Hi Marta: I assume you're addressing the comment made by Samuel. I cannot comment for him. But within the scope of the discussion of Understanding Yourself as an Instructional Leader, flexibility could imply using different teaching styles (to match learning styles of students or specific topics), or it could imply altering a standard approach to presenting a topic in order to improve student learning. Perhaps a deeper meaning of flexibility would be a willingness to be open to self examination or peer-review or assessment in order to see oneself in a different light. This takes a bit of courage because it's hard to take personal critique. But the motivation is a true desire to become a better instructor. Regards, Barry
