Testing Assumptions in Longitudinal Cognitive Diagnostic Models - Psychology Lecture Series

Psychology Lecture Series - Virtual Talk

Title - Testing Assumptions in Longitudinal Cognitive Diagnostic Models

Speaker - Athul Sudheesh
PhD Student - UT Dallas

On MS Teams. Fill out our MS Form to register for this or any of our talks.

In classroom settings, we infer changes in a student's ability through traditional assessments like formative assessments and summative assessments. A recent approach that combines the diagnostic nature of formative assessment with test properties of the high-stakes summative assessments is the Cognitive Diagnostic Assessments (CDAs). CDAs use latent class models like Cognitive Diagnostic Model to estimate the question characteristics and skill profile of students. In this talk we discuss the assumptions modelers make while using CDMs for semester-long courses and what we found testing those assumptions with the ASSISTment MATH 2004-2005 dataset. ASSISTment is an online tutoring system and ASSISTment MATH is the data collected from 8th-grade students who took tests in that system, once every two weeks during 2004-2005.
