The application of diagnostic classification models (DCMs) in the field of educational measurement is getting more attention in recent years. To make a valid inference from the model, it is important to ensure that the model fits the data. The purpose of the present study was to investigate the performance of the limited information…

Testlets bring several perks in the development and administration of tests, such as 1) the construction of meaningful test items, 2) the avoidance of non-relevant context exposure, 3) the improvement of testing efficiency, and 4) the progression of testlet items requiring higher thinking skills. Thus, the inclusion of testlets in educational…

In the wake of the French Revolution and the failure of subsequent governments to enact humanistic reforms, Schiller observed in frustration that "a great moment has found a little people…" As we emerge from a once-in-a-century pandemic, navigating crisis after crisis amidst uncertainty and instability, it is easy to sympathize with…

Recent research in multidimensional item response theory has introduced within-item interaction effects between latent dimensions in the prediction of item responses. The objective of this study was to extend this research to bifactor models to include an interaction effect between the general and specific latent variables measured by an item.…

The common practice for testing measurement invariance is to constrain parameters to be equal over groups, and then evaluate the model-data fit to reject or fail to reject the restrictive model. Posterior predictive checking (PPC) provides an alternative approach to evaluating model-data discrepancy. This paper explores the utility of PPC in…

In general, newer educational assessments are deemed more demanding challenges than students are currently prepared to face. Two types of factors may contribute to the test scores: (1) factors or dimensions that are of primary interest to the construct or test domain; and, (2) factors or dimensions that are irrelevant to the construct, causing…

The purpose of this qualitative study was to use an Appreciative Inquiry (AI) approach to discover generative instructional and assessment practices of teachers in the language arts classroom at a 5th and 6th grade low socioeconomic public school campus in Texas that earned five distinctions or three consecutive years. The study sought to design a…

The purpose of this research project was to conduct an exploratory analysis of the 2016 Mississippi Statewide Accountability System (MSAS), which is the model by which all public schools in Mississippi are assessed, rated, and ranked, in an attempt to assess whether or not the system is an effective policy tool, especially in relation to the goals…

This simulation study compared the utility of various discrepancy measures within a posterior predictive model checking (PPMC) framework for detecting different types of data-model misfit in multidimensional Bayesian network (BN) models. The investigated conditions were motivated by an applied research program utilizing an operational complex…

The study examined the self-reported understandings of selected 3rd to 12th grade teachers had of assessment and the assessment practices they reported implementing in their classrooms along with evidence extracted from written lesson plans. The literature on classroom assessment supports the idea that teachers who create meaningful assessments,…

The community college baccalaureate and the university-center baccalaureate models are gaining traction in the state of California as alternatives to addressing the need for greater access to baccalaureate degree programs and to increase the baccalaureate-educated workforce. Little is known about the characteristics and factors associated with the…

The importance of subscores in educational and psychological assessments is undeniable. Subscores yield diagnostic information that can be used for determining how each examinee's abilities/skills vary over different content domains. One of the most common criticisms about reporting and using subscores is insufficient reliability of subscores.…

This dissertation proposes two modified cognitive diagnostic models (CDMs), the deterministic, inputs, noisy, "and" gate with hierarchy (DINA-H) model and the deterministic, inputs, noisy, "or" gate with hierarchy (DINO-H) model. Both models incorporate the hierarchical structures of the cognitive skills in the model estimation…

Increased attention on teacher accountability via student achievement gains has brought proposed policy changes which recommend teachers receive performance pay as recognition for effective teaching. In response to growing consensus that teachers' contributions to student learning should be a part of the teacher evaluation process, education…

This research examined the education system at high-poverty schools that had significantly higher student achievement levels as compared to similar schools with lower student achievement levels. A multischool qualitative case study was conducted of the educational systems where there was a significant difference in the scores achieved on the…
