Short version of the KAT-HS concept published
Prof. Dr. Andreas Frey and Aron Fink, together with Prof. Dr. Christian Spoden and Dr. Sebastian Born have written a short version of the KAT-HS concept, which is now available. Their paper describes four major challenges when it comes to the development of high-quality exams in higher education and specifies how to meet them on the basis of a novel combination of methods, quality standards and approaches stemming from psychometrics and educational and psychological measurement. The concept’s feasibility is classified according to examination law and the general conditions for its implementation in the regular operation of higher education institutions are discussed.

Book chapter on competence-oriented computer-based exams in teacher training released
Prof. Dr. Christian Spoden (DIE Bonn), Prof. Dr. Andreas Frey, Aron Fink and Patrick Naumann have written an article on competence-oriented computer-based university Exams in teacher training, which has now been published in the Waxmann anthology “Bildung, Schule, Digitalisierung” (Eds.: Kaspar, Becker-Mrotzek, Hofhues, König, & Schmeinck).
The chapter presents a concept for adaptive, competence-oriented computer-based exams (KAT-HS; see website) and describes their implementation in university teaching. With the KAT-HS concept, problems of common paper-based exams can be overcome and requirements from the Bologna reform can be implemented.

Paper on the effect of test anxiety and test-taking motivation on person fit published
Prof. Dr. Andreas Frey investigated in cooperation with Prof. Dr. Christian Spoden and Dr. Jens Fleischer the effect of test anxiety and test-taking motivation on person fit by using large-scale data from a german mathematics proficiency test for (self-) evaluation. Person fit statistics make it possible to identify students whose ability estimates might be compromised by estimation bias due to the misfit of their response patterns.
The results showed an effect of the test anxiety on the person fit in specific ability levels (e.g., a negative effect for students with high math ability). Considering this result, the usage of credibility functions as weights for individual response patterns is discussed as a possibility to increase the validity of test scores.

Paper on the benefits of fixed item parameter calibration published
In cooperation with Dr. Lale Khorramdel and Dr. Kentaro Yamamoto of the Educational Testing Service in Princeton, NJ, USA, Dr. Christoph König and Prof. Dr. Andreas Frey investigated the benefits of fixed item parameter calibration (FIPC) for small-sample situations in large-scale assessments. In this study, recently published in Educational Measurement: Issues and Practice, they found that applying FIPC to PISA’s field trial data considerably reduced the sample size requirements for an accurate item calibration. This is beneficial for the flexibility of large-scale assessments, because a greater proportion of the field trial sample can be used to test novel features regarding their feasibility for the PISA main surveys. Consequently, it is easier for large-scale assessments to keep up with current developments in the field of psychometrics and to meet stakeholders’ needs while, at the same time, keeping costs reasonable.

Presentations at the 18th Biennial EARLI Conference
From 12th to 16th August the 18th conference of the European Association for Research on Learning and Instruction (EARLI) took place in Aachen. The conference (“Thinking Tomorrow's Education: Learning from the past, in the present and for the future”) focussed on results and ideas on state-of-the-art research in learning and instruction. Aron Fink held a talk entitled “Testing an explanatory model for the intention to use adaptive and non-adaptive e-exams by the university teaching staff”. This presentation focused on the factors influencing the intention of university lecturers to use (adaptive) e-examinations. Dr. Christoph König “Reducing sample size requirements in large-scale assessments for improving test design flexibility” presented an approach for increasing the flexibility of international large-scale assessments with Fixed Item Parameter Calibration (FIPC). In this approach the parameters of already previously calibrated items (such as the trend items in PISA) are fixed to their known estimates, and only the new item parameters (such as the newly developed items in PISA) are estimated.

Our work unit at the Annual Meeting of the European Mathematical Psychology Group (EMPG)
The 50th Meeting of the European Mathematical Psychology Group (EMPG) took place in Heidelberg from 5th to 7th August 2019. Dr. Christoph König had a talk entitled “Alternatives to the Inverse Wishart distribution in Bayesian hierarchical IRT models”. Based on results of a simulation study, the standard Inverse Wishart distribution (the most popular prior distribution for covariance matrices in Bayesian hierarchical Item Response Theory models) was compared to the performance of three alternative specifications (scaled IW, hierarchical IW, and a separation strategy based on the Cauchy distribution and the Cholesky factor of the correlation matrix) in terms of parameter recovery (Bias and RMSE) in the hierarchical two-parameter logistic (2PL) IRT model. The results show a superior performance of the alternative specifications.

Paper on Equating Setups in the Continuous Itempool Calibration for Computerized Adaptive Testing published in “Frontiers in Psychology”
Dr. Sebastian Born, Aron Fink, Prof. Dr. Christian Spoden and Prof. Dr. Andreas Frey have published an article on equating methods in the continuous calibration strategy in the journal “Frontiers in Psychology”. They investigated different methods for scale transformation using the continuous calibration strategy (Fink et al., 2018) in computerized adaptive tests regarding the estimation accuracy of the item parameters (mean/mean, mean/sigma, Haebara and Stocking-Lord). The characteristic curve methods, in particular Stocking-Lord, turned out to be suitable methods for scale transformation in the continuous itempool calibration for computerized adaptive testing.

Paper on the development of a computerized adaptive test published in the Journal of Computerized Adaptive Testing
A paper on the development of a computerized adaptive test was published recently in the Journal of Computerized Adaptive Testing. Prof. Dr. Christian Spoden, Prof. Dr. Andreas Frey, and Dr. Raphael Bernhard show that the development of such tests, which is widely regarded as time-consuming and resource-intensive, can be accomplished in a relatively short timeframe. They illustrate this with three tests (measuring student competencies in reading, mathematics, and science), which had to be developed and piloted within an 18-month period, and were used directly afterward in a large nationwide research initiative.
