Research and Analysis Unit (RandA)

RandA conducts research, training, and analysis activities aimed at improving the methods used for analyzing large-scale assessment data and promoting the use of data from IEA studies. Trainings instruct participants how to soundly analyze data from the studies conducted by the IEA using, for example, multilevel techniques and the IDB Analyzer. They are offered at international education conferences, like AERA and CIES, and on-demand. RandA researchers work in collaboration with a network of educational researchers worldwide. Research findings are presented at international conferences and disseminated through peer-reviewed journals. RandA also liaises with ETS via the IEA/ETS Research Institute.

Research Analysts

Agnes Stancel-Piatak
Agnes has been working for RandA since February 2013. Before joining the IEA DPC, Agnes was a researcher at the University of Hamburg working in the area of evaluation of educational systems. Among others she was involved in the assessment of students' performance in TEDS-LT (Teacher Education and Development Study - Learning to Teach). In her PhD thesis she analyzed the effectiveness of the German school system in mitigating social inequities. Agnes earned a Dipl. Päd. degreee (eq. to MA) in education from the University of Hamburg. Her main research interests are social inequalities, school effectiveness and methods in large-scale assessment. She is specialized on multilevel and latent modeling. Agnes speaks German, English, and Polish.

IEA Data in Research

Papers published in peer-reviewed academic journals

One of IEA's main objectives is to provide high-quality data to increase policymakers' understanding of the key factors that influence teaching and learning and help them identify areas of concern and action within and across systems of education. To realize this aim, the data need to be analyzed and results made available to all stakeholders. IEA and other international agencies produce international and regional reports, and many national agencies do the same at the country level. These reports are normally widely known and distributed, but due to their broad scope, they tend to present results in a general and descriptive fashion. In contrast, academic papers typically have a narrower scope, use more sophisticated analytical techniques, and address very specific research questions. But to what extent are researchers using IEA data for their work? What are the main topics discussed in academic journals?

To answer these questions we compiled a list of abstracts of papers published in academic peer-reviewed journals that interpret and analyze findings from IEA studies. For the community of researchers in educational evaluation, this list provides a broad perspective on the major topics driving the international educational debate. For policy-makers, education managers, teachers, teacher trainers, curriculum developers, and others with a shared aim for educational improvement, the outcomes of secondary analyses help to bridge the gap between research, policy, and practice.

The list of abstracts was retrieved using the EBSCOhost search engine with names of IEA studies as keywords. This is not an exhaustive list, so please help it grow! You can send information about recently published secondary research articles on IEA data to RandA@iea-dpc.de.
