We describe the design and implementation of a teaching-learning sequence that was started before the lockdown and was then transformed for distance teaching. A backward design approach was adopted in order to identify clear learning outcomes. The activities were outlined according to an inquiry-based learning paradigm, referring to research-based…

General chemistry, CHE 101, at Hampton University is an undergraduate course designed to meet curriculum requirements for nonscience majors. The four-credit course consists of a lecture and a laboratory, taken concurrently. The lecture consists of three 50 minute or two 75 minute sessions, and the laboratory consists of one 3 hour session every…

The private company SpaceX regularly launches satellites into geostationary orbits. SpaceX posts videos of these flights with telemetry data displaying the time from launch, altitude, and rocket speed in real time. In this paper this telemetry information is used to determine the velocity boost of the rocket as it leaves its circular parking orbit…

Students struggle with observing scientifically and connecting observations to scientific theory. This study investigates how students actually use observation in rock classification -- a classical practical task in science education. To describe the level of students' use of observation, data was collected by videotaping 19 small student groups…

This research aims to develop a falling chain experiment apparatus using kitchen scales and digital cameras (smartphones). Digital cameras were used to observe and record changes in the mass of falling chains measured using kitchen scales. Video recordings from observations of falling chain masses were analysed using Tracker 5.1.1 software. The…

A wood cantilever of length ~2.5 m is driven into resonance using the hand as a simple driver. Video recordings of these oscillations are analyzed to determine experimental second harmonic (n = 2) damped resonance frequencies. These frequencies are compared to theoretical ones, obtained from measurements of elastic moduli, damping properties, and…

In 2019 and 2020, third-year chemical engineering majors completed a concept inventory at the beginning and end of the semester in their thermodynamics course. Midway through spring semester of 2020, the course switched to emergency remote instruction, replacing hands-on inquiry-based laboratory activities (IBLAs) with short videos. Analysis of…

Supporting students in building well-grounded explanations plays a crucial role in scientific practice. Research in organic chemistry education on students' mechanistic explanations, however, has revealed various challenges. When solving mechanistic tasks, students experience difficulties when (I) deriving implicit properties from structural…

Online videos are an increasingly important way technology is contributing to the improvement of physics teaching. Students and teachers have begun to rely on online videos to provide them with content knowledge and instructional strategies. Online audiences are expecting greater production value, and departments are sometimes requesting educators…

Teachers' responses to student contributions in science classroom influence the resulting classroom interaction. To establish a heightened interaction, teachers need to use specific discursive moves. Using the notion of noticing as a lens, in this qualitative case study, I report on how the notion of noticing and responding with a suitable…

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,…

The damped harmonic oscillator physics problem is a standard oscillation problem in calculus physics for pre-engineering students in a community college. The use of alternative linear algebra eigenvalue stability method is consistent with the upper engineering courses using control theory. The external force and friction damping would become the…

Use of flipped learning environments, where content is delivered online outside of class and class time features student-centered activities, is an increasingly popular way to facilitate active learning. The success of classroom activities, however, depends on students' willingness to complete the out-of-class work and come to class well prepared.…

A video is taken of a road-sign mirage from the passenger seat in a car traveling at constant speed on a highway. The video spans the duration of seeing the mirage of the sign, viewing the vanishing of the mirage as the car approaches, and passing the road sign. The mirage angle, defined as the angle with respect to the horizontal at the moment…

Students are amazed when I show them a zoo photo of an animal behind a fence and then a zoomed-in photo where the fence has disappeared. They ask 'Where did the fence go?' This paper will explore this magical phenomenon which draws from concepts in photography (angle of view, depth of field) and physics (convex lenses, focal length, real images).…
