The transition from school services to adulthood can be particularly difficult for many adolescents with autism spectrum disorders (ASD). Although some individuals with ASD are able to successfully transition, most are faced with significant obstacles in multiple areas as they attempt to negotiate their way into college, work, community…

In this study, students' use of a new educational Web portal was evaluated with particular emphasis on searching and browsing strategies. The effects and implications of a federated search system are also discussed. Fifty-four students, ranging from 5th to 12th grade, were given five tasks to complete using the SchoolRooms interface. The tasks…

Only the most dedicated super-searchers are motivated to learn and control command systems, like DialogClassic, that rely on the user to input complex search strategies. Infrequent searchers and most end users choose interfaces that do some of the work for them and make the search process appear easy. However, the easier a good interface seems to…

Although information searching in hypermedia environments has become a new important problem solving capability, there is not much known about what types of individual characteristics constitute a successful information search behavior. This study mainly investigated which of the 2 factors, 1) natural characteristics (cognitive style), and 2)…

The idea of "information commitments" refers to both learners' online searching strategies and the evaluative standards that students use to assess the accuracy and usefulness of information in web-based learning environments. Based upon the results of a pioneering and qualitative study on information commitments, this study aimed to develop an…

Information retrieval in the context of virtual universities deals with the representation, organization, and access to learning objects. The representation and organization of learning objects should provide the learner with an easy access to the learning objects. In this article, we give an overview of the ONES system, and analyze the relevance…

Federated search products are becoming more and more prevalent in academic libraries. What are the implications of this phenomenon for instruction librarians? An analysis of federated search products using the "Information Literacy Competency Standards for Higher Education" and a thorough review of the literature offer insight concerning whether…

In this article, the author vitalizes her British literature course by asking seniors to investigate, through an I-Search paper, the concept of heroism. Students research a historic or contemporary individual, drawing on their understanding of heroic literary figures previously studied, and interview family, community members, and others connected…

Among librarians, government information has a reputation for being a valuable but underused resource. A literature review of undergraduate citation studies, however, reveals that the use of government information has apparently increased so much for some subject areas that, after books and journals, it has become one of the most frequently used…

Examines a number of searches dealing with the synthesis of organic compounds which the author performed on CA CONDENSATES and CASIA data bases (on DIALOG) at the request of users. Results show that a combined use provides the users with a more satisfying result even if the larger output contains some undesired citations. (JD)

Offers advice on which search techniques work best, and lists eight specific strategies on recovering from a search that does not go as expected. A sidebar describes expanding a search and limiting results. (Author/PEN)

This paper compares the subject indexing on articles pertaining to Immanuel Kant, agriculture, and aging that are found simultaneously in Humanities Index, Academic Search Elite (EBSCO) and Periodicals Research II (Micromedia ProQuest), in order to show that there are substantial variations in the depth and quality of indexing in these databases.…

Research suggests that the World Wide Web (WWW) represents the intersection of at least two domains: content and technology. This investigation was designed to examine the relationship between prior knowledge and WWW browsing outcomes (i.e., navigation behavior and knowledge gain) within the context of a genetics Web site. Students randomly…

The need to support users of the Internet with the selection of information is becoming more important. Learners in complex, self-organising Learning Networks have similar problems and need guidance to find and select most suitable learning activities, in order to attain their lifelong learning goals in the most efficient way. Several research…

Enriching factor rotation algorithms with the capacity to conduct repeated searches from random starting points can make the tendency to converge to optima that are merely local a way to catch rotations of the input factors that might otherwise elude discovery. Use of the HYBALL computer program is discussed. (SLD)
