The resources required to have humans score extended written response items in English language learner (ELL) contexts has caused automated essay scoring (AES) to emerge as a desired alternative. However, these systems often rely heavily on indirect proxies of writing quality such as word, sentence, and essay lengths because of their strong correlation to scores (Vajjala, 2017). This has led to concern about the validity of the features used to establish the predictive accuracy of AES systems (Attali, 2007; Weigle, 2013). Reliance on construct-irrelevant features in ELL contexts also forfeits the opportunity to provide meaningful diagnostic feedback to test-takers or provide the second language acquisition (SLA) field with real insights (C.-F. E. Chen & Cheng, 2008). This thesis seeks to improve the validity and reliability of an AES system developed for ELL essays by employing a new set of features based on the acquisition order of English negation. Modest improvements were made to a baseline AES system's accuracy, showing the possibility and importance of engineering features relevant to the construct being assessed in ELL essays. In addition to these findings, a novel ordering of the sequence of English negation acquisition not previously described in SLA research emerged.

The purpose of this dissertation was to evaluate the effects of changing body position on the execution of the isometric mid-thigh pull (IMTP). Furthermore, while there is evidence to suggest that there is an effect of familiarization on performance of maximal strength tests, there has been no known research evaluating the effect of learning on the IMTP. The effect of familiarization was assessed by evaluating changes in variables obtained from the IMTP. Subjects did not statistically improve over the five IMTP testing sessions, regardless of the body position used, or if subjects had previous experience with weightlifting derivatives. This may indicate that little familiarization is needed for subjects to perform the IMTP before acute increases due to learning stabilize. When body positions were compared, there were differences in force production whether subjects had or did not have experience with weightlifting movements. The magnitude of difference between body position was affected by weightlifting movement experience; lifters with >6 months experience with weightlifting had larger differences in force production between position. Average muscle activation for a variety of muscles, evaluated with surface EMG, appeared to differ between body positions, although these positions are idiosyncratic to experience level. In particular, lumbar erector spinae activation was higher in the bent position for both groups, which may have implications for low back injury risk.In entirety, it appears that if maximizing force production is the goal, the upright positon is optimal. Furthermore, the differing body positions have meaningfully different effects on how 3 much individual muscles are activated between positions. Lastly, substantial familiarization does not appear to be necessary before subjects perform the IMTP.

Teachers’ Perceptions of Using Positive Behavior Interventions and Supports as Behavioral Interventions in a Pre-K-5 Elementary School: A Phenomenological Study by Meghann E. Roberts-Clawson This qualitative study addresses teacher perceptions of using positive behavior interventions and supports (PBIS) as positive behavioral interventions. This phenomenological study was conducted within a Pre-K-5 elementary school in northwestern North Carolina. In order to collect qualitative data, personal individualized interviews were conducted from a purposeful sample of teachers in the school who have experience implementing more intensive positive behavioral interventions. By analyzing data derived from the interviews and classroom and individualized documentation, the researcher was able to identify themes such as teachers’ perceptions in regards to using PBIS as a behavioral intervention. Themes elaborating on the ways that teachers implement PBIS in their classroom as well as the most consistently used elements of the PBIS framework also emerged from this study. Findings from this study will be useful in helping to implement the PBIS framework to fidelity as well as helping to sustain these practices. This information will be vital in training new teachers that join the staff as well as veteran teachers who are struggling with individual students’ behavior.

The Motion Sensitivity Test (MST) is a clinical protocol designed to measure motion-provoked dizziness during a series of 16 quick changes to head or body positions. The MST has been used as a guide for developing an exercise program for patients with motion-provoked dizziness and as a treatment outcome measure to monitor the effectiveness of vestibular rehabilitation therapy. This study determined validity, test-retest reliability, and interrater reliability of the MST. Fifteen individuals with motion-provoked dizziness and ten control individuals were tested during sessions occurring 90 min and/or 24 hr after baseline testing. The MST was found to be reliable across raters (intraclass correlation coefficient [ICC] = 0.99) and test sessions (ICC = 0.98 and 0.96). Test validity was good. The results indicated that the MST can be used reliably in clinical practice to develop exercise programs for patients with motion-provoked dizziness and to provide evidence of intervention efficacy

This study represents a quasi-replication of Lane et al. (2009) investigation into the psychometric properties of the Primary Intervention Rating Scale (PIRS). This rating scale was designed to assess the social validity of primary to high school level Positive Behavior Support intervention plans completed by academic staff. Lane's results indicated the PIRS was a one- factor measure with strong reliability and structural validity. To substantiate these findings an adapted version of the PIRS was distributed to teachers from one Utah school district.Quantitative data and additional comments were collected from elementary and middle school teachers. The results were computed using a series of statistical analyses including Exploratory and Confirmatory Factor Analysis and Cronbach's Alpha. Teacher comments were used to provide additional feedback and to examine trends. Results confirmed the Lane et al. findings that the PIRS is a one factor measure with strong internal consistency. Results also indicated that the school district's PBS prevention plan was socially valid from the teachers' perspective.

This study analyzed all published research articles examining the relationship between professional community efforts (plc) (used here as a broader category than, but inclusive of, Professional Learning Communities or PLCs) and student academic achievement (SAA) that reported primary research findings published before January 1, 2015. This study specifically identified primary, quantitative studies of SAA that in context are plc, but which may or may not be labeled as such, that were published before January 1, 2015. Analyses examined how many studies of plc and SAA were of a descriptive, correlational, causal comparative, quasi-experimental,or experimental design type, evaluated the internal validity of their findings, and assessed the generalizability of each study based on normative expectations of implementation and study design type. Each of the 57 studies meeting the inclusion criteria were evaluated using a Design and Quality of Implementation Matrix. Findings indicated that none of 57 primary research efforts examining plc and SAA exhibited acceptable levels of generalizability. For articles demonstrating high design and implementation scores, threats to external validity are presented and discussed. Recommendations are provided for improving the generalizability of research in plc.

Involving parents in school-based learning can be difficult for both schools and parents, and more innovative approaches to involving parents are needed. Internet-based programs have the potential to address barriers to parent participation, but more research is needed to determine the effectiveness and social validity of such programs. This study explored the social validity of WhyTry for Parents, an internet-based program for parents of students enrolled in WhyTry, a school-based social and emotional learning program for students in grades K through 12. Eleven elementary, middle, and high schools across the United States participated in the study by inviting parents of WhyTry students to use the WhyTry for Parents curriculum. Whether or not parents utilized the curriculum, they were invited to take a survey about the importance they placed on the program's goals, procedures, and effects, and to give reasons for their level of participation in the program. A total of 836 parents were invited to take part in the study, and 14 parents made up the final sample. Coordinators (n = 10) of the WhyTry program at each school were invited to participate in interviews focused on their perspectives of parent participation rates and the WhyTry for Parents program. Regardless of whether parents utilized the curriculum, they found a high degree of social validity in WhyTry for Parents; however, they suggested that the curriculum be simplified and made more accessible. WhyTry coordinators suggested that low participation rates were due to parent resistance, and that helping parents to understand WhyTry might help overcome this resistance. Parents and coordinators suggested that the curriculum be available by app to improve accessibility. Future research should explore the social validity of WhyTry for Parents from the perspective of educators, who implement the program at the school level. Studying the costs associated with internet-based parent programs for both schools and parents may also be prudent.
