We compared the effects of a commercially-available children's video relative to an instructor-created video model on the acquisition of play skills with three children diagnosed with an autism spectrum disorder. Each participant was exposed to one commercially-available video model for one play scenario and one instructor-created video for a…

A basic and affordable experimental apparatus is described that measures the static contact angle of a liquid drop in contact with a solid. The image of the drop is made with a simple digital camera by taking a picture that is magnified by an optical lens. The profile of the drop is then processed with ImageJ free software. The ImageJ contact…

The author spent many years in the classroom as a traditional technical education teacher. He was always attracted to emerging technologies, and visual technologies in particular interested him. In this article, he shares some of his experiences with setting up and running a very successful TV/video technology program.

College students participated in a study on the "psychology of note taking" during which they took notes on video content and later completed a multiple-choice test on the material. Researchers assigned 71 participants to either the ringing condition (the video was disrupted by a ringing cell phone) or the control condition (no cell phone rings…

Baby media have exploded in the past decade, and children younger than 2 are showing increased use of these baby media. This paper examines the historical evidence of babies' use of television since the 1950s as well as the various factors that have given rise to the current increase in screen media for babies. We also consider the ubiquitous role…

We assessed the reliability and validity of the discrete-trials teaching evaluation form (DTTEF), a 21-item checklist for assessing instructors conducting discrete-trials teaching (DTT). In Phase 1, six consultants in an applied behavior analysis program for children with autism rated the 21 components of the DTTEF with a mean of 6.2 on a 7-point…

This paper examines the use of peer-videoing in the classroom as a means of promoting reflection among student teachers. Ten pre-service teachers participating in a teacher education programme in a university in the Republic of Ireland and ten pre-service teachers participating in a teacher education programme in a university in the North of…

In this paper, we use the concept of chronotope to analyse the co-construction of spatial and temporal frameworks during collaborative interaction. A chronotope is a genre of movement or pacing in the space that participants adopt over the temporal duration of an activity. We look in particular at the conjunction point of time and space as…
