No two class sections are identical. Each classroom, building, and school district is different because teachers and students are individuals. Wide variation in background knowledge and lived experience is what makes teaching a profession. Educators must respond to the needs of their learners, but they can only be responsive if they have the autonomy to make independent choices that affect their classrooms. As educational leaders promote professional growth and systemic change they must avoid undermining the autonomy of the teachers they lead. Autonomous Practice The Kansas School Redesign is one of many reform efforts initiated in the globalized educational landscape (Y. Wang, 2013; Zajda, 2005). State leadership and reformers are seeking to explore new ways of teaching in order to identify educational best practices they can promote broadly across the state. While policymakers exert their influence to improve student outcomes for Kansas, they must continue to value collaborative autonomy as a centerpiece of their dissemination efforts. We define "autonomy" to be an educator's authority to make choices about how they engage in their practice on a day-today basis. "Collaborative autonomy" is then the ability to work with other professionals in planning for and reflecting on their choices, while still retaining their ability to independently make future decisions. The goal of educators is to grow our students. We seek to improve what they know, what they can do, and who they are as people. When students have the opportunity to exercise autonomy, they achieve growth in many educational metrics. Primary students with autonomy in their class demonstrated better motivation, enjoyment, and effort than those without (Leptokaridou, Vlachopoulos, and Papaioannou, 2016; Skinner and Belmont, 1993). College-age students saw similar benefits from increases in autonomy (Jang, Reeve, and Halusic, 2016). Positive effects were observed in science (Black and Deci, 2000), mathematics (Stipek et al., 1998) and foreign language (Benson, 2007). Student growth extends into the citizenship characteristics required by the Kansas redesign efforts by promoting open-mindedness and justice (Taylor, 2017). Autonomy improves the outcomes of students while also improving the experience of faculty and administration. Teachers, at all levels, who are provided autonomy, in both general operation and in curricular planning, experience decreased on-the-job stress and increased empowerment and professionalism (Collie, Shapka, and Perry, 2012; Pearson and Moomaw, 2005). Stress in teachers is linked to stress in students (Oberle and Schonert-Reichl, 2016). Teachers who report experiencing low autonomy at work are similarly unlikely to support the autonomy of their students (Marshik, Ashton, and Algina, 2017). Science teachers also derive benefits specific to their discipline. The recently adopted Next Generation Science Standards call for students to engage in scientific inquiry and practice, and professional development efforts must support teachers a...
