Based on the data collected from focus groups and individual interviews with secondary school students and civic education teachers, this article explores how young people are transformed to become active and participatory citizens. The findings show that the roles and personal beliefs of civic education teachers are of critical significance at the very first stage whereas their teaching methods help enable students to construct the notion of active and participatory citizenship at the second stage. Eventually students gradually develop a strong sense of civic responsibility and competence through social inquiry and political action in the transformation process.
