This volume compiles technical reports of Title I Elementary and Secondary Education Act project evaluations conducted during the 1976-77 academic year in the school district of Philadelphia, Pennsylvania. The reports include rationale, expected outcomes, mode of operation, previous evaluative findings, current implementation, and attainment of objectives for each project. A series of comprehensive mathematics projects encompassed educable retarded and Title I students in grades 2-12, and focused on remedial assistance in computational skills through classroom, tutorial, and individualized instruction. Included was a project to reduce mathematics skill deficiencies in grades 2-6 by providing the schools with mathematics resource teachers. A series of comprehensive reading projects provided similiar remedial instruction. Other projects involved intensive reading; bilingual education, counseling, computer-assisted instruction, skill and learning centers, a multimedia center, and neglected and delinquent children. Also evaluated were a project to provide high school students with cultural and curriculum enrichment to motivate them to seek post secondary education, and a project employing local residents as school-community coordinators. Summer components of Title I projects are also examined. Favorable learning environments, reversal of some student underachievement trends, and increased parental participation are attributed to Philadelphia's Title I projects. (Author/JAC)
