Abstract

The Internet can be a valuable tool allowing distance learners to access information not available locally. Search engines are the most common means of locating relevant information an the Internet, but to use them efficiently students should be taught the basics of searching and how to evaluate the results. This article briefly reviews how Search engines work, studies comparing Search engines, and criteria useful in evaluating the quality of returned Web pages. Research indicates there are statistical differences in the precision of Search engines, with AltaVista ranking high in several studies. When evaluating the quality of Web pages, standard criteria used in evaluating print resources is appropriate, as well as additional criteria which relate to the Web site itself. Giving distance learners training in how to use Search engines and how to evaluate the results will allow them to access relevant information efficiently while ensuring that it is of adequate quality.

Abstract

The Internet, particularly the Web, is a wonderful free source of information that can vastly improve the array of resources available to library patrons. Unfortunately, not all information is honest and accurate, and some of it is not suitable for certain age groups. Students using the Web for research often come upon unsuitable sites. We can get around this by constructing Web learning environments containing safe sites for students. These learning experiences include WebQuests, Pathfinders, Treasure Hunts, Scavenger Hunts, and Tracks.

Abstract

Purpose - The purpose of this paper is to review recent developments in educational informatics relating to the provision by information systems of pedagogical support to web-based learners, and to propose further investigation of the feasibility and potential value of web-based "conversational" information systems to complement adaptive hypermedia and information retrieval systems. Design/methodology/approach - The potential of Pask's conversation theory is considered as a potentially useful framework for the development of information systems capable of providing pedagogical support for web-based learners, complementary to that provided by existing computer-assisted learning and adaptive hypermedia systems. The potential role and application of entailment meshes are reviewed in relation to other forms of knowledge representation including classifications, semantic networks, ontologies and representations based on knowledge space theory. Findings - Concludes that conversation theory could be a useful framework to support the development of web-based "conversational" information that would complement aspects of computer-assisted learning, adaptive hypermedia and information retrieval systems. The entailment mesh knowledge representation associated with conversation theory provides the potential for providing particularly rich pedagogical support by virtue of its properties of cyclicity, consistency and connectivity, designed to support deep and enduring levels of understanding. Research limitations/implications - Although based on a considerable body of theoretical and empirical work relating to conversation theory, the paper remains speculative in that the gap is still great between, on the one hand, what has so far been achieved and, on the other, the practical realisation of its potential to enhance web-based learning. Much work remains to be done in terms of exploring the extent to which procedures developed and benefits found in relatively small-scale experimental contexts can effectively be scaled to yield enhanced support for "real world" learning-related information behaviour. Originality/value - The ideas of Pask, discussed in this paper, are capable of guiding the structuring of information according to parameters designed to facilitate deep and enduring understanding via interactive "conversational" engagement between the conceptual structures of information source authors and learners. If one can scale Pask's work to "real world" learning-related information behaviour, one can increase the range of web-based information systems and services capable of providing pedagogical support to web-based learners.

Abstract

Purpose - The paper focuses on e-learning from an information literacy perspective and promotes the view that information literacy education needs to play a central role within any e-learning initiative. The main aim of this paper is therefore to present the claim that e-learning must be supported by an information literacy framework to enable an effective interaction between learners, information literacy educators and complex information environments. Design/methodology/approach - Literature-based analysis of the main issues covered. These include: the challenges generated by the proliferation of digital information and the consequent need for information literacy education to counteract the phenomenon of information overload; the comparison of the information literacy approach promoted by Australia and the USA with the ICT-skills approach adopted by the UK. Findings - Examples of information literacy frameworks promoted by the Association of College and Research Libraries and the Australian and New Zealand Institute are used to illustrate the strong association between the "learning-how-to-learn" model, lifelong learning and the global knowledge economy. The UK perspective on e-learning reveals a similar lifelong-learning agenda, although in this case ICT skills, not information literacy, are identified as a priority, even though the effectiveness of lifelong-learning competences depends on the learner's ability to interact with constantly changing information and knowledge structures. Originality/value - The paper promotes the view that a fully-fledged information literacy education, based on nationally recognised standards, must underpin any pedagogical initiative especially in the area of e-learning which requires the learners' active engagement with a wide range of information sources and formats. The paper is therefore relevant to those professionals involved in the development of policy and provision at higher education level.

Abstract

The knowledge represented in learning materials for the sciences is typically organized around term-based or "weakly-structured" models of concepts and their interrelationships. We introduce a "strongly-structured" model of scientific concepts that provides the foundation for a knowledge base (KB) of concept representations. An extension of the Alexandria Digital Library employs such a KB, together with associated collection and services, to support undergraduate leaming.

Abstract

The virtual university environment provides librarians with new opportunities to contribute to the educational process. Building on the success of team-teaching a traditional liberal arts core course with composition and communications faculty, librarians and a communications professor worked together to integrate the Association of College & Research Libraries (ACRL) Information Literacy Competency Standards for Higher Education (2000) into the online environment. The resulting graduate-level course in multimedia literacy assembled faculty and curriculum resources normally untapped in traditional classrooms. All five information literacy standards covering need, access, evaluation, use and the social, economic, legal, and ethical issues surrounding information use were addressed. Readings and threaded discussions about intellectual property, fair use of copyrighted materials, the evaluation of free and fee-based Web information and Web page design and construction prepared students to work in groups to design and construct Web sites. Students also completed a capstone project in the form of individual Web portfolios, which demonstrated the information and multimedia principles they learned in the class. Assessment of information literacy skills occurred through the analysis of student discussion, evaluative annotations, Web site assignments, perception surveys, and a master's level comprehensive exam question. What was learned in this course will serve as a model for future collaborative partnerships in which faculty and librarians work together to ensure that students who learn from a distance truly master information literacy competencies.

Abstract

Wie müssen wir virtuelle Rundgänge und Online-Tutorials gestalten, damit sie ihre Zielgruppe auch wirklich erreichen? Worauf müssen wir bei einer guten Präsentation unseres OPACs achten? Was machen wir mit großen Schülergruppen? Diesen Fragen stellten sich insgesamt 22 Bibliothekarinnen und Bibliothekare in Münster und Köln während zweier Fortbildungsveranstaltungen des HBZ im Juni 2003. Ziel der jeweils zweitägigen Workshops, die in Zusammenarbeit mit der Adhoc-Arbeitsgruppe "Informationskompetenz" der AG der Universitätsbibliotheken im VBNW konzipiert wurden, waren Konzepte und erste Schritte zur Umsetzung von elektronischen Angeboten zur Vermittlung von Bibliotheksbzw. Informationskompetenz. Dem voraus ging die konstruktive Bewertung von bereits existierenden Materialien, die zum einen von den Teilnehmern aus ihren Bibliotheken mitgebracht wurden, zum anderen über Bibliotheks-Homepages abrufbar waren. Die Teilnehmer, die in ihren Bibliotheken bereits Benutzerschulungen konzipieren und durchführen, beschäftigten sich dabei in Gruppen u.a. mit den Themen - Virtuelle Rundgänge, - Online-Tutorials - Bibliothekseinführungen für Schüler und Erstsemester - Präsentationen von Online-Katalog und Methoden zur Literatursuche. Im Folgenden werden einige wesentliche und manchmal durchaus kontrovers diskutierte Ergebnisse und Thesen wiedergegeben, die sich aus der Arbeit der Teilnehmer ergeben haben. Sie erheben keinen Anspruch auf Ausgewogenheit oder Vollständigkeit, können aber als Anregungen und Diskussionsgrundlage für zukünftige Projekte dienen.

Abstract

The increasing spread of Internet technology has highlighted the need for a better understanding of the fundamental issues concerning human users in a virtual space. Despite the great degree of navigational freedom, however, not all hypermedia users have the capability to locate information or assimilate internal knowledge. Research findings suggest that this type of problem could be solved if users were able to hold a cognitive overview of the hypermedia structure. How a learner can acquire the correct structural knowledge of online information has become an important factor in learning performance in a hypermedia environment. Variables that might influence learners' abilities in structuring a cognitive overview, such as users' cognitive styles and the different ways of representing information, should be carefully taken into account. The results of this study show that the interactions between information representation approaches and learners' cognitive styles have significant effects on learners' performance in terms of structural knowledge and feelings of disorientation. Learners' performance could decline if a representational approach that contradicts their cognitive style is used. Finally, the results of the present study may apply only when the learner's knowledge level is in the introductory stage. It is not clear how and what type of cognitive styles, as well as information representation approaches, will affect the performance of advanced and expert learners.

Abstract

The librarians and information specialists play the very important role in the Information Society. They perform a greater variety of tasks than before. That is why the range of knowledge and the skills, they should learn, considerably extends. Therefore the problems arose: how to educate the librarians and information specialists? Which methods and techniques are the most suitable and profitable? How to organize the education process to give them as much experience as possible? The usage of modern methods and tools, especially the e-learning systems, may be the right solution. That paper presents the experiences with the Virtual Learning Environment at Nicolaus Copernicus University. The author is involved in the e-learning process as a teacher of various subjects and as an administrator of Moodie (Modular Object-Oriented Dynamic Learning Environment), which is used as an e-learning platform. The paper describes the process of preparing resources and the methods of using them in education in the field of Information Science and Librarianship. The special attention is paid to knowledge gained and skills trained by students as well as by teachers. Their impressions are shown. The advantages and disadvantages of e-learning are discussed in details.
