Stop and think about the most significant lessons you've learned in life - times when you've gained insights or skills of lasting importance. Now reflect for a moment - did this take place in a classroom? were you taught these lessons by a teacher? did the teacher evaluate how well you learned them?
Tara, I think this would be a great tool for you to use with your students.
Recently my Twitter network (thanks @L_Hilt ) pointed me to an insightful observation on the traditional classroom. Next time you lament that students aren't motivated, think about the distance between what we learn in school and what we learn in life.
