Can Dispositions Be Taught?

I don't think dispositions can be taught in a traditional sense.  It is not something that can necessarily be articulated and then all of the sudden the students have learned to be humble or authentic people, but I think the teacher can lead by example.  These dispositions require experience and reflection on these experiences.  I think in order to enhance the dispositions of teachers, there should be outlets for teachers to express their feelings, where they can grow and be supported as teachers even once they are out of school and in the classrooms.  It is important for the teacher to understand his or her true self in order to be effective in the classroom.
