I would truly allow each student to be an individual. To allow students to guide, not only their learning, but as well as their assessment. Students will no longer be "passengers on a fast bus down a lone highway" but instead "participants on a field trip to a field of their choosing" . Top down mandated policies focused on increasing test scores would be replaced with guidelines, created by and with teachers, to allow for deeper learning. Teacher PD will always be encouraged as the work teachers do outside of school is just as important as the work they do inside the school.
Outcomes will no longer be delivered in the hundreds, where each is extremely specific, but come in few general outcomes. This will allow for teacher autonomy in classes and allow for learning to be focused around the needs, wants, aspirations, and goals of each student instead of the goals of the system.
Technology, with unfilitered access, will be used in classrooms to create engagement around learning instead of being implemented to trick students in completing mundane tasks. The goals of each class will be around meaningful questions instead of repeptive answers.
Teaching will be around one single absolute goal; lighting fires of interest and curiosity in each student of the school.
