As part of the Articulated Instructional Media (AIM) program at the University of Wisconsin which is intended to extend higher education to people who would not otherwise have opportunities for study, the Library School program was conducted to develop independent study courses for the four beginning core areas of librarianship. The purpose of this present study was to evaluate the first segment of the cataloging course which was used in three library science programs. The experiment involved four classes in cataloging and classification in which the control groups were taught by regular instructors and conventional lecture-laboratory methods and the experimental groups used the materials developed for independent study. These materials consisted of a programed text, an index, a number of appendices, resumes of the materials programed, and a group of books assembled for use in the final session. It was concluded that: (1) the learning achievement of students using the independent study materials is sufficiently high to justify their use in teaching the same material now taught by conventional classroom methods, (2) students using the materials reacted favorably to them, and (3) retention of subject matter learned through independent study is not different from the retention of those students who had been taught in classroom situations. The attitude questionnaire showing student responses is appended. (JB)
