Some institutions of higher learning have invested considerable resources to diffuse iPods and MP3 devices though little is known about learning outcomes tied to their use. Dual-coding and multimedia learning theories guided the development of a typical college lecture so that it could be presented in a combination of audio and visual forms across small-screen and large-screen displays. A 3 (audio, audio/text, and audio/video)x2 (iPod screen vs. computer screen) factorial experiment, was conducted to examine how systematic variations in the capability of commonly used MP3 technologies facilitate learning. Scores indicated that dual-coded presentations were substantially more potent learning aids. Results are discussed in terms of developing best-practice strategies for those who wish to implement iPod technology into course curricula. (Contains 1 table.)
