Oblique angle collisions of two penny coins on a smooth, horizontal surface were filmed with a video camera to investigate the physics of the collision process. If one of the coins is initially at rest, then the two coins emerge approximately at right angles, as commonly observed in billiard ball collisions and in puck collisions on an air table.…

Qualitative studies in the domain of physics education research have become more common in the last several decades. Methodologically, this has been marked by an expansion of the types of data collected in physics education research (PER): namely, in the use of individual and group interviews, problem-solving sessions, and classroom…

Granular flows appear frequently in the natural world and in civil engineering applications. These flows can exhibit features which are surprising and counter-intuitive and are often used to test the limits of the classical continuum approximation for modelling of fluid flows. An important sub-class of the granular flows are the gravity-driven…

The study of buoyancy is common in physics classrooms. In the last 20 years, several educators have described, theoretically and experimentally, buoyant forces and Archimedes' principle, both in "The Physics Teacher" and elsewhere. However, as far as I know, no one has reported on the pedagogical implications and experimental results of…

For science students doing traditional laboratory experiments, often it may feel as if the apparatus and experiment have been specifically chosen for good results. They suspect that the science they are learning in the classroom will not match nearly as well in the real world. However, many educators have observed that student motivation and…

This article describes the educational and public engagement outcomes of an activity called the "ChemClout Challenge" that was implemented in a general chemistry course at UC Riverside. Students worked in groups to make chemistry-themed videos, posted them to social media platforms, then voted on their favorite videos. The majority of…

A virtual catalytic reactor laboratory (VCRL) experiment, which can be used in most browsers, is described. Students select feed conditions and use the VCRL to take data for a gas-phase catalytic reaction and fit kinetic parameters to a Langmuir-Hinshelwood rate expression. The VCRL contains instructions, equipment descriptions, an animated…

This paper presents the creation of an educational resource using the camera of a mobile phone and video analysis software. The movie recorded is part of a daily context: an airplane's take-off. This work shows a way to introduce information and communication technologies (ICT) and digital educational resources (DER) as tools to teach and…

When measuring the speed of an object with a video camera, a correction may be needed for the time taken by the camera to acquire the image in each frame. Examples are given where the correction is quite significant.

The COVID-19 pandemic necessitated the move to online teaching and assessment. This has created challenges in teaching laboratory skills and producing assessments that are robust and fair. Our solution was to use bespoke laboratory videos to provide laboratory training and to generate unique data sets for each student in coursework and exams. For…

Student-generated videos are growing in popularity in education generally, and in chemistry education there are several reports emerging on their use in practice. Interest in their use in chemistry is grounded in the visual nature of chemistry, the role of laboratory work in chemistry, and a desire to enhance digital literacy skills. In this…

Increasingly, learning in science and mathematics is considered in terms of induction into the multimodal language practices of the disciplinary community. A strong strand of research in this tradition has involved students being challenged to invent multimodal language forms, and their ideas refined through structured guidance. Often, however,…

The widespread transition to online teaching as a result of the global pandemic moved chemistry laboratory experiences online. At UBC's Okanagan campus, organic chemistry laboratory instruction was delivered synchronously to maximize student interactions with their teaching assistants. Two methods of online delivery were employed: (1) students…

Chemical reactions far from equilibrium can exhibit oscillatory behavior. Full understanding of this phenomenon is outside of the school curriculum. However, the importance of such processes in life sciences and peculiar spatial and temporal patterns accompanying the reactions can attract the attention of IB Diploma science students. They will…

Flipped classrooms provide students the opportunity to collaboratively solve challenging problems in class with help and scaffolding available from instructors. Because there are many ways to structure a flipped course, research on the effectiveness of flipping classrooms has produced mixed results. Therefore, it is important for researchers to…
