Professional development has been broken for decades - and will continue to be broken until we disrupt the institutional norms that erode teacher agency. I'm inviting all of us - classroom teachers and those who support their learning - to embark on a journey to create the teacher-centered culture of professional learning we need to thrive as imperfect and unfinished teachers. It's time that we learn how to direct our own professional growth, individually and collectively, so we can seize control of our teaching legacy and the math stories we leave behind in this world.
