This paper reports on a study conducted to determine if PowerPoint presentation is the most effective medium to explain two reference books: "The Storyteller's Sourcebook" and "A Guide to Folktales in the English Language." A secondary purpose was to see if the students who saw the PowerPoint presentation received higher grades/scores for an assignment than those who only received oral instructions. Participants in this study were the 122 undergraduate students in four sections of a Children's Literature course at Bowling Green State University. All sections received oral instructions, and two sections received additional instruction through a PowerPoint presentation. After the assignment was graded, students completed a survey on demographic information and attitudes toward the session. Demographic and attitude data was analyzed by simple frequency counts and cumulative frequency percentages, and a one-tailed t test was used to compare the attitude data. Results indicated a slightly higher number of PowerPoint students needed help from library staff. The non-PowerPoint students felt the presentation was more helpful in understanding the reference books. The non-PowerPoint groups felt the presenter was more enthusiastic. Grade comparisons were not statistically significant. Nine appendices contain: assignment descriptions; hands-on exercise; PowerPoint slides; cover letters; surveys; and six selected sources. Contains 13 references. (Author/DLS)
