Constructionist theory to explain effects of GDSS

This paper analyses communication between actors as a major theoretical ele ment in understanding the link between GDSS (Group Decision Support System) and the construction of shared meaning. The concept of shared meaning is d iscussed by using two schools of thought: Constructionism versus Constructi vism. The schools differ in their approach to processes of communication an d conversational techniques. Constructionist theory focuses on the necessit y to activate process of intersubjectivity between individuals to reach sha red meaning while constructivist theory focuses on process of negotiation. Arguments are given in this paper in favor of the Constructionist approach for dealing with the high complexity of the organizational issues involved in GDSS. The two theoretical approaches were operationalized under two diff erent paradigms of communication: Intersubjective (Constructionist) versus Negotiative (Constructivist) and were compared in an experimental set-up. B etter results were found for a GDSS based on the Constructionist paradigm.
