The present study examines the influence of faculty development– specifically the Professional Development Programme (PDP) atthe National University of Singapore (NUS) – on teaching styles.Canfield and Canfield’s Instructional Styles Inventory (ISI) (1988)is used to measure teacher-focused and student-focused teachingstyles in sample populations with and without PDP intervention, andanalyses are run for all disciplines combined. The findings suggestthat the PDP accelerates an overall shift towards student-focusedteaching styles. The paper identifies key issues and strategies forpromoting faculty development through PDP.
