In recent years, there has been a growing body of literature investigating metacognition in second language (L2) listening (e.g. Cross, 2010; Vandergrift & Goh, 2012; Vandergrift & Tafaghodtari, 2010). The theoretical underpinning of the majority of these studies is that metacognition and listening are individual psychological processes. This led to a limited understanding of metacognition in listening that highlights the regulation of oneself, whilst disregarding the communication partner and the wider context. The present study contributed to the existing body of literature by investigating and re-conceptualising metacognition in L2 listening. Informed by a sociocultural and dialogical perspective on discourse and thought, this thesis offered new insights that recognise L2 listeners’ metacognitive awareness and activities as reciprocal monitoring and control processes. International students for whom English was a second/foreign language participated in the study. They worked in pairs on a collaborative problem-solving task and their interactions on this task were video-recorded. Directly after the task, individual interviews with each member of the pair were conducted to gain their accounts of how they perceived the task and how they monitored and regulated the interaction. A grounded theory informed approach was used to analyse the interview data, and a conversation analysis informed approach was used to analyse the interaction data. The findings of this study have established that a wider view of metacognition in L2 listening is required. The re-conceptualisation, underpinned by existing theories and deriving from the study’s empirical data, moved beyond conventional views of metacognition, and argued that the monitoring and control processes in listening are dialogical and reciprocal. This re-conceptualisation was encapsulated in the term Metacognitive Discourse Awareness (MDA). The central tenet of the MDA framework is that metacognition in listening involves the complex regulation of the discourse, thought and social-affective dimensions. This multidimensional framing of MDA entails the listener’s awareness of his/herself as the co-regulator of the other(s) in the reciprocal relationship in which meaning is socially co-constructed and negotiated. This study thus foregrounded the situatedness of the monitoring and control processes in L2 listening and the connections within, between and across the thought, discourse and social-affective dimensions. The thesis concluded with recommendations for L2 teachers and learners to develop a broader understanding of metacognition in the listening process so that this understanding can have an impact on practices in the increasingly diverse global higher education context.

The aim of this investigation was to examine the role of visual elements in second language listening comprehension when digital video was used as a mode of presentation. Despite the widespread use of video in listening instruction, little is known at present about how learners attend to dual-coded media and, in particular, how visual elements may influence comprehension processes.

In this study I addressed three problems related to how sandhi-variation, the adjustments made by speakers to the speech stream, filters comprehension for second language listener processing. The first was the need to better understand proficiency problems encountered by L2 listeners as they decode the speech stream with the phonological features of sandhi-variation, elision and assimilation, by investigating the item difficulty hierarchy of the phenomena. The second was the scarcity of research on aural processing abilities of second language learners in relation to their understanding sandhi-variation in aural texts. The third concerns the lack of research investigating links between learners’ backgrounds and their ability to handle listening texts, especially variations in the speech stream in target aural texts. The purpose of this study was threefold. My first purpose was to investigate the item difficulty hierarchy of sandhi-variation types that learners have in relation to L2 listening proficiency. My second purpose was to evaluate links between aural input containing elision and assimilation and second language aural processing, to provide insight into how learners deal with sandhi-variation as they process such input. My third purpose was to investigate through the use of interviews the aural input that participants have encountered prior to the interventions of this study, to help explain which types of aural input can facilitate intake. Twenty-five first- and second-year Japanese university students participated in the current study. The participants completed a series of instruments, which included (a) a Test of English as a Foreign Language Paper-Based Test (TOEFL PBT), (b) a Listening Vocabulary Levels Test (LVLT), (c) a Modern Language Aptitude Test–Elementary (MLAT-E), (d) a Pre-Listening in English questionnaire, (e) an Elicited Imitation Test (EIT), and (f) a Background and Length of Residency interview. The EIT was used as a sandhi-variation listening test with two component parts (i.e., elision and assimilation) and two sub-component parts (e.g., two different utterance rates), using elicited imitation. Finally, the participants were interviewed about their language backgrounds to gauge their understanding and feelings about English. An empirical item hierarchy for elision and assimilation was investigated, along with the determinants of the hierarchy. Overall, the tendency was for items with elision and assimilation to be more difficult. Results also indicated that the two input rate variables combined with elision and assimilation affected the non-native participants’ listening comprehension. Moreover, the strength of the relationship between two measures of the participants’ language ability, proficiency and aptitude, and their comprehension of items with and without the phonological features of elision and assimilation, were investigated. The results confirmed a positive relationship between language aptitude as measured by the MLAT-E and the comprehension of the phonological features of elision and assimilation. Finally, the results indicated that there were no significant, positive correlations between English language proficiency scores and both the Pre-Listening Questionnaire, which measured the participants’ feelings about second language listening, and the Background and Length of Residency Interview. More research needs to be conducted to determine how learners’ backgrounds are related to listening comprehension in order to better prescribe aural input in second language listening classrooms. / Teaching & Learning
