The Pennsylvania School Improvement Program (PSIP) was initiated to develop and demonstrate curriculum improvement strategies in basic skills areas at the local school level in cooperation with the Pennsylvania Department of Education and several research and development agencies. The PSIP process is a problem-solving method with five major steps: school visitation by the PSIP curriculum specialists, needs assessment, knowledge consolidation, product selection, and product implementation and evaluation. The process depends on the mediation of a linker, a curriculum specialist trained to help teams at the district level perform PSIP activities and obtain access to information and resources at the state, regional, and national levels. The activities coordinated by the linker are divided into 23 distinct modules, described in this document which is intended for use by those trained in the PSIP process. Information provided on each module includes purpose, objectives, expected outcomes, time and material requirements, activities, follow-up work, alternative strategies, and agendas. Master copies of handouts and transparencies used in the workshops and activities of each module are included. (Author/PGD)
