The Flex Lab at Santa Fe Community College, in New Mexico, is a self-paced, computer-assisted training center that allows students to accommodate college credit courses into their schedules. The Lab offers courses in introductory computers, keyboarding, and various computer programs and emphasizes several features of the Personalized System of Instruction (PSI) developed by Fred Keller. The aspects of the Lab curriculum which reflect the PSI include the following: (1) discrete modules, reflected in the six sequential modules of the one-credit Business and Office Technology course; (2) an emphasis on individual study, reflected in the self-paced, independent nature of the curriculum; (3) the use of supplementary instruction, provided by group orientations to the lab at the start of each semester; (4) the use of unit exams, which is very important in the Flex Lab environment of decreased instructor-student interaction; (5) the use of proctors, who are available for most of the hours that the Lab is open to answer questions; (6) self-pacing, which helps expedite the completion of prerequisites, learn at a more flexible rate than in a traditional classroom setting, and negotiate work and family obligations; and (7) mastery, encouraged by instructors who return assignments for revision before final grading. Evaluative research of the PSI method indicate that students achieve better scores, retain information longer, and show more interest than traditional students. (ECC)
