The Every Student Succeeds Act of 2015 requires high standards, but academic achievement among English Language Learners (ELL) falls below that of their peers in Texas. These students' lower academic achievement may lead to their dropping out of high school, not going to college, or being underemployed, a problem that led to this study. The purpose of this study was to evaluate whether computer-assisted language learning (CALL) helps ELLs improve their English language proficiency compared to traditional learning approaches. Levy's theoretical framework on the implementation of CALL guided this study. A nonequivalent, pretest-and-posttest design was used to examine mean differences in the increase in proficiency level from the beginning to the end of the year on the Texas English Language Proficiency Assessment System (TELPAS) of ELLS in Grades 3-5 who participated in CALL and of those who did not participate. The sample consisted of 106 English language learners in Grades 3-5: 57 students in the treatment group and 49 in the comparison group. A one-way analysis of variance was conducted to compare language proficiency between the treatment and comparison groups. Results revealed no significant difference in the mean increase in proficiency levels of English language learners between the treatment and comparison groups. Additional analyses of TELPAS subdomains (reading, speaking, listening, and writing) indicated CALL was effective on reading only. Based on the findings, a project study on professional development was designed to focus on instructional strategies to support CALL. This project may lead to social change among administrators and teachers in the methods and strategies they use in the classroom to support CALL and as they work collaboratively to improve language proficiency among English language learners.

A review of the related literature revealed that international students face specific academic challenges. The goal of this research was to investigate the effect of international student peer advising sessions on English as a Second Language (ESL) international students' perceptions of their language skills and strategies for dealing with academic tasks. The research design included a control and an experimental group with a pretest and a posttest administration of the Strategy Inventory for Language Learning (SILL) and the Xu International Student Academic Language Needs Assessment (ISALNA-2) instruments. Qualitative data was also collected. The participants in the study were upper-intermediate level international students in an intensive English program at a large metropolitan university. Scores (n = 23) on the SILL and the ISALNA-2 were used to investigate the changing perspectives of students receiving similar information from different sources, classroom teachers and peer advisors or only classroom teachers. Peer advising sessions were provided to the experimental group of students. The focus of the sessions was advice and direction in language skills (reading, writing, listening, and speaking) for university academic tasks. A split-plot analysis of variance was employed to analyze the quantitative data obtained from pre- and posttest administrations of the instruments. Analysis of the data did not reveal a statistically significant effect of the peer advising sessions as regards the improvement of scores on the SILL and ISALNA-2. Qualitative data (n = 29) indicated that the experimental participants were positively impacted in understanding the necessary language skills necessary for academic success. Interviews with the peer advisors revealed that they had enhanced their understanding of university expectations and had developed a higher level of confidence as a result of their participation in the advising sessions. Qualitative data revealed positive attitudes by the peer advisors in giving language skills information and by the ESL international students involved in receiving that information. The study format could contribute to future studies and may have implications for the development of international peer advising for English language instruction, foreign student orientation programs, host family programs, and programs linking foreign students with American student study partners.

This study explores the challenges faced by high school science learners when they use English language as a medium of instruction in a South African context. Questionnaires were administered and focus group interviews were conducted with both science learners and science educators. Results indicated that learners are challenged in a number of ways when English is used to teach science especially if English is not their home language. Both learners and educators prefer to be taught and teach science respectively in English though ideally learners would like to be taught in their home languages. To overcome these challenges a home language scientific register should be drawn to cater for all learners’ home language, learners should also be proficient in English or language of science instruction. / Science and Technology Education / M.

In der vorliegenden Arbeit wird der für die allgemeine Wissenschaftssprache des Deutschen charakteristische Bereich der figurativen Verben im Rahmen eines gebrauchsbasierten Ansatzes unter Verwendung korpuslinguistischer Methoden empirisch erfasst und beschrieben. Auf der Grundlage dieser Untersuchung wird ein integrativer Ansatz zur Erfassung und Beschreibung zentraler Wortschatzbereiche der allgemeinen Wissenschaftssprache entwickelt. Das so gewonnene integrative Beschreibungsmodell verbindet die Perspektiven bisheriger quantitativ-bestandsbezogener und bedeutungsorientiert-einheitenbezogener Ansätze und bezieht darüber hinaus sowohl formale als auch inhaltlich-funktionale Aspekte als Gliederungsprinzipien für die zu beschreibenden Wortschatzbereiche mit ein. Methodisch zeichnet es sich durch das Ineinandergreifen von korpusgesteuertem und korpusbasiertem Vorgehen aus. Die Ausarbeitung der Komponenten des Beschreibungsmodells wird auf mehreren Ebenen vorgelegt: Diese werden im ersten Kapitel zunächst ausgehend von einer Bestandsaufnahme vorliegender Arbeiten zur Beschreibung allgemein-wissenschaftlichen Wortschatzes formuliert. Im zweiten Kapitel werden sie im Rahmen eines gebrauchsbasierten Modells der Sprachbeschreibung, der Kognitiven Grammatik Langackers, sprachtheoretisch fundiert. Methodisch eingelöst findet sich diese theoretische Fundierung in den korpuslinguistischen Untersuchungen zu figurativen Verben, die Gegenstand der Kapitel drei und vier sind. Im fünften Kapitel werden die dabei gewonnenen Ergebnisse zu einer formbasiert-funktionalen Typologie figurativer Verben zusammengeführt. Kapitel sechs zeigt die mit dem vorgeschlagenen Ansatz verbundenen Transfermöglichkeiten zur Erfassung und Beschreibung anderer Bereiche des allgemein-wissenschaftlichen Wortschatzes auf. Kapitel sieben ordnet den Untersuchungsgegenstand der figurativen Verben und das entwickelte Beschreibungsmodell aus fremdsprachendidaktischer Perspektive ein und skizziert einen Vorschlag zur Vermittlung allgemein-wissenschaftlichen Wortschatzes. / Verbs like ‘ausgehen von’, ‘beziehen auf’ or ‘darstellen’ that contain semantically concrete basic verbs (gehen, ziehen, stellen) form an essential part of German general academic vocabulary, i.e. vocabulary that is used across disciplines. Adopting a corpus linguistic approach, the study develops a comprehensive description of these ‚figurative verbs‘. Based on a data-driven methodology it investigates the properties of this lexis and shows that figurative verbs containing typical recurring forms like -stellen, -führen, -gehen and others are highly relevant from a quantitative point of view. On the basis of the most prominently recurring formal parts, a core inventory of verbs is collected and described with respect to the areas of meaning expressed as well as regarding aspects of polysemy. Based on the empirical study, a model for the identification and description of vocabulary is developed, that integrates the hitherto separated quantitative - inventory based and meaning oriented - unit based perspectives. Moreover, it brings together aspects regarding form and function as means of structuring the vocabulary under description. Methodically, the model builds on a combination of the corpus-driven and the corpus-based approach. The model is elaborated as follows: In Chapter 1, important aspects of description that the model should meet are identified based on a survey of existing work on general academic language. Chapter 2 provides a linguistic foundation within the framework of usage-based language description. In particular, it draws on Langacker’s Cognitive Grammar, from which the concepts of linguistic unit and construal are adopted. Chapters 3 and 4 present the corpus linguistic investigations on figurative verbs. In Chapter 5, the empirical results are brought together in a form- as well as function-based typology of figurative verbs. Chapter 6 synthesizes the findings into a model and shows possibilities of application of the proposed approach to other areas of general academic vocabulary. Finally, Chapter 7 summarizes the results from the perspective of language pedagogy and outlines a proposal for the teaching of general academic vocabulary.

Verschiedene Schulleistungsstudien stellten für Kinder mit nicht-deutscher Familiensprache bereits in der Grundschule substanzielle Disparitäten im Bereich Mathematik fest. Diese Disparitäten führten zu der Frage, ob die verwendeten Testverfahren zu hohe sprachliche Hürden für Kinder mit nicht-deutscher Familiensprache aufweisen und daher nicht ausreichend in der Lage sind, die Kompetenzen dieser Gruppe valide zu erfassen. In dieser kumulativen Arbeit wurde geprüft, inwiefern die sprachliche Komplexität von Mathematikaufgaben in der Grundschule einen benachteiligenden Einfluss auf die Erfassung der Mathematikleistung von Kindern mit nicht-deutscher Familiensprache darstellt. Zunächst wurde geprüft, ob die in nationalen Schulleistungsstudien verwendeten Aufgaben für diese Gruppe differenziell valide sind. Daran anschließend wurde untersucht, ob sich itemspezifische Kompetenznachteile durch die sprachlichen Merkmale der Aufgaben erklären lassen. In der vorliegenden Arbeit konnte gezeigt werden, dass die differenzielle Validität der betrachteten Testverfahren für Kinder mit nicht-deutscher Familiensprache insgesamt gering ausgeprägt ist. Ferner wurde festgestellt, dass sich die einzelnen sprachlichen Merkmale der Aufgaben sowohl spezifisch als auch gemeinsam auf die differenzielle Validität auswirken. Der größte Anteil der itemspezifischen Kompetenznachteile wurde durch mehrere Merkmale gemeinsam aufgeklärt. Eine experimentelle Teilstudie zeigte, dass eine sprachliche Vereinfachung nicht geeignet scheint, um die Kompetenznachteile von Kindern mit nicht-deutscher Familiensprache substanziell zu verringern. Ein Vergleich der Effekte sprachlicher Merkmale von Mathematikaufgaben auf die Mathematikleistungen von Kindern mit nicht-deutscher Familiensprache zwischen der dritten und der vierten Klassenstufe ergab, dass sich die sprachliche Komplexität der Aufgaben vor allem für jüngere Grundschulkinder unabhängig von ihrer Familiensprache benachteiligend auswirkte. / Large-scale assessment studies have repeatedly documented performance disadvantages of language minority students in German elementary schools. The substantial achievement gap has led to concerns regarding the validity of large-scale assessment items for language minority students. It may be the case that these performance differences are, in part, due to high language demands of the test items. These items may selectively disadvantage language minority students in the testing situation. This dissertation project investigated the connection between the academic language demands of mathematics test items and the test performance of monolingual students and language minority students. First, it was investigated whether the test items were differentially valid for language minority students. Moreover, the connection between the differential validity and the linguistic complexity of the test items was tested. The findings indicated that overall, differential validity of the examined tests for language minority students was low. However, the test items’ language demands were related to differential validity. The largest proportion of item-specific performance disadvantages was explained by confounded combinations of several linguistic features. Additionally, unique effects of descriptive, lexical, and grammatical features were identified. An experimental study showed that linguistic simplification did not seem to be a promising method to substantially reduce the performance differences between language minority students and German monolingual students. A comparison of differential effects of mathematics items’ language demands for language minority students over two adjacent grade levels indicated that the impact of academic language demands seemed to depend on grade level rather than on language minority student status. Regardless of their home language, younger students seemed to struggle more with linguistically complex test items than older students.

<p>This study formed part of a larger project that is concerned with the adaptation of a test of cognitive academic language proficiency, the Woodcock Mu&ntilde / oz Language Survey (WMLS). The WMLS has been adapted from English into isiXhosa and the present study is located within the broader study that is concerned with establishing overall equivalence between the two language versions of the WMLS. It was primarily concerned with the Verbal Analogies (VA) scale. Previous research on this scale has demonstrated promising results, but continues to find evidence of some inequivalence. This study aimed to cross-validate previous research on the two language versions of the WMLS and improve on methodological issues by employing matched groups. It drew upon an existing dataset from the larger research project. The study employed a monolingual matched two-group design consisting of 150 mainly English speaking and 149 mainly isiXhosa learners in grades 6 and 7. This study had two sub aims. The first was to investigate item bias by identifying DIF items in the VA scale across the isiXhosa and English by conducting a logistic regression and Mantel-Haenszel procedure. Five items were identified by both techniques as DIF. The second sub aim was to evaluate construct equivalence between the isiXhosa and English versions of the WMLS on the VA scale by conducting a factor analysis on the tests after removal of DIF items. Two factors were requested during the factor analysis. The first factor displayed significant loadings across both language versions and was identified as a stable factor. This was confirmed by the Tucker&rsquo / s Phi and scatter plot. The second factor was stable for the English version but not for the isiXhosa version. The Tucker&rsquo / s phi and scatter plot indicated that this factor is not structurally equivalent across the two language versions</p>

<p>In the majority of the schools in South Africa (SA), learners commence education in English. This English milieu poses a considerable challenge for English second-language speakers. In an attempt to bridge the gap between English as the main medium of instruction and the nine indigenous languages of the country and assist with the implementation of mother-tongue based bilingual education, this study focuses on the cross-validation of a monolingual English test used in the assessment of multilingual or bilingual learners in the South African context. This test, namely the Woodcock Mu&ntilde / oz Language Survey (WMLS), is extensively used in the United States in Additive Bilingual Education in the country. The present study is a substudy of a broader study, in which the original WMLS (American-English version) was adapted into SA English and Xhosa. For this specific sub-study, the researcher was interested in investigating the scalar equivalence of the adapted English version of the Verbal Analogies (VA) subscale of the WMLS across English first-language speakers and Xhosa first-language speakers. This was achieved by utilising differential item functioning (DIF) and construct bias statistical techniques. The Mantel-Haenszel DIF detection method was employed to detect DIF, while construct equivalence was examined by means of exploratory factor analysis (EFA) utilising an a priori two-factor structure. The Tucker&rsquo / s phi coefficient was used to assess the congruence of the construct across the two language groups</p>

This study was an exploration of the relationship between classroom discourse and a high-stakes, standardized test, the Secondary Entrance Assessment (SEA), administered to students in Trinidad in their final elementary school year ("Standard 5"), with scores used to determine placement into secondary school. Classroom discourse was measured as represented in the oral and written language modeled to students by teachers and textbooks, and compared to the written language expectations implicit in the instructions and items on the SEA. Students' SEA scores were analyzed in relation to their teachers' language to determine if achievement was related to exposure to local/non-standard features of Trinidadian English. One outcome of this analysis was the creation of a survey developed to measure teachers' propensity for speaking Trini (Creole/dialect) or Trinidadian Academic English (standard English) in class by having them respond to audio clips. The survey was found to have acceptable reliability and concurrent validity. For the oral language investigation, 13 teachers were recorded as they led their class in one lesson, and an index of Trini usage (number of Trini utterances per 100 words) was calculated for each teacher. This index was used in an HLM model to determine if teachers' language was a predictor of their students' SEA scores. The distribution of the Trini index was positively skewed, M=1.1 and SD=1.25, indicating low usage of Trini. Trini usage was not found to be a significant predictor of students' 2008 SEA scores, but was found to be a significant predictor of the variation in SEA scores when these were aggregated by class. Similarly, there were few instances of Trini features in the examined textbooks. However, on the SEA, the only influence of Trini was the presence of dialect options used as distractors on two "fill in the blank" items, suggesting a mismatch between the features used in instructional language and the language expectations on the exam. In general, the low exposure to local features did not account for students' achievement on the SEA, but was positively related to the consistency of scores within a class. / text
