In Kap. 16 wurde das Rasch-Modell als ein Modell der Item-Response-Theorie vorgestellt. Da in Modellen der Item-Response-Theorie die Beziehungen zwischen den Losungswahrscheinlichkeiten einzelner Items und den Auspragungen einer latenten Variablen spezifiziert werden, eignen sich diese Modelle in besonderer Weise zur Selektion von Items fur ein ...

Optimal Designs for the Rasch Model
Psychometrika, 2012In this paper, optimal designs will be derived for estimating the ability parameters of the Rasch model when difficulty parameters are known. It is well established that a design is locally D-optimal if the ability and difficulty coincide. But locally optimal designs require that the ability parameters to be estimated are known.

Residualanalysis in the Polytomous Rasch Model
Psychometrika, 1995Residuals for check of model fit in the polytomous Rasch model are examined. Comparisons are made between using counts for all response pattern and using item totals for score groups for the construction of the residuals. Comparisons are also, for the residuals based on score group totals, made between using as basis the item totals, or using the ...

THE NATURE OF OBJECTIVITY WITH THE RASCH MODEL
Journal of Educational Measurement, 1974Although it has been claimed that the Rasch model leads to a higher degree of objectivity in measurement than has been previously possible, this model has had little impact on test development. Population‐invariant item and ability calibrations, together with the statistical equivalency of any two item subsets, are supposedly possible if the item pool ...

The Rasch Model and Multistage Testing
Journal of Educational Statistics, 1988This paper concerns the problem of estimating the item parameters of latent trait models in a multistage testing design. It is shown that using the Rasch model and conditional maximum likelihood estimates does not lead to solvable estimation equations.

Publisher Summary This chapter begins with the history of the Rasch models (RM) and also discusses some basic concepts and properties of the RM. According to Georg Rasch, the RM should have the following property: a nontrivial likelihood function should exist, which is a function of the item parameters but is independent of the person parameters, and

Wie schon in 1.6 erwahnt verwendet das Rasch-Modell die logistische Funktion als Item-Response-Funktion ϕ (Rasch 1961: 117ff, Andersen 1973: 33, 1973a: 123, 1973b, Birnbaum in Lord, Novick 1968: 402 u.a.) – siehe 2.3.

Polytomous Rasch Models and their Estimation [PDF]
, 1995 In this chapter, the polytomous Rasch model is introduced, based on the original formulation by Georg Rasch in the 1960 Berkeley Symposium on Mathematical Statistics and Probability. The various versions of the basic model, suggested in the literature, are briefly mentioned and compared.

Nachdem in Kap. 16 eine Einfuhrung in das Rasch-Modell gegeben wurde, sollen nun die dort behandelten Inhalte vertieft werden. Zunachst werden wir die Annahme der Rasch-Homogenitat einfuhren, ohne dabei schon auf die latente Personvariable ξ Bezug zu nehmen. Aus der Rasch-Homogenitat folgt ohne weitere Annahmen die Existenz der theoretischen Grosen des

Japanese Language Learning and the Rasch Model
2005This study attempted to evaluate outcome of foreign language teaching by measuring the reading and writing proficiency achieved by students studying Japanese as a second language in six different year levels from year 8 to the first of university in the classroom setting. In order to measure linguistic gains across six years, it was necessary, firstly,
