Beginning vision with unmet needs is a good place to start.
Who in your learning community continues to struggle--struggle academically, socially, physically, emotionally?
Who in your learning community is distanced from the tools, materials, processes, content, skills, concepts, and success possible?
Who in your learning community demands more attention and care?
Typically helping those most in need serves to help all in the community.
This is a good place to start when creating vision.
