Reading aloud is a widely accepted and successful practice in elementary school classrooms, but is rarely found in middle school classrooms (Allen 2000). However, results from initial research on reading aloud in secondary classrooms support the practice (Ivey and Fisher 2006). The benefits of reading aloud are many, but two benefits are particularly valuable in science classes: motivation and vocabulary acquisition (Richardson 2000; Beck, McKeown, and Omanson 1987; Jenkins, Stein, and Wysocki 1984; Nagy, Herman, and Anderson 1985; Robb 2003). This article describes how to use read-aloud strategies to introduce new concepts, build vocabulary, and supplement your text. (Contains 37 resources and 5 online resources.)
