Service learning presents students and teachers alike with emotionally fraught moments. Before these moments shape ideologies and worldviews, they give us sensations. Understanding these sensations is part of what theorists label the affective domain. Affect is a notion garnering much critical attention from compositionists writ large but little attention in the service learning literature. The field has much to gain from acknowledging that students and teachers both experience civic engagement rationally as well as affectively. One of the potential benefits is a more sensitive understanding of how various modes of civic engagement (e.g., volunteerism and activism) are socially, ideologically, and emotionally constructed.
