Comparison between the results of a 1977 and a 1982 census of secondary school course offerings in Illinois indicated that in high schools the proportion of enrollment in all social studies combined decreased from 1977 to 1982 but the proportion of enrollment in the traditional courses remained relatively stable. Census data were collected from 489 public junior high schools and 719 high schools. The traditional social studies courses of United States and American history, world history, and American government accounted for over half of all the social studies enrollment in high schools. United States history and social studies courses accounted for the majority of enrollment in junior high schools. High schools of 1000 or more enrollment offered an average of twice as many social studies courses as schools with less than 200 enrollment. Almost half of the social studies courses offered in high schools are full year courses. In junior high schools, over 80 percent of the courses are a full year in length. Almost three-fourths of the social studies courses offered in high schools are elective, although some may satisfy a general requirement for credit in social studies. (IS)
