or with assistance from group peers, the teacher can ‘take over’ by once again modelling theappropriate approach, often out loud, in a protocol analysis environment, for all students.Gradually, students are required to complete tasks more independently, with the final classassessment item requiring the development of a complete model of a problem, with critiqueand justification of the approach taken, with minimal support from the teacher.Table 6.1: Phases of Cognitive Apprenticeship model as implemented in ENG260Phase Component Class Activities & Teacher RoleSessionsI Modelling 1-6 Demonstration of a task as a process.

It should be noted that there is no clean256
