Item Response Theory

Abstract: Item response theory (IRT) models, in their many forms, are undoubtedly the most widely used models in large-scale operational assessment programs. They have grown from negligible usage prior to the 1980s to almost universal usage in largescale assessment programs, not only in the United States, but in many other countries with active and up-to-date programs of research in the area of psychometrics and educational measurement.Perhaps the most important feature leading to the dominance of IRT in operational pro… Show more

“…The principal goal was to broaden the item pool used to measure each target construct without increasing student response burden. They also advocated the use of item response theory (IRT) for the analysis of the response data (Lord 1980;Carlson and von Davier 2017). IRT has the advantage of enabling the creation of a common proficiency scale across the multiple forms of an instrument that result from a BIB design.…”

“…In our experiments, we use the simplest IRT model often called Rasch model or the one-parameter logistic model (1PL) [16]. According to this model, a learner's response to a question item is determined by her knowledge proficiency level (a.k.a.…”

“…More details about the gathered question set is given in Table 2. Even though we use two methods for assigning difficulty-levels, Method-1 is proven to be the more accurate approach than Method-2 [10,16]. However, finding the actual difficulty-level of the questions using Method-1 requires us to first identify the proficiency level of the test takers.…”

“…Therefore, its main purpose focuses on establishing the individual's position on that continuum. IRT is widely used for large-scale assessments [46], such as PISA (https://www.oecd.org/pisa/) or TOEFL (https://www.ets.org/toefl).…”
