One of the first techniques Doug Lemov introduces in his collection of classroom methods is the principle of No Opt Out - the notion that students don’t get to choose whether or not to participate, or indeed whether or not to succeed. It is interesting to consider, both because of the way it typifies his approach of finding practical ways to structure classroom interactions so as to embody a fundamental set of values, and therefore also as a case study for adaptation to the choral rehearsal. The specific form(s) of the interaction will change, but we can still find concrete, actionable steps to embody the principle.
So, the way this plays out in the classroom is as follows. The teacher asks a student a question. If they answer correctly, fine, carry on. If they struggle to answer, or try to slide out of trying to answer by saying ‘I don’t know’, the teacher finds a way to help them out of the impasse, but makes sure the interaction ends up with the student stating the right answer.
