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…

This study examined the effects of collaboration mode (collocated versus non-collocated videoconferencing-mediated) on team learning and team interaction quality in a team-based problem solving context. Situated learning theory and the theory of affordances are used to provide a framework that describes how technology-mediated collaboration…

Field trips have become less common due to issues including budget constraints and large class sizes. Research suggests that virtual field trips can substitute for field visits, but the role of webcams has not been evaluated. To investigate the potential for webcams to substitute for field trips, participants viewed urban and physical landscapes…

Exergames (active video games that require kinesthetic movement) played in proximity to other players or against a gaming machine have been linked to positive increases in cognitive functioning. This study tested to see if remote exergame play over the Internet had an impact similar to exergames that are played in proximity. The study shows that…

College students are bombarded with technological images in every facet of their education. From simple Powerpoint presentations to live interactive distance learning environments, the world in which the authors are teaching is changing on a daily basis. Colleges and universities have turned to distance learning as one way to provide flexibility…

Recent studies indicate that being intensely imitated for a brief period of time increases social interest among children with autism. The aim of this study was to replicate and extend these findings. Twenty children with an autism spectrum disorder (ASD) were randomly assigned to one of two interaction strategies: imitation (n = 10) or contingent…
