2/15/2023 0 Comments Nama artis pria pemain ftv sctv![]() I have successfully established a coherent program of research by integrating item response theory (IRT) models, cognitive diagnostic models (CDM), and machine learning methods with multilevel and finite mixture modeling approaches with an aim to exert a positive and lasting effect on measurement practice in large-scale assessments and for cognitive diagnosis purposes. I believe that ultimately this work will promote the use of assessment data for cognitive diagnosis to facilitate learning and instruction. Many of these are due to the use of more complex innovative assessment formats. The overarching goal of my methodological research is to improve the practice in educational and psychological assessment and develop solutions to emerging psychometric challenges. Prior to joining the faculty in Measurement, Statistics, and Evaluation at UMD, I worked as a psychometrician at Harcourt Assessment on different state assessment programs. I received my PH.D from Florida State University in Measurement, Statistics, and Evaluation. I am currently a Professor at the University of Maryland (UMD), College Park specializing in educational measurement and psychometrics in large-scale assessment and also Director of Maryland Assessment Research Center (MARC). ![]()
