It is hard not to feel that there must be something very wrong with much of what we do in school, if we feel the need to worry so much about what many people call 'motivation'. A child has no stronger desire than to make sense of the world, to move freely in it, to do the things that he sees bigger people doing.
On a certain level, homeschooling is all about socialization. Whatever the teaching methods used in school or homeschool, it is ultimately the social environment itself that distinguishes homeschooling from conventional school. This social environment includes the nature and quantity of peer interaction; parental proximity; solitude; relationships with adults, siblings, older children, younger children, and the larger community; the ways in which the children are disciplined and by whom; and even the student-teacher ratio and the overall environment where the children spend their time.
To confuse compulsory schooling with equal educational opportunity is like confusing organized religion with spirituality. One does not necessarily lead to the other. Schooling confuses teaching with learning, grade advancement with education, a diploma with competence, and fluency with the ability to say something new.
