This book presents reviews of programs for elementary and secondary schools that are widely available and have some evidence of effectiveness in terms of student achievement. It also discusses district-level strategies for introducing proven programs. The comprehensive and objective evidence offered will help school and district administrators select the right program for their schools, whether school wide programs for Title I projects or for schools that get funding from whole school legislation. Criteria are outlined for program effectiveness and replicability. Relatively few programs would meet all the criteria for rigorous evaluation, but evaluative data are reported as available. Program descriptions and evaluations are grouped according to their broad objectives. The following chapters are included: (1) "Show Me the Evidence!"; (2) "Schoolwide Programs"; (3) "Classroom Instructional Programs"; (4) "Dropout Prevention and College Attendance Programs"; and (5) "School District Strategies To Support School Change." (Contains 198 references.) (SLD)
