    Next Generation Teaching and Learning ??? Technologies and Trends

    Get PDF
    The landscape of teaching and learning has been radically shifted in the last 15 years by the advent of web technologies, which enabled the emergence of Learning Management Systems (LMS). These systems changed the educational paradigm by extending the classroom borders, capturing and persisting course content and giving instructors more flexibility and access to students and other resources. However, they also constrained and limited the evolution of teaching and learning by imposing a traditional, instructional framework. With the advent of Web 2.0 technologies, participation and collaboration have become predominant experiences on the Web. The teaching and learning community, as a whole, has been late to capitalize on these technologies in the classroom. Part of this trend is due to constraints in the technology (LMS), and part is due to the fact that participatory media tools require an additional shift in educational paradigms, from instructional, on-the-pulpit type of teaching, to a student-centered, adaptive environment where students can contribute to the course material and learn from one another. This panel will discuss the next generation of teaching and learning, involving more lightweight, modular systems to empower instructors to be flexible, explore new student-centered paradigms, and plug and play tools as needed. We will also discuss how the iSchools are and should be increasingly involved in studying these new forms, formulating best practices and supporting the needs of teachers as they move toward more collaborative learning environments

    The Evolution of the Field of Human Resource Information Systems: Co-Evolution of Technology and HR Processes

    In this paper, we review the professional and academic development of the human resource information systems (HRIS) field to assess its progress and suggest ways for moving research forward. To do so, we examine the interplay between the evolution of technology and the HR field through four key eras of technology: 1) mainframe, 2) client server, 3) ERP and Web-based systems, and 4) cloud-based systems. In each era, we discuss how HR practices and requirements drove the need for the use of these systems and how these systems allowed the HR field to evolve. In addition, we trace the HRIS subfield and its relation to the technological evolutions occurring in the HR field. Somewhat surprisingly, we found that much of the research on the use of technology to support HR has occurred only in the last 15-20 years as a response to the use of the Web as a medium for delivering HRIS. We conclude by discussing how scholars from the information systems and human resources fields can come together to help advance HRIS

    Thesauri and Semantic Web: Discussion of the Evolution of Thesauri toward their Integration With the Semantic Web

    Get PDF
    15 p.Thesauri are Knowledge Organization Systems (KOS), that arise from the consensus of wide communities. They have been in use for many years and are regularly updated. Whereas in the past thesauri were designed for information professionals for indexing and searching, today there is a demand for conceptual vocabularies that enable inferencing by machines. The development of the Semantic Web has brought a new opportunity for thesauri, but thesauri also face the challenge of proving that they add value to it. The evolution of thesauri toward their integration with the Semantic Web is examined. Elements and structures in the thesaurus standard, ISO 25964, and SKOS (Simple Knowledge Organization System), the Semantic Web standard for representing KOS, are reviewed and compared. Moreover, the integrity rules of thesauri are contrasted with the axioms of SKOS. How SKOS has been applied to represent some real thesauri is taken into account. Three thesauri are chosen for this aim: AGROVOC, EuroVoc and the UNESCO Thesaurus. Based on the results of this comparison and analysis, the benefits that Semantic Web technologies offer to thesauri, how thesauri can contribute to the Semantic Web, and the challenges that would help to improve their integration with the Semantic Web are discussed.S

    Lo stato dell’arte dell’innovazione tecnologica per le architetture web: presente e futuro per Archeologia e Calcolatori

    The paper illustrates the recent evolution of web architectures and the choices made for the web portal of ‘Archeologia e Calcolatori’. The website needed an urgent restyling to update its ASP platform, even though for 15 years it had performed its interactive work very well. Today, the ASP language is no longer supported by Microsoft and the infrastructural choices of the CNR are and will be increasingly oriented towards the world of open source and LAMP architectures (Linux, Apache, MySQL, PHP/Phyton). For this reason, a transformation was not only suggested, but vital. It was therefore decided to completely renew the website, a task consisting of about 70 physical pages to be rewritten in PHP. This work transformation has helped to pave the way for new technologies that today are modifying the web architecture of the entire WWW and that will soon allow us to implement new services and functions. Particular attention was paid to the most significant phenomena in the innovative technological panorama of Web Information Systems, with particular emphasis on the Semantic Databases and the new RIA (Rich Internet Application) technologies, the latter a splendid evolution of client-side web architectures

    Evolutionary ecology in-silico: Does mathematical modelling help in understanding the "generic" trends?

    Get PDF
    Motivated by the results of recent laboratory experiments (Yoshida et al. Nature, 424, 303-306 (2003)) as well as many earlier field observations that evolutionary changes can take place in ecosystems over relatively short ecological time scales, several ``unified'' mathematical models of evolutionary ecology have been developed over the last few years with the aim of describing the statistical properties of data related to the evolution of ecosystems. Moreover, because of the availability of sufficiently fast computers, it has become possible to carry out detailed computer simulations of these models. For the sake of completeness and to put these recent developments in the proper perspective, we begin with a brief summary of some older models of ecological phenomena and evolutionary processes. However, the main aim of this article is to review critically these ``unified'' models, particularly those published in the physics literature, in simple language that makes the new theories accessible to wider audience.Comment: 28 pages, LATEX, 4 eps figure

    Managing evolution and change in web-based teaching and learning environments

    Get PDF
    The state of the art in information technology and educational technologies is evolving constantly. Courses taught are subject to constant change from organisational and subject-specific reasons. Evolution and change affect educators and developers of computer-based teaching and learning environments alike – both often being unprepared to respond effectively. A large number of educational systems are designed and developed without change and evolution in mind. We will present our approach to the design and maintenance of these systems in rapidly evolving environments and illustrate the consequences of evolution and change for these systems and for the educators and developers responsible for their implementation and deployment. We discuss various factors of change, illustrated by a Web-based virtual course, with the objective of raising an awareness of this issue of evolution and change in computer-supported teaching and learning environments. This discussion leads towards the establishment of a development and management framework for teaching and learning systems

    Matching demand and offer in on-line provision: A longitudinal study of monster.com

    Get PDF
    This is the post-print version of the final published paper that is available from the link below.When considering the jobs market, changes or recurring trends for skilled employees expressed by employers' needs have a tremendous impact on the evolution of website content. On-line jobs sites adverts, academic institutions and professional development “standard bodies” all share those needs as their common driver for contents evolution. This paper aims, on one hand, to discuss and to analyse how current needs and requirements (“demand”) of IT skills in the UK job market drive the contents of different types of websites, in turn analysing whether this demand changes and how. On the other hand, it is studied what the UK higher education institutions have to offer to fulfill this demand. The results found analysing the evolution of the largest on-line job centre (www.monster.com), and the websites of selected UK academic institutions, demonstrate that often what is requested by UK industries is not clearly offered by UK institutions. Given the prominence of monster.com in the global economy, these results could provide a meaningful starting point to support curricula development in UK, as much as worldwide
