This desgn uses a wiki to involve students in exploration of a theory, reflect on how it might impact on their current practice, and to analyse others' ideas on the same topic using a process of peer assessment. It could be used in applied disciplines e.g. business/management, or health and social care. This is a prototype of a design, i.e. the design is not fully developed. It is intended as a prompt for others to build on and make specific to their needs. The example includes a link to a web site about activity theory as an exemplar, but this example should be replaced by one or more appropriate resources by the teacher using the design.
