This digest discusses types of computer applications used in science assessment; underlying assumptions that guide their roles in assessment; and issues which relate to validity, gender equity, instructional delivery, mode of user interface, and responsibility to the public. Assessment applications for computers can be broadly classified into two…

This digest discusses the nature of interactive videodiscs and their educational applications, provides information about educational uses of videodisc technology, and presents lists of videodisc-related organizations, books, and periodicals. A general description of a reflective optical laser videodisc is presented, as well as the equipment…

Virtual Reality (VR) is a computer-created sensory experience that allows a participant to believe and barely distinguish a "virtual" experience from a real one using computer graphics, sounds, and images to reproduce electronic versions of real-life situations. This digest describes how VR works and discusses applications of VR in…

Interactive videodisc (IVD) offers a combination of media with practical applications in vocational education. IVD is superior to videotapes and other media in quality, applicability, and effectiveness. IVD can be used in different settings and for a variety of instructional applications. Although not appropriate for every learning situation, IVD…

This digest contains four sections that discuss the following broad principles that offer a framework to teachers for thinking about how technology can support their instruction: (1) learning occurs in context, including ways that technology can facilitate learning by providing real world contexts that engage learners in solving complex problems,…

This ERIC Digest presents a brief description of some applications and findings of the microcomputer in science classrooms. It is suggested that microcomputer simulations are at least as effective as hands-on experiences for some cognitive outcomes and may in fact enhance these outcomes when the simulations are sequenced to follow hands-on…

This digest focuses on going beyond multiple choice testing to the development of methods for assessing complex knowledge and performances. Newly designed assessment systems must accurately measure and promote the complex thinking and learning goals that are known to be critical to students' academic success and their eventual sustained…
