The Mathematics Learning Center provides materials and assistance to students in courses from Arithmetic through Calculus and Differential Equations. One component of the program is the Directed Independent Study (DIS) program which provides an alternative to classroom instruction in Arithmetic, Introduction to Algebra, College Algebra, and Trigonometry. After a testing procedure to determine course of study and preferable learning mode, students are guided by a computer through a program consisting of 12 performance-based units of instruction. Success rate for DIS students during the 1974-75 academic year was about 40%; it rose to 50% for the 1975-76 academic year and continued rising until 1977-78 when a Tutorial Study Lab was added and the success rate dropped. The number of students involved in the program rose from seven to 44 by 1977-78. Another increase was found in the number of student visits or contacts, computed daily, weekly, and monthly. Students showed a clear preference for individual tutoring, however, attempts have been made to limit tutoring and increase usage of less popular modes of instruction. Though there was a slightly higher percentage of minorities attending the Center than in the total student population, the profile of DIS students is fairly well representative of the student body.
