| CD-ROM database systems are now a familiar sight in libraries of all types and sizes. Reference librarians have found that many patrons do need some type of instruction in order to effectively utilize CD-ROM databases. The purpose of this study was to compare four different methods of bibliographic instruction in order to determine which method would have the most effect on student learning. In this study, 120 students were given instruction on searching the PsycLit CD-ROM database. The students were divided into four groups, and each group was given a different method of instruction. The four methods of instruction were lecture, lecture utilizing an LCD, video, and computer-assisted instruction. The statistical technique used to perform the data analysis for this study was the one-way analysis of variance to test the significance levels among the groups. The t test was used to compare differences between the different groups. Seven hypotheses were tested at the 0.05 level of significance. The fifth null hypothesis tested in this study was rejected while the other six hypotheses were instruction was more effective in teaching students to search the PsycLit CD-ROM database system than the lecture method. Recommendations for future study include replication at other academic libraries, comparison of students with and without computer experience, and the use of videos to teach the use of other library sources. |
