One-room schools are part of the United States, and the mention of them makes people feel a
vague 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 were 1,800.Today, of the nearly 800 remaining one－room schools,
more than 350 are in Nebraska.The rest are scattered through a few other states that have on their
road maps wide－spaces between towns.
Now that there are hardly any left, educators are beginning to think that maybe there is something
yet to be learned from one－room schools, something that served the pioneers that might serve as well
as today.
Progressive educators have come up with progressive－sounding names like "peer－group teaching"
and "multi－age grouping" for educational procedures that occur naturally in the one－room schools.In
one－room
schools, the ch
ildren teach each other because the teacher is 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 shame 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.In
larger urban schools today, this is called "mainstreaming". A few hours in a small school that has only one
classroom and it becomes clear why so many parents feel it one of the advantages of living in Nebraska
that their children have to go to a one－room school.
