The Hero's Journey

Generally people remember stories and much of children’s play involves taking on a persona. Conveniently, many courses involve multiple units, thus allowing multiple rounds of “play” and “identity” for students. The stories they make need to be thoughtful and challenging enough that students successfully complete the “Hero’s Journey,” with a healthy sense of being uplifted by the challenges encountered on the way. This is quite doable with a thoughtful implementation of an Agile Kickoff process. One of my favorite books on this subject is in the resources below.

Feedback: It's Not what You Think

Helpful feedback has little to do with what the teacher thinks, for example the pre-supposition the teacher makes about the outcomes of student projects, and is much more about developing an openness to what actually works and what others like, without an absolute truth either stated or implied by the curriculum. Let the students decide what to do by emphasizing these two types of feedback: - Natural feedback - Collaborative feedback

Reflection: The Key to Adaptability

Frequent, even daily, mini-reflections lead to adaptable students and curriculums. Ideally, guide the students to where they are comfortable to self-reflect with you. This of course means guiding the kids to where they have the confidence and insight to self-reflect and self-correct instead of relying (or even fearing) external assessment and correction.
