Utility Of The Causal Inference Approach To Mediation Analysis With Binary Outcomes, Anh Thu Le

Education Policy and Leadership Theses and Dissertations

This dissertation is methodological research to inform educational researchers that the causal inference approach will produce a more accurate estimate of a mediation effect. The effect will help researchers make important and accurate decisions such as changing teaching curricula or implementing interventions.

Evaluation Of The Utility Of Informative Priors In Bayesian Structural Equation Modeling With Small Samples, Hao Ma

Education Policy and Leadership Theses and Dissertations

The estimation of parameters in structural equation modeling (SEM) has been primarily based on the maximum likelihood estimator (MLE) and relies on large sample asymptotic theory. Consequently, the results of the SEM analyses with small samples may not be as satisfactory as expected. In contrast, informative priors typically do not require a large sample, and they may be helpful for improving the quality of estimates in the SEM models with small samples. However, the role of informative priors in the Bayesian SEM has not been thoroughly studied to date. Given the limited body of evidence, specifying effective informative priors remains …

Examining Three Approaches To Supporting English Learners By Leveraging Technology, Jillian Conry

Teaching and Learning Theses and Dissertations

This three-article dissertation examines three distinct approaches to supporting English learners (ELs) by leveraging technology. Framed by the third generation of cultural-historical activity theory (Engeström, 1987; 2001), this research illuminates ways different stakeholder groups within varying activity systems support ELs, by examining technology as 1) an instructional tool in the classroom, 2) a mechanism for family engagement, and 3) a means for preparing teachers to serve ELs. Types of technologies implemented in these studies include various online multimodal tools (e.g., VoiceThread, Zaption), learning management systems (e.g., EdModo, Canvas), social media platforms (e.g., Facebook, Twitter), and mixed-reality simulation (MRS; e.g., Mursion). …

Examining The Consequential Validity Of Using An English Language Proficiency Assessment For Reclassification Decisions, Anthony Sparks

Teaching and Learning Theses and Dissertations

The purpose of the current study is to develop a better understanding of reclassification decisions for English learners. Previous research has primarily viewed reclassification strictly through a policy lens without providing a framework for understanding these high-stakes decisions. However, I adopt a validity framework for reclassification decisions, specifically as a consequence of testing. The framework specifies that assessment uses, such as reclassification decisions, have consequences that need to be understood. Furthermore, I conduct analyses of both achievement data and data related to graduation and college readiness to fully understand the impact of reclassification decisions. The Duke Center for Child and …

Tidying And Analysis Of The 2014 Texas English Ii End-Of-Course Exam, David Churchman, Abigail Morton Garland

SMU Data Science Review

The state of Texas requires all public high school students to take End of Course (EOC) exams. The results of these exams are made nominally public, but in a shape and format that precludes ready analysis. To the extent possible, principles of tidy data will be applied to clean and analyze the publicly released data file for the 2014 English II EOC exam, providing insights into the EOC program and a case for better public data from the Texas Education Administration (TEA).

Geo-Spatial Mapping As A Catalyst For Creative And Engaged Design In Engineering Education, Jessie Zarazaga

Multidisciplinary Studies Theses and Dissertations

Exploiting the technology of geo-spatial mapping student designers can develop deep understandings of the rich and layered data of a spatial context, a situational understanding essential to responsible civic design. However the actions inherent in the construction of spatial data armatures can simultaneously be harnessed as creative strategies, in which mapping processes become the context for generative spatial play. The ambition of this study is to propose efficient pedagogic structures to help prepare civil and environmental student engineers to be not only strong participants, but leaders, in the design of the built environment. The interpretation of site data, mapped as …

The Impact Of Information Literacy Instruction On Student Success: A Multi-Institutional Investigation And Analysis, Joni Blake, Melissa Bowles-Terry, N. Shirlene Pearson, Zoltan Szentkiralyi

Fondren Library Research

The GWLA Student Learning Outcomes task force analyzed the data from over 42,000 first-time, first-year freshmen and over 1700 distinct courses from 12 research institutions to determine the impact(s) of information literacy instruction integrated into course curriculum on several student success measures.

Key findings include:

• Student retention rates are higher for those students whose courses include an information literacy instruction component.
• On average, First-Year GPA for students whose courses included information literacy instruction was higher than the GPA of students whose courses did not.
• Students exposed to library instruction interactions successfully completed 1.8 more credit hours per year than their …
