Undeniably omnipresent in our everyday lives, electronic signal compression is a classical example that illustrates the ubiquity of mathematics in high-end technology and sciences. When dealing with piles of files, it is essential that each file takes up as little storage space as possible while maintaining quality. The cloud-based--available…

The Doppler effect is one of the recurring themes in college and high school classes. In order to contextualize the topic and engage the students in their own learning process, we propose a simple and easily accessible activity, i.e. the analysis of the videos available on the internet by the students. The sound of the engine of the vehicle…

This column provides background science information for elementary teachers. When the author was young he used to think that the ideal design for a concert hall would contain walls that were composed of sound-absorbing material, like foam or egg cartons or such. He noticed, though, that this was not the case. Most concert halls contain curtains…

The primary purpose of this study was to examine the potential of LOw LAtency (LOLA), a low latency audio visual technology designed to allow simultaneous music performance, as a distance learning tool for musical styles in which synchronous playing is an integral aspect of the learning process (e.g., jazz, folk styles). The secondary purpose was…

Communication underwater is challenging because of the inherent characteristics of the media. First, common radio frequency (RF) signals utilized in wireless communications cannot be used under water. RF signals are attenuated in such as way that RF communication underwater is restricted to very few meters. As a result, acoustic-based…

In today's world of too much information, context--not content--is king. This proposal is for the development of an unparalleled sonic analysis tool that converts audio files into musical score notation and a Web site (API) to collect manage and preserve information about the musical sounds analyzed, as well as music scores, videos, and articles…

A major strand of science and technology studies in recent decades has related to the social construction of technology (SCOT) movement, whose adherents maintain that technological systems are determined just as much by social forces as by technological ones. Taking this SCOT notion as a starting point, and putting a focus on the user, this paper…

The transportation field has for many years been dominated by engineers and other technical specialists. This article describes the Sustainable Mobility Learning Lab (SMLL), a Web-based tool designed to support classroom and university outreach activities to help initiate a more inclusive, nontechnical discussion about the role of transportation…

This article describes the implementation and evaluation of a learning objects based computer aided system for an advanced engineering course at Ghent University, Belgium. A new syllabus concept was introduced: students had access to a Web-delivered component and received an identical printed component as two sources of information additional to…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
