This is the fourth and final installment in a series of articles presenting a new outlook on the methods of instructional design. These articles examine the nature of the process of instructional design and are meant to stimulate discussion about the roles of designers in the fields of instructional design, the learning sciences, and interaction…

Provides a structural definition of interactivity in instruction, with the goal of describing and delimiting a broad and general process. Examines the four major attributes to the concept of interactivity, and defines four additional variables that arise through the structural study of interaction. Outlines five common patterns that deal with…

Discussion of intelligent tutoring systems highlights various instructional models which emphasize experiential interactions. Topics discussed include computer assisted instruction; instructional strategies; the TICCIT system; branching; the Socratic method; definitions of tutoring and instruction; students' interactions with the computer; advisor…

Examines the functional characteristics of intelligent computer assisted instruction (ICAI) and discusses the requirements of a multidisciplinary cooperative effort of its development. A typical ICAI model is presented and intelligent features of ICAI systems are described, including modeling the student's learning process, qualitative decision…

A plan for a demonstration school is outlined. The design calls for a reallocation of capital and labor resulting in the heavy use of instructional technology and differentiated staffing. Comparisons with traditional schooling show the model to be potentially more cost-effective. (BD)

Describes the Hypertutor Model, a message design framework for interactive instructional systems that emphasizes learner control, presentation, practice, feedback, and learning resources. Problems with software designed for computer assisted instruction are examined; hypertutor systems are discussed; and MegaMentor, a hypertutor system at the…

Discussion of courseware evaluation for computer-based training (CBT) highlights the CITAR Computer Courseware Evaluation Model (CCEM), which was developed at the Center for Interactive Technology, Applications, and Research (CITAR) at the University of South Florida. Instructional and interactive characteristics of commercially available CBT…

Describes virtual personal computing, a computer-based educational infrastructure for all students from kindergarten through college, as a step toward meeting national educational goals. New technologies that make this concept possible are described, including the Asymmetric Digital Subscriber Line (ADSL); and the theoretical basis of the virtual…

Discussion of the impact of computers on education highlights the role that educational technologists can play as change agents. Topics discussed include models of the diffusion and adoption of innovations; computer interfaces; integrated software; teacher training; teachers' roles; and the use of magnet schools to demonstrate the effectiveness of…
