One of the benefits of working at the middle school level is the opportunity to work with colleagues in a variety of content areas; this not only makes work more interesting, but offers a multidisciplinary approach to learning that ultimately benefits the students. In the Londonderry (New Hampshire) School District, collaboration between classroom teachers and school librarians has been integral to the ongoing success of a district-wide library instructional program. In this article, the authors describe the development of a successful coteaching effort at Londonderry Middle School. They also describe a lesson which used historical stories and provided students with an opportunity to engage in such 21st-century learning skills as cooperation and collaboration, technology integration, and critical and creative thinking.
