What Research Tells Us About Audio (and Video)
Chapter 7 explores the potential of audio as a learning platform. We lay the groundwork by looking at the historical relationship between spoken and written language, and at the evolution of recorded audio, from the phonograph up through books for the blind, books on tape, audiobooks, and podcasts. Compared with the research literature weighing reading in print versus digitally, relatively few studies have explored use of podcasts or audiobooks in educational settings, especially measured against reading equivalent written text. We review studies to date, distinguishing between audio files played alone (solo audio) and reading that combines listening to audio with following along in the text (audio + text). Simultaneous audio and text is a common technique with readers having learning challenges and with second language learners. Given rising use of video materials in education settings, we also consider research comparing viewing video versus reading text, and viewing video versus only listening to audio.
