At a staff meeting invite your guests to provide a description of their school, and discuss common issues or interests. Buddy-up teachers by grade level or subject area across the schools, and ask each 'team' to consider a joint project that could be conducted with students. Set up a listserv for all staff in the mentoring schools, and invite discussion on specific topics of interest. You may want to have someone begin the discussion with a short message or story, and then invite responses. Take the time to communicate and feel comfortable with one another.
Some relationships take a while to develop.
Provide the NIS Coordinator with updates of your mentoring relationships. Share with others what is working, and what might be improved. Be prepared to provide a more formal summary of your mentoring experience to share with other schools. For your assistance, SchoolNet has developed a Mentoring ToolKit which is available online. This ToolKit contains a 'primer' on mentoring, an annotated list of web resources and a list of a variety of sample mentoring initiatives in Canadian schools and school systems.
