In recent decades, deliberation about public issues has become a central theme in citizenship education. In line with an increasing philosophical and political appreciation of the importance of deliberation within democracy, schools, as training grounds for democratic citizenship, should foster high-level deliberative skills. However, when this insight is translated into practical formats, these formats suffer from a number of shortcomings. Specifically, they can be criticised on philosophical grounds for advantaging select societal groups, and on empirical grounds for facilitating groupthink mechanisms. This paper aims to address these shortcomings by suggesting a role for debating techniques within deliberative education. Because debating stimulates the contestation of diverse opinions, it may counteract the silencing of minority viewpoints and the proliferation of groupthink. At the same time, debating-based formats must be closely regulated in order to not imperil compromise formation. A concrete format is presented that balances these considerations and may therefore contribute to more effective deliberation in the classroom.
