From 1986 to 1988 the associates of the Enhancing Secondary Science Education through Science/Technology/Society (STS) for Urban Minority Youth Project worked toward establishing guidelines for STS in secondary science. The guidelines, based on study, research, discussions, and a consensus-building process, are presented along with 12 background papers by various authors. Three main ideas emerged in the process of developing these guidelines: (1) it is critical for our society to reverse the pattern of school-related difficulties and failures among members of disadvantaged minority groups; (2) STS as a curriculum emphasis has an important and unique contribution to make to the secondary science education of urban and minority students; (3) in order for STS to make this contribution, it must be shaped to empower the learning of disadvantaged minority youngsters in urban schools, and this situation requires new role relations among teachers and school leaders, learners, and members of the urban minority communities. A formulation of a 1-year course outline for an STS course for urban and minority students is presented, as well as a review of major high school level STS curricula in light of the project guidelines. Also included is a model for infusing STS studies into urban school science curricula. (JB)
