Bright Shadow uses themes because they bring fun and a sense of occasion to the workshop. A theme gives meaning to individual activities and to the workshop as a whole. By using a theme, what might seem like a meaningless collection of activities becomes purposeful because they are all contributing to the sense of going on a journey somewhere together, which in turn brings a sense of achievement. This approach also helps people to cognitively engage in activities. The theme serves as a ‘scaffold’ for the activities to be built onto.
