This paper follows recent debates around theorizations of "affect" and its distinction from "emotion" in the context of non-representational theories (NRT) to exemplify how the ontologization of affects creates important openings of ethical and political potential in educators' efforts to make productive interventions in pedagogical spaces. The ontological orientation provided by NRT has two important implications for educational theory and practice. First, it exposes the indeterminacy and inventiveness of affective capacities of bodies, illustrating how diverse socio-materials events are variously enrolled in everyday school life processes of differentiation. Second, it emphasizes an affirmative account of the ethics and politics of affect in which connections and relations forged between bodies, things and spaces constitute the basis of new configurations of affects and emotions in schools.
