I am a highly structured and organized teacher, probably due to my background in special education (not my OCD tendencies, really). I work hard to personalize my learning and ensure that no matter ability level, students are given high (attainable) expectations. Structure does not mean there is not student driven learning, though! I find that the more clear and concise my rules and routines have become over the years, the more easily the learning can shift to student driven. We do a lot of differentiation in my room and a lot of stations and movement.
