Larry Cuban talks about one of the most successful reforms ever introduced to public education: graded classrooms, in this blog post, Ungraded schools: Past and Present. Of particular note is the notion that part of the reason we have such difficulty changing this practice is the design of our school buildings. While there are many forces that work to keep graded classrooms in place, the "egg crate" design, where each teacher has his or her own classroom, limits teachers' ability to create multi-age classrooms, create workstations that integrate technology, and work in teams with large groups of students.
This post is the second of a three-part series Cuban wrote about the forces that work against today's efforts to transform public schools to address the needs of today's learners. Interesting reading for anyone interested in education reform.
