If the period between twenty and thirty is the critical one in the formation of intellectual and professional habits, the period below twenty is more important still for the fixing of personal habits, properly so called, such as vocalization and pronunciation, gesture, motion, and address. Hardly ever is a language learned after twenty spoken without a foreign accent. Hardly, ever, indeed, can he even learn to dress like a gentleman-born. Hardly ever, indeed, no matter how much money there be in his pocket, can he eve n learn to dress like a gentleman-born.

One一Room Schools
One-room sohools are part of the heritage of the United States,and the mention of them makeo PeoPle
feel a longing for"the way things were".One-room schools are an endangered species,however.For more
than a hundred years,one-room schools have been systematically shut down and their students sent away to
centralized schools.As recently as 1930 there were 149,000 one-room schools in the United States.By 1970
there werel,800.Today,of the nearly 800 remaining one-room schools,more than 350 are in Nebraska.The
rest are spread through a few other states that have on their road maps wide-open spaces between towns.
Now that there are hardly any left,educators are beginning to think that maybe there 15 something yet to
be leamed from one-room schools,something that served the pioneers that might serve as well today.Progres-
sive educators have come uP with progressive-sounding names like"peer-group teaching"and"multi-age
grouping" for educational procedures that occur naturally in one-room schools.In a one-room school the chil-
dren teach each other because the teacher 15 busy part of the time teaching someone else.A fourth grader can
work at a fifth-grade level in math and a third-grade level in English without the bad name associated with
being left back or the pressures of being skiPped ahead.A youngster with a learning disability can find his or
her own level without being separated from the other pupils.A few hours in a small school that has only one
classroom and it becomes clear why so many parents feel that one of the advantages of living in Nebraska is
that their children have to go to a one-room school.What is the author's attitude towards one-room schools?
