The Elementary School Journal Volume 86, Number S O 1986 by The University of Chicago. All rights reserved. 0013-5984/86/8603-0002$01.00 Teachers have strong opinions about parent involvement. Some believe that they can be effective only if they obtain parental assistance on learning activities at home. Others believe that their professional status is in jeopardy if parents are involved in activities that are typically the teachers' responsibilities. The different philosophies and beliefs of teachers reflect the two main, opposing theories of school and family relations. One perspective emphasizes the inherent incompatibility, competition, and conflict between families and schools and supports the separation of the two institutions (Parsons, 1959; Waller, 1932; Weber, 1947). It assumes that school bureaucracies and family organizations are directed, respectively, by educators and parents, who can best fulfill their different goals, roles, and responsibilities independently. Thus, these distinct goals are achieved most efficiently and effectively when teachers maintain their professional, general standards and judgments about the children in their classrooms and when parents maintain their personal, particularistic standards and judgments about their children at home.
