Have them practice first discussion as to the definition and then in groups of 4 or 5 begin processing the practices by working on a process as a group.  Send them out with the skills needed.  Don't just talk about it... use a scenario format.  This would be followed by discussion of :  Things you like that you'd never thought of,  Two things you don't believe you can do and describe how you will work on them., Finally put one group plan together and practice it with students in building their capacity.
