Together with Educational Testing Services (ETS), he established the IEA Research Institute (IERI), where he continues to serve as a Board member.ĭr Wagemaker was a Senior Manager Research and International with the Ministry of Education, New Zealand, and represented New Zealand’s interests in the APEC Education Forum, UNESCO’s commissions, and the OECD, CERI, and the Education Governing Board. He helped develop IEA’s Progress in International Reading Literacy Study (PIRLS) and oversaw the development and expansion of IEA’s training and capacity building activities in low to middle income countries, and IEA’s educational consultancy services. The final chapters address the question of the influence of ILSAs on policy and reform in education, including a case study from Singapore, a country known for its outstanding levels of achievement, but which nevertheless seeks the means of continual improvement, illustrating best practice use of ILSA data.ĭr Hans Wagemaker was the executive director of the International Association for the Evaluation of Educational Achievement for 17 years, responsible for the management of all IEA international research and assessment projects and activities. An often neglected area of investigation, namely the consequential validity of ILSAs, is also explored, examining issues related to reporting, dissemination, and impact, including discussion of the limits of interpretation.
Readers will learn about IEA’s approach to such challenges, and the methods used to ensure that the quality of the data provided to policymakers and researchers can be trusted. The demands of the twin imperatives of validity and reliability must be satisfied in the context of multiple and diverse cultures, languages, orthographies, educational structures, educational histories, and traditions. Research in the complex multinational context in which IEA studies operate imposes significant burdens and challenges in terms of the methodologies and technologies that have been developed to achieve the stated study goals. Throughout the now considerable history of IEA’s international large-scale assessments, establishing the quality of the data has been paramount.
A group of renowned international researchers, directly involved in the design and execution of IEA’s international large-scale assessments (ILSAs), describe the operational and quality control procedures that are employed to address the challenges associated with providing high-quality, comparable data. This open access book describes and reviews the development of the quality control mechanisms and methodologies associated with IEA’s extensive program of educational research.
