A friend of mine, Clifford Weber, Superintendent in Bloomfield, New Mexico does something similar. He has three questions he asks of students and says that "The answers tell you a lot about students' experiences in schools."
- "What are you doing?"
- "How are you doing with it?"
- "Why are you doing it?"
While in Bloomfield he worked with the staff to turn these questions into opportunity for student reflection and self-assessment during lessons. Teachers also asked "What do you already know about a [a topic]?" and "When are you going to use it?" The questions became a routine part of class and helped students connect their current lesson with past learning and future application.
I'd be interested in hearing from you about what you look for when observing in classrooms and how your teachers provide opportunities for students to reflect on their learning.
