Of course, this shift in the educational paradigm has physical repercussions as well: With the new generations growing up with near limitless access to the internet, teachers must take on the role of a guide rather than a gatekeeper, helping students along their educational journey rather than dragging them kicking and screaming. Nevertheless, this is the 21st century, the informational age, and teachers are no longer the guardians of the knowledge gateway. Save this picture! Escuela Saunalahti / VERSTAS Architects: segundo nivel. What comes to mind when you see a long hall of closed doors, that you can't be in without permission, and a bell that tells you when to come in, when to leave, when class starts, when it ends? What does that look like to you? In the US, many of the same people who designed prisons also designed schools. The American architect said in a recent interview with the Colombian newspaper El Tiempo that his interest in educational architecture began when he received assignments that were a far cry from the traditional school building: what he calls the "prison model." When asked why today's schools were designed like prisons, Locker responds: With decided conviction and vast experience in architectural education, Locker says that we are limiting ourselves by continuing to use the "prison" model and by falling back on the old 20th-century formula of teachers passing on rigid and uninspiring knowledge to students with no concern for their different interests or abilities. Locker was in Colombia assessing the Department of Education in Bogotá and advising architects and construction companies about a new model of study with the ability to address society's current social and cultural changes.
