“…Educational models developed from a constructivist perspective (Duffy & Jonassen, 1992;Steffe & Gale, 1995) have reconceptualised the teaching/ learning process in terms of cognitive apprenticeship (Collins et al, 1989) and have proposed new directions for implementing learning environments, such as learning circles (Riel & Levin, 1990), communities of learners (Brown & Campione, 1990), and learning communities (Lin et al, 1995).
