This paper reviews the problems of antisocial student behavior in schools, tries to identify causes, and examines programs and procedures for remediating and preventing such behavior. This review focuses particularly on senior and junior high schools and all forms of antisocial, aggressive, disruptive behaviors that interfere with school functioning. The report concludes that the problems of school discipline, violence, crime, vandalism, and truancy have grown to large proportions in many American schools. Principals and school boards often seem reluctant to admit the problems that begin or are caused by forces outside the school. Poor home conditions, television violence, a climate of crime in the community, gangs, and peer crime influences are all initial contributors to the problems that surface in schools. But, the author contends, the school also contributes with poor teaching, a negative school climate, a dose of failure for many students, and irrelevant curricula. The school can take positive action along with other youth agencies to alleviate the problem and even create a positive social and academic climate in which all youth can succeed. A set of recommendations for action by educators is presented. (Author)
