Abstract :
This paper presents a theoretical framework for viewing elements that
comprise distance education instructional systems in terms of dialogue. It is
assumed that learning is mediated by intrapersonal dialogue and facilitated by
interpersonal dialogue. Every resource in a distance education instructional
system (eg, instructor availability, asynchronous communication networks,
self-instruction texts, etc) is analysed in terms of the dialogue mode it supports.
The framework offers three advantages: (1) a unified, simple, and coherent
description of the mechanisms at play in distance education systems, (2) clearcut
operational definitions, and (3) hypotheses that may be investigated
empirically.
