Calculations are presented showing that the usual 'faster than g' demonstration has a surprising property. That is, a rod hinged at its bottom end rotates at an exponentially increasing rate until it falls with maximum vertical acceleration, unlike an object that falls freely by gravity alone. If the rod is hinged at its top end and released from…

There is an ongoing challenge with STEM education: making physics, math, and science, in general, interesting, understandable, and retentive for college science and non-science majors, K-12 students, and the public. If not imparting detailed knowledge, at least one would like to introduce important concepts that will be remembered, appreciated,…

This mixed methods study explored how elementary teachers reported using a commercially published instructional unit to plan and deliver science instruction in their elementary classrooms. Of particular focus is what elements of the program teachers eliminated during planning and instruction, what outside materials teachers added to instruction,…

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…

Developing students' creativity is an important educational goal in many countries. The Australian Curriculum Authority has mandated that all teachers teach creative thinking across all subjects and grades. However, after more than 10 years working within this mandate, how do science teachers see their role in promoting creativity in the…

A variety of methods have been used to analyze the kinetics of various processes related to the Diet Coke and Mentos experiment (also known as the soda geyser). However, none of these previous reports has undertaken a quantitative exploration of the dynamics of the creation and collapse of the soda geyser itself. We have therefore devised a method…

This article introduces and contextualizes the content of this theme issue of "The American Biology Teacher" (ABT), which focuses on integrating elements of the history of science (HOS) in biology instruction. Such orientations can enhance students' understanding of core biological concepts and the process of scientific discovery by…

The longstanding call to prioritize science education has gained momentum, particularly with the noticeable changes aligned with reform-era practices. This quantitative study explored the relationship between policy, time allocation, and teacher practices in elementary science education, guided by constructive learning theory as the theoretical…

Time is a central concept for astronomy, yet how it is communicated in educational contexts has received insufficient attention in the literature. This study explores how time-related concepts are communicated in the planetarium, by analyzing 34 different planetarium sessions held in a diversity of Portuguese institutions. Sessions were video and…

Recently, the physics education community has taken a keen interest in modernising physics education. However, while topics in modern physics have great potential to engage students, these topics are abstract and hard-to-visualise. Therefore, many students hold mistaken pictures and misconceptions, which can impede learning. In this article, we…

We present a tool, one that is both a stand-alone web-based video game and a Python package, designed for students to explore a particle's wave function on one-dimensional potential surfaces. The tool relies on a basis set formalism and can, therefore, explore any one-dimensional potential surface imaginable. This tool also lets students interact…

Regardless of students' differences, they should have opportunities to learn in a classroom environment that adequately promotes their interests and scaffolds their progress. Often, research highlights the struggles teachers face in accommodating learners' needs while ensuring effective lesson delivery at various educational levels. Although there…

In recent years, general relativity (GR) and gravitational-wave astronomy have emerged both as active fields of research and as popular topics in physics classrooms. Teachers can choose from an increasing number of modern instructional models to introduce students to relativistic ideas. However, the true potential of an instructional model can…

This study assessed the efficacy of the spaced learning method compared to the activity-oriented method in improving chemistry achievement among high school students, focusing on different cognitive domains. An experimental design involving pre and post-test control groups was employed, with 106 students from two schools participating. The…

IUPAC nomenclature of lower alkanes (1C to 10C) is quite common and digestible. But students face problems remembering and predict IUPAC word-root during IUPAC nomenclature of higher alkanes (C >11). Here in this innovative article, I have tried to focus IUPAC nomenclature of higher alkanes (11C to 90C) through the prediction of IUPAC word root…
