Title: Detection of Learning in Cognitive Diagnosis
Author(s): Jeff Douglas*
Companies: University of Illinois
Keywords: change point detection ; latent class ; CUSUM ; cognitive diagnosis
Abstract:

The problem of learning in cognitive diagnosis is considered. A natural direction for cognitive diagnosis modeling to move towards is the study of learning and skill acquisition. Borrowing from the statistical literature on change-point detection, we propose sequential change detection procedures for identifying when learning has occurred. By quickly identifying this moment while also controlling for false detection rates, one may efficiently time the introduction of nonmastered skills with an ultimate aim of assisting a student in acquiring the entire set of skills as quickly as possible.
