Overall patterns of language use variation across oral proficiency levels of 1,243 Japanese EFL learners and 20 native speakers of English using the linguistic features set from Biber (1988) were investigated in this study. The approach combined learner corpora, language processing techniques, visual inspection of descriptive statistics, and multivariate statistical analysis to identify characteristics of learner language use. The largest spoken learner corpus in Japan, the National Institute of Information and Communications Technology Japanese Learner English (NICT JLE) Corpus was used for the analysis. It consists of over one million running words of L2 spoken English with oral proficiency level information. The level of the material in the corpus is approximately equal to a Test of English for International Communication (TOEIC) range of 356 to 921. It also includes data gathered from 20 native speakers who performed identical speaking tasks as the learners. The 58 linguistic features (e.g., grammatical features) were taken from the original list of 67 linguistic features in Biber (1988) to explore the variation of learner language. The following research questions were addressed. First, what linguistic features characterize different oral proficiency levels? Second, to what degree do the language features appearing in the spoken production of high proficiency learners match those of native speakers who perform the same task? Third, is the oral production of Japanese EFL learners rich enough to display the full range of features used by Biber? Grammatical features alone would not be enough to comprehensively distinguish oral proficiency levels, but the results of the study show that various types of grammatical features can be used to describe differences in the levels. First, frequency change patterns (i.e., a rising, a falling, a combination of rising, falling, and a plateauing) across the oral proficiency levels were shown through linguistic features from a wide range of categories: (a) part-of-speech (noun, pronoun it, first person pronoun, demonstrative pronoun, indefinite pronoun, possibility modal, adverb, causative adverb), (b) stance markers (emphatic, hedge, amplifier), (c) reduced forms (contraction, stranded preposition), (d) specialized verb class (private verb), complementation (infinitive), (e) coordination (phrasal coordination), (f) passive (agentless passive), and (g) possibly tense and aspect markers (past tense, perfect aspect). In addition, there is a noticeable gap between native and non-native speakers of English. There are six items that native speakers of English use more frequently than the most advanced learners (perfect aspect, place adverb, pronoun it, stranded preposition, synthetic negation, emphatic) and five items that native speakers use less frequently (past tense, first person pronoun, infinitive, possibility modal, analytic negation). Other linguistic features are used with similar frequency across the levels. What is clear is that the speaking tasks and the time allowed for provided ample opportunity for most of Biber’s features to be used across the levels. The results of this study show that various linguistic features can be used to distinguish different oral proficiency levels, and to distinguish the oral language use of native and non-native speakers of English. / Teaching & Learning

The study examines how an individual's level of fraud detection proficiency (an individual possessing formal fraud education or training, informal fraud training, fraud task-specific experience, and /or fraud-related certifications) impacts their performance on fraud risk assessments and modification of audit plans. Further, it explores which of the fraud detection proficiency dimensions are valuable for auditors in situations of high and low levels of fraud risk and how these characteristics interact with professional skepticism. This, as well as the effectiveness and efficiency of the procedures selected, are addressed using a survey-based scenario where one case is embedded with a financial statement fraud and the other is not. Tobit and ordered logit regression models are used to evaluate a sample of 40 auditors and 10 forensic professionals with varying levels of fraud-related experiences, education, training, and certifications against a benchmark panel. Results demonstrate fraud certifications are effective in fraud risk assessments, are not effective in audit plan modifications, and on average those individuals tend to over-audit. In addition, fraud-related task-specific experience improves audit plan modification effectiveness. Third, including professional skepticism as an interaction is more reflective of the variable's nature, with results supporting interactions with fraud certifications and informal fraud training in the fraud risk assessment model and formal fraud training in the audit plan modifications model. Finally, individuals of higher rank, in addition to those with fraud certifications, are more likely to over-audit, while individuals in the no fraud scenario are more likely to under-audit. This study contributes to the academic literature with regard to a subset of the FJDM proposed by Hammersley (2011) validating professional skepticism as an integral variable in the model, particularly as an interaction variable and with regard to the impacts of fraud certifications and fraud-related task-specific experience. The study also contributes by providing evidence, which indicate lower fraud risk situations are prone to assessing fraud risk less effectively and under-auditing. Finally, this study also contributes a new measure for direct fraud-related experience, which captures more details regarding applicable task-specific experiences. / Ph. D.

This quantitative study explored the interplay among school culture, chronic absenteeism rates for English Learners (ELs), and overall English language proficiency (ELP) progress, as indicated by the WIDA ACCESS for ELLs 2.0 test, in suburban Virginia middle schools. Utilizing the Virginia Framework for Cultural Competency, which encompasses learning environment, pedagogy and practice, community engagement, and self-reflection, the research aimed to determine the relationships among these domains, school culture, and student outcomes. The overarching research question addressed the interaction between school culture, chronic absenteeism rates for ELs, and ELP progress. Supporting questions examined the connections between school culture and ELP progress, the four cultural competency domains and ELP progress, and school culture and chronic absenteeism rates for ELs. Data for school culture ratings were sourced from the Department of Criminal Justice Services' school climate survey. The information on chronic absenteeism rates for ELs and ELP progress came from the Virginia Department of Education School Quality Profile. Analyses employing single and multiple linear regressions were conducted on existing archival data to identify statistical significance and correlations. The study yielded seven significant findings, highlighted three implications for practice, and revealed one policy implication. The findings from this research could assist current and future school leaders in Virginia middle schools by pinpointing specific aspects of school culture that could potentially enhance chronic absenteeism rates and academic progress in ELs. Additionally, division leaders might use these insights to tailor professional development for middle school principals and other educational leaders, emphasizing the critical role of a positive school culture. Furthermore, this study could support broader research efforts asserting the impact of school culture on academic success among ELs, identifying vital cultural elements that influence student achievement irrespective of their absenteeism or academic progress rates. / Doctor of Education / Principals of Virginia middle schools are tasked with ensuring that all students feel welcome in their building, attend school regularly, and make adequate progress.

This study investigates Swedish upper secondary school English teachers’ definitions of oral proficiency, how they rate the importance of oral proficiency, and how they work with promoting pupils’ development of oral proficiency through their teaching. The study used semi-structured interviews with 11 Swedish upper secondary school English teachers. The results showed that the teachers had different views of what constitutes oral proficiency. More specifically, four themes were identified. These were making yourself understood, fluency, extensive vocabulary, and connecting with the receiver. In addition, the results showed that six of the 11 teachers rated the oral skill as one of, or even the most, important language skill, whereas five of the 11 teachers did not. The discrepancies mostly tied to perceived usefulness and Swedish upper secondary school English courses in general. Furthermore, the results showed that teachers had similar methods and strategies for promoting pupils’ development of oral proficiency, mostly tied to creating communicative contexts. Lastly, the results highlighted the importance of feedback since it makes pupils able to visualize their own learning and development. The present study concludes that oral proficiency plays an immensely important role for pupils, both within and outside of school.

In today's globalized world, effective communication and cross-cultural collaboration are essentialfor success, particularly within multicultural teams. This thesis investigates the intricate interplaybetween language proficiency, cross-cultural adaptability, and team performance in the context ofmulticultural teams. Addressing gaps in understanding how language proficiency and crossculturaladaptability impact cross-cultural communication and team performance withinmultinational corporations in Sweden, this study utilizes structured surveys distributed amongemployees in Swedish multinational corporations with at least one year of work experience. Atotal of 117 employees participated in the initial survey distribution, with 103 valid responsesincluded in the final analysis. This study’s findings shed light on the nuanced influence of language proficiency and culturaladaptability on team performance in multicultural settings. While language proficiencydemonstrates a positive correlation with team performance (β=0.247), its impact appears lesspronounced when English, as a second language, becomes the common communication ground.Conversely, cultural adaptability exhibits a strong positive correlation with team performance(β=0.663), highlighting its critical role in navigating the complexities of diverse teams. Thesefindings suggest that in multicultural environments where a shared second language is used,fostering cultural adaptability may be particularly important for maximizing team performance. This research contributes to the understanding of language proficiency and cross-culturaladaptability within multicultural teams, offering insights for optimizing team dynamics andfostering collaboration in diverse work settings. By recognizing the complexities of languageproficiency and its interaction with team dynamics, organizations can enhance their effectivenessin a globalized business environment.

Interpreter services play an integral role in ensuring equity in healthcare for patients with limited English proficiency (LEP), whose language barrier places them at increased risk for healthcare disparities. Even with the growing number of non-English-speaking patients, a sizeable number being Spanish-speaking, and although such training leads to more culturally competent care with better patient outcomes, there is little curricular time during medical school devoted to effectively using interpreters. This study aimed to understand better how medical education prepares future physicians for their encounters with LEP patients and what experiences they would appreciate in their medical training. Temple LKSOM student from the class of 2024-2027 (M1-M4s), were recruited through flyers and educator announcements to participate in three virtual focus groups with a total of 26 participants. Qualitative data analysis resulted in five themes which were: students felt that interpreters were integral to culturally competent care, students who speak another language have the undue burden of interpreting even when not comfortable doing so, students felt that there was not enough training in medical school regarding various types of interpreters, how to reach them or how to use them properly, students are open to doctoring sessions or simulations with non-English speaking standardized patients and interpreters, and the final theme was that there mixed feelings amongst students regarding the desire to have OSCEs with non-English speaking standardized patients and interpreters. / Urban Bioethics

Although the merits of practical work in physics are often questioned, it remains part of physics curricula world-wide. In distance education the incorporation of practical work into the curriculum is considerably complicated by the unique logistics of the setting and the high cost involved. The research reported in this thesis emanated from the need to improve the practical work module for first year physics at the University of South Africa, one of the largest distance education universities in the world. Specifically, the home-based component which, up to the commencement of the research had been entirely text-based, needed to be addressed. To this end it was necessary to identify a valid and attainable set of objectives and to determine the characteristics, abilities and needs of the students in the target group. A survey polling the viewpoints of South African physics lecturers and students about the objectives of practical work was conducted and an extensive student profile comprising a biographic, cognitive and affective component was compiled. Biographically, the target group is unique in the sense that it consists mainly of adult learners, a large percentage of whom study in a second language. The cognitive component of the profile covered aptitude, proficiency in English, mathematics and the integrated science process skills and level of cognitive development, all of which were investigated for possible influence on performance in practical work. On an affective level, students displayed a very positive attitude towards practical work, seated mainly in their need for concrete exploration of the theory. A practical work module structured around an experiential learning cycle adapted to the distance education environment was subsequently designed. The study material developed for the module comprised an interactive study guide on data processing and experimental procedure, a home experiment kit with accompanying workbook and a laboratory manual. From the pilot study forming part of the development process, it was found that students performed significantly better in an assignment based on home-experimentation than in any of the pen- and paper assignments preceding it. Based on the results of the pilot study, a full home experiment kit was designed, evaluated, refined and implemented. / Physics / D.Phil. (Physics)

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.

The purpose of this study has been to examine how Swedish teachers of English encourage the development of students’ oral proficiency in the English language. By interviewing six Swedish teachers of English at upper secondary school, the study addresses which methods are mostly used by the teachers in order to encourage the improvement of students’ oral proficiency. The results of the study indicate that all the teachers tried in different manners to encourage students’ self-confidence, which would help them develop their oral proficiency. Furthermore, it was possible to conclude that the teachers shared the notion that insecurity is detrimental to the development of students’ oral proficiency. Another method that was used by the teachers was allowing students to work in either pair or groups. Even though most teachers used this method, they did point out different things that were important to think about in terms of group work. For the teachers, it was important that the students had fun during oral exercises, and thus, most teachers used different games when conducting oral activities in order to inspire a more relaxed or comfortable environment. The last concept that the teachers talked about was the usage of the target language in the classroom. Here the teachers’ ideas were not in alignment with each other. Some thought that it was good to force the students to use the target language throughout the lessons when communicating, whereas others only believed that students had to communicate orally in the target language during speaking activities. If students were insecure, it did not, according to these teachers, help the students to force them to speak English throughout the lessons. Most of the concepts that were introduced by the teachers were similar to those found in previous studies on Swedish teachers of English. Furthermore, the results of this paper could also be tied to previous research concerning oral development for L2 learners. / Syftet med denna studie har varit att studera hur svenska engelskalärare främjar utvecklingen av elevers muntliga färdigheter i engelska. Genom att intervjua sex svenska engelskalärare på gymnasieskolan undersöker studien vilka metoder som används mest av lärarna för att utveckla elevernas muntliga färdigheter. Resultaten av studien visar att de flesta lärare som intervjuades på olika sätt uppmuntrar elevernas självförtroende, vilket i sin tur hjälper dem att utveckla deras muntliga färdighet. Tanken om att osäkerhet är skadligt för elevers utveckling av muntlig färdighet delades av alla lärare som intervjuades. En annan metod som användes av lärarna var att tillåta elever att arbeta i par eller grupper. Även om de flesta lärare använde den här metoden pekade de på olika saker som var viktiga att tänka på när det gällde grupp- och pararbeten. Nästa metod som lärarna använde berörde inspirerandet av en mer avslappnad eller bekväm miljö som möjliggör utvecklingen av elevers muntliga färdigheter. För lärarna var det viktigt att eleverna hade kul under muntliga övningar, och sålunda använde de flesta lärare olika spel när de utförde muntliga aktiviteter. Det sista konceptet som lärarna talade om var användningen av målspråket i klassrummet. Här var lärarens idéer inte i linje med varandra. Vissa trodde att det var bra att tvinga eleverna att använda målspråket under hela lektionen medan andra inte trodde det hjälpte elevernas utveckling av sitt muntliga språk. Om en student var osäker, hjälpte det inte, enligt dessa lärare, att tvinga studenten att tala engelska under lektionerna. De påpekade dock att eleverna var tvungna att under talaktiviteter och muntliga presentationer interagera på målspråket. De flesta av de koncept som lärarna introducerade liknade dem som hittades i tidigare studier om svenska engelskalärare. Dessutom kan resultaten av denna uppsats kopplas till tidigare forskning kring oral development for L2 learners.

Written and oral material produced by a group of low-achieving learners of English from the 2-year lines of the Swedish upper secondary school was analysed from the perspective of grammatical correctness and communicative ability. The grammatical analysis focussed on the verb phrase and tests included both free production in speech and writing and elicitation tests. Communicative ability was assessed ‘ ‘objectively* ’ by identifying such parameters as fluency, copiousness and span, and “holistically” by using non-expert evaluators.The scores thus obtained were correlated. Grammatical correctness was correlated with communicative ability both in speech and in writing and writing proficiency was correlated with speech proficiency with respect to both grammatical correctness and communicative ability.Our findings are that there is a positive correlation between grammatical correctness and communicative ability. A remarkable finding is that the percentage of correct verb phrases correlates very weakly with communicative ability in written data. In oral data, the correlation is in fact slightly negative. The learner’s competence in grammar is reflected in both his written and oral performance. On the other hand, there is no correlation between communicative ability in writing and communicative ability in speech.The study shows that a working command of a set of syntactic rules is essential for communication. Errors are, however, an integral part of the learning process. The major part of errors are accounted for by the learner’s use of compensatory strategies. Among these low-achievers, communicative ability in conversation is distinct from writing ability. / digitalisering@umu
