The growth of post-secondary English for Academic purposes (EAP) programs along with researchers awareness and interest in leveraging technological tools in support of student-centered learning (Prensky, 2012) fueled this research. This study examines learners beliefs towards technology use in a Canadian EAP university program. Using a multi-phased, grounded-theoretical exploratory case study approach, the research uses complementary data sources including two online surveys conducted at the beginning and at the end of the program, class observations, individual students digital diaries, stimulated recall interviews, and focus group interviews. The study examines 16 student participants beliefs toward technology use and the factors that influence and constrain students use of technology. The research was informed by a constructivist view of language learning and explores EAP students interactions with technological tools to gauge their beliefs towards tech use in learning English. Furthermore, Bensons (2011) learner autonomy framework was used to investigate the development of learner autonomy. This framework is believed to provide an additional research lens in understanding EAP students interaction with technology, impacting their evolved belief systems. Comparisons between the surveys show that overall students beliefs toward technology use became more positive from the beginning to the end of the course when students became more competent with increased technology exposure and use. Students realized the benefits of using technological tools and adopted some 21st century skills in learning English (Dede, 2010). A heightened critical awareness among students towards tech use and some emerging individual language learning behaviors were reported in their digital diary posts and stimulated recall interviews. This specific finding transpired as one of the pedagogical factors- participating in the research study. Data from embedded case studies revealed contextual and

IMPLEMENTING A CULTURAL HISTORICAL ACTIVITY THEORY APPROACH TO BLENDED language learning

IMPLEMENTING A CULTURAL HISTORICAL ACTIVITY THEORY APPROACH ...

学位级别：博士

The qualitative study presented in this thesis investigated the activity of ab initio Irish language learners participating in a real world Blended learning (BL) course Introduction to Irish which took place in Carnegie Mellon University, 2016. The course's design included a mixture of 'off the shelf' online language learning technologies and traditional language learning resources. Taking the BL course's weekly sub-activity systems as the unit of analysis, this thesis addresses the research question of 'What contradictions emerge in a BL course for ab initio language learners?'. The research question was pursued by adapting a Cultural Historical Activity Theory (CHAT) based methodological approach and research instruments developed by Prof. Francoise Blin in her 2005 study on the development of learner autonomy within a hybrid French language course at Dublin City University. In this study, Blin's CHAT-based approach was used to identify contradictions within the activity system of the blended course. Effective elements within the course's design and their relationships to one another were also identified. The study's findings suggest that CHAT provides a sound conceptual framework to record and analyse learners' activity within newly designed BL courses. Practically, the study illustrates how Blin's CHAT- based coding scheme can be adapted to identify contradictions in ab initio BL courses. The study also illustrates how CHAT can be used to inform ab initio BL course design. Importantly for researchers studying BL environments, the findings suggest that working from a CHAT perspective facilitates the documentation of face-to-face and online activity both historically and within the course's larger social context. Importantly for language instructors, the main findings of the study suggest that the; 1. language teacher played an important role in facilitating communication among the ab initio language learners in the target language, particularly within the face-to

This paper presents our Mandarin pronunciation quality assessment system for the examination of Putonghua Shuiping Kaoshi (PSK) and investigates some measures to improve the assessment accuracy. In this paper, a selective speaker adaptation method is studied. In the adaptation module, we select well pronounced speech as the adaptation data, and adopt Maximum Likelihood Linear Regression (MLLR) to update the speaker-independent (SI) acoustic model. Besides the triphone based acoustic model, the monophone based acoustic model is also applied to our system. Further improvements are obtained by combining posterior probabilities computed with triphone and monophone based acoustic models using Support Vector Machine (SVM) to assess the goodness of pronunciations. The experiment results show that the average correlation coefficient (ACC) between machine and the human scores achieves 0.8549, almost equivalent to ACC between different experts. The improved system achieves usable performance in actual applications.

This article explores the effects of collaborative reverse subtitling as an activity for the promotion of writing skills in English as a second language. An initial analysis is undertaken of the pros and cons of the role of translation in second language learning historically and the role of information and communication technology in this process, with special attention being paid to recent initiatives on the didactic use of audiovisual translation in the form of subtitling, and the evidence of their efficacy obtained so far. Subsequently, a completed research project is described, which was aimed at promoting second language learning among distance learning university students through collaborative reverse subtitling. Specifically, the project aimed to explore both the potential of a guided subtitling activity for the development of written production skills, and also the dynamics of undertaking such an activity collaboratively, in order to gain insights on the social, cognitive, metacognitive and transfer mechanisms that can be activated in collective study. Finally, we reflect on the need to accumulate evidence on multimodal translating scenarios combining individual and collective work for the development of communicative language competences, through further research and classroom use, in order to consolidate and refine these findings.

In this paper we describe the language resources developed within the project "Feedback and the Acquisition of Syntax in Oral Proficiency" (FASOP), which is aimed at investigating the effectiveness of various forms of practice and feedback on the acquisition of syntax in second language (L2) oral proficiency, as well as their interplay with learner characteristics such as education level, learner motivation and confidence. For this purpose, use is made of a computer assisted language learning (CALL) system that employs Automatic Speech Recognition (ASR) technology to allow spoken interaction and to create an experimental environment that guarantees as much control over the language learning setting as possible. The focus of the present paper is on the resources that are being produced in FASOP. In line with the theme of this conference, we present the different types of resources developed within this project and the way in which these could be used to pursue innovative research in second language acquisition and to develop and improve ASR-based language learning applications.

Golden acoustic models, which are built or optimized using standard pronunciation data, are widely used in automatic pronunciation quality assessment. However, this work points out that because of the mismatch between training and test, golden acoustic models are unable to accurately measure the pronunciation quality for accented speeches. To deal with the problem, this paper presents a novel approach which uses both standard and non-standard speeches to optimize acoustic model by minimizing the root mean square error between human and machine scores. And we also derive an EBW-like algorithm for parameter optimization. The experimental results proved the effectiveness. The cross correlation increases from 0.610 to 0.713 and the root mean square error reduces from 1.930 to 1.685.

How does longitudinal interaction promote second language speech learning? Roles of learner experience and proficiency levels

This study examined how longitudinal interaction impacts the development of second language (L2) oral proficiency in relation to learners' different experience and proficiency levels. Japanese learners of English as a foreign language (EFL) participated in weekly conversation exchanges with native speakers (NSs) in the USA via videoconferencing tools over one academic semester (12 weeks). The participants' spontaneous speech, elicited from a story telling task before and after the treatment, was analysed via a set of linguistic measures. In line with the componential view of L2 oral proficiency and development, our results hinted L2 learners' experience and proficiency levels as a mediating factor for determining the link between interaction and its impact on different dimensions of L2 speech learning. While the longitudinal interaction equally improved the participants' grammatical complexity and articulation rate - a fundamental component for defining L2 oral proficiency - the development of less experienced/proficient learners was observed across a wide range of lexicogrammar and fluency features (lexical appropriateness/richness, grammatical accuracy, pause ratio). It was only more experienced/proficient learners that significantly enhanced phonological accuracies (segmentals, word stress) which are thought to gradually develop in the later stages of L2 speech learning. These findings add another piece of evidence for the differential effects of long-term interaction relative to L2 learners' developmental stages.

The ability to make effective use of technology is becoming increasingly important for prospective language teachers. As a result, many teacher preparation programs include some form of training in computer assisted language learning (CALL). This study focuses on one component of such training, the textbooks used in methods courses, and employs content analysis to investigate how popular methods textbooks discuss CALL. Criteria based on standards for teacher training and the professional CALL literature revealed that overall, the textbooks can serve as a valuable springboard for early training. Based on the coverage of CALL in their methods textbook(s) and the needs of their particular student teachers, methods instructors should expand the discussion of CALL to provide a solid basis for continued professional development. Several key criteria for such well-rounded training are included in this article.

The present research explored the impact of the aural feedback generated by text-to-speech (TTS) on Arabic language learners. A web-based dictation platform was developed for this purpose. It enables the users to have their text read out loud as they write. This aural feedback will enable them to auto detect their mistakes, make the perceived corrections and re-listen again. A study was carried out in two different primary schools to benchmark the effects of the tool on pupils from third, fourth and fifth grades. Overall, the test revealed a significant improvement in the pupils writing skills;the participants were able to locate and correct a high percentage of their mistakes under speech synthesis vocalization. Besides, in order to assess the extent to which the tool remains efficient even when applied to different categories of persons, a longitudinal study is now being launched on the illiterates and students with visual disabilities. Thus far, the first results are surprisingly very promising. Details of the results will be published in another paper.
