Predicting Math Performance from Raw Large-Scale Educational Assessments Data : A Machine Learning Approach

2016

Large-scale educational assessment studies (LSAs) regularly collect massive amounts of very rich cognitive and contextual data of whole student populations. Currently, LSAs are limited to reporting student proficiencies in the form of plausible values (PVs). PVs are random draws from the posterior distribution of a student’s ability, which is based on the Bayesian approach with the prior distribution modeling the student background within the population and the likelihood test item response using the Rasch model. While PVs have shown to be a reliable estimate for proficiencies of populations, a more comprehensive study of these rich data sets by deploying machine learning algorithms may pro…
