The aim of the current study was to examine the way in which preschool children deal with the concept of sound. For this purpose, a study was carried out in the context of detecting and categorizing the mental representations among young children of sounds which propagate through space from source to the receiver. Specifically, 91 preschool…

Educational practices are constantly adjusting to technological advances, in order to improve their effectiveness in delivering knowledge and preparing students for the challenges of modern digital society. Electronic games and augmented reality environments are two such media that can shape powerful modes of interactive and immersive experiences.…

While little is known about how young children understand noise and its environmental aspects, this topic is suggested to be included in science curricula from early years on. To investigate if and to what extent preschool children's level of noise awareness could be improved the 'Young Noise Researchers' educational scenario was designed,…

Previous work on children's acquisition of complex sequences points to a tendency for affricates to be acquired before clusters, but there is no clear evidence of a difference in order of acquisition between clusters with /s/ that violate the Sonority Sequencing Principle (SSP), such as /s/ followed by stop in onset position, and other clusters…

Digital signal processing (DSP) has been an integral part of most electrical, electronic, and computer engineering curricula. The applications of DSP in multimedia (audio, image, video) storage, transmission, and analysis are also widely taught at both the undergraduate and post-graduate levels, as digital multimedia can be encountered in most…

The purposes of this study were to derive nasalance norms for monolingual Greek speakers, to examine nasalance scores as a function of gender and to draw cross-linguistic comparisons based on normative data. Participants read aloud a corpus of linguistic material, consisting of (1) a nasal text, an oral text and a balanced text; (2) a set of nasal…

This paper focuses on connecting natural sciences education with Cultural Historical Activity Theory (CHAT). In this sense, natural sciences education is considered as a lifelong learning procedure, not seen as an individual but as a collective activity. Moreover, learning becomes a human activity in which theory and praxis are strongly connected…

The general purpose of the present study was to test the effectiveness of various psycho-acoustic manipulations for the understanding of specific information (typographic attributes such as bold and italic) which was included in texts by individuals with and without blindness. Thirty blind and thirty sighted students participated and were asked to…

The current investigation examined the development of voice onset time (VOT) in Standard-Greek (SG) and Cypriot-Greek (CG)-speaking children at age levels 2;0-2;5, 2;6-2;11, 3;0-3;5, and 3;6-4;0 years. SG presents with a two-way voicing contrast (voiced and voiceless unaspirated stops) whereas CG is a three-way contrast dialect containing…

This study examined the perceptions held by sighted students and students with visual impairments of the intelligibility and comprehensibility of similar acoustic patterns produced by synthetic speech. It determined the types of errors the students made and compared the performance of the two groups on auditory discrimination and comprehension.

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…
