Five years after Consortium on Chicago School Research (CCSR) research revealed a "digital divide" among Chicago Public Schools (CPS) and limited computer usage by staff and students, this new study shows that district schools have overcome many of these obstacles, particularly in terms of technology access and use among teachers and administrators. However, technology is not yet a routine component of most students' schoolwork. Using surveys of students, teachers and principals from 2001 to 2005, this report shows how technology integration in CPS schools has changed over time. It also examines the barriers to technology integration that principals perceive still remain in their schools. The following are appended: (1) Further Details on the Survey and Methods Used in the Analyses; and (2) Details of the System Trend Analyses. (Contains 16 figures and 2 tables.)
