One of the terms we use in teacher education is "unlearning." What we mean by that is creating space for teacher candidates to unlearn what they thought they knew about teaching based on their experiences as students, or through what they thought teaching actually is. In other words, to question what they think is true about students, the profession, and teachers.
For example, when I started teaching at Aurora Alternative High School, I was appalled that some of my students would want to attend the local community college (never mind not go to college at all), as opposed to a state college. I had to unlearn my assumptions that everybody who was going to be anybody in life was either a) a natural genius and didn't need to go to college or b) would go to a four year college.
What my students taught me--what I "unlearned"--is that "smart" looks different according to context. I unlearned seeing my pregnant students as victims. I unlearned that all graffiti was trashy. I unlearned that smart meant being good at school.
Teacher research is all about unlearning: about questioning our assumptions and taking risks. It is NOT about proving a particular hypothesis. So what assumptions have you questioned about your students, teaching, or yourself during this process? What new truths have you uncovered?
