The advantages of administering an adaptive test battery, a collection of multiple adaptive subtests that are specifically tailored to examinees' abilities, include shortening the subtest length and maintaining the accuracy of individual subtest scores. The test battery can incorporate a range of subjects, though this study focused primarily on…

F0 contours convey multiple types of information, including lexical and post-lexical meanings, as well as affective and socio-indexical indicators. This dissertation investigates the interaction between lexical tone and sentence-level intonation in Thai, focusing on how sentence position influences the acoustic realization and perceptual…

This study was conducted to analyze potential item parameter drift (IPD) impact on person ability estimates and classification accuracy when drift affects an examinee sub-group. Using a series of simulations, three factors were manipulated: (a) percentage of IPD items in the CAT exam, (b) percentage of examinees affected by IPD, and (c) item pool…

This three-manuscript dissertation attempts to answer the question: "How does students' English language proficiency (ELP) inform the availability, structure, and use of English language accommodations and intervention to support the academic achievement of English learner (EL) students?" The question is addressed using three independent…

English Language Learners (ELLs) are at an academic disadvantage with the rest of general education because they are linguistically challenged, especially in reading. Educators are recommended to use best practices to provide a good quality education to ELLs through the use of instructional tools. One instructional tool that is recommended to use…

The purpose of this nonexperimental, quantitative study was to determine if there is a significant correlation among teacher-assigned grades (TAG), district checkpoint scores (CP), and student scale-scores on TNReady tests. The focus was on 1,445 seventh and eighth grade students who were enrolled at a middle school in northeast Tennessee during…

With the wide introduction of English-medium instruction (EMI) to higher education institutions throughout East Asian countries, many East Asian universities are using English proficiency tests that were not originally designed for this context to make admissions and placement decisions. To support the use of these tests in this new EMI context,…

Atomic weapons testing during the Cold War and accidents at nuclear power plants have resulted in the release of radioactive fallout over great distances. Little is known about levels of fallout deposited in Indiana. The reported study sampled soil in all 92 Indiana counties to determine the present level of cesium-137 from the 2 to 12 centimeter…

Adult online learners represent the largest demographic in higher education. Academic leaders increasingly use non-designer instructors (NDIs) to meet demands. NDIs have little control over course design, part of teaching presence valued by learners. This quantitative, predictive correlational study investigated (1) to what frequency online…

The purpose of this study was to survey the levels of job satisfaction among full-time faculty members at a selected Mississippi community college using the constructs of Herzberg's Motivation-Hygiene Theory as defined by Wood (1973). The researcher used Wood's 1976 refined Faculty Job Satisfaction/Dissatisfaction Scale to discover the…

The problem addressed in this quantitative experimental study was that students were having more difficulty learning from audiovisual lessons than necessary because educators had eliminated textual references, based on early findings from CLT research. In more recent studies, CLT researchers estimated that long-term memory schemas may be used by…

The present study explored the dimensionality of cognitive structure from two approaches. The first approach used a famous relation between Visual Spatial Working Memory (VSWM) and calculation to demonstrate the multidimensional item response analyses when true dimensions are unknown. The second approach explored the detectability of dimensions by…

The purpose of this study was two-fold. First, this study examined the difference in the State of Texas Assessments of Academic Readiness [STAAR's] academic achievement (Math, Science, Reading and Writing) scores of secondary students by instructional status (Single teaching and Co-teaching).
