This  video compares GCE’s Fabric—its primary threads of interest—to elements of a layered diagram recently presented by Keziah De Fusco to her freshman and junior classes. The animation also introduces specific characteristics (Revisiting Professional Learning Communities at Work, 2008) that guide how GCE uses 21st century tools. Forthcoming entries will report on these expressions in greater detail. In the meantime, advance congratulations to those who locate in the video a modified version of a popular schematic that Daniel Burnham included in his Plan of Chicago (Hint: look up!).
