At the heart of the educational enterprise are human relationships. Whatever educational philosophy we adhere to, whether faith in streaming and grammar schools, radical anarchist traditions or modernist school improvement perspectives, the people engaged in the educational encounter are seen as central to shaping the meaning and success of the experience. So much so that one of the most commonly expressed fears about the relationship between education and technological change is the idea that we may one day replace educators with machines and that the essential humanity of the encounter may be lost.
