Two experimental programs, designed to increase Scholastic Aptitude Test (SAT) scores of inner city, low achieving students by using computer-assisted SAT preparation, produced differing results. Forty volunteers from a nearby high school were assigned to two groups of 20 each--one experimental and one control group. The first program provided six weeks of after-school work on the Hayden computerized SAT preparation program to 20 inner city high school seniors. They pretested on the SAT in November, 1985 and posttested in January, 1986. During the instructional program, supervisors recognized the subjects' frustration with the difficulty of the vocabulary and their repeated wrong answers on the computer tests, as well as their lack of motivation to attend the program. Results for the experimental groups showed that pretest to posttest mean scores dropped 22 points on verbal and rose 20 points on mathematics. The second program provided a two and one-half-week program, eliminated conflicts by scheduling during school hours, and added training on the TestSense computerized program, which teaches test-taking skills and strategies. These students' pre- and posttested on the PSAT, showing mean post-program gains of 51 points in verbal and 40 points in math. Results of the second study are encouraging for use of computers in training inner city students in test-wiseness and SAT content. (JGL)
