Leading the way: changing the focus from teaching to learning in large subjects with limited budgets.

To lead positive change in the teaching practice of teams that service large numbers of diverse students from multiple degree programs provides many challenges. The primary aim of this study was to provide a clear framework on which to plan the process of change that can be utilized by academic departments sector wide. Barriers to change were reduced by adapting and utilizing Kotter's principals of change specifically by creating a sense of urgency and defining a clear goal designed to address the problem.
