ABSTRACT  The national decline in the Scholastic Aptitude Test scores in verbal ability over the past several years has indicated a need for remedial work with vocabulary development. A course in the enlargement of students' English vocabulary through the study of Latin and Greek roots and their derivatives has been developed by the Department of the Classics at the University of Illinois. A unique component of the class is that it makes use of computer-assisted instruction as available on the PLATO IV system. Enrollment in less than a year has increased from thirty-five to over 400, and some students have improved as much as forty percentile ranks in their verbal aptitude as measured on standardized tests.
