This paper investigates the difference in achievement among 20 University of Utah students of modern standard Arabic. One group of 11 students followed an intensive eight-week summer course, and a second group of nine students studied the same course during a regular academic year. Also reported on is the correlation between achievement and language aptitude as tested by the Modern Language Aptitude Test (Carroll and Sapon's "Modern Language Aptitude Test," New York, The Psychological Corporation, 1959). The author points out the limitation of applicability of the study due to the heterogeneity and small size of the sample, but notes "that there is a rather high correlation between the MLAT as a predictor and the achievement test" results. The non-intensive group seems to have done slightly better on the final achievement test than the intensive group. (MK)
