This study investigates the use of authentic subtitled similar task videos (ASSTVs) and their relationship to second language negotiation of meaning and language production among non-native speakers of English in an online task-based language learning (TBLL) environment. Over the course of two weeks, twenty intermediate nonnative speakers (NNSs) of English from the English Language Institute at Texas A&M University engaged in four communicative tasks in pairs using an online TBLL environment designed specifically for this study, and a chat tool in WebCT Vista, a course management system provided by the university. ASSTVs were videotaped and integrated into the online TBLL environment. Participants were divided into two groups, each of which consisted of five dyads, to test the effects of ASSTVs. Five dyads were provided with the ASSTVs and the remaining five dyads were not provided with them before the task completion process. The first section of this study examines the effects of ASSTVs on negotiation of meaning, and the second section examines the effects on language production. The amount of negotiation of meaning was calculated through the negotiation of meaning sequences model developed by Gass and Varonis and revised for online communication by Smith. Language production was investigated in terms of fluency and complexity with regard to lexical and syntactic complexity. A detailed analysis of the data from the chat-scripts showed that NNSs engage in more negotiation of meaning and produce more fluent and lexically diverse language when provided with the ASSTVs than NNSs who were not provided with them. Based on these findings, this study concludes that using ASSTVs in an online TBLL environment is a viable and effective tool for promoting negotiation of meaning and language production in terms of fluency and lexical complexity.

Many students in an allied health program at a Middle Eastern Arab university were experiencing difficulties with courses taught in English, resulting in poor academic achievement, low grade point averages, a high failure rate amongst its first year students, and an adverse impact upon a future skilled and educated work force for the region. Tinto's theory of institutional action for students' success served as the conceptual framework for the inquiry that used a qualitative explanatory case study method to examine the experiences of those students who were facing difficulties with their studies. To address questions about why students were failing and leaving the school and how the institution might remedy this educational problem, the study employed initial and follow-up interviews and reviews of academic records and portfolios of 6 currently enrolled or recently graduated students over age 21, who volunteered to participate. Content and thematic analysis of the collected qualitative data produced findings indicative of lack of college readiness among students and gaps in institutional practices such as remedial methods for the unprepared students. Based on the study findings, a policy recommendation for improving the educational practices was introduced to support building a better educational environment at the school. The positive social change implications of this study are not only limited to establishing programs to support the students' success and improve retention rates at the institution but also may include the establishment of more effective approaches to the reform measures of the educational system in the country.

This study aimed to evaluate the efficacy of a software-administered shaping procedure in guiding English monolinguals to acquire accurate Mandarin pronunciation. A single-subject reversal ABAB design was used to evaluate treatment effects. A purposely-developed algorithm generated an accuracy score defined as the similarity between a participant’s utterance and the target pronunciation. The shaping procedure provided performance-dependent reinforcement, while the control condition provided performance-independent reinforcement at a density yoked to the shaping procedure. A no-feedback condition assessed spontaneous language learning ability prior to treatment. Data were evaluated via visual analysis and complemented with effect size analyses and repeated-measures ANOVAs. There were no overall treatment effects. However, three individuals demonstrated a statistically significant difference between treatment and control. A follow-up study compared shaping to no feedback using a simplified procedure and simpler stimuli. A multiple-baseline design was used. The results showed no treatment effects. Possible contributing factors and directions for future research are discussed.

This study was aimed at giving a scientific answer to the following problem questions, namely, what communication apprehension connotes: whether students in a parallel medium school suffer from communication apprehension; which factors cause communication apprehension in the classroom, and what measures the teacher can take to prevent or overcome communication apprehension in the classroom. To answer these questions, a literature study on communication apprehension was first undertaken. Communication models and the evaluation of such models were investigated. Communication as a phenomenon was also applied to the classroom situation, and the conclusion was reached that interaction is a prerequisite for communication, and, consequently, also for effective teaching. Communication apprehension interferes with the success of the communication process in the classroom, as well as with the teaching-learning process. To delineate communication apprehension more clearly, the causes of communication apprehension and its influence on the teaching-learning situation were also studied. Guidelines for preventing and overcoming communication apprehension were lastly investigated. The empirical study was based on the completion of the PRCA (Personal Report on Communication Apprehension) by students from a parallel medium school in Klerksdorp, namely the Alabama Secondary School. The following results were obtained: • An average communication apprehension of 62,5% for Afrikaans speaking students versus an average of 63,4% for students speaking other languages. • The average percentage of communication apprehension for students whose mother tongue is Afrikaans is quite high, whether they communicate in Afrikaans (60,2%) or English (64,3%). • The average percentage of communication apprehension for students whose mother tongue is other than Afrikaans is quite high, whether they communicate in Afrikaans (66,0%) or English (59,2%). • The average percentage of communication apprehension of girls is somewhat higher than that of boys. • The communication apprehension of the students is the highest when they participate in public debates, and the lowest when they participate in ordinary conversations. • A fear of failure, a lack of confidence, and the teaching style of the teacher are endorsed as possible causes of communication apprehension, while a lack of communication skills is not a major cause. • The responses of the teachers identified guidelines for preventing and overcoming communication apprehension in students, of which some are in line with the literature, and others are new interesting ideas. Research on communication apprehension in parallel medium schools ought to be extended to include students from primary schools as well. The apprehension of all students to communicate in their mother tongue should also be investigated. The high level of communication apprehension in students ought to be investigated with the aim of developing programmes for inhibiting communication apprehension in students. / Thesis (M.Ed.)--Potchefstroom University for Christian Higher Education, 2000

The focus of this empirical study was on the antecedents of resilience among poor, English second-language (ESL) adolescent learners. The reasons why some adolescents in this situation are resilient and others are not, are indicated in this study. Adolescents qualify as being resilient if they are exposed to significant threat to their development, indicating high risk to the individual, and their adaptation to the threat is successful, due to support, resources or intervention. Thirty three resilient and 32 non -resilient poor, ESL adolescent learners were selected to participate in the empirical study. My study was a mixed method study because I made use of quantitative research (a survey questionnaire completed by the 65 selected learners), and qualitative research (semi-structured interviews with two identified resilient learners and a group interview with elders who are knowledgeable about young people in this community). The conclusions of my study emphasise that dynamic interactions between individual attributes, familial support, community resources, and cultural ties empower some adolescents to overcome hardships and be resilient. My findings are supported by literature. My findings cannot be generalised, as the adolescents in my study were all black, South African youth from an impoverished community in the Vaal Triangle. This is an explorative study, and themes that were identified as contributing to resilience in my study, need to be explored in future studies. / Thesis (M.Ed.)--North-West University, Vaal Triangle Campus, 2009.

This study investigated the students&amp / #8217 / and teacher&amp / #8217 / s perception of a web-based learning tool for an English course which was given as a second language at elementary level. The site was used as a supplementary material for 8th grade students in METU College. The researcher developed the site specifically for this study and in the development process internet and database technologies were used.The data were collected from the 22, 8th grade students through a computer attitude scale and a questionnaire, which was developed by the researcher. An interview with the course teacher was conducted. Descriptive statistics, frequency distributions and researcher observation were used to express the results of the study. The results showed that the site was perceived positively by more than half of the students in terms of vocabulary learning through the dictionary and activities page. The site was evaluated by the students and nearly most of the students found the site to be useful in terms of acquiring hearsay through the dictionary and the chat page of the site. More than half of the students perceived the chat environment more suitable for communication than classroom environment. The course teacher evaluated the site to be useful in terms of vocabulary learning, hearsay and online communication.

Learning a second language is, for the most part, a day-in day-out struggle against the mountain of new vocabulary a learner must acquire. Furthermore, since the number of new words to learn is so great, learners must acquire them autonomously. Evidence suggests that for languages with writing systems, native-like vocabulary sizes are only developed through reading widely, and that reading is only fruitful once learners have acquired the core vocabulary required for it to become smooth. Learners of Japanese have an especially high barrier in the form of the Japanese writing system, in particular its use of kanji characters. Recent work on dictionary accessibility has focused on compensating for learner errors in pronouncing unknown words, however much difficulty remains. / This thesis uses the rich visual nature of the Japanese orthography to support the study of vocabulary in several ways. Firstly, it proposes a range of kanji similarity measures and evaluates them over several new data sets, finding that the stroke edit distance and tree edit distance metrics best approximate human judgements. Secondly, it uses stroke edit distance construct a model of kanji misrecognition, which we use as the basis for a new form of kanji search by similarity. Analysing query logs, we find that this new form of search was rapidly adopted by users, indicating its utility. We finally combine kanji confusion and pronunciation models into a new adaptive testing platform, Kanji Tester, modelled after aspects of the Japanese Language Proficiency Test. As the user tests themselves, the system adapts to their error patterns and uses this information to make future tests more difficult. Investigating logs of use, we find a weak positive correlation between ability estimates and time the system has been used. Furthermore, our adaptive models generated questions which were significantly more difficult than their control counterparts. / Overall, these contributions make a concerted effort to improve tools for learner self-study, so that learners can successfully overcome the reading hurdle and propel themselves towards greater proficiency. The data collected from these tools also forms a useful basis for further study of learner error and vocabulary development.
