Our research deals with various aspects of empirical educational research. We focus on the following questions: (a) how can innovative, technology-based test methods best be used for educational research, (b) how to statistically model empirical data gathered in educational research best, and (c) which insights about education systems can be obtained from large-scale assessments of student achievement such as PISA, IGLU or TIMSS. Current projects include educational disadvantage due to the coronavirus (CoBi project), the improvement of online teaching using artificial intelligence (HIKOF-DL project), the development of a test on sustainability (OIT-BNE project) and reading comprehension of fourth-graders (PIRLS project).
In teaching, we are active in the educational research parts of the teacher training programs as well as in B.Sc. and M.Sc. Psychology.

New Publication in Education and Information Technologies
Aron Fink and Prof. Dr. Andreas Frey, together with Prof. Dr. Christian Spoden, have published a new paper on Determinants of higher education teachers’ intention to use technology-based exams. This paper proposes the novel technology-based exams acceptance model (TEAM) and empirically evaluates its model structure and usefulness from the perspective of higher education teachers. With TEAM, a highly predictive model for explaining the behavioral intention to use e-exams is now available. It offers a theoretical basis that can be used for the successful implementation of e-exams in higher education.
The paper is published in Education and Information Technologies erschienen as open access:

New Publication in Behavior Research Methods
Dr. Christoph König and Prof. Dr. Andreas Frey, together with Prof. Dr. Christian Spoden, have published a new paper on Bayesian hierarchical modeling of Item Response Theory (IRT) models. In an extensive simulation study, the robustness of the performance of a previously optimized Bayesian hierarchical 2PL IRT model was investigated and compared to a number of alternative estimation methods and approaches. We could show that the optimized model exhibits a relatively robust performance, especially in small samples, and outperforms alternative approaches in a wide range of conditions. Thus, this simulation study contributes to the extension of applicability of IRT models to, for instance, university contexts, where small samples and suboptimal test conditions are prevalent, and IRT models are seldom used.
The paper is published as an open access publication in Behavior Research Methods, and is available here:

The CoBi project family grows
The Beisheim-Stiftung is funding the project " Coronabedingte Bildungsbenachteiligungen erkennen und verringern – Online” (CoBi-Online) for two years (2022-2024). CoBi-Online is the third project of the CoBi project family (besides CoBi and CoBi-Transfer). CoBi-Online aims at transferring the learning support system developed in the CoBi project to a video-based online context and at offering it beyond Hesse. Thus, CoBi-Online will be making another important contribution to mitigating the educational disadvantages created by the Corona pandemic and to supporting students in Germany to optimize their learning.

Project CoBi-Transfer started
The project „Coronabedingte Bildungsbenachteiligungen erkennen und verringern - Transfer“ (CoBi-Transfer) conducted by the Goethe University Frankfurt (Prof. Dr. Andreas Frey) is funded by the Hessian Ministry of Education as part of the Loewenstark-Program in the school year 2022/2023. CoBi-Transfer allows the CoBi Learning Support System (developed in the CoBi project funded by the Beisheim Stiftung and the Goethe Corona Fonds) to be offered to students in K-12 education in the Frankfurt area and beyond. Thus, CoBi-Transfer further contributes to mitigating the educational disadvantages caused by the Corona pandemic by supporting students in optimizing their learning.

Summer semester end in Goethe's footsteps
The end of the semester was hot, 35 degrees. This time fearlessly on the move again, but without an overweight dog: Team Frey. Start at the Goethe House, then along the banks of the Main, into the cool city forest, have a cold drink at the Goethe Tower, preferably Hessian, and then hike through Sachsenhausen to the Ristorante with courtyard garden in the evening. There relaxation, benevolent review of research, projects and teaching in the summer semester and strengthening with fine delicacies. Satisfied, slowly evaporating, we indulged in relaxation and fooling around. Energy and confidence for new tasks!

New publication on learning to read during the Corona pandemic
Dr. Ulrich Ludewig, Ruben Kleinkorres, Dr. Rahim Schaufelberger, Theresa Schlitter, Dr. Ramona Lorenz, Dr. Christoph König, Prof. Dr. Andreas Frey and Prof. Dr. Nele McElvany have published a research paper on the state of reading literacy after corona-related limitations in schooling. They examined the data from 4,290 fourth graders* from 111 schools in Germany. The observed significant decline in reading literacy from 2016 to 2021 can only be partially explained by changes in the student composition. The observed decline is way beyond typical changes during five years in average reading achievement as found in large-scale assessment. Thus, it is likely that this decline in average reading achievement is at least partly associated with COVID-19-related measures.
The paper was published with open access in Frontiers in Psychology: Ludewig, U., Kleinkorres, R., Schaufelberger, R., Schlitter, T., Lorenz, R., Koenig, C., Frey, A., & McElvany, N. (2022).

Report on the PIRLS reading literacy test on the reading literacy of fourth graders in Germany before and during the COVID-19 pandemic
Prof. Dr. Andreas Frey, together with Dr. Ulrich Ludewig, Theresa Schlitter, Dr. Ramona Lorenz, Ruben Kleinkorres, Dr. Rahim Schaufelberger, and Prof. Dr. Nele McElvany, published a report on the reading literacy of fourth graders in Germany before and during the COVID-19 pandemic.
For the report, data from 4,290 fourth graders from 111 schools in Germany who took the comprehensive PIRLS reading literacy test in 2016 and 2021 were analyzed. Compared to 2016, fourth graders in 2021 who had been affected by COVID-19-related schooling restrictions for more than one year had, on average, statistically significant and substantially lower reading literacy.

What I haven't learned, I have traveled [J. W. Goethe]
We ended our all around successful year 2021 with a hike around the Saalburg in the most beautiful atmospheric flurry of snow. Armed with a dog, cookies, sandwiches, hot cider and tea, we tackled the sometimes challenging, yet delightful hiking route. One and a half kilometers from the designation, a delegation had to stay behind with the limping dog. Amid the growing darkness, the boss initiated the rescue and recovery of the animal and brought everyone back safely to the designation, where we ended up rewarding ourselves with the remaining treats and the work report of the previous year. It was very amusing and we laughed a lot at ourselves.
The entire department hopes that this positive end will herald a good year for all of us and wishes our visitors of this site a Merry Christmas and a happy and prosperous New Year!

Book on psychometrically sound e-exams in higher education published
Prof. Dr. Andreas Frey and Prof. Dr. Christian Spoden have published a book that presents a concept for psychometrically sound e-exams based on the current state of scientific knowledge. The concept can be applied in all disciplines at all higher education institutions. The concept relies on the use of digital technologies to make exams more individualized, more precise, and fairer. Exams are thereby designed as criterion-referenced, computerized adaptive testing procedures. In this book, the necessary steps for the psychometrically sound e-exam-based measurement of competence are explained in detail.
The book also contains chapters by Aron Fink and Patrick Naumann, who are members of the working unit. With the publication at Pabst Science Publishers, a milestone of the KAT-HS project (Criterion-Referenced Adaptive Testing in Higher Education) is reached.
