Language Testing, 1985
A perennial problem for language testers is the need to construct and select test items with 'good' properties. The difficulty lies in the need to assess the properties of items by trying them out on a sample of subjects whose abilities, in turn, it ought to be possible to measure by observing their response to the items. This paper discusses the more

The Counseling Psychologist, 1999
Item response theory (IRT) seeks to model the way in which latent psychological constructs manifest themselves in terms of observable item responses; this information is useful when developing, evaluating, and scoring tests. After providing an overview of the most popular IRT models (i.e., those applicable to dichotomously keyed items) and contrasting

Item response theory (IRT) is a psychometric modeling framework for analyzing categorical data from questionnaires, tests, and other instruments that aim to measure underlying latent traits. Simply speaking, these models estimate a parameter for each item, as well as a parameter for each person.

Item Response Theory Methods [PDF]
, 1995 In this chapter, we describe item response theory (IRT) equating methods under various designs. This chapter covers issues that include scaling person and item parameters, IRT true and observed score equating methods, equating using item pools, and equating using polytomous IRT models.

During the past 30 years or so, a new theoretical basis for educational and psychological testing and measurement has emerged. It has been variously referred to as latent trait theory, item characteristic curve theory, and, more recently, item response theory (IRT).

Dieses Kapitel gibt einen Uberblick uber die wichtigsten Modelle und Methoden der Item-Response-Theorie (IRT). Die IRT stellt Modelle zur psychometrischen Analyse und Skalierung von Test- und Fragebogenitems insbesondere mit nominalem und ordinalem Skalenniveau zur Verfugung. Als eines der einfachsten und bekanntesten IRTModelle wird zunachst das Rasch-

Abstract Classical test theory (CTT) has been the underpinning for most test construction and theory for nearly a century. One reason for its popularity is that the assumptions that CTT makes about the items and the test are relatively ‘weak’ ones (e.g.

Die besondere Leistung der Item-Response-Theorie beruht auf einer spezifischen Bearbeitung der Relation von Person und Test. Wahrend die klassische Testtheorie darauf abzielt, den Test an einer Eichpopulation zu einem neutralen Messinstrument der gegebenen Antworten zu machen, verlagert die Item-Response-Theorie die Funktion der Neutralitat auf die ...

Item bias and item response theory
International Journal of Educational Research, 1989Abstract In this chapter the definition, detection, and explanation of item bias is discussed. Item bias is generally defined as conditional dependence; within the framework of item response theory the general definition implies that the item characteristic curves of two groups do not coincide.

On the Complexity of Item Response Theory Models
Multivariate Behavioral Research, 2017Complexity in item response theory (IRT) has traditionally been quantified by simply counting the number of freely estimated parameters in the model. However, complexity is also contingent upon the functional form of the model. We examined four popular IRT models-exploratory factor analytic, bifactor, DINA, and DINO-with different functional forms but ...
