To cope with the rapidly changing higher education climate, teachers need agency to act proactively in initiating and steering changes in practice. This paper describes an academic development activity in the form of a Change Laboratory, an intervention method based on Cultural-Historical Activity Theory, to facilitate agency among teachers. The results of the study indicate that transformative agency emerges when teachers are given the opportunity to analyse, envision, and redesign their practice collaboratively. This has implications for academic development, suggesting that activities facilitating discussion, analysis, and criticism of current practices are needed to support the development of agency.
