This article challenges educational computing researchers and teacher educators to consider a merger between universal design for learning and technological pedagogical content knowledge to create a practitioners' model to prepare teachers to graduate with the knowledge, skills, and dispositions needed to teach the full spectrum of learners.…

A field enquiry in French distance education allows us to analyze the evolution of a specific institution towards new public management: Parallel to a trend of free courseware and open education, there is a paradoxical reality of distance education monetization. Whereas history shows how traditional French education is a state controlled public…

The National Broadband Plan (NBP) recently announced by the Federal Communication Commission visualizes a significantly enhanced commitment to public computing centers (PCCs) as an element of the Commission's plans for promoting broadband availability. In parallel, the National Telecommunications and Information Administration (NTIA) has…

Multimedia is developing fast due to the convergence of different media (text, data. graphics, video, audio) into a common digital platform, and due to the convergence of telecommunications, television, and computing. Parallel to these technical convergencies is another set of developments in work and leisure that is opening up new markets for…

m-Learning is made possible by the existence and application of mobile hardware and networking technology. By exploring the capabilities of these technologies, it is possible to construct a picture of how different components of m-Learning can be implemented. This paper will explore the major technologies currently in use: portable digital…

Energy consumption by computer systems has emerged as an important concern, both at the level of individual devices (limited battery capacity in mobile systems) and at the societal level (the production of Green House Gases). In parallel architectures, applications may be executed on a variable number of cores and these cores may operate at…

Partnering with museums and Indiana University, the American Indian Higher Education Consortium (AIHEC) has helped create e-Humanity, an online cultural portal. Launched in June 2011, E-Humanity represents the beginning of a new form of cultural institution, one that will blur the lines between traditional museum authority and collections of…

Grounded on object filtering, automatic indexing, and co-occurrence analysis, an experiment was performed using a parallel supercomputer to analyze over 400,000 abstracts in an INSPEC computer engineering collection. A user evaluation revealed that system-generated thesauri were better than the human-generated INSPEC subject thesaurus in concept…

High performance, massively-parallel multi-physics simulations are built on efficient mesh data structures. Most data structures are designed from the bottom up, focusing on the implementation of linear algebra routines. In this thesis, we explore a top-down approach to design, evaluating the various needs of many aspects of simulation, not just…

It is a global concern that the number of students in computing-related fields has been decreasing in the last few years. As a way to improve this situation, several institutions have been implementing programs to attract and keep students in science and technology majors. This work describes a high-performance computing (HPC) course intended for…

Combinatorial scientific computing plays an important enabling role in computational science, particularly in high performance scientific computing. In this thesis, we will describe our work on optimizing matrix-vector multiplication using combinatorial techniques. Our research has focused on two different problems in combinatorial scientific…

There are millions of people worldwide--of all ages, conditions, backgrounds, and motivations--with significant learning needs. Unfortunately, traditional education is not efficient enough to meet these needs. That is, the available educational resources are not fully exploited to help cover the demand. There is an increasing need for large-scale…

Empirically derived semantic feature norms categorized into different types of knowledge (e.g., visual, functional, auditory) can be summed to create number-of-feature counts per knowledge type. Initial evidence suggests several such knowledge types may be recruited during language comprehension. The present study provides a more detailed…

This dissertation explores similarity effects in assimilation, proposing an Attraction Framework to analyze cases of parasitic harmony where a trigger-target pair only results in harmony if the trigger and target agree on other features. Attraction provides a natural model of these effects by relating the pressure for assimilation to the…

Change growing from technological innovation occasions both excitement and apprehension for all educators. This is especially so in music education. For music educators, as many new wants as new worries accompany these changes. In this article, the author argues for the critical engagement of the music education profession to amplify positive…
