This is a compelling, eye-opening portrait of two communities in Philadelphia with drastically different economic resources. Over the course of their 10-year investigation, the authors of this important new work came to understand that this disparity between affluence and poverty has created a knowledge gap--far more important than mere achievement scores--with serious implications for students' economic prosperity and social mobility. At the heart of this knowledge gap is the limited ability of students from poor communities to develop information capital. This moving book takes you into the communities in question to meet the students and their families, and by doing so provides powerful insights into the role that literacy can play in giving low-income students a fighting chance.
