The traditional approach to using videos involves the so-called "movie sandwich," which focuses on the use of a single video clip. Based on analogical learning research, we highlight the possible benefits of constructing what we term a "video bridge," which consists of two analogous videos that are linked by important themes of…

Cyberbullying is the use of digital communication tools and spaces to inflict physical, mental, or emotional distress. This serious form of aggression is frequently targeted at, but not limited to, vulnerable populations. A common problem when creating machine learning models to identify cyberbullying is the availability of accurately annotated,…

In this article, we describe the purpose and the process of video-cued ethnography. Using examples primarily from the Children Crossing Borders study, we outline six basic elements of video-cued ethnography including site selection, participant-observation, filming, editing, focus group interviews, and comparative analysis. We detail some of the…

In this work we describe a teaching proposal to calculate the eccentricity of the Moon's trajectory by applying a geometrical technique. The values of the ratios between the Earth-Moon distance and the diameter of the Moon at apogee and at perigee were calculated from a kinematic model associated with a geometrical technique of image analysis. The…

People re-identification has been a very active research topic recently in computer vision. It is an important application in surveillance system with disjoint cameras. This paper is focused on the implementation of a human re-identification system. First the face of detected people is divided into three parts and some soft-biometric traits are…

Massive online Open Courses (MOOCs) make extensive use of videos. Students interact with them by pausing, seeking forward or backward, replaying segments, etc. We can reasonably assume that students have different patterns of video interactions, but it remains hard to compare student video interactions. Some methods were developed, such as Markov…

Consider a chain of length L that hangs in a U shape with end A fixed to a rigid support and free end E released from rest starting from the same initial height (call it y = 0) as A. Figure 1 sketches the chain after end E has fallen a distance y. Points O and A are assumed to be close enough to each other and the chain flexible enough that the…

In 1982 I began using classroom videos as cues for ethnographic interviews. My colleagues and I asked practitioners in three countries to respond to videos shot in their own and each other's preschools. The video cues worked to produce conversations that we used in our 1989 book "Preschool in Three Cultures" to present perspectives on…

Flipped instruction is being implemented in an increasing number of mathematics classes but the research base is not yet well developed. Many studies of flipped instruction involve a small number of flipped classes being compared to non-flipped classes, but this methodology fails to account for variations in implementations. To aid in the…

The design of balanced assembly lines, especially when considering workforce, material, and cycle time factors, is an important managerial decision-making activity in manufacturing firms. Numerous active learning activities are available to assist instructors in teaching assembly line balancing to students. While effective in improving student…

With the rise of so-called fake news as a global phenomenon, interest in propaganda analysis has advanced along with the recognition of the fundamentally social process of interpretation. In this essay, we explore the use of cross-national dialogue among German and American undergraduate students who are seeking to better understand how media…

Much is known about the benefits of interacting with animals for learners. However, little is known about the animals' potential influence on the communication ability of the presenter/educator. The purpose of this qualitative study was to describe the experience of undergraduate students who used live animals (baby chicks, turtles, salamanders,…

In this paper, we describe how simple experiments realizable by using easily found and low-cost materials allow students to explore quantitatively the magnetic interaction thanks to the help of an Open Source Physics tool, the Tracker Video Analysis software. The static equilibrium of a "column" of permanents magnets is carefully investigated by…

We report a simple experiment that clearly demonstrates a common error in the explanation of the classic experiment where a small piece of paper is put over a book and the system is let fall. This classic demonstration is used in introductory physics courses to show that after eliminating the friction force with the air, the piece of paper falls…

The cognitive interview (CI) is one of the most widely accepted forms of interviewing techniques for eliciting the most detailed, yet accurate reports from witnesses. No research, however, has examined its effectiveness with witnesses with autism spectrum disorder (ASD). Twenty-six adults with ASD and 26 matched typical adults viewed a video of an…
