First Published in 2000. This is Volume 75, Number 3 of the Peabody Journal of Education and focuses on collaboration across campus, town and with K-12 schools. The issue provides descriptions of a range of ways in which universities and schools and colleges of education can provide leadership for collaborative ventures involving the wider community. The collaborative undertakings include working with community agencies, other schools or colleges within or external to the institution, P-12 schools, and business groups. The rationale for the theme is that in today's world the problems we are facing are so complex that solutions can no longer be generated and successfully implemented in a vacuum. Cross-disciplinary and cross-sector collaboration is required to have the desired impact. This necessitates collaboration.
