MediaMatrix: An authoring system for adaptive hypermedia teaching — Learning resource libraries

Abstract

A NEW adaptive computerized instruction authoring system, calledMediaMatrix, requires that content developers adhere to a wide variety of learning principles as they aspire to accomplish outcome learning goals which include not only the acquisition of specific content, but also the development of general comprehension and problem solving skills. This authoring system was designed for development of final products which include those referred to as Hypermedia Teaching-Learning Resource Libraries. These libraries are conceived as being not only a replacement for such traditional teaching resources as transparencies, notes, videos, laboratory exercises, and tests; they also are envisioned as replacing such student resources as the traditional textbook, study guides, and human tutors. By incorporating several artificial intelligence engines and knowledge generation systems,MediaMatrix enables developers to build adaptive programmed instruction and adaptive testing systems with comparative ease. This authoring environment allows developers to focus simultaneously on the systematic improvement of comprehension and problem solving skills while also providing for adaptive content presentations that change delivery rates to accommodate varying rates of learning. As students learn new material, the system not only learns what they know, but also the rate at which they are learning it. It then adapts instructional content delivery and testing to best meet the need of learners.
