The purpose of this study was to investigate how adult students learn collaboratively with other peers in both formal and non-formal adult literacy programs and what teaching styles best support this learning. A multi-site case study research design was used involving several different literacy organizations in Eastern Ontario, Canada, and in Central London, United Kingdom. Findings suggest that collaborative learning is the cement that bonds the various building blocks in a community of literacy practice across small, large and tutorial types of programs. Central in this framework is the component called the Instructor’s Philosophy and Teaching Perspective which helps explain the teaching and learning transactions.
