This monograph describes a number of successful solutions that have been used in schools involved in school improvement planning. Problem-solving strategies used by schools across the United States to address various situations are described, in which each school focused on student achievement and teaching learning for all students. The practices, based on effective schools research, were utilized in seven elementary schools, six junior high and middle schools, five high schools, and one school district. Programs, each of which is described in this report, addressed leadership training, alternative learning, reading improvement, participative action research, at-risk students, student mediation, individualized tutoring, mathematics achievement, and parent involvement. Data-based results are described and a contact source for each school is provided. (LMI)
