A computer software package has been developed to teach and test students on the Rules for Alphabetical Filing of the Association of Records Managers and Administrators (ARMA). The following computer assisted instruction principles were used in developing the program: gaining attention, stating objectives, providing direction, reviewing prerequisite materials, presenting information, providing practice, and assessing learning. The package was tested in a University of Nebraska-Lincoln office management course with 18 subjects randomly selected to use the computerized program with the ARMA publication Rules for Alphabetical Filing, while the control group studied solely from the publication. After 4 weeks, students were given a 40-problem test. Results showed no significant mean score difference between groups, but the experimental group spent an average of 2 2/3 hours learning via the computer and 2 1/2 hours studying from the text, while the control group spent an average of 4 hours studying. Based on field testing and review at the secondary, community college, and university levels, revisions have been made and a separate testing program has been developed. This report includes a three-item reference list, six figures, outline summaries of the instructional and testing programs, and a list of system specifications and requirements. (LMM)
