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.

Surveying The Soul: Shaping Auto-Criticism With Reflective Arts-Based Inquiry To Assess A Female Doctoral Experience, Monica Fain Rezac

Electronic Theses and Dissertations

This dissertation is an arts-based auto-criticism assessing the author's experience in her doctoral program. It is also perhaps the first dissertation elaborating on a method called auto-criticism, as derived from educational criticism and connoisseurship. The process of inquiry is rooted in arts-based methods of representation and theories of educational criticism and critical theory in the humanities. Philosophical approaches to artwork and the use of it in these methodologies was inspired by the independent arts practices of intuitive artists. The purpose of this project is for the author to develop, articulate, and create a sense of what auto-criticism entails in the …

Critical Consciousness Of Educators: The Development And Psychometric Validation Of A Measure Using Structural Equation Modeling, Melissa Peterson Schneider

Electronic Theses and Dissertations

This study examines a measure of critical consciousness (CC) of educators created by the author, based on the concept of CC as seminally developed by Paulo Freire. A three-factor conceptual model and measurement scale are developed and validated through exploratory and confirmatory factor analyses. Findings and limitations are discussed, as well as implications for the fields of CC measurement and development in educators.

Latent Growth Curve And Latent Change Score Modeling Of Developmental Relationships Between Executive Functioning And Math Achievement In Early Elementary School, Kerry-Ann Lewis Pearcy

Electronic Theses and Dissertations

The current study compared latent growth curve (LGC) models and latent change score (LCS) models capabilities in modeling complex data in a development framework. Using the nationally representative ECLS-K:2011 dataset, LGC and LCS models explored the dynamic relationship between executive function and math achievement. The relationship between the two constructs has been extensively examined but little is understood about their dynamic relationship. The findings of this study indicated LCS to be more robust than LGC in modeling complex data and in examining dynamic relationship. The findings also suggested that one of the two executive functioning tasks, Dimensional Change Card Sort …
