Technology training in preservice education programs : a review of the literature
Education is radically changing with the dawn of the information age, where the ability to access, analyze, and manipulate information is a basic survival skill. To become more technologically adept, elementary and secondary schools must provide technical training to their students. However, trained students are the result of trained professionals. Recognizing the burgeoning need to provide skilled professionals, institutions of teacher education are integrating educational technology programs in preservice education.
This review of the literature reports on technology implementation at teacher training institutions where educational technology is being infused into the preservice curriculum through adherence to guidelines from ISTE and NCATE. Course content consisting primarily of computer and media is taught by faculty who must overcome barriers to their technical illiteracy. Best practice models of technology integration are formed by student-centered learning situations that involve constructivism and collaboration
VISIR: experiences and challenges
It is of crucial importance the integration of practical
sessions in engineering curricula owing to their significant
role in understanding engineering concepts and scientific
phenomena. However, the lack of practical sessions due
to the high costs of the equipment and the unavailability of
instructors has caused a significant declination in experimentation
in engineering education. Remote laboratories
have tackled this issues providing online reusable and
shared workbenches unconstrained by neither geographical
nor time considerations. Thereby, they have extremely proliferated
among universities and integrated into engineering
curricula over the last decade. This contribution compiles
diverse experiences based on the deployment of the remote
laboratory, Virtual Instrument Systems in Reality (VISIR),
on the practices of undergraduate engineering grades at
various universities within the VISIR community. It aims to
show the impact of its usage on engineering education concerning
the assessments of students and teachers as well. In
addition, the paper address the next challenges and future
works carried out at several universities within the VISIR
community
Fast parallel volume visualization on cuda technology
In the medical diagnosis and treatment planning, radiologists and surgeons rely
heavily on the slices produced by medical imaging scanners. Unfortunately, most of
these scanners can only produce two dimensional images because the machines that
can produce three dimensional are very expensive. The two dimensional images from
these devices are difficult to interpret because they only show cross-sectional views
of the human structure. Consequently, such circumstances require highly qualified
doctors to use their expertise in the interpretation of the possible location, size or
shape of the abnormalities especially for large datasets of enormous amount of slices.
Previously, the concept of reconstructing two dimensional images to three
dimensional was introduced. However, such reconstruction model requires high
performance computation, may either be time-consuming or costly. Furthermore,
detecting the internal features of human anatomical structure, such as the imaging of
the blood vessels, is still an open topic in the computer-aided diagnosis of disorders
and pathologies. This study proposed, designed and implemented a visualization
framework named SurLens with high performance computing using Compute
Unified Device Architecture (CUDA), augmenting the widely proven ray casting
technique in terms of superior qualities of images but with slow speed. Considering
the rapid development of technology in the medical community, our framework is
implemented on Microsoft .NET environment for easy interoperability with other
emerging revolutionary tools. The Visualization System was evaluated with brain
datasets from the department of Surgery, University of North Carolina, United
States, containing 109 datasets of MRA, T1-FLASH, T2-Weighted, DTI and
T1-MPRAGE. Significantly, at a reasonably cheaper cost, SurLens Visualization
System achieves immediate reconstruction and obvious mappings of the internal
features of the human brain, reliable enough for instantaneously locate possible
blockages in the brain blood vessels without any prior segmentation of the datasets
Learning objects and learning designs: an integrated system for reusable, adaptive and shareable learning content
This paper proposes a system, the Smart Learning Design Framework, designed to support the development of pedagogically sound learning material within an integrated, platform-independent data structure. The system supports sharing, reuse and adaptation of learning material via a metadata-driven philosophy that enables the technicalities of the system to be imperceptible to the author and consumer. The system proposes the use of pedagogically focused metadata to support and guide the author and to adapt and deliver the content to the targeted consumer. A prototype of the proposed system, which provides proof of concept for the novel processes involved, has been developed. The paper describes the Smart Learning Design Framework and places it within the context of alternative learning object models and frameworks to highlight similarities, differences and advantages of the proposed system
Toward a Semiotic Framework for Using Technology in Mathematics Education: The Case of Learning 3D Geometry
This paper proposes and examines a semiotic framework to inform the use of technology in mathematics education. Semiotics asserts that all cognition is irreducibly triadic, of the nature of a sign, fallible, and thoroughly immersed in a continuing process of interpretation (Halton, 1992). Mathematical meaning-making or meaningful knowledge construction is a continuing process of interpretation within multiple semiotic resources including typological, topological, and social-actional resources. Based on this semiotic framework, an application named VRMath has been developed to facilitate the learning of 3D geometry. VRMath utilises innovative virtual reality (VR) technology and integrates many semiotic resources to form a virtual reality learning environment (VRLE) as well as a mathematical microworld (Edwards, 1995) for learning 3D geometry. The semiotic framework and VRMath are both now being evaluated and will be re-examined continuously

Designing Open and Distance Learning for Teacher Education in Sub-Saharan Africa: A toolkit for educators and planners
Everyone remembers a good teacher. Good teachers are the key to educational expansion and improvement. In many countries in Sub-Saharan Africa, there is an urgent need to expand the number of primary and secondary teachers. In all African countries, there is an equally important need to improve the quality of teaching. To achieve this, it is clear that new approaches to teacher education are essential. Existing institutions of teacher education will continue to play an important role, but, alone, they will not meet the goals of Education for All (EFA) by 2015.
It is fortunate that, just as the twin needs to improve the quantity and quality of teachers become imperative, so new forms of education and training are becoming available. The world is witnessing a revolution in information and communication technologies (ICTs), which can offer training and support of a type and at a cost hitherto impossible to consider, and thus, must be fully explored given the scale and urgency of demand. In doing so, however, it will be necessary to build on existing and well-tested strategies, including the best models of open and distance learning.
This toolkit is the third in a series of recent publications by the Africa Region Human Development Department of the World Bank to share knowledge and experience on how distance education and ICTs can support education in Sub-Saharan Africa. It emphasizes the rigorous process by which new forms of distance-education programs for teacher education can be planned and implemented. The best models of established programs are considered along with the potential for incorporating, as the means become available, new modes of communication. Most forms of teacher education, particularly those concerned with qualification upgrading and ongoing professional development, will have to be based in schools. The authors demonstrate how school-based programs, appropriately resourced and supported, have the potential not only to raise significantly the number and quality of teachers, but also to improve classroom practice and school organization, generally. The guidance and advice, which is drawn from many years of experience in design and implementation, and embraces a range of case studies from across the region, will be of considerable value to those preparing new policies and programs of teacher education and to those seeking to improve existing programs
Technology\u27s impact on student learning in grades K-8
Many research studies have found that educational technology that is accessible, equitable, and properly used can make a significant difference in students\u27 academic performance. The purpose of this study was to determine if Wildwood Crest Memorial School had a well-orchestrated technology plan, which addressed the technological needs of students and teachers and to determine what impact technology had on student learning. A survey developed by the Southeast and Islands Regional Technology in Education Consortium (SEIR*TEC) was used to collect data from students and teachers. An analysis of the data found that the district goals and objectives were being met with the integration of technology into the curriculum and instruction. Technology as a tool was used to stimulate higher order thinking and problem-solving skills. Students\u27 mastery of academic content improved significantly utilizing collaborative and globalized learning and, as such, accelerated, enriched, and deepened students\u27 understanding of the curriculum
