This discussion of the design of computerized psychological assessment or testing instruments stresses the importance of the well-designed computer-user interface. The principles underlying the three main functional elements of computer-user dialogue--data entry, data display, and sequential control--are discussed, and basic guidelines derived…

An overview of the research and design process that led to the creation of the Bank Street word processing program for children is reported. The decision to create a word processor for the classroom was based on the findings that commercially available programs took too long to learn, required the memorization of too many commands or rules, had…

Educational games are usually developed by copying existing recreational games and adding instructional components, or by using the intuitive preferences of the designer. However, existing games attract people through ideological value exemplifications. Moreover, whatever else they teach, games teach ideologies of either preservation, equality, or…

Emphasizing more effective use of existing equipment, this article highlights distributed computing design considerations applicable to educational environments; identifies potential roles of networking in the provision of adequate teaching aids; presents a networking model; and describes the development of a distributed computing configuration at…

Reviews the literature pertaining to the design of the layout of computer text screens as a means of maximizing comprehension in computer-assisted learning. The literature on the design of instructional text is also examined to extrapolate principles that may apply to screen design. (Author/LRW)

The objective of the unified database (UDB) program was to develop an automated information system that would be useful in the design, development, testing, and support of new Air Force aircraft weapon systems. Primary emphasis was on the development of: (1) a historical logistics data repository system to provide convenient and timely access to…

Because of the need for models to illustrate some possible answers to practical courseware development questions, a specific, three-section model incorporating the Corrective Feedback Paradigm (PCP) is advanced for applying theory to courseware. The model is reconstructed feature-by-feature against a framework of a hypothetical, one-to-one,…

Pointing out that interactive video (IAV) represents a synthesis of four primary technologies--computers, television, visual design, and instructional design--this paper discusses the what, why, and how of IAV visuals. The features and relevant aspects of each technology are briefly discussed, as well as the impact of each of these technologies…

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…

The content and quality of the documentation and teachers guides that accompanied 55 educational microcomputer software programs were examined, to determine whether the technical and pedagogical information provided by such guides enabled teachers to fully exploit the instructional potential of the programs. The courseware covered basic elementary…

In early computer assisted instruction (CAI), negative feedback often insulted students and/or provided no useful knowledge. In classroom settings, teachers use the following approaches in dealing with students' wrong answers: (1) ask the question again, louder and slower; (2) ask the question again, using different words; (3) back up and reteach…

Identifies human factor issues involved in the student-computer interface in computer assisted instruction and makes specific recommendations for screen design. Factors considered include simplicity, spaciousness, relevance, standardization, changing display screen contents, color coding, shape and size coding, and brightness coding. (Author/LRW)

Presents a formal model for specification of logical requirements of computer-based information systems that incorporates structural and dynamic aspects based on two separate models: the Logical Information Processing Structure and the Logical Information Processing Network. The model's role in systems development is discussed. (MBR)

In this article, the author discusses his list of seven precepts for good research in leadership in education. These precepts are: (1) The need to be clear about what research is; (2) The need to have regard to the applied nature of the field; (3) The need to differentiate but not to balkanise; (4) The need to be comprehensive and inclusive; (5)…

This paper argues that an important design principle for building expert systems is to represent all control knowledge abstractly and separately from the domain knowledge upon which it operates. Abstract control knowledge is defined as the specifications of when and how a program is to carry out its operations, such as pursuing a goal, focusing,…
