Your post conjures up TWO questions for me:
First one that comes to mind is:
Is there a specific intent you have for teacher team building?
Examples of possible intentions:
* setting or changing a tone/climate of a school * teacher
requested team-building activities * district administration
mandate requirement for each site to participate in team
building * boost low-morale or eliminate/lessen strife between
staff members
The second one that comes to mind is:
Are team-building activities really necessary? (And, does
mandating a staff to participate in them authentically create
the sense of community they were intended to establish?)
