The Effectiveness of Multiple Media Tools in L2 Listening: A Meta-Analysis

Introduction

Listening comprehension is considered to be a very crucial language skill because it appears at “the early stages of L2 learning” (Nation & Newton, 2009, p. 37), enables learners to receive language input, and facilitates the emergence of other language skills (Vandergrift & Goh, 2012). According to Burley-Allen (1995), the average time spent on basic skills during the daily communication process is 35% for speaking, 16% for reading, 9% for writing, and 40% for listening. However, listening has also been described as “the least understood and most overlooked of the four skills (listening, speaking, reading, and writing)” (Nation & Newton, 2009, p. 37). The continuous speech-flow makes the listening comprehension process hard to capture and analyze. For instance, in the real spoken language, listeners cannot slow it down or break it down into manageable chunks. Therefore, effectively teaching and learning L2 listening is the greatest concern for most of the L2 educators.

Several models have been developed to explain how listening process functions, including the bottom-up model, the top-down model, and the interactive model (Flowerdew & Miller, 2005). In the bottom-up model, listeners start with the small units in the acoustic message, such as individual sounds, to achieve listening comprehension. The top-down model suggests that learners rely on prior contextual knowledge and utterance interpretations in processing a text. Allowing for the individual variations in listening processing, the interactive model synthesizes the bottom-up and top-down models. With regards to listening activities, Rost (2011) discusses six widely used instructional designs in L2 listening, namely, intensive listening, selective listening, interactive listening, extensive listening, responsive listening, and autonomous listening.

In light of the possible factors in listening passages that influence listening success, Buck (2001), and Vandergrift and Goh (2012) provide very comprehensive summaries. Specifically, the statistically significant predictors of listening comprehension in listening passages that have been empirically tested are vocabulary/lexis, syntax/grammar, topics, number of the topics, speed, pronunciation/intonation, and multiple media. Table 1 summarizes these predictors and the corresponding empirical studies.
