Two experiments demonstrate that 5-month-olds are sensitive to local redundancy in visual-temporal sequences. In Experiment 1, 20 infants saw 2 separate sequences of looming colored shapes that possessed the same elements but contrasting transitional probabilities. One sequence was random whereas the other was based on bigrams. Without any prior…

Video analysis of 2-D collisions is an excellent way to investigate conservation of linear momentum. The often-desired experimental design goal is to minimize the momentum loss in order to demonstrate the conservation law. An air table with colliding pucks is an ideal medium for this experiment, but such equipment is beyond the budget of many…

This article explains how interpreters for deaf-blind people coordinate and express turn-taking signals in an interpreted dialogue. Empirical materials are derived from a video-ethnographic study of an interpreted-mediated board meeting with five deaf-blind participants. The results show that the interpreters provide access to visual and auditory…

Learning algebra is critical for students in the U.S. today. Algebra concepts provide the foundation for much advanced mathematical content. In addition, algebra serves as a gatekeeper to opportunities such as admission to college. Yet many students in the U.S. struggle in algebra classes. Researchers claim that one reason for these difficulties…

Reliability estimations of workplace-based assessments with the mini-CEX are typically based on real-life data. Estimations are based on the assumption of local independence: the object of the measurement should not be influenced by the measurement itself and samples should be completely independent. This is difficult to achieve. Furthermore, the…

In this article, the author allows Robert B. Davis to state for himself his own Principles concerning how children learn, and how teachers can best teach them. These principles are put forward in Davis' own words along with detailed documentation. The author goes on compare Davis' words with his practices. A single Davis video (Towers of Hanoi) is…

YouTube users have access to the powerful data collection tool, Insight. Insight allows YouTube content producers to collect data about the number of online views, geographic location of viewers by country, the demographics of the viewers, how a video was discovered, and the attention span of the viewer while watching the video. This article…

Because simulators offer the possibility of functioning as authentic representations of real-world tasks, these tools are regarded as efficient for developing expertise. The users' experience of realism is recognised as crucial, and is often regarded as an effect of the similarity between reality and the simulator itself. In this study, it is…

Comprehending spoken words requires a lexicon of sound patterns and knowledge of their referents in the world. Tincoff and Jusczyk (1999) demonstrated that 6-month-olds link the sound patterns "Mommy" and "Daddy" to video images of their parents, but not to other adults. This finding suggests that comprehension emerges at this young age and might…

At the Computers and Writing 2011 Conference in Ann Arbor, Michigan, Gail E. Hawisher was celebrated for her many contributions to the field. At that conference, Hawisher gave a keynote address entitled "Our Work in the Profession: The Here and Now of the Future." This video publication includes contributions from scholars who wanted to share…

In the typical public speaking course, instructors or assistants videotape or digitally record at least one of the term's speeches in class or lab to offer students additional presentation feedback. Students often watch and self-critique their speeches on their own. Peers often give only written feedback on classroom presentations or completed…

A widely used method for teaching children with autism is applied behavior analysis (ABA), and a main component of ABA programming is discrete-trials teaching (DTT). Using a modified multiple-baseline design across participants, we assessed the effectiveness of a DTT self-instructional package (Fazzio & Martin, 2007) for teaching four pairs of…

This article explores the impact of an augmented reality iPad-based mobile game, called The Great STEM Caper, on students' interaction at a science center. An open-source, location-based game platform called ARIS (i.e. Augmented Reality and Interactive Storytelling) was used to create an iPad-based mobile game. The game used QR scan codes and a…

Opportunities for language learners to access authentic input and engage in consequential interactions with native speakers of their target language abound in this era of computer mediated communication. Synchronous audio/video calling software represents one opportunity to access such input and address the challenges of developing pragmatic and…

The use of humour in teaching and learning can be contentious, with some authors suggesting that the efficacy of humorous materials is mediated by the culture of the student. Nevertheless, humour represents a potential vehicle for the introduction of active learning in a classroom setting, as judicious use of humour may lead to a more relaxed…
