Recounts research regarding elementary education majors' familiarity with world geography. Reports poor performance among 253 students on a geography test designed for use at the high school level. Indicates that the education majors performed best on map reading activities and worst on identification of land forms. Calls for further research. (SG)

Many students in the United States do not possess a sound geographic vocabulary. This study compared two instructional methods, drill and varied activities, that might be used to develop that vocabulary. Eighth-grade social studies classes at three sites (one urban, one rural, and one transitional) were used to assess learning of the 50 United…
