On March 11, 2020, the World Health Organization officially declared COVID-19 a global pandemic, causing one of the largest disruptions to schooling in history. The COVID-19 pandemic introduced unprecedented challenges for education research and large-scale assessments of student populations. Both schools and researchers were forced to modify…

English as an additional language (EAL) and language diversity attract much interest amongst policymakers and educationists; yet little is known about the performance in English schools of EAL pupils who are not fluent in English and speak different languages at home. The findings of the aggregated data confirm that EAL pupils achieved less well…

This study examines gender differences in the variability of student performance in reading, mathematics and science. Twelve databases from IEA and PISA were used to analyze gender differences within an international perspective from 1995 to 2015. Effect sizes and variance ratios were computed. The main results are as follows. (1) Gender…

"Methods and Procedures in PIRLS 2016" documents the development of the Progress in International Reading Literacy Study (PIRLS) assessments and questionnaires and describes the methods used in sampling, translation verification, data collection, database construction, and the construction of the achievement and context questionnaire…

Existing tools aim to detect university students with early diagnosis of dyslexia or reading difficulties, but there are not developed tools that let those students better understand some aspects of their difficulties. In this paper, a dashboard for visualizing and inspecting early detected reading difficulties and their characteristics, called…

Over the past few decades, the figure of the market has clearly made its way into the field of education. For some authors, it represents an alternative to regulation by the public authorities, a different form of co-ordination which is better able to meet the objectives of the education systems. Through a secondary analysis of the PISA 2006…

Finland and Shanghai are strong performers in the Program for International Student Assessment (PISA). The current study explored the similarities and differences in educational effectiveness between these 2 strong performers. To this end, 14 predictors representing student background and school process characteristics were selected from the PISA…

This paper investigates empirically whether immigrant students in Switzerland perform poorly compared to their native counterparts and provides some explanations. Using a national sample of the 2000 PISA (Programme for International Student Assessment) database, we first analyze the impact of immigrant status on pupils' achievement. We find a…

The "PISA 2012 Technical Report" describes the methodology underlying the PISA 2012 survey, which tested 15-year-olds' competencies in mathematics, reading and science and, in some countries, problem solving and financial literacy. It examines the design and implementation of the project at a level of detail that allows researchers to…

Social psychologists have suggested that language-based ideologies related to "stereotype threat" (i.e. variations in performance-based on ability perceptions of language groups) may affect students' academic achievement regardless of school language support. However, it is unclear whether efforts to support students' first language…

In this article, the authors develop and test a differential effects model of university entry versus major selection using a set of common predictors, including background factors (gender and socioeconomic status), academic achievement, and academic self-concept. The research used data from 2 large longitudinal databases from Germany (N = 5,048)…

Big-fish-little-pond effect (BFLPE) research has demonstrated that academic self-concept is negatively affected by attending high-ability schools. This article examines data from large, representative samples of 15-year-olds from each Australian state, based on the three Program for International Student Assessment (PISA) databases that focus on…

The technical complexities and sheer size of international large-scale assessment (LSA) databases often cause hesitation on the part of the applied researcher interested in analyzing them. Further, inappropriate choice or application of statistical methods is a common problem in applied research using these databases. This article serves as a…

The Organisation for Economic Cooperation and Development (OECD) underpins its extensive policy work with strong databases of comparable statistics and indicators with which it compares countries. In 2000, it extended its education database with its first collection of data on the performances of 15-year-olds in reading, mathematics and science…

The latent structure of the reading test of the International Association for the Evaluation of Educational Achievement (IEA) Reading Literacy study was investigated. The use of latent class modeling for investigating the measurement properties of a large-scale reading assessment database is demonstrated. The study focused on response data from…
