest a number of helpful classroom demonstrations.

Recent GCSE and IGCSE specifications include reference to both permanent and induced magnetism, giving the opportunity for novel classroom demonstrations based on ferromagnetism and paramagnetism, and the transition between these phases. Ferromagnetic materials lose their magnetism if raised above their Curie Temperature, a specific temperature…

How do magnet schools work? Although they are an important school-choice option (on par with charters, in terms of enrollment), it is unclear what actually goes on in these schools: how do they reduce minority-group isolation? What does theme-based teaching and learning look like in practice? This report answers these questions with findings from…

Science lessons in nature are appealing and potentially supportive of children's learning, but little is known about how and for whom they are effective. A within-subjects, experimental, mixed methods design was employed with 92 4th-graders to determine if, why and for whom science learning is better through outdoor, nature-based instruction (NBI)…

We have developed a laboratory exercise designed to help students translate between different field representations. It starts with students qualitatively mapping field lines for various bar magnet configurations and continues with a Hall probe experiment in which students execute a series of scaffolded tasks, culminating in the prediction and…

In this paper we discuss the role of transduction in the teaching and learning of science. We video-filmed pairs of upper-secondary physics students working with a laboratory task designed to encourage transduction (Bezemer & Kress, 2008). The students were simply instructed to use a hand-held electronic measurement device (IOLab) to find the…

Systems thinking is highly desirable for re-imagining chemistry education, which will help in the development of an integrated and sustainable approach that takes into account the interdependence of a system under study with other components of the ecosystem rather than practicing a fragmented approach. Thus, to develop a systems' perspective into…

Concept inventories (CIs) are commonly used in pre-post instruction to study student conceptual change. For consistency in assessment interpretation, a CI's assessment construct is desired to maintain invariance across different test times. In this study, the longitudinal measurement invariance (LMI) analysis under the confirmatory factor analysis…

The purpose of this study was to examine the impact of the social and cultural instructional process on independent reading. In addition, the purpose of this study was to examine the effect of the administrator-teacher relationship on educational practices in a lab site classroom. Using an action research design, data was collected through…
