User Interface Improvements in Computer-Assisted Instruction, the Challenge.

Abstract The purpose of this paper is threefold: (1) to identify user interface problems as they relate to computer-assisted instruction (CAI); (2) to review the learning theories and instructional theories related to CAI user interface; and (3) to present potential CAI user interface improvements for research and development based on learning and instruction theory. User interface is defined as “hardware, software (including menus, screen design, keyboard commands, and command language), or both that allows a user to interact with and perform operations on a system, program, or device” ( McDaniel, 1994 , IBM dictionary of computing (10th ed.). New York: McGraw-Hill, p. 724). Not all learning theories and instructional theories are discussed, but those most influential to CAI are included. Likewise, not all potential CAI user interface improvements are addressed but, rather, the focus is on CAI screen design user interface improvements. Proposed improvements are those which could be easily researched and incorporated into CAI design.
