Inferential Procedures For Dominance Analysis Measures In Multiple Regression, Shuwen Tang

Theses and Dissertations

In order to better interpret a selected multiple regression model, researchers are often interested in whether a predictor is significantly more important than another or not. This study investigates the performance of the Normal-Theory based (asymptotic) confidence interval and bootstrap confidence intervals for predictors' dominance relationships using both normal and non-normal data. The results show that asymptotic confidence interval method is adequate to make inferences for comparing two general dominance measures when the distribution is multivariate normal or slightly non-normal and when the effect size is no less than 0.15 and the sample size is at least 100. However, the …

A Desk Study Of The Education Policy Implications Of Using Data From Multiple Sources: Example Of Primary School Teacher Supply And Demand In Malawi, Moses Khombe

Theses and Dissertations

Malawi, as a country with very limited resources, needs to have educational policies in place to maximize effectiveness of the public education system. Policymakers depend on accurate data, but variations in data between sources leaves policymakers uncertain as they attempt to craft policies to address the growing educational crisis in Malawi. A desk study was performed to evaluate the policy implications of employing data from multiple sources using primary school teacher supply and demand in Malawi as an illustration. This study examined one national organization, Malawi's Ministry of Education, Science, and Technology (MoEST); three international aid and assistance organizations (IAAOs), …

Assessing Mathematical Competence In Second Language: Exploring Dif Evidences From Pisa Malaysian Data, Mazlina Husin

Theses and Dissertations

The year 2003 represents a significant milestone in the history of education development in Malaysia. From 2003, mathematics and science will be taught in English. This change in policy was deemed necessary to ensure that Malaysians are able to keep abreast with scientific and technological development that is mostly recorded in the English language. However, an unintended consequence of this language change was its huge impact on the national education system and the assessment of that system as well. Whenever students are not tested in their home language, one validity issue arises, which is how language, rather than the targeted …

Dif Analyses In Multilevel Data: Identification And Effects On Ability Estimates, Yao Wen

Theses and Dissertations

Fairness is an important issue in educational testing in that different groups of examinees should have equal probabilities of answering an item correctly, provided they have the same capabilities. Therefore, differential item functioning (DIF) analyses were developed due to the possibility of bias in cognitive or achievement tests. Data are multilevel structured in educational testing as students are nested within teachers who are nested within schools, and which may further be nested within districts. Although DIF analyses have been discussed for decades, they are rarely investigated in multilevel data. In this study, DIF analyses in multilevel data were investigated via …

Validity And Rater Reliability Of Peer And Self Assessments For Urban Middle School Students, Lucas Jackson

Theses and Dissertations

This project studied the validity and reliability of self and peer assessments used for group work. The targeted population is middle school students in urban schools. The sample includes 45 sixth graders selected from a public middle school in a large Midwestern metropolitan area. The students worked in groups to complete a classroom project. Self and peer assessment forms were used to rate each member's contribution to the group work. A Generalizability Theory design was used to evaluate the reliability of self and peer assessments. The validity of student ratings was assessed by comparing them to those assigned by the …

An Analysis Of Program Evaluation In Community College Learning Assistance Centers, Doug Franklin

Theses and Dissertations

Learning assistance centers exist in varied formats at many colleges and provide services to support the educational mission such as tutoring, support for special needs students, study skills instruction, writing or math instruction. This study seeks to add to the small body of research on evaluation measures used within learning assistance centers and the program evaluation practices of such centers by determining the prevalence of program evaluation and what measures learning assistance directors perceive they should be using in the evaluation of their program compared to those actually being used?

Learning assistance center directors at 61 public two-year institutions, out …

Essentially Point-Less: The Influence Of Alternative, Non Points-Based Grading On Teachers' Instructional Practices, Jay C. Percell

Theses and Dissertations

Grading is often a time-consuming, laborious task for teachers continuously required to document student performance. Simultaneously, among students there is intense competition for grades, which determine class ranks, college entrances, scholarship opportunities, as well as satisfy parental and societal expectations (Campbell, 2012; Wood, 1994). Due to the importance of grades, some educators have sought to determine whether or not traditional grading systems are truly indicative of students' abilities (Brookhart, 1991, 1993; Guskey, Swan & Jung, 2011).

This study investigated alternative grading systems, especially those that were non points-based, and the influence alternative grading had upon teachers' instructional practices. This study …

Assessment For Learning: An Evaluation Of A Professional, Aimee Davis Feehery

Theses and Dissertations

The purpose of this program evaluation was to determine how teachers have come to understand, use, and value formative assessment through their participation in our Assessment for Learning Teams for the past five years. Greeno, Collins, & Resnick's (1996) learning theory serves as the theoretical framework of the evaluation, as this program evaluation serves to determine if, and how, teachers have changed their mental models of assessment from a Behaviorist-Differentiationist model to the Cognitive-Situative model, or from an Assessment of Learning view of assessment, to an Assessment for Learning perspective. In order to determine if teachers have gained the conceptual …

(Re)Envisioning Placement For 21st Century Writing Programs, Jessica Nastal-Dema

Theses and Dissertations

Writing assessment has continued to gain prominence within educational settings and public discourse in the United States throughout the past century. Placement into First-Year Writing, however, is consistently ignored in the scholarly literature, despite its central role within writing assessment and the university. This dissertation argues that placement is central to all students' university experiences, and deserves more attention. Placement is at the heart of composition: it affects each student, each instructor, each writing program, each institution. It significantly influences retention, instruction, budget, and even national reputation, since student retention and graduation rates are key factors in national rankings such …

Food Landscapes: A Case Study Of A Cooking And Art- Focused Program For Teens Living In A Food Desert, Jessica R. Norris

Theses and Dissertations

This study constructs themes and propositions about the experiences of youth participants in the fall 2013 Food Landscapes program at the Neighborhood Resource Center in Richmond, Virginia. During the program, youth participated in cooking-based volunteerism with adults with disabilities and created short videos about their experiences. In this study, I analyzed pre- and post-program participant interviews, twice-weekly program observations, and facilitator reflections to understand how Food Landscapes affected youths’ conception of community engagement and communication strategies. This case study offers insight into how youth experience after-school programming of this design. Based on my findings, youth develop and rely upon a …
