While a few years old now (TED 2006), this talk by Sir Ken Robinson still makes an entertaining and profoundly moving case for creating an education system that nurtures, rather than undermines, creativity. Robinson asserts that children are exceptionally innovative and that schools suppress this creativity as children pass through the educational system.
Personally I don't believe "schools" suppress creativity. By that I mean the physical buildings or the teachers. I believe that it is, in fact, the creativity of schools and teachers that are suppressed, which may in turn to lead to the undermining of children's' creativity and innovation. Government policies, poorly constructed syllabi, lack of facilities, terminal state exams, a general lack of funding, uninspiring buildings, disputes over salaries, public perception of teachers and schools, all contribute to this stifling effect. Some schools, my own included, try to overcome these barriers and do manage to promote a sense of wonder in education through innovative approaches to teaching and learning. However, not all of these can be overcome by schools alone.
