An Integrated Item Response Model for Evaluating Individual Students' Growth in Educational Achievement
Koran, Jennifer - 2009
Measuring continuous change or growth in individual students' academic abilities over time currently uses several statistical models or transformations to move from data representing a student's correct or incorrect responses on individual test items to inferences about the form and quantity of...

A comparison of calibration methods and proficiency estimators for creating IRT vertical scales
Kim, Jungnam - 2007
The main purpose of this study was to construct different vertical scales based on various combinations of calibration methods and proficiency estimators to investigate the impact different choices may have on these properties of the vertical scales that result: grade-to-grade growth,...

The impact of child work on cognitive development: Results from four low to middle income countries
Keane, Michael P.; Krutikova, Sonya; Neal, Timothy - 2018
We study the relationship between child work and cognitive development in four Low and Middle Income Countries. We address a key weakness in the literature by including children's full time-use vector in the analysis, which leads to different findings from previous studies which do not...

An Assessment of The Nonparametric Approach for Evaluating The Fit of Item Response Models
Liang, Tie - 2010
As item response theory (IRT) has developed and is widely applied, investigating the fit of a parametric model becomes … an important part of the measurement process when implementing IRT. The usefulness and successes of IRT applications rely … sufficient evidence before any model application. There is a lack of promising solutions on the detection of model misfit in IRT …

Posterior predictive model checking for multidimensionality in item response theory and Bayesian networks
Levy, Roy - 2006
If data exhibit a dimensional structure more complex than what is assumed, key conditional independence assumptions of the hypothesized model do not hold. The current work pursues posterior predictive model checking, a flexible family of Bayesian model checking procedures, as a tool for...

The impact of child work on cognitive development: Results from four low to middle income countries
Keane, Michael P.; Krutikova, Sonya; Neal, Timothy - 2020
We study the impact of child work on cognitive development in four Low- and Middle-Income Countries. We advance the literature by using cognitive test scores collected regardless of school attendance. We also address a key gap in the literature by controlling for children's complete time...
