I adopted Leonardo da Vinci’s 7 Principles as a guide and was especially attracted to Sfumato, usually translated as “Up in Smoke,” meaning to embrace ambiguity, paradox and uncertainty. Great things are produced and discovered when you open the door to possibilities and leave some things undefined. When I did that, there was difficulty adjusting as kids had been trained to give the right answers. My response was there may be none and that I was more interested in originality, creativity, and being able to explain and defend one’s thinking. En Garde!
However, once kids realized that they were full partners in their learning and that most anything was possible, they brought me to tears with their work.
