Curiosity is increasingly recognized as a core intellectual virtue that supports adaptive problem-solving, ethical discernment, and innovation in professional engineering practice. Yet in undergraduate education, curiosity is often treated as a happy byproduct of instructional design rather than a deliberate target of professional formation. This mixed-methods article addresses the critical gap between conceptual theory and prescriptive pedagogy. We first synthesize 63 peer-reviewed articles to confirm how curiosity is defined, measured, and cultivated, using psychological models to differentiate curiosity as a momentary reaction versus a motivational drive and durable character trait. Our scoping review confirms that current engineering interventions are overwhelmingly short-term and typically promote fleeting, passive engagement through inquiry-based activities, rarely addressing the necessary development of active, sustained curiosity or its crucial relationship to adjacent virtues like intellectual humility. To address the pedagogical gap, we report on semi-structured interviews with engineering faculty to uncover the implicit strategies, or "levers," they use to promote curiosity in their classrooms. This work offers two key contributions designed for the broader ASEE audience: a pedagogical strategy for cultivating active and sustained curiosity in the engineering classroom, and a set of validated metrics, adapted from longitudinal studies, to assess the efficacy of these levers. By shifting the focus from accidental "spark" to deliberate, measurable "cultivation," this framework lays the groundwork for integrating curiosity as an essential professional competency.
