One-room schoolhouses, or One-room schools, have been commonplace throughout rural portions of various countries, including Prussia, Norway, Sweden, the United States, Canada, Australia, New Zealand, the United Kingdom, Ireland, Portugal, and Spain. In most rural and small town schools, all of the students meet in a single room. There, a single teacher teaches academic basics to several grade levels of elementary-age children. Recent years have seen a revival of the format. One-room schoolhouses can also be found in developing nations and rural or remote areas undergoing colonization.
In the United States, the concept of a "little red schoolhouse" is a stirring one, and historic one-room schoolhouses have widely been preserved and are celebrated as symbols of frontier values and of local and national development. When necessary, the schools were enlarged or replaced with two-room schools. More than 200 are listed on the U.S. National Register of Historic Places. In Norway, by contrast, one-room schools were viewed more as impositions upon conservative farming areas, and, while a number survive in open-air museums, not a single one is listed on the Norwegian equivalent to the NRHP.
