The French word vertnissage is used to describe a preview of an art exhibition. When facilitating work done in smaller groups, Instead of having each of them present their results, have each group post their work. Have participants visit the work of other teams. Each participant has three possible ways of commenting silently on the work of his/her colleagues:
Writing/sticking a heart shape to show agreement with any point and adding a comment which builds on that point
Writing/sticking a ‘lightning’ flash to indicate disagreement with any point and adding a reason for disagreement
Writing/sticking a question mark to say ‘I don’t understand this point’ You, as a facilitator, then lead the final discussion to clarify all the vernissage hearts, flashes and question marks.
