A magnetic linear accelerator (or Gauss accelerator) is a device that uses the conversion of magnetic energy into kinetic energy to launch an object with high velocity. A simple experimental implementation consists of a line of steel spheres in which the first one is a permanent magnetic sphere. If another steel ball collides with the magnetic…

We designed a multiple baseline study to evaluate an instructional coaching model in which coaches use video recordings of collaborating teachers' classrooms to inform their coaching practices. In this model, teachers and coaches use video evidence to co-construct a student-based goal and identify best practices to reach their goal. We found that…

Students' judgements of their own learning often exceed their knowledge on a given topic. One source of this pervasive overconfidence is fluency, the perceived ease with which information is acquired. Though effects of fluency on metacognitive judgments have been explored by manipulating relatively simple stimuli such as font style, few studies…

How do prosocial sharing behaviours of preschool-aged children progress or diminish when interacting with mobile devices? Participants include five children (ages 3-4) within a preschool setting in Vancouver, British Columbia. Design-based research and video ethnography were used for qualitative and quantitative data collection and analysis. Data…

The prevalence of autism spectrum disorder (ASD) in children has increased dramatically during the last decade. Deficits in social communication and interaction have been identified as recognized impairments for individuals with autism spectrum disorder (ASD). In response to these issues, new behavioral interventions have been developed as…

The presence of Animated Pedagogical Agents (APAs) in education is increasing day-by-day. They are being used in online courses as well as research studies. Therefore, there is a need to study ways in which lectures can quickly be created using APAs. Gestures are an inseparable part of an APA's communication with users. Gestures generated…

The study explored the educational potential of the application of student-generated digital visual content for learning English as a second language (ESL) by undergraduate students enrolled in the course Foreign Language which is actually Introduction to Legal English. This study used a mixed-methods approach. The researchers designed a…

Nobody knows exactly what happened during "the lost years" of the turtles in the wild, thus a green turtle headstarting project was carried out at Pantai Pandan, Lundu, Sarawak, Malaysia from June 2014 until December 2015 to shed some lights on the growth of hatchlings during a small part of their "lost years". As a consequent,…

Video-based instruction (VBI) has a substantial amount of research supporting its use with individuals with autism spectrum disorder and other developmental disabilities. However, it has typically been implemented as a treatment package containing multiple interventions. Additionally, there are procedural variations of VBI. Thus, it is difficult…

Videos of classroom lectures have proven to be a popular and versatile learning resource. A key shortcoming of the lecture video format is accessing the content of interest hidden in a video. This work meets this challenge with an advanced video framework featuring topical indexing, search, and captioning (ICS videos). Standard optical character…

In this article, we report on "Researching Mathematics Leader Learning" ("RMLL"), a project designed to support leaders in learning how to facilitate robust opportunities for teachers' mathematical learning. Our two-phase research design allowed us to construct a set of videocase seminars, enact the seminar design with leaders,…

Slow motion video enhances our ability to perceive and experience the physical world. This can help students and teachers especially in cases of fast moving objects or detailed events that happen too quickly for the eye to follow. As often as possible, demonstrations should be performed by the students themselves and luckily many of them will…

In this paper we report an investigative activity on hydrodynamics, in the context of an inquiry-based learning project. The aim is to analyse the experiment of a bullet shot underwater. Using "Tracker," a video analysing and modelling software, the displacement of the bullet was measured as function of time, processing a slow motion…

The paper reports on the use of culturally relevant teaching in a class located in a patriarchal community. The paper is conceptualised around the notion that learners' familiar context provided by the socio-cultural activities can facilitate mathematics learning and make it fun to learn. Data were derived from a lesson activity using…

Videos are often used for demonstration and evaluation, but a more productive approach would be using video to support teachers' ability to notice and interpret classroom interactions. That requires thinking carefully about the physical aspects of shooting video--where the camera is placed and how easily student interactions can be heard--as well…
