There is an urgent call for science and STEM teachers to incorporate practices for equity-centered environments, social justice-orientations, criticality and other practices that promote system change. Yet this demand occurs against the backdrop marginalization of teachers' from having a say in the planning, teaching, and assessments in their own classrooms as teachers are stripped of agency, authority, and autonomy. We argue that these two simultaneous trends in science and STEM education--the drive for equity-centered environments and the systemic devaluation of teachers' expertise--are incompatible. Realizing the goal of science classrooms that support equity-centered and social justice-oriented learning requires that teachers have equal voice in important decisions on matters that impact their day-to-day actions, which includes the power to determine goals and practices. This means dismantling some of the power structures in the educational system that disenfranchise teachers' from making decisions based on their own knowledge, and their own goals for learning, particularly goals for social-justice and equity. In this article we describe pedagogical frameworks for making transformational change in science classrooms and in wider society and show how each framework is dependent on equity for teachers. We end with implications for this shift--moving toward a system where teachers have equal power--that is an essential part of creating science classrooms as sites of equity, social justice and science learning.
