We present a novel method for demonstrating the physical principles of ultrasound imaging at a level suitable for educational programmes up to the university level, using a simple mechanical model that is very inexpensive and accessible to a broad variety of educational institutions. The method revolves around the use of one or two steel springs…

In this article, I argue that the common practice across many school mathematics curricula of using a variety of different representations of number may diminish the coherence of mathematics for students. Instead, I advocate prioritising a single representation of number (the number line) and applying this repeatedly across diverse content areas.…

Novel games can enrich a physical education (PE) curriculum by providing students opportunities to increase their moderate to vigorous physical activity and understanding new game concepts, playing positions and physical skills (Clancy et al., 2007). Quidditch is a relatively new game that includes unique characteristics to enhance an existing…

In her early work, Suellen Shay argues that higher education tends to valorise objective notions of reality while downplaying the subjectivity of individuals. In Shay's view, this one-sided approach leads to a deficiency in the preparation of students for the holistic reality of the world they will experience beyond university. Taking Shay's…

The field of giftedness legitimates itself on the basis of correlations of gifted-identification measures with future success that do not mean what they often are taken to mean. When one views the inadequacies of these correlations, the field turns out to be much like the emperor who had no clothes. This essay reviews some of the assumptions upon…

Authentic learning in physical education (PE) is one of many tools to promote lifelong movement through meaningful experiences. Self-Determination Theory is tied to authentic learning through student connection in PE and authentic learning. Teachers can become facilitators of authentic learning experiences through embracing a shift in power…

Empathy, being multidimensional in nature, addresses cognitive, social-emotional, and behavioural components of interpersonal interaction. It is considered a core element of global competence. As schools become more diverse, empathy, which expresses the ability to observe social situations from other people's points of view plays a critical…

The goal of the present study was to examine whether college students' learning would be impacted by an innovative teaching strategy--the presentation of Secure Attachment Messaging (SAM) during lecture. Students (N = 205) were presented with SAM every other week as part of the regular PowerPoint slides. At the end of each class, they completed a…

Online teaching became an alternative approach for the teacher to run the teachinglearning activities during the COVID-19 pandemic. In this context, this study aimed to identify the issues of mathematics teachers in teaching mathematics through online mode during the pandemic where issues represented the problems and challenges. Altogether 415…

During the early decades of the 18th century, Newtonian physics was still new. Much effort was expended in testing its validity. One arena in which evidence could be found was the shape of Earth. Was it perfectly spherical? On the observational side there were two hints. In 1671 Jean Richer had measured the rate of ticking of a pendulum clock near…

To a student in introductory physics, using vectors is at best an exercise in bookkeeping. A two-dimensional kinematics problem effectively doubles the number of equations that a student must know, and invites the student to memorize factoids: "The horizontal motion is constant," "Gravity is only in the y-direction," etc. Force…

In mathematics education research, proofs are often conceptualized as sequences of mathematical assertions. We argue that this ignores proofs that contain instructions to perform mathematical actions, often in the form of imperatives, which are common both in mathematical practice and in undergraduate mathematics textbooks. We consider in detail a…

Action research is an evidence-based practice that is highly applicable to middle school teaching and learning. Middle school teachers can empower themselves and their students by participating in immersive, meaningful activities that are designed to improve educational outcomes. Action research is purposeful and beneficial for teachers, students,…

It is well known that students benefit from opportunities to interpret and create different representations (e.g., diagrams, graphs, tables, symbols) of mathematical ideas. Employing Marton's Variation theory as a lens, I argue for an expansion of the use of multiple representations in task design for graphs: Incorporate two different forms of the…

For some time, scholars who are guided by critical theories and perspectives have called out how white supremacist ideologies and systemic racism work to (re)produce societal inequities and educational injustices across science learning contexts in the United States. Given the sociopolitical nature of society, schooling, and science education, it…
