Peer reviewedHayes, Donald P.; Wolfer, Loreen T.; Wolfe, Michael F. – American Educational Research Journal, 1996
Contents of 800 elementary, middle, and high school textbooks published from 1919 to 1991 were analyzed with regard to their levels of difficulty. Following World War II, there was a major decline in schoolbook difficulty which may have led to the subsequent decline in SAT-verbal scores. (MAK)

Peer reviewedWhittington, Dale – American Educational Research Journal, 1991
Calls for education improvement are often predicated on a decline in U.S. education. Past U.S. high school students' knowledge is examined through U.S. history test data from 1915 to 1925 and national achievement test data for 1932 to 1965. Evidence does not support a decline in student knowledge. (SLD)
