I recently attended an figure drawing workshop where the instructor tried a few, very different experiments with the students. In light of our design challenge, her attitude toward experimentation struck me as exactly the way we should approach trying new things in our classrooms. To be specific: we tried drawing with 4 ft long sticks, drew the model while she was stuck inside a stretchy bag, and took turns acting as the teacher.
As an artist, herself, it was evident that she often experimented in her own creation process. She invited us to experiment with her, and made it exciting for everyone to see what would happen. There was no 'fear of failure,' because there was no specific goal, just...'hey, let's see what happens.'
I think that when we prototype, we will want to have more specific goals, things we want to test, but to approach our work with a lens of creative process could help us turn feeling fear to try of feeling excited to see what emerges.
