A Comparison Of Bayesian Estimation Techniques In A Multidimensional Two-Parameter Partial Credit Item Response Model, Peiyan Liu Jan 2019

A Comparison Of Bayesian Estimation Techniques In A Multidimensional Two-Parameter Partial Credit Item Response Model, Peiyan Liu

Electronic Theses and Dissertations

Bayesian estimation methods have shown better performance than the traditional Marginal Maximum Likelihood (MML) estimation method for parameter estimation in relatively simple item response models. However, extant literature is lacking on the investigation of Bayesian parameter estimation approaches for a multidimensional two parameter partial credit (M2PPC) model, therefore this simulation study investigated the performance of two Bayesian Markov Chain Monte Carlo (MCMC) algorithms: Gibbs Sampler and Hamiltonian Monte Carlo-No-U-Turn-Sampler (HMC-NUTS) for M2PPC models' parameter estimation. It compared the estimation accuracy and computing speed in different combinations of situations, including prior choices, test lengths, and the relationships between dimensions.

Restorative Injustice: A Study Of Failed Implementation Of Restorative Practices At An Urban High School, Paul Gerard Cama

Electronic Theses and Dissertations

The restorative justice process utilizes various intervention strategies created by indigenous tribes throughout the world, as an alternative to procedural justice (Zehr, 2002). In modern education, restorative justice was incorporated into the public-school system, where it has evolved into a preemptive measure to combat punitive discipline policies that is often seen as both racially insensitive and detrimental to the learning of students. The purpose of this study was to examine the implementation process of a school based restorative justice program at an urban high school and focused on how these interventions were implemented, what resources were allocated, and how it ...


How Colonization Impacts Identity Through The Generations: A Closer Look At Historical Trauma And Education, Michelle Garcia-Olp Aug 2018

How Colonization Impacts Identity Through The Generations: A Closer Look At Historical Trauma And Education, Michelle Garcia-Olp

Electronic Theses and Dissertations

Through the lived experiences of 26 New Mexicans, this inquiry investigates how colonization impacts identity through the generations, particularly looking at historical trauma and education. The findings demonstrate the importance of decolonizing spaces within educational settings. Furthermore, the findings demonstrate the need for viewing educational systems and spaces through a Tribal Critical Race Theory (TribalCrit) and Indigenous Storywork lens that lead Indigenous students in finding face (one’s identity), finding foundation (one’s greatest potential/full expression) and finding heart (one’s flow with the creator). The lens of TribalCrit enables the creation of a space where Indigenous students are ...

Location Matters: A Geospatial Analysis Of Principal Turnover In The Denver Metropolitan Area, Lorna O. Beckett

Electronic Theses and Dissertations

Research indicates that principals leave their school on average every three years. Additional research is needed to understand factors that are related to principal turnover. In this study I used geographic information systems to examine the geospatial variance between school characteristics, student achievement, and principal turnover in the Denver metropolitan area. I found that principal turnover is an issue in both urban and suburban areas, with suburban areas in the Denver metropolitan area experiencing similar trends in principal turnover. In this study I also highlight the importance of understanding local context when examining principal turnover patterns.


Classification Of One-Year Student Persistence: A Machine Learning Approach, Ben Siebrase Jun 2018

Classification Of One-Year Student Persistence: A Machine Learning Approach, Ben Siebrase

Electronic Theses and Dissertations

Multilayer perceptron neural networks, Gaussian naïve Bayes, and logistic regression classifiers were compared when used to make early predictions regarding oneyear college student persistence. Two iterations of each model were built, utilizing a grid search process within 10-fold cross-validation in order to tune model parameters for optimal performance on the classification metrics F-Beta and F-1. The results of logistic regression, the historically favored approach in the domain, were compared to the alternative approaches of multilayer perceptron and naïve Bayes based primarily on FBeta and F-1 score performance on a hold-out dataset. A single logistic regression model was found to perform ...

Curricular Agency: Contemplating Curriculum As A Process To Empower Teachers, Matthew L. Spurlin Jan 2018

Curricular Agency: Contemplating Curriculum As A Process To Empower Teachers, Matthew L. Spurlin

Electronic Theses and Dissertations

Using the qualitative method of Educational Connoisseurship and Criticism (Eisner, 1991) and an interview structure based on the commonplaces (Schwab, 1969), this study involved working with four exemplary teacher educators to externalize their internal process of curricular decision-making. Contemplating their own curricula as a dynamic process rather than a finished product, the study identifies where in that process their curricular agency—their educational agency, and their human agency (Bandura, 2006)—is found. This operationalization of curricular agency within curricular theory provides an empowering perspective of teacher-centered education as a response to teacher burnout.
