Longitudinal Analysis For Ordinal Data Through Multilevel And Item Response Modeling: Applications To Child Observation Record (Cor), Zijia Li
Theses and Dissertations--Educational, School, and Counseling Psychology
The large proportion of children from low SES backgrounds and the increasing achievement gap between disadvantaged children and their more advantaged peers are beckoning national attention to investment in early childhood education (Reid, Kagan, Hilton, & Potter, 2015). As evidenced in many research studies (e.g., Heckman & Masterov, 2007), early childhood experiences are critical to the development of children. High-quality early learning is necessary for children, especially disadvantaged children, to narrow the school readiness gap and to build a foundation for more advanced academic, social, and cognitive skills. Importantly, high quality assessment tools (i.e., reliability and validity evidence supporting the …
Investigating How Equating Guidelines For Screening And Selecting Common Items Apply When Creating Vertically Scaled Elementary Mathematics Tests, Maria Assunta Hardy
Investigating How Equating Guidelines For Screening And Selecting Common Items Apply When Creating Vertically Scaled Elementary Mathematics Tests, Maria Assunta Hardy
Theses and Dissertations
Guidelines to screen and select common items for vertical scaling have been adopted from equating. Differences between vertical scaling and equating suggest that these guidelines may not apply to vertical scaling in the same way that they apply to equating. For example, in equating the examinee groups are assumed to be randomly equivalent, but in vertical scaling the examinee groups are assumed to possess different levels of proficiency. Equating studies that examined the characteristics of the common-item set stress the importance of careful item selection, particularly when groups differ in ability level. Since in vertical scaling cross-level ability differences are …
The Strength Of Multidimensional Item Response Theory In Exploring Construct Space That Is Multidimensional And Correlated, Steven Gerry Spencer
The Strength Of Multidimensional Item Response Theory In Exploring Construct Space That Is Multidimensional And Correlated, Steven Gerry Spencer
Theses and Dissertations
This dissertation compares the parameter estimates obtained from two item response theory (IRT) models: the 1-PL IRT model and the MC1-PL IRT model. Several scenarios were explored in which both unidimensional and multidimensional item-level and personal-level data were used to generate the item responses. The Monte Carlo simulations mirrored the real-life application of the two correlated dimensions of Necessary Operations and Calculations in the basic mathematics domain. In all scenarios, the MC1-PL IRT model showed greater precision in the recovery of the true underlying item difficulty values and person theta values along each primary dimension as well as along a …
