It is one thing to produce an innovative, construct-based assessment task; it's another to produce 10 a year that are comparable in difficulty, measure the same competencies, are free of differential item functioning, and can be scaled and equated. These challenges contributed to the failure of the performance (or authentic) assessment movement of…

Briefly discusses current views of the way anxiety decreases students' learning from instructional software and describes ways software designers might compensate for the learning problems of anxious students. (MBR)

Presents an approach to microcomputer courseware design that follows the engineering systems model and discusses areas of expertise needed by courseware designers, key courseware design questions, the accompanying teacher's guide and its components, and evaluation criteria teachers need to remember before purchasing instructional programs. (MBR)

Instructional projects are balanced when the pieces come together at one time with the concurrent approval of all interested parties. The physical analogy of a tripod can serve to illustrate the interaction among three dimensions of all projects: content, or what the course will contain; form, or what the course will look like; and process, or how…

Computer based instruction (CBI) is composed of individual frames viewed one at a time. Compared to a typical textbook, CBI restricts the adult learner's capacity to access information from different parts of the lesson and to view complex presentations. Designers of CBI must compensate for these limitations by making a concerted effort to…

Discusses the role of the graphic technologist in preparing computer screen displays for interactive videodisc systems, and suggests screen design guidelines. Topics discussed include the grid system; typography; visual factors research; color; course mobility through branching and software menus; and a model of course integration. (22 references)…

Describes research conducted at Lancaster University (United Kingdom) which investigated design considerations that were necessary for the development of effective interactive video (IV) courseware for management education. The advantages of a videotape-based system as opposed to videodisc are described, and technologies to minimize the drawbacks…

Describes the development of educational computer software called scenario software that was designed to incorporate advances in cognitive, affective, and physiological research. Instructional methods are outlined; the need to change from didactic methods to discovery learning is explained; and scenario software design features are discussed. (24…

Presents a methodology for the development of educational software for use in secondary education based on the characteristics of the students and the curricular objectives. Topics discussed include desirable features of educational software and the engineering of educational software, including its interdisciplinary nature. (Contains 10…

Color monitors are in wide use in computer systems. Thus, it is important to understand how to apply color effectively in computer assisted instruction (CAI) and computer based training (CBT). Color can enhance learning, but it does not automatically do so. Indiscriminate application of color can mislead a student and thereby even interfere with…

Discussion of speech recognition technology and its use in computer-assisted instruction focuses on prototype systems designed for medical education. Commercial speech recognition systems are described, hardware and software requirements are examined, and the use of a speech recognition system to streamline an existing user interface is discussed.…

Designed to address the management and use of computer software in education and training, this paper explores both good and poor software design, calling for improvements in the quality of educational software by attending to design considerations that are based on general principles of learning rather than specific educational objectives. This…

This article describes an approach to modifying science students' alternative conceptions of physical phenomena by means of diagnostic and remedial microcomputer programs designed in accord with a model of conceptual change. Current applications of microcomputers are discussed, including numerical work, drill and testing, tutorials, simulation,…

Outlines the design considerations that go into making an authoring system. Uses examples from the author's system, "Private Tutor," to illustrate. Emphasis is on the concepts that define the operation of the authoring system. Also discusses design principles of "Private Tutor" in relation to the Macintosh computer. (Author/LMO)

Computer assisted learning (CAL) is an old technology which has generated much new interest. Computers can: reduce data to a directly comprehensible form; reduce administration; communicate worldwide and exchange, store, and retrieve data; and teach. The computer's limitation is in its dependence on the user's ability and perceptive nature.…
