The SMILI? (Student Models that Invite the Learner In) Open Learner Model Framework was created to provide a coherent picture of the many and diverse forms of Open Learner Models (OLMs). The aim was for SMILI? to provide researchers with a systematic way to describe, compare and critique OLMs. We expected it to highlight those areas where there…

The computer's potential for education, and most particularly for instruction, is contingent on the development of a class of instructional decision models (formal instructional strategies) that interact with the student through appropriate peripheral equipment (man-machine interfaces). Computer hardware and software by themselves should not be…

This survey elicited experts' perceptions of factors affecting development and use of interactive technologies. Responses from 196 respondents were categorized as hardware/technology, software/programs, acceptance/adoption, accessibility/ease of use, and instruction/learning/communication issues. Based on this categorization, a model of…

This paper focuses on graphics and how they can be created, in real time, from information stored in a database, and the application of this technique to computer-assisted instruction (CAI). It is noted that this is a special case of the general trend towards endowing instructional systems with a degree of decision-making or design expertise, as…

Model building techniques from Artifical Intelligence and Information-Processing Psychology are applied to human-computer interface tasks to evaluate existing interfaces and suggest new and better ones. The model is in the form of an augmented transition network (ATN) grammar which is built by applying grammar induction heuristics on a sequential…

Provides an example that illustrates the interrelationship of the factors that influence educational software portability. Nielsen's seven-level approach to human-computer interaction is used as the basis for a model for factors that influence portability, and five phases in the life cycle of a software product being adapted are considered. (10…

Designed for student use in solving linear programming problems, the interactive computer program described (EZLP) permits the student to input the linear programming model in exactly the same manner in which it would be written on paper. This report includes a brief review of the development of EZLP; narrative descriptions of program features,…

A computational framework is presented for the generation of elementary speech acts to establish conceptual alignment between a computer system and its user. This article clearly distinguishes between 2 phases of the alignment process: message interpretation and message generation. In the interpretation phase, presuppositions are extracted from…

A game that simulates stages in the innovation diffusion process and allows research into the spatial and temporal spread of innovations is reported. The characteristis of player decision-making and factors underlying variation in the spatial patterning of diffusion are also discussed.

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…

This paper describes and critically analyzes several perspectives on interaction and computer technology, examines dimensions of interactions, and presents a framework for the design of interaction strategies. Traditional perspectives on interaction discussed are the operational and the functional. The operational perspective is described in terms…

Describes the philosophy of intelligent instructional systems and presents an example of such a system, BLOCKS. The notion of BLOCKS as a paradigmatic system is explicated from both the system development and educational points of view. (Author/VT)

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…

Proposes a discourse analysis model of student-computer interaction, which, by viewing the student and the computer as two participants in a dialogue, provides the necessary elements and structures to describe computer-assisted language learning (CALL) discourse, analyze data from student-computer interaction, and compare CALL activities with…

Because of the lack of error-free, on-task performance by young children, cognitive modeling has not generally been considered an appropriate technique for characterizing computer use by young children. It is argued that cognitive modeling can be a useful strategy for organizing data on children's performance when the domain being studied is…
