Prototyping may be the most powerful form of scaffolding. Prototyping elevates students' sense of agency and it allows students to see the progress of their quality of work. The art of prototyping and revisions are refined by critique and self-reflection. Kind, specific, and helpful. KiSH was a protocol that we often used in the classroom and in the professional learning space. A protocol like this guides students to engage and make the act of critique meaningful. Note that this critique only works when students are given a chance to make multiple revisions. Conditions matter.
