ItemApplications of item response theory to identify and correct for suspect rater data( 2006)This thesis describes a plausible values imputation approach for deriving population estimates on several language proficiency domains. The approach harnessed a multi-dimensional item response analysis combining student responses, rater judgements and student background variables. The target student population was lower grade primary school students enrolled in the Hong Kong schooling system. The raters consisted of local teachers of English employed within the sampled target schools. The primary objective of this research was to impute plausible values where no data was provided or where rater data was deemed suspect. By necessity, a secondary objective of this study was to establish rules for justly excluding particular data on the basis of questionable validity. Surveys such as TIMSS, PISA and NAEP have used such "plausible value" methodologies to account for incomplete test designs and person non-response (Beaton & Johnson, 1990; Yamamoto & Kulick, 2000; Adams & Wu, 2002). The point of difference between this study and other similar studies was the use of item response theory (in particular plausible values imputation) to identify and correct for invalid rater judgements in a large-scale educational survey. An additional research outcome included a derived index of rater data quality based upon imputation scores.

ItemLearner access to language research( 2008)This is a study of how my class of learners perceived the relationships between English language learners, teachers, and researchers, during a five week Intensive Academic Preparation ELICOS course at an Australian university. As a starting point, it seizes on the fact that learners, unlike teachers and researchers, are rarely, if ever, encouraged to engage with language research as a potentially valuable resource for language learning. Noting the dearth of literature surrounding this topic specifically, this study focuses on the appropriateness of various practitioner inquiry models for a naturalistic exploration of my own classroom. The approach taken is one of Exploratory Practice, which is a set of guiding principles motivated by a strong ethicality towards learners and teachers. Using everyday pedagogical activities as data collection methods, such as group discussions and summaries as well as individual written pieces, this study reveals three important characteristics of my learners: a sense of pride in their personal knowledge of English language learning, an understanding of themselves as individuals within the language learning process, and a deep concern with the practical aspects of learning English. Meanwhile, my learners generally portray the relationships between learners, teachers, and researchers as hierarchical and unidirectional, with researchers and research on top. Overall, the study suggests that there is some value in providing access for my learners to language research, and in the conclusion to the study I make some recommendations for future research centring around ideas of learner identity, teacher/learner understandings of roles, and the place of the individual language learner within language learning.

ItemInteractions between literacy in Korean and English in Korean immigrant children in Australia( 2008)Previous research has found that literacy skills, knowledge and strategies transfer across languages, and a strong establishment in one language facilitates development of a second language. This research is ultimately concerned with the interactions between literacy in different language contexts - Korean and English. That is, the research explored how bilingual children's literacy in the first language (Korean) affects the acquisition of a second language (English). To accomplish this objective, this study investigated the strategies that Korean bilingual children use for reading and writing in Korean script and whether these strategies have a positive or negative transfer to English. This research also exposed the reading and writing behaviours, and attitude towards the two languages and how they affect the transfer of literacy skills and strategies. The study was based on the qualitative case-study method with some additional quantitative measures, in search for in-depth understanding about bilingual children's language acquisition and development. The subjects for this project consisted of three Korean immigrant children aged eight to ten for the purposes of comparison. This research asked them to display their literacy experiences in both languages and their attitudes. The main precise method for reading was the running-records technique, which tests contextual reading accuracy and strategy use during which children read the appropriately leveled texts. Whether the texts are appropriate is decided by the error rate that is simply estimated by the number of words read incorrectly to the total number of words read. Reading data was analysed though the running records coding scheme and conventions. A running record was suitable for the research in terms of helping assess children's reading ability, and capture various reading behaviours and strategies use, based on the children's errors and self-corrections. To look into the writing process, think-aloud protocols were employed. This is defined as verbalising thought processes while reading or writing. Children's introspective verbal reports were coded and analysed through Arndt's (1990) modified version of the coding scheme developed by Perl (1981). The method helped the researcher discover the writing processes and interactions between the first and second languages. Discussion centred on the transferable strategies and the relationship between Korean and English reading and writing. The result was that the reading and writing behaviours and strategies that the children displayed were consistent across languages. All in all, this research provided a better understanding of Korean English bilingual children's biliteracy development. The research concluded that a positive transfer of strategies occurred from Korean to English, and accordingly Korean literacy had a positive effect on English literacy development.

ItemA case study of Japanese students: e-mail exchange in English: feedback focusing on communicability( 2007)English education in Japan has been struggling to improve the communicative proficiency of students. Previous studies reveal that low motivation, a lack of confidence in using English and few opportunities to use English for communication are the factors that inhibit the communicative proficiency of Japanese students. Although writing has been gaining significance in communication in English in the era of the Internet, writing has been an area disregarded among the communication skills in classrooms in Japan. This study explores ways to improve Japanese students' motivation and confidence through writing by setting e-mail exchanges for Japanese students with Australian native English speakers. A discrepancy exists between the goal of writing and the feedback provided to students' written work in English classrooms in Japan. Great attention is still paid only to the grammatical accuracy while communication is emphasized as the goal of English learning. Excessive attention to grammatical accuracy is one of the factors inhibiting Japanese students in improving their confidence and motivation for learning English. In order to change that situation, this study compares specific feedback focusing on 'communicability', the intelligibility of writing for readers with the traditional error correction technique. The error correction type feedback has been shown to have a negative influence on students' motivation and confidence, and consequently their attitude towards English learning. On the other hand, the feedback focusing on communicability is found effective in improving students' motivation, confidence in English and attitude towards English learning. E-mail exchange has also been found to be effective in enhancing students' motivation. The study recommends incorporating e-mail writing and the feedback focusing on communicability into English classrooms in Japan. These can be positive means of improving students' communicative proficiency and willingness to communicate in English.

ItemA case study of the implementation process of an immersion program( 2006)This project aims to investigate the factors and strategies for implementing an immersion program through a case study conducted at a private school in Melbourne (School "M"); to suggest practical steps for the implementation process of an immersion program and some effective implementation strategies. Furthermore, findings from the case study may contribute to the implementation process of an immersion program in the Korean context. Rigor in this research derives from the triangulation of data, the interpretation of perceptions, and rich description. Firstly, two questionnaires were employed to collect data about the attitudes of both parents and teachers towards the immersion program. Secondly� observations of the meetings of "the Bilingual Committee" in the school were used to collect data about steps and strategies of the implementation process. Thirdly, interviews of participants of "the Bilingual Committee" were analysed to ascertain the topics discussed and the decisions taken. Findings from data analysis were presented as four steps in the implementation process and three strategies for the implementation. Recommendations for School "M" and the Korean context were suggested in order to improve the implementation process of an immersion program.

ItemFrom EAP to university: a case study of Chinese students in Melbourne( 2006)Using qualitative research methods, this thesis examines the experiences of four international students from Mainland China during their transition from language study to tertiary study in Melbourne in 2005. The study explores, through the narratives of students, language teachers and university tutors, the challenges of providing tertiary , level education to students whose cultural and educational background is significantly different to that in Australia. The research is set within the context of the declining government funding to Australian universities and their consequent reliance on full fee paying international students. The student participants in the study attended a private language centre which provides English for Academic Purposes (EAP) courses through its English Language Intensive Courses for Overseas Students (ELICOS) programs, followed by enrolment in the business faculty of a large university. The issues that were identified are analysed following a narrative approach. The study found that the students were not receiving a positive educational experience and identified some of the difficulties they had in adapting to the demands of the Australian higher education system. These included the impact of the differences in teaching and learning approaches, level of English language skills, lack of prior education in the discipline, segregation, isolation and lack of support. The significant issues raised by the university tutors' included international students' inadequate language skills, mismatch of expectations, plagiarism, entry requirements, the changing face of the university, and lack of support. � The study concludes with the implications of international students not receiving a positive Australian educational experience and some recommendations for strengthening the Australian higher education system.
