We first spoke about creativity and how it can be learned and practiced. Also about the importance of process as opposed to results, and we used the example of how small children play spontaneously.
Our 3-D collage consisted in playing a game where students were invited to look for objects, photographs, paintings, images, games, clothing, anything that could express something about themselves, their tastes, worldview, anything special for them or something that, for any reason, stood out at that time. The idea is for them to grab whatever calls their attention first, without thinking, emphasizing that there are no mistakes in this game.
The procedure calls for them to arrange their selected objects on top of the table in whatever way they want. The initial layout is the definitive one. They then take a photograph, and share something about their creation and why it represents them.
