The current research examines the influence of disciplines, advisors, committees, language, culture, and previous experiences in students' search and selection of dissertation topics, as well as whether and how students react to those influences during this process. Invention has been an area of research for rhetoricians for centuries, but most modern research focuses exclusively on the pre-writing process in first composition classrooms (Young, 1976). The current research collected survey and interview data from second- and third-year Ph.D. students in natural sciences, social sciences, and humanities at a large research university in the United States. 80 second- and third-year Ph.D. students completed an online survey; 11 students and four of their advisors participated in a semi-structured interview. The results demonstrate that the majority of students spent over three months in the selection of dissertation topics, and the humanities students tended to spend longer time in this process than social sciences or humanities students. Additionally, students have much in common in their perception of the criteria they would use in the selection of dissertation topics, and those criteria are similar to what previous researchers (Isaac, Koenigsknecht, Malaney, & Karras, 1989; Kozma, 1997; Sessions, 1971) have identified. However, when it comes to the actual selection experiences, the interviews show that students do not necessarily apply those criteria rationally. Moreover, disciplines appear to have an overarching effect on students' topic selection. Natural sciences advisors appeared to have more direct involvement in students' topic choice than advisors in social sciences or humanities. The linguistic and cultural backgrounds of the eleven doctoral participants were not found influential in their selection of dissertation topics. Finally, although Ph.D. advisors generally have a good understanding of students' academic progress, their knowledge of the students' personal and professional concerns may differ, and the latter knowledge is crucial in their advising on students' dissertation topic choice. The current study suggests invention in the scholar and researcher level is significantly different from that of first-year composition classrooms. The successful invention of dissertation topics is indispensable of the influence of disciplines, programs as well as the intellectual and practical support students can receive.

This simulation study compared the utility of various discrepancy measures within a posterior predictive model checking (PPMC) framework for detecting different types of data-model misfit in multidimensional Bayesian network (BN) models. The investigated conditions were motivated by an applied research program utilizing an operational complex performance assessment within a digital-simulation educational context grounded in theories of cognition and learning. BN models were manipulated along two factors: latent variable dependency structure and number of latent classes. Distributions of posterior predicted p-values (PPP-values) served as the primary outcome measure and were summarized in graphical presentations, by median values across replications, and by proportions of replications in which the PPP-values were extreme. An effect size measure for PPMC was introduced as a supplemental numerical summary to the PPP-value. Consistent with previous PPMC research, all investigated fit functions tended to perform conservatively, but Standardized Generalized Dimensionality Discrepancy Measure (SGDDM), Yen's Q3, and Hierarchy Consistency Index (HCI) only mildly so. Adequate power to detect at least some types of misfit was demonstrated by SGDDM, Q3, HCI, Item Consistency Index (ICI), and to a lesser extent Deviance, while proportion correct (PC), a chi-square-type item-fit measure, Ranked Probability Score (RPS), and Good's Logarithmic Scale (GLS) were powerless across all investigated factors. Bivariate SGDDM and Q3 were found to provide powerful and detailed feedback for all investigated types of misfit.

ABSTRACT The teaching of formulaic sequences (FSs) to improve speech fluency is a time honored tradition in the field of English as a Second Language (ESL). However, recent research seems to indicate that certain discourse markers, specifically transition and personal stance markers, are more useful than other FSs. This study is an attempt to partially replicate (on a very small scale) one of these studies to see if the findings are similar when the standardized test materials are from the Test Of English as a Foreign Language (TOEFL) rather than the International English Language Testing System (IELTS). The hope is that teacher researchers could have access to readily available, standardized assessment materials with which to create their own research studies consisting of a standardized pretest and posttest. Four students of various levels in an Intensive English Program (IEP) were given a practice listening and speaking exam utilizing TOEFL preparation materials found online. The results were analyzed to see if there was a noticeable correlation between the use of the specified discourse markers on the speech portion of the test and the performance of the students on the listening portion of the test. The findings show some discrepancy between the two studies' results. It appears possible to have a high perceived fluency rate and still have a lower overall speaking fluency when taking into account listening comprehension and various other measures.

The measurement of competency in nursing is critical to ensure safe and effective care of patients. This study had two purposes. First, the psychometric characteristics of the Nursing Performance Profile (NPP), an instrument used to measure nursing competency, were evaluated using generalizability theory and a sample of 18 nurses in the Measuring Competency with Simulation (MCWS) Phase I dataset. The relative magnitudes of various error sources and their interactions were estimated in a generalizability study involving a fully crossed, three-facet random design with nurse participants as the object of measurement and scenarios, raters, and items as the three facets. A design corresponding to that of the MCWS Phase I data--involving three scenarios, three raters, and 41 items--showed nurse participants contributed the greatest proportion to total variance (50.00%), followed, in decreasing magnitude, by: rater (19.40%), the two-way participant x scenario interaction (12.93%), and the two-way participant x rater interaction (8.62%). The generalizability (G) coefficient was .65 and the dependability coefficient was .50. In decision study designs minimizing number of scenarios, the desired generalizability coefficients of .70 and .80 were reached at three scenarios with five raters, and five scenarios with nine raters, respectively. In designs minimizing number of raters, G coefficients of .72 and .80 were reached at three raters and five scenarios and four raters and nine scenarios, respectively. A dependability coefficient of .71 was attained with six scenarios and nine raters or seven raters and nine scenarios. Achieving high reliability with designs involving fewer raters may be possible with enhanced rater training to decrease variance components for rater main and interaction effects. The second part of this study involved the design and implementation of a validation process for evidence-based human patient simulation scenarios in assessment of nursing competency. A team of experts validated the new scenario using a modified Delphi technique, involving three rounds of iterative feedback and revisions. In tandem, the psychometric study of the NPP and the development of a validation process for human patient simulation scenarios both advance and encourage best practices for studying the validity of simulation-based assessments.

South Sudanese refugees are among the most vulnerable immigrants to the U.S.. Many have spent years in refugee camps, experienced trauma, lost members of their families and have had minimal or no schooling or literacy prior to their arrival in the U.S. Although most South Sudanese aspire to become U.S. citizens, finally giving them a sense of belonging and participation in a land they can call their own, they constitute a group that faces great challenges in terms of their educational adaptation and English-language learning skills that would lead them to success on the U.S. citizenship examination. This dissertation reports findings from a qualitative research project involving case studies of South Sudanese students in a citizenship preparation program at a South Sudanese refugee community center in Phoenix, Arizona. It focuses on the links between the motivations of students seeking citizenship and the barriers they face in gaining it. Though the South Sudanese refugee students aspiring to become U.S. citizens face many of the same challenges as other immigrant groups, there are some factors that in combination make the participants in this study different from other groups. These include: long periods spent in refugee camps, advanced ages, war trauma, absence of intact families, no schooling or severe disruption from schooling, no first language literacy, and hybridized forms of second languages (e.g. Juba Arabic). This study reports on the motivations students have for seeking citizenship and the challenges they face in attaining it from the perspective of teachers working with those students, community leaders of the South Sudanese community, and particularly the students enrolled in the citizenship program.

ABSTRACT

The absence of the consonant sound /p/ in Libyan Arabic leads Libyan speakers of English to pronounce /p/ as /b/. This study examines how Libyan Arabic speakers distinguish the English /p/ and /b/ in their production of L2 English. The study also examines the effect of the production contexts and the learning environment on two groups of Libyan Arabic speakers' attainment of the English /p/ in the USA and Libya. The study collected voice recordings of word-initial /p/ and /b/ in isolated-words, minimal pairs, and sentences in English from both Libyan Arabic speakers and American English speakers. The study also collected Libyan Arabic stop consonants /b/, /t/, /d/, /k/, and /g/ from the Libyan participants. The voice recording data were collected using the WhatsApp mobile application from all participants and the Libyan Arabic participants were also asked to fill an online survey. Using voice onset time (VOT) as a measurement tool, this study measured the English and Libyan Arabic data through Praat software. The findings show that most Libyan Arabic participants distinguish between /p/ and /b/, but they did not have as high VOT averages as the American participants' /p/. It also reveals that the production context, especially in minimal pairs and sentence contexts, has an effect on their participants' production. However, the learning environment does not have an effect on the Libyan participants' pronunciation of /p/ in this study.

In two separate publications, the average patterns of, and individual differences in, preschoolers' selective attention processes were investigated using a multilevel modeling framework. In Publication 1, using two independent samples (Ns= 42, 75), preschoolers' selective attention towards different types of emotions (both positive and negative) was examined using two eye-tracking tasks. The results showed that, on average, children selectively attended to valenced emotional information more than neutral emotional information. In addition, a majority of children were able to detect the different emotional stimulus among three neutral stimuli during the visual search task. Children were more likely to detect angry than sad emotional expressions among neutral faces; however, no difference was found between detection of angry and happy faces among neutral faces. In Publication 2, the associations of children's anger and sadness proneness to their attention biases towards anger and sad emotional information, respectively, and the relations of these biases to various aspects children's social functioning and adjustment were examined among preschool-aged children (N = 75). Children's predisposition to anger and sadness were shown to be related to attentional biases towards those specific emotions, particularly if children lacked the ability to regulate their attention. Similarly, components of attention regulation played an important role in moderating the associations of biases towards angry information to aggressive behaviors, social competence, and anxiety symptoms. Biases towards sadness were unrelated to maladjustment or social functioning. Findings were discussed in terms of the importance of attention biases and attention regulation as well as the implications of the findings for attention training programs.

Institutions of higher education often tout that they are developing students to become lifelong learners. Evaluative efforts in this area have been presumably hindered by the lack of a uniform conceptualization of lifelong learning. Lifelong learning has been defined from institutional, economic, socio-cultural, and pedagogical perspectives, among others. This study presents the existing operational definitions and theories of lifelong learning in the context of higher education and synthesizes them to propose a unified model of college students' orientation toward lifelong learning. The model theorizes that orientation toward lifelong learning is a latent construct which manifests as students' likelihood to engage in four types of learning activities: formal work-related activities, informal work-related activities, formal personal interest activities, and informal personal interest activities. The Postsecondary Orientation toward Lifelong Learning scale (POLL) was developed and the validity of the resulting score interpretations was examined. The instrument was used to compare potential differences in orientation toward lifelong learning between freshmen and seniors. Exploratory factor analyses of the responses of 138 undergraduate college students in the pilot study data provided tentative support for the factor structure within each type of learning activity. Guttman's <λ>λ2 estimates of the learning activity subscales ranged from .78 to .85. Follow-up confirmatory factor analysis using structural equation modeling did not corroborate support for the hypothesized four-factor model using the main student sample data of 405 undergraduate students. Several alternative reflective factor structures were explored. A two-factor model representing factors for Instructing/Presenting and Reading learning activities produced marginal model-data fit and warrants further investigation. The summed POLL total scores had a relatively strong positive correlation with global interest in learning (.58), moderate positive correlations with civic engagement and participation (.38) and life satisfaction (.29), and a small positive correlation with social desirability (.15). The results of the main study do not provide support for the malleability of postsecondary students' orientation toward lifelong learning, as measured by the summed POLL scores. The difference between freshmen and seniors' average total POLL scores was not statistically significant and was negligible in size.

This study investigated the internal factor structure of the English language development Assessment (ELDA) using confirmatory factor analysis. ELDA is an English language proficiency test developed by a consortium of multiple states and is used to identify and reclassify English language learners in kindergarten to grade 12. Scores on item parcels based on the standards tested from the four domains of reading, writing, listening, and speaking were used for the analyses. Five different factor models were tested: a single factor model, a correlated two-factor model, a correlated four-factor model, a second-order factor model and a bifactor model. The results indicate that the four-factor model, second-order model, and bifactor model fit the data well. The four-factor model hypothesized constructs for reading, writing, listening and speaking. The second-order model hypothesized a second-order English language proficiency factor as well as the four lower-order factors of reading, writing, listening and speaking. The bifactor model hypothesized a general English language proficiency factor as well as the four domain specific factors of reading, writing, listening, and speaking. The Chi-square difference tests indicated that the bifactor model best explains the factor structure of the ELDA. The results from this study are consistent with the findings in the literature about the multifactorial nature of language but differ from the conclusion about the factor structures reported in previous studies. The overall proficiency levels on the ELDA gives more weight to the reading and writing sections of the test than the speaking and listening sections. This study has implications on the rules used for determining proficiency levels and recommends the use of conjunctive scoring where all constructs are weighted equally contrary to current practice.

Few measurement tools provide reliable, valid data on both children's emotional and behavioral engagement in school. The School Liking and Avoidance Questionnaire (SLAQ) is one such self-report measure developed to evaluate a child's degree of engagement in the school setting as it is manifest in a child's school liking and school avoidance. This study evaluated the SLAQ's dimensionality, reliability, and validity. Data were gathered on children from kindergarten through 6th grade (n=396). Participants reported on their school liking and avoidance in the spring of each school year. Scores consistently represented two distinct, yet related subscales (i.e., school liking and school avoidance) that were reliable and stable over time. Validation analyses provided some corroboration of the construct validity of the SLAQ subscales, but evidence of predictive validity was inconsistent with the hypothesized relations (i.e., early report of school liking and school avoidance did not predict later achievement outcomes). In sum, the findings from this study provide some support for the dimensionality, reliability, and validity of the SLAQ and suggest that it can be used for the assessment of young children's behavioral and emotional engagement in school.
