The comparative effectiveness of three pedagogical techniques (use of a chalkboard, use of an overhead projector, and use of computer-projected software) was examined. The study involved students in three financial accounting principles classes at one university. Each student was exposed to each method for one third of the semester, and all completed daily quizzes plus midterm and final exams. The results of the study provide no evidence of overall differences in student learning among the three methods. Learning, however, was found to be related to students' preferences for pedagogical method—that is, exam grades were higher when students' preferred methods were used in the classroom.
