Principal+Leadership

What does an effective leader need to do to change the culture of a school to the 21st Century learning?

The leader simply needs to show that he/she is sensible to the technology skills of the current staff. Once that is established, I think that the leader needs to slowly infuse their philosophy within the building so there is buy on from the staff. Once you have buy in, staff won't feel imposed on, and they would work together with that leader, to make sure the school's goal is being met!
