There will always be places in the world where good schools don't exist and good teachers don't want to go, not just in the developing world but in places of socioeconomic hardship.

The best schools tend to have the best teachers, not to mention parents who supervise homework, so there is less need for self-organised learning. But where a child comes from a less supportive home environment, where there are family tensions perhaps, their schoolwork can suffer. They need to be taught to think and study for themselves.

Too often we see that teachers and educational administrators feel threatened by self-organized learning. They, therefore, think it is not learning at all.

We have to provide good teachers, good environment, community involvement with schools.

A tin roof is one of the greatest indicators of prosperity in the developing world.

I get the sense when I go out to the schools [that] the teachers will tell you how they feel. And the sense that I have about the teachers' feelings is they don't feel truly appreciated with what they are doing in the classroom.
