Physics textbook authors commonly introduce the concept of weightlessness (apparent or real) through a "thought experiment" in which a person weighs herself or himself in an elevator. When the elevator falls freely, the spring balance should show zero weight. There is an unresolved controversy about how this "zero reading"…

This paper describes a cost effective and safe device to perform realistic experiments on the physics of radioactivity in classrooms. It can be used to study both a- and ß-radioactivity as well as ?-emitters and shows extremely realistic behaviour. The device, in the form of a Geiger--Müller tube, was tested during a public lecture and it deceived…

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.…

The authors describe a method for integrating video into the work of elementary literacy coaches. Drawing on their research in developing an online application of a successful literacy-coaching program called Content-Focused Coaching, the authors describe an approach that coaches can use to reflect with teachers on their video recorded lessons to…

Background: This article is about interactions that occur when someone with intellectual disabilities is engaged in everyday activities with a personal assistant (PA) or a support worker. Method: We examine the detail of nine hours of naturally occurring video-recorded interactions, to explore how "relational autonomy" is done in…

This article reports on our use of a "deaf lens" in adapting video-cued multivocal ethnography for the "Deaf Kindergartens in Three Countries: Japan, France, and the United States" project. Beginning with a discussion of how this "deaf lens" shaped the design of the study, research questions, and methodology, the…

Educational videos are becoming more prevalent within a higher education context and the use of videos is now taken for granted. However, the full impact videos have on learning is under researched and not fully known. This study was conducted to investigate the effectiveness of quiz questions embedded throughout a video. Students from different…

As the use of videos for learning increases, the need to better use the viewing experience also increases. EDpuzzle is a video-sharing program that offers instructors a way to enhance the use of online videos for learning. It allows instructors to ensure that students have viewed the lesson in its entirety and determine whether they understood its…

In this article, we revisit fragments of data from a three-year study, paying close attention to the entanglements and inseparability of child/plastic/snow/GoPro within children's everyday encounters and narratives in an immersive nature-based program in Canada. We query how these entangled ways of being might help inform environmental and…

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…

This article deals with the problem of increasing the efficiency in motor learning with the help of video analysis. The text approaches the system providing a feedback in the process of downhill skiing skills acquisition. The platform influencing the movement notion introduces innovative means of the acquisition of essential downhill skiing skills…

David Hibbert and Zaiba Patel decided to work together after becoming concerned that school history curricula might not enable students to interrogate popular British mythologising about World War II. Building on these pre-existing concerns, their collaboration with the historian Yasmin Khan yielded an Interpretations enquiry which asked students…

Schools can use School-Wide Positive Behavior Interventions and Supports (SWPBIS) videos as a tool for teaching school-wide expectations and other targeted skills. Although some schools integrate SWPBIS videos into their universal framework, little is known about the creation and implementation of these videos. Through an online survey,…

We conducted a meta-analysis of the single-case research design data on the effects of video prompting (VP) on the acquisition of daily living skills (DLS) among individuals with autism spectrum disorder (ASD). An analysis of potential moderators was conducted, and these included VP implemented alone versus VP with additional response prompting or…

Video self-modeling (VSM) has been an effective intervention for individuals with a variety of disabilities and behavioral issues. However, no studies have addressed the impact of VSM on behaviors that are displayed by groups of students. The purpose of the present study was to determine the efficacy of VSM to improve the speed with which students…
