Presents an engineering environment oriented to the development of hypermedia applications for training. Training trends are described; requirements for a computer-based training (CBT) strategy are outlined; a hypermedia course structure is examined; microinstructional events (MIEs) are explained; and technology requirements and selection are…

RESGEN is a computer program designed to generate simulated latent trait distributions and then dichotomous or polytomous item responses based on item response models. The latent trait distributions can be univariate or multivariate normal, log-normal, uniform, or gamma. The item response models utilized in this program may have characteristics…

This paper identifies three ways that computers are used in educational contexts. The first and most widespread use is as a tutor, i.e., as a delivery system for programmed instruction and drill-and-practice activities. The second use is as a programming environment to teach programming languages such as BASIC, LOGO, or PASCAL. The third use is as…

Describes two systems that incorporate tutoring elements into pre-existing software packages: one supporting Geometer's Sketchpad and the other Microsoft Excel. An analysis of their similarities and differences provides a foundation for standardizing the components of learning environments, simplifying their creation and increasing the power of…

Discusses hypertext and describes three abstract models that represent different levels in the design-decision process necessary for effective hypertext development. The use of information management software is discussed; combining hypertext and information retrieval models is considered; and opportunities for hypertext are described, including…

A new paradigm is proposed for thinking about educational software, based on a the mutual interaction of the perspectives of those concerned in the use of educational software: the student, the teacher, and the software designer. This rejects the usual checklist approach and leads instead to an approach to software selection closely associated…

Describes LISPA (Library and Information Center Staff Planning Advisor), a set of programs based on Ranganathan's staff plan model. LISPA particularly aids in planning for library staff requirements, both professional and paraprofessional, in developing countries where automated systems for other library operations are not yet available.…

Claims that the development process for computer software can be greatly aided by the writers of specifications if they employ basic iteration and prototyping techniques. Asserts that computer software configuration management practices provide ready models for iteration and prototyping. (HB)

This paper investigates, through a case study, the development of a software architecture that is compatible with a system's high-level requirements. The case study is an example of an extended customer/supplier relationship (post-point of sale support) involved in e-universities and is representative of a class of enterprise without current…

Discusses the role of intelligent agents in facilitating the seeking and retrieval of information in Web-based library environments. Highlights include an overview of agents; current applications in library domains; an agent-based model for libraries; the design of interface agents; and implications for library policy and digital collections.…

Presents a layered architecture for hypermedia systems that uses the MHEG (Multimedia and Hypermedia Information Coding Expert Group) proposal to provide the desired independence between hypermedia applications' conceptual models and storage strategies for hypermedia objects. An overview of the MHEG standard proposal is provided. (Contains 16…

This paper describes the creation and evaluation of a World Wide Web-based courseware module, using conceptual models based on constructivism, that teaches novices how to use the Internet for searching. Questionnaires and interviews were used to understand the difficulties of a group of novices. The conceptual model of the experts for the task was…

Examines factors affecting selection and development of computer simulations, including type of learner, simulation formats, instructional purposes, learning outcomes, fidelity, learning stages, and logistical issues. A flowchart model and set of prescriptions to help designers arrive at specifications for an instructional simulation are…

Presents a conceptual framework for building an intelligent documentation system (IDS) for computer software by integrating hypermedia and expert systems technologies. The need for online computer documentation for end-users is discussed, and elements of the synergetic model are described, including knowledge representation, the hypermedia…

Reviews strengths and weaknesses of check lists for the evaluation of computer software and outlines consequences for their practical application. Suggests an approach based on an instructional design model and a comprehensive framework to cope with problems of validity and predictive power of software evaluation. Discusses prospects of the…
