LIVE STREAM – 4-day Statistics Short Course
Seminar Overview: Item Response Theory Course
This interactive training course will introduce the concepts of unidimensional and multidimensional IRT models and provide instruction, demonstration, and hands-on opportunities of using the free R software to estimate commonly used IRT models.
- The Rasch, 1PL, 2PL, and 3PL IRT models will be discussed for unidimensional dichotomous data.
- The GR and GPC models will be presented for polytomous data.
- The 2PL model will be explained for multidimensional dichotomous data.
- The analysis of these models and types of data will be implemented using the eRm, ltm, and mirt packages in R.
This item response theory course is perfect for anyone seeking to enhance their researcher skills of using R to do IRT analysis and advance their knowledge of IRT. These may be students, faculty, and researchers from a variety of fields that utilize IRT (e.g., education, psychometrics, psychology, and testing). The audience is expected to have a basic to intermediate knowledge level of general statistics. No prior knowledge of experience of using R to do IRT is necessary. The instructions and training on IRT and the use of R will be taught at an introductory to intermediate level.
