TEACHING AND LEARNING IN RHYTHM: Inspiring post here from Mr. Grant Glitchman, former marine geologist and current CFO at Francis Parker School. He uses the physical properties of sound and electricity to paint two very different views of the classroom. Rhythm and frequency, he notes, "measure how often something changes," whereas assembly lines measure output of "units, parts, and completed items." Very intriguing analogies -- in which camp does your classroom reside?
