This paper crane art installation was made by over one hundred year 5 and 6 students, using a 'cascade learning' technique. Initially a small group of students were taught how to make paper cranes. They then went away and taught another student, and this continued until all the students knew how to make paper cranes. The cascade technique meant that instead of just having one expert (the teacher) having to teach the skill to everyone, the kids became the experts and were teaching each other.
I love the idea of this technique! Obviously it lends itself to older grades and wouldn't work with all lessons, but there are lessons where this technique would work so well. We know that one of the best ways to learn something is to teach it to someone else, and I love how this is such a practical example of that!
