This issue features the opinions of some highly respected, but often controversial, educators who stand outside the mainstream of education reform. They often advocate more structured and top-down approaches to the problems of urban students as they consider the standards that must be created to promote achievement for all students. "No Magic Tricks: It's a Systems 'Thang'" by Anne C. Lewis argues that urban districts can provide the systemic context needed to make city schools places of high achievement for students and teachers. "What Works with City Kids: An Effective School Model" by Lenaya Raack presents the visions of educators Asa Hilliard and Barbara Sizemore for creating successful urban schools. "First in the World: Federal Math and Science Initiative Targets City Schools" by Dan Weissmann recounts efforts of the National Science Foundation to improve urban schools. "Full-Service Schools and High-Risk Youth: Collaborating To Make a Difference" by Joy Dryfoos describes the combined efforts of human services providers and school personnel. Four former urban superintendents offer suggestions and challenges for today's urban schools in "Unsung Heroes: Ex-Superintendents Speak Out." Finally, this issue's CITYSCHOOLS Profile by Donna M. Williams looks at the work of Lisa Delpit, a crusader for urban and minority children. (SLD)
