Abstract: | This study investigates the mechanisms of scaffolding in a synchronous network-based environment – the ‘collaborative virtual
workplace’. A theoretical ‘multi-actor’ scaffolding model was formulated. The study itself focused on the role and inter-relations
of verbal scaffolding by tutor and peers during a collaborative process of making decisions about environmental issues. The analysis drew on data from the decision-making
discussions of 31 groups – material that was saved automatically by the learning environment software. The age of the 62 students
ranged from 14 to 17. Discourse act categories were devised to describe the tutor’s and the students’ task-related, supportive
and social communicative acts. The scaffolding situation was characterized through a causal discourse act interaction approach.
Tutor and students appeared to be elaborating and replacing each other’s process scaffolding acts in the collaborative decision-making
situation. The influence of certain tutor’s and students’ inter-related scaffolding patterns on students’ decision-making
provided empirical support for the ‘multi-actor’ scaffolding model.
