Like a book group. Exploring new and better ways of teaching. The group poses questions and tries to build answers. They share tricks and tips and resources and stories. Trial and error.
Every teacher becomes a technology coach.
Good at something. Prepared to help others accomplish what they desire. The best strategy is to share responsibility broadly. One person specializes in crunching numbers with spreadsheets to understand relationships. Another teacher becomes skillful with search engines and information problem-solving.
