Explores the concept of "theater of the mind" and discusses design factors in creating audio works that effectively stimulate mental pictures, including: narrative format in audio scripting; qualities of voice; use of concrete language; music; noise versus silence; and the creation of the illusion of space using monaural, stereophonic,…

Two experiments explored the nature of perceptual development in 5- and 10-year olds and adults. The primary finding was that preassessed salience significantly influenced 5-year olds' ability to discriminate two objects, while salience did not affect 10-year olds' or adults' response times. Results showed that salience effects in perceptual…

The project DEVISE case study shows how diversity modeling can be used as a powerful design tool. Designers used performance-centered design techniques to create a virtual learning environment in which students with learning disabilities would be more fully supported with an interface that meets their needs.

This article proposes and tests a formal cognitive model for the go/no-go discrimination task. In this task, the performer chooses whether to respond to stimuli and receives rewards for responding to certain stimuli and punishments for responding to others. Three cognitive models were evaluated on the basis of data from a longitudinal study…

A good instructional game, like many good commercial games, should be built around what the author calls "authentic professionalism." In such games, skills, knowledge, and values are distributed between the virtual characters and the real-world player in a way that allows the player to experience first-hand how members of that profession think,…

This article asks how good video and computer game designers manage to get new players to learn long, complex and difficult games. The short answer is that designers of good games have hit on excellent methods for getting people to learn and to enjoy learning. The longer answer is more complex. Integral to this answer are the good principles of…

In an effort to individualize instruction and improve the effectiveness of instructor-learner transactions, education and instructional research has addressed a wide assortment of learner variables and assessed their relationships to instructional methods and environments.

Abnormalities of colour perception in children with autistic spectrum disorders have been widely reported anecdotally. However, there is little empirical data linking difficulties in colour perception with academic achievement. The Wilkins Rate of Reading Test was administered with and without "Intuitive Coloured Overlays" to 19 children with…

Despite the fact that students are an important component of the educational process, their preferences for instruction are not typically a consideration for classroom practices. The purpose of this survey study was to determine high school students' preferences for methods used in the instruction of literary works of art. Students expressed…

The most common use of computers in distance education is in the preparation of a visual image that is somehow transmitted to students. This paper addresses some design considerations for computer-produced visual displays that are intended for either local or distant audiences.
