In my classroom I have instituted these questions as the daily "Kick Off Question". When students come into the classroom their is one of the questions on the screen, they write the question, and their answer. While the students are working I walk around to glance at answers. This gives me a chance to make note of anything that needs immediate attention on my party. At the end of every two weeks the students will turn in their questions and as a result I have a record of information that can help me help my students.
As teachers we need to help students be reflective and learn more about the way they think and what motivates them- sometimes they have to figure themselves out before their voice can be a true reflection of what they need.
