Artificial neural networks (ANN), part of artificial intelligence, are discussed. Such networks are fed sample cases (training sets), learn how to recognize patterns in the sample data, and use this experience in handling new cases. Two cognitive roles for ANNs (intelligent filters and spreading, associative memories) are examined. Prototypes…

Proposes improved, more computer-intensive statistical techniques using bootstrap and permutation tests for analyzing results of student evaluations of teaching. Application of these methods resulted in narrower (more precise) confidence intervals and larger significance levels than more classical methods. Results indicate the new techniques…

A study investigated the relationship of 35 high school students' online catalog search performance and their academic achievement and verbal, quantitative, and analytical abilities as measured by standardized tests. Results indicate a moderate correlation between search performance and academic performance and cognitive abilities and a stronger…

Development of two interactive videodisks in space science for middle-school-age children is described, and suggestions for development of affordable and successful interactive products are offered. The first interactive program is a touchscreen exhibit designed for museum use, and the second is a classroom tool for teaching a planetary sciences…

Discussion of the use of virtual reality in higher education looks at how this emerging computer-based technology can promote learning that engages all seven forms of intelligence proposed in H. Gardner's theory of multiple intelligences. Technical and conceptual issues in implementation of virtual reality in education are also examined.…

A theoretical description of hypertext is presented, and three applications of hypertext are discussed: electronic studying allows linkage of electronic note cards for writing and interrelating concepts; literary exploration allows construction and interpretation of stories with provided literary elements; in qualitative research, hypertext helps…

A project demonstrated the feasibility of accessing library information (online public access catalogs, commercial online databases, Internet) from a distance using handheld personal digital assistants (PDAs) equipped with cellular communication capability. The study is described, and other uses of wireless communications in libraries and…

An experiment applied the theories of knowledge engineering and expert systems to science instruction for junior high school students. The model encourages a more creative, constructivist approach to teaching certain science concepts and skills while fostering improvement of logical thinking, communication, and independent learning skills. Results…

A framework for examining the effectiveness of different types of educational computing environments addresses the conceptual characteristics of the knowledge domain being learned and the learner's stage of knowledge. Characteristics of certain technology-based learning environments (computer-based drill, intelligent tutoring systems, hypertext)…

A discussion of authoring system technology is based on a review of 80 products. Alternative authoring approaches are described; assumptions underlying development of authoring systems and their use are examined; selection procedures and criteria sensitive to varied needs are suggested; and trends in software development, evaluation, marketing,…

Access to online public access library catalogs and similar information networks by scholars in the humanities is discussed. Tools and approaches available for scholars to navigate the systems, their utility and contribution to "location independence" in information seeking, and the evolving relationship between libraries and their…
