Research in science education agrees that one of the key challenges of learners in the discipline is certainly connecting domain-specific representations to the underlying concepts. One way of supporting students to make applicable connections is using purposefully designed highlighting techniques in multimedia instructions. In order to examine…

Whilst video has become a central reflective tool in teacher education and teacher professional development, video-based collaborative reflection is just starting to gain traction as a research approach. The authors develop their understanding of this approach by examining how teacher noticing can be extended in teacher reflection. Specifically,…

The percentage of college students receiving unproductive grades in introductory mathematics courses is a concern for post-secondary institutions across the country. Many factors can be targeted as potential explanations for this lack of success, yet none of these issues are more noteworthy than the fact that many students enter college…

Generalization is a critical component of mathematics learning, but it can be challenging to foster generalization in classroom settings. Teachers need access to better tools and resources to teach for generalization, including an understanding of what tasks and pedagogical moves are most effective. This study identifies the types of instruction,…

For this study, 11 children with moderate to severe autism spectrum disorder (ASD) were given directives containing prepositions in three cue conditions: (a) spoken alone, (b) a short video clip along with spoken cues, and (c) a sequence of three graphic symbols accompanied by spoken cues. Participants followed directives significantly more…

The need to improve the mathematical proficiency of elementary teachers is well recognized, and it has long been of interest to educators and researchers in the U.S. and many other countries. But the specific proficiencies that elementary teachers need and the process of developing and improving them remain only partially conceptualized and not…

Streaming is an emerging practice of videogame culture, where a player broadcasts a live capture of their game-play to an audience. Every day Twitch.tv, the most popular streaming platform, features thousands of streams broadcast to millions of viewers. Streams are detailed multimedia artifacts, and their study allows us to understand how the…

Production frequency has often been used to identify central and peripheral information, under the assumption that high frequency implies that the item is central. However, no research to date has tested the relationship between centrality and frequency. Participants watched a video of a bank robbery and completed a free recall test, from which…

Little is known about how observers' scanning strategies affect performance when monitoring events in closed-circuit television (CCTV) footage. We examined the fixation behaviour of change detectors and non-detectors monitoring dynamic scenes. One hundred forty-seven participants observed mock CCTV videos featuring either a mock crime or no crime.…

I advance theoretically and empirically grounded arguments for broadening how we frame and understand situational interests. A situational interest refers to the short-term spike in a person's attention and participation in an activity and it is triggered in the interactions between the person and environment features (e.g., novelty and surprise).…

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.

Past research suggests that speakers gesture more when motor simulations are more strongly activated. We investigate whether simulations of a perceptual nature also influence gesture production. Participants viewed animations of a spider moving with a manner of motion that was either highly salient (n = 29) or less salient (n = 31) and then…

Purpose: We examined receptive verb knowledge in 22- to 24-month-old toddlers with a dynamic video eye-tracking test. The primary goal of the study was to examine the utility of eye-gaze measures that are commonly used to study noun knowledge for studying verb knowledge. Method: Forty typically developing toddlers participated. They viewed 2…

Nowadays, in almost any country in the world, it is difficult to find a young person who has never played with, seen, or heard of the most famous toy in 2017: the fidget spinner. According to Wikipedia: "The fidget spinner is a toy that consists of a ball-bearing in the center of a multi-lobed flat structure made from metal or plastic…
