Preposition Stranding in Heritage Speakers of Brazilian Portuguese

de Lemos, Simone H 26 April 2013 (has links)
Influential bodies of work in language acquisition studies single out heritage bilingualism as a discrete acquisition process within the bilingualism continuum. In regards to the acquisition of WH-/QU- interrogatives containing prepositional phrases (PP), the present study examined whether heritage speakers (HS) of Brazilian Portuguese (BP) produce preposition stranding (P-stranding) constructions in their heritage language, in contrast to monolingual and adult speakers of BP, where prepositions are pied-piped to form the interrogative. Participants were HS of BP born in the USA and in Brazil, monolinguals, and late bilingual adults. The experiment consisted of an elicited production task and a grammaticality judgment task, both carried out in BP and then in English. Results showed that HS born in the USA use P-stranding in QU- interrogatives productively and systematically, in contrast to the other three groups. Moreover, no evidence of protracted acquisition was found in this group. No signs of attrition were detected among bilinguals.

Entering an academic discourse community: A case study of the coping strategies of eleven english as a second language students

Benz, Cheryl 05 August 1996 (has links)
This case study follows eleven non-English speaking students as they adapt to community college, content courses. The three classes examined are required freshman classes--Humanities, Social Environment, and Individual in Transition. In order to cope with the demands of these classes, students must penetrate the academic discourse community and have effective relationships with their instructors and their peers. The results of the study are based on interviews with eleven non-native speaking (NNS) students and their instructors and on an analysis of student writing assignments, course syllabi, and exams. Three general areas are examined: (a) students' first-language (L1) education, (b) the requirements of their content classes, and (c) the affective factors which influence their adaptation process. The case of these students reveals that: 1. Students draw on their L1 education, especially in terms of content, as they cope with the demands of these content classes. 2. In some areas L1 educational experiences interfere with students' ability to adapt. 3. The content classes require students to have well developed reading, writing, oral, and aural skills. 4. Students must use higher level cognitive skills to be successful in content classes. 5. Affective factors play a role in students' success in content classes. The discussion section includes possible implications of this data for college level English as a Second Language courses.

The effects of planning on second language oral performance in Japanese: processes and production

Nakakubo, Takako 01 May 2011 (has links)
For over two decades, studies on task planning and its role in second language learners' oral performance have shown that the opportunity to plan for a task generally improves learners' speech (Ellis, 2005). It has been hypothesized that the opportunity to plan for a task reduces cognitive load during language processing, thus allowing learners to attend to various aspects of language, and that this enhanced attention, in turn, results in more successful task performance. However, one limitation to this task planning research to date it that most studies have examined the effects of planning before task performance, while largely ignoring the effects of planning that occur during task performance (Yuan & Ellis, 2003). Another limitation in planning research is that findings have been based exclusively on external observation and measurement of learners' oral production; we know little about what strategies learners use that may result in higher-quality speech. The participants in this study were intermediate and high-intermediate learners of Japanese. They were divided into experimental groups and performed a narrative task under different task conditions. Participants received a set of pictures and were asked to retell the story in Japanese. To examine the effects of planning on task performance, fluency, complexity, and accuracy in the participants' speech were analyzed. For the analysis of planning strategies, retrospective interviews were given to a group of participants from each planning group immediately after the task performance. The results revealed that there were no significant differences in participants' oral production across planning conditions, except in the area of lexical complexity (participants without a pre-task planning opportunity produced narrative stories with a greater variety of vocabulary than those who planned before the task). A trade-off effect between lexical complexity and accuracy was found when participants planned either before or during the task. Another trade-off effect was found between lexical complexity and fluency for the participants with on-line planning only. The analyses of strategy use showed that second language learners generally selected similar strategies regardless of planning conditions. These results provided important pedagogical implications and suggested useful future research directions.

Improving Head Start Teachers' Concept Development: Long Term Follow-Up of a Training Program and Differences in Program Impact

Lipp, Amanda KR 01 April 2016 (has links)
Children from a low socioeconomic status (SES) home environment are typically exposed to less vocabulary during the first few years of life and experience higher rates of poor school readiness, particularly in emergent literacy skills, when compared to middle-class peers (Bowey, 1995; Hart & Risley, 2003; Whitehurst, 1997). Early childhood education programs designed to expose this group to cognitively challenging utterances have found that low SES children tend to make greater gains in vocabulary development compared to middle-class peers (Justice, Meier, & Walpole, 2005).

LINGUISTIC AND CONCEPTUAL METAPHORS OF ‘HEART’ IN LEARNER CORPORA

Adams, Aurora Mathews 01 January 2017 (has links)
This corpus-based study examined English and Spanish learner language for ‘heart’ metaphors. Gutiérrez Pérez (2008) compared ‘heart’ metaphors across five languages and that study served as a reference framework for the work presented here. This work intended to find evidence of metaphor transfer and/or new metaphor learning in second language writing. Conceptual metaphors (Lakoff and Johnson, 1980) and linguistic or lexical metaphors (Falck, 2012) from both languages were considered in the analysis. This work analyzed ‘heart’ metaphors taken from two learner corpora, the Cambridge Learner Corpus and the Corpus de Aprendices de Español. Results were compared to the findings of Gutiérrez Pérez (2008) to see whether these metaphors typically occur only in English, only in Spanish, or are found in both languages. The results showed evidence of language learners using several kinds of metaphors that do not typically occur in their first language. The aim of this study was to add a new facet to this body of research by examining these phenomena in learner corpora rather than monolingual corpora. Furthermore, this study also examined both second language English and second language Spanish corpora, addressing potential bi-directionality of transfer or conversely, the use of new linguistic forms.

Investigating the development of syntactic complexity in L2 Chinese writing

Pan, Xiaofei 01 May 2018 (has links)
This present study investigates the development of second language (L2) Chinese learners’ writing by 1) subjective ratings of essay quality, 2) a battery of objective measures representing the general syntactic complexity as well as specific syntactic features, and 3) the sources of verb phrase complexity used by learners of different institutional levels. This study first compares the subjective ratings of the essays written by learners across four institutional levels and then uses Cumulative Linked Model to examine the contribution of the objective measures of linguistic features to the essay ratings. This study further identifies a number of sources used by learners to construct complex verb phrases, which is an important contributor of the essay rating, and compares the amount of usages by learners at different institutional levels. The purpose of the study is to better understand L2 Chinese learners’ syntactic development in writing from multi-dimensional perspectives, and to identify the most crucial elements that determine the quality of writing. This study recruits 105 L2 Chinese college learners to write a narrative essay and an argumentative essay according to the prompts. Each of the writing sample is rated by two independent raters according to the holistic ACTFL Proficiency Guidelines, as well as the analytic rubric which was adapted from the ESL Composition Profile for this study. The derivation of syntactic complexity measures was based on the rank scales of lexicogrammar in Systemic Functional Linguistics (Halliday & Matthiessen, 2014), involving 12 features at the levels of clause complex, clause, and verb phrase, some of which represent constructions unique to Chinese. A series of statistical tests, including Kruskal-Wallis tests, Dunn’ tests, Spearman’ correlation tests, and CLM are performed to answer that research questions. The findings show that 1) learners’ overall writing quality measured by holistic and analytic ratings do not show significant differences across the first several academic years; 2) higher-level learners are more heterogeneous in writing ability than lower-level learners; 3) phrasal complexity contributes more to the essay quality than clausal complexity; 4) syntactic complexity features that learners develop fastest hardly overlap with those that contribute most to the essay rating; 5) complex verbal phrases come from 10 different sources and the composition of complex verbal phrases remain stable across the groups; and 6) essay types makes significant differences in terms of holistic and analytic ratings, use of syntactic complexity features, as well as their contribution to the essay ratings. From the pedagogical view, this study points out that instruction should focus more on complexity at the phrasal level, especially nominalization and complex verb phrases, that play a more important role to determine the writing quality. Some of the current focus in instruction may not necessarily lead to better quality or higher proficiency in Chinese writing.

The acquisition of Chinese connectives by second language learners

Lu, Yuan 01 May 2017 (has links)
This study investigates the acquisition of Chinese connectives by second language learners under the theoretical framework of usage-based theory. Language is not a random set of words and phrases, but rather a coherent and cohesive set of utterances. As such, learning a second language (L2) entails, among other processes, learners’ development of employing cohesive devices to construct a coherent discourse in their target language. One type of cohesive devices frequently used by L2 learners is connectives. In Chinese, connectives are utilized to denote various semantic relationships between the clauses in a compound sentence. Due to their flexibility and complexity in nature, Chinese connectives present a huge challenge to L2 learners’ learning. However, to date no study has been set up to explore the learners’ development of Chinese connectives within L2 Chinese research community. This study aims to fill this gap in the literature and build an L2 acquisitional model of Chinese connectives under the theoretical framework of Constructionist Usage-based Theory. Constructionist Usage-based Theory maintains that the basic unit of language is constructions and that the syntactic and lexical form of constructions and its corresponding semantic and discourse functions are conventionalized in language usage. According to these notions, language learning is believed to be driven by the factors grounded in the form and function of constructions in language usage. This study specifically examines how the factors of frequency, form, function, contingency (interaction of form and function), and L1-tuned attention affect L2 Chinese learners’ development of Chinese connectives. Furthermore, the study investigates the learners’ knowledge about the distribution of Chinese connectives across different proficiency levels. Specifically, this study aims to address four research questions: (1) what is the relationship between L2 learners’ proficiency level and language background and the acquisition of Chinese connectives?; (2) do L2 learners overuse or underuse Chinese connectives in constructing responses when the other in a pair is given and what errors do L2 learners make when using Chinese connectives?; (3) how can 12 target pairs of Chinese connectives be categorized into (hierarchical) groups based on L2 Chinese learners’ performance?; and (4) how do theoretically-motivated models represent the factorial structure underlying L2 acquisition of Chinese connectives? To address the four research questions, this study elicited L2 Chinese learners’ performance in two tests: a mini-discourse completion test and a form-function association test. In the mini-discourse completion test, learners were required to supply a missing clause to complete a three-clause discourse in which one of paired connectives was embedded; in the form-function association test, learners were asked to choose options of paired connectives to link two given clauses where connectives were omitted. Results showed that the development of all Chinese paired connectives was positively correlated to L2 learners’ L2 proficiency level. Learners with heritage language background seemed to have an advantage over less frequent and less prototypical connectives. Predominantly, L2 learners underused Chinese connectives, resulting from the cross-linguistic influence of disparity between English and Chinese connectives at the structural level in particular and between English and Chinese textual cohesion at the discourse level in general. Based on L2 learners’ performances in the two tests, the 12 pairs of Chinese connectives were classifier into four hierarchical groups. Confirmatory factor analyses showed that the usage-based factors (i.e., frequency, co-occurrence strength, formulaicity, prototypicality, contingency, and L1-tuned attention) jointly determined the L2 acquisition and development of Chinese connectives in a complex, adaptive, dynamic manner. Summarizing these findings, this study proposed a usage-based acquisitional model of L2 Chinese connectives, providing theoretical contributions to the usage-based theory and pedagogical implications for Chinese connectives.

Maximizing communication for learning in an upper-division literature and culture course

Rose, Céline G. 01 December 2018 (has links)
Several researchers (e.g., Allen & Paesani, 2010; Maxim, 2009; MLA Report, 2007) argue that the language-literature divide limits language development in many foreign language departments and that the speaking skill is the most affected by this common two-tiered curriculum (Swender, 2003). This study investigates the implementation of the concept of collaborative dialogues in an upper-division Francophone literature and culture course to support the oral proficiency skills of the participants. It addresses research questions pertaining to (1) how they constructed their group conversations in terms of language and content, (2) the connections between their dialogues and whole-class discussions, and (3) their perspectives about their group conversations. Both whole-class discussions and weekly group dialogues, which took place outside of class, were video-recorded. The participants took an oral proficiency test at the beginning and at the end of the study and shared their opinions about the dialogues in two questionnaires and in stimulated recalls. The analysis of the data sources shows that the majority of participants focused heavily on content during their conversations. This finding differs from previous research on collaborative dialogues, which hosted many interactions about language and supported language learning. Based on their analytical abilities and proficiency levels, the participants of this study either reviewed previous class discussions or extended them by exploring additional material and adding prior knowledge to their arguments. Extending class discussions during outside-of-class dialogues was a scaffolding activity which better prepared the participants to contribute to subsequent class discussions. Questionnaires and stimulated recalls suggest that the participants enjoyed participating in weekly group conversations because it supported their comprehension of difficult class concepts and materials and helped them develop confidence speaking.

Investigating effects of computer-based grammar tutorials

Kolesnikova, Anna 01 July 2011 (has links)
This dissertation study examined a broad question of whether computer-based grammar tutorials are effective and welcome tools to review grammar for language learners by investigating effects of three different modes of such tutorials on learners' knowledge and satisfaction. For this study, I developed experimental tutorials in three different modes (a static text with a voice-over narration, an animated text with a voice-over narration, and a recording of a real teacher) for two target structures of German grammar (regular verb conjugation and separable-prefix verbs). In total, there were more than 100 Elementary German students at two Midwestern universities, who participated in different stages of the study. The participants represented a mostly homogeneous group with characteristics that are common for college-level learners. There were two parallel experiments in this study that employed identical methods but focused on two different target structures. Thus, both experiments examined the effect of the three study tutorials on learners' knowledge and satisfaction, but Experiment 1 focused on the regular verb conjugation, whereas Experiment 2 focused on the separable-prefix verbs. For each experiment, the participants completed a pretest, worked with the assigned tutorial mode, completed a posttest, and filled out a number of questionnaires. The results of the analysis demonstrated that the study tutorials helped learners to significantly improve their knowledge of grammar; however, the mode of the tutorial did not make a difference. Likewise, all modes of tutorial received similar satisfaction ratings; however, additional qualitative analysis suggested that a considerable number of the participants preferred the animated mode. The findings of the study demonstrate that computer-based grammar tutorials can be effective and welcome tools to review grammar for language learners. Moreover, tutorials of this type can be a viable method of achieving the desired balance between the form- and meaning-focused activities in language classrooms. Also, such tutorials appeal to learners because they support more individualized learning.
