The Challenge: You have to teach a concept, but you have no working knowledge of examples of that concept in the work lives of the participants.
Possible Approaches: Conduct a preliminary needs assessment when you have the participants introduce themselves, checking for their previous experience and expertise.
Explain the concept using a common example from daily life (family, food, nature-related). Then draw from the group two or three additional real work examples that are relevant to their experience. This will ensure that at least three examples are provided to make learning successful.
You can also have small groups or individuals apply the concept to their specific situations and describe its application in their work lives.
