irtDemo R Package: Pedagogical Interactive Web Applications for Estimation, Scoring, and Multi Dimensionality in Item Response Theory

Comprehension of foundational but fairly complex statistical theories may require assistive interactive tools to understand underlying equations and theory. We provide a collection web applications demonstrate or explore some the fundamental yet item response theory concepts such as estimation, scoring multidimensionality. Interactive were developed via shiny R package. Users can access these through irtDemo package links provided in this article. hope that give head-start emerging practitioners researchers interested advanced measurement topics.
