Theory Name: Random Access Instruction


Authors (Last, First): Spiro, Rand J.; Feltovich, Paul J.; Jacobson, Michael J.; & Coulson, Richard L.

Associate Learning Theory:
Cognitive constructivist learning: based on Cognitive Flexibility Theory focusing on the nature of learning in complex and ill-structured domains. By cognitive flexibility, one is able “to spontaneously restructure one's knowledge, in many ways, in adaptive response to radically changing situational demands...This is a function of both the way knowledge is represented (e.g., along multiple rather single conceptual dimensions) and the processes that operate on those mental representations (e.g., processes of schema assembly rather than intact schema retrieval).” (Spiro & Jehng, 1990, p. 165)

Model Description:
The central claim of Cognitive Flexibility Theory is that revisiting the same material, at different times, in rearranged contexts, for different purposes, and from different conceptual perspectives is essential for attaining the goals of advanced knowledge acquisition (mastery of complexity in understanding and preparation for transfer). Thus, instructional emphasis is placed upon the presentation of information from multiple perspectives and use of many case studies that present diverse examples. The theory advocates the properties of hypertext systems which facilitate flexible restructuring of instructional presentation sequences, multiple data codings, and multiple linkages among content elements.

Specification of Theory
(a) Goals and preconditions
To provide flexible instruction appropriate for developing cognitive flexibility.

(b) Principles
1) Learning activities must provide multiple representations of content.
2) Instructional materials should avoid oversimplifying the content domain and support context-dependent knowledge.
3) Instruction should be case-based and emphasize knowledge construction, not transmission of information.
4) Knowledge sources should be highly interconnected rather than compartmentalized.

(c) Condition of learning
Hypertext environments for promoting cognitive flexibility in ill-structured domains.

(d) Required media
Interactive technology media such as videodisc and hypertext

(e) Role of facilitator
To provide multiple representations of situated content knowledge

(f) Instructional strategies
1) Provide multiple approaches that range from multiple organizational schemes for presenting subject matter to multiple representations of knowledge
2) Rearrangement of the presentation sequence of content in order to produce different understandings when that content is “re-read”: Provide students with the option of reading an expert commentary on the special shade of meaning associated with the conceptual theme after the scene is viewed.
3) Provide cross-references as commentaries

(g) Assessment method
Assess case-based knowledge construction

Formative Research & Application
(a) Tested context: K-12 (Sprio & Jehng, 1990)
(b) Research method
(c) Research description
: KANE (Sprio & Jehng, 1990) is a learning environment in which students are given literary texts supporting multiple interpretations. The Cognitive Flexibility Hypertexts provide generic conceptual structure particularized to specific cases and optional background information on the contexts immediately preceding the one being explored.
