They conduct an extensive review of the present literature and examine Bates's interaction process analysis
(IPA), a common tool for collecting interactive data.
Bale's (1950) Interaction Process Analysis
(IPA) was adapted as the basis for content analysis to describe the patterns of student interaction in small groups through both synchronous and asynchronous networks.
Bales evolved a system of interaction process analysis
(IPA) that combined a structured set of categories for observation, and, a set of theoretical concepts underlying those categories.
The Bales Interaction Process Analysis
system is the best-known method employed for the study of small-group interaction.
