An example of such collaboration is described by Abilock and Lusignan (1998), in which a
school librarian and science teacher partnered to teach a collaborative project-‐‑based unit on global
warming. The two educators worked together to plan and implement a unit in which their
students took on the viewpoint of a participant in the Kyoto Conference, investigating and
developing arguments from a range of perspectives including industry, environmental groups,
and scientific research.
