COLLEGIALITY RESEARCH FINDING: Students benefit academically when their teachers share ideas, cooperate in activities, and assist one another's intellectual growth. COMMENT: Although high student achievement is most likely in a school with high faculty morale and a sense of shared responsibility, most teachers are independent and believe that the responsibility of running their classrooms is theirs alone. In some studies, as many as 45 percent of the teachers report no contact with each other during the workday; another 32 percent say they have infre- quent contact. As a result, these teachers fail to share experience and ideas or to get support from their colleagues. Isolation may undermine effective instruction. Good instruction flourishes when teachers collaborate in devel- oping goals that emphasize student achievement. Effective schools have a climate of staff collegiality and use mutual support as a means of improving pupil achievement. School lead- ers in such schools set aside time for faculty interaction and provide specific opportunities for teachers and administrators to work together on such tasks as setting school policies, improving instructional practice, selecting textbooks, and strengthening discipline.
