Designed to assist schools in implementing developmental skills in the social studies programs for grades K-12, this guide is divided into seven sections. The first section, a literature review, cites publications on social studies skills. Section 2 gives an interdisciplinary view of shared skills in the New York state curriculum. Three skill charts in Section 3 are for developing a comprehensive skills program. Included are specific skills in getting, using, and presenting information; participating in interpersonal and group relations; problem solving; conflict resolution; decision making; self-management; decreasing egocentric, ethnocentric, and stereotypic perceptions; and developing constructive attitudes toward diversity, change, ambiguity, and conflict. Section 4 presents activities introducing or reinforcing social studies skills at particular levels. Section 5 suggests a procedure for implementing a social studies skills program and provides examples of record-keeping forms. In section 6, three assessment systems are included for checking student and program performances: a K-6 basic skill diagnostic test, an observational instrument, and a Project PASSS diagnostic system. The last section describes the monitoring of this social studies skills program. (NE)
