This paper introduces a new pedagogic approach to the teaching of political science. In engineering education, the Conceive-Design-Implement-Operate (CDIO) pedagogy provides an active, experiential learning experience, structuring learning around four key phases in product development. Applied to the undergraduate Politics and International Relations (IR) classroom, this pedagogical innovation in learning, teaching and assessment is adapted to policy development. This design-build-test pedagogical approach has been highly successful in engineering education, supporting students to be "industry-ready engineers" on graduation. Results across 3 cohorts suggest that this pedagogical innovation is also highly successful when transferred to Politics and IR, supporting political science students develop "society-ready" attitudes, attributes and skills, greatly enhancing the student experience and increasing their attainment, engagement, inclusion and wider graduate outcomes. Civic engagement and the ability to understand and respond to a range of stakeholders are also improved. This paper presents the pedagogy and the module to which it was applied as a case study, before highlighting opportunities for political science educators to transfer the pedagogy to their own teaching context.
