This activity allows the teacher to gather the representations of a group in order to construct a common definition of a concept before approaching or building a content. The principle is to put in place a framework facilitating the negotiation around the definition exercise.
Example : The teacher displays the concept of the intervention and asks each one to write down a list of 6 words evoked to him by this concept. It leaves 2 minutes for everyone to create their list. Then he asks everyone to turn to his neighbor to create with him a single list of 6 words from their two lists. Always in 2 min. Then he asks the duets to get closer to another duet to create a common list from their two lists. They have 3 minutes to do it. Depending on the size of the group you can still proceed in the same way to have 1 list for 8 people. The step will last 3 min too The idea is to have 2 or 3 groups each with a list of 6 words, negotiated along these "meetings". From these lists, each of the 2 or 3 groups negotiate to design their own sentence containing each of the 6 words of their own list. The sentences are exposed to the full group that decides which fits best to the definition that the whole group will adopt. The teacher at this stage may serve as moderator, and if necessary can arbitrate in favor of one of the definitions, or none, or at worst, in favor of a composite definition made from the definitions of small groups.
