     Driving a large truck over mountain roads is not the usual way that a schoolteacher begins her day-

especially if she is a preschool teacher. But Mrs. Beth Miller does this five days every week. Her unusual

schoolhouse on wheels is actually a truck. The back of the truck has been made into a classroom in order

to carry the advantages of modern education to remote areas of the state of West Virginia. In many rural

areas of this state it is impossible for small children to go to regular schools because of the many hills and

valleys of Appalachian Mountains.

     The purpose of the schoolhouse on wheels project is to develop basic skills and social behavior in

children three to five years of age. This is done through games, exercises, toys and simple handcrafts. The

schoolhouse on wheels concept also teaches the young children to recognize 300 to 400 words on the printed

page. This is a great advantage in helping the pupils to learn to read when they begin regular school. In its

three-year history the project has helped about 350 children in an area made up of five counties, an area of

20 000 square kilometers. The schoolhouse on wheels is part of the Appalachian Educational Laboratory, a

research effort paid for by the government. Besides the mobile classroom, other parts of the program include

lessons by television and visits to the homes of the students. The technique is very effective, and one teacher

can do the work of seven in a traditional educational system. As a result the program costs about 50% less

than the regular kindergarten.

     All these advantages of the schoolhouse on wheels have made both parents and school officials happy.

West Virginia plans to increase the program and to include it in the public school system so that more than

4500 preschool children can have this valuable learning experience.
