Descriptive analyses of socially important or theoretically interesting phenomena and trends are a vital component of research in the behavioral, social, economic, and health sciences. Such analyses yield reliable results when using representative individual participant data (IPD) from studies with complex survey designs, including educational…

IEA's International Computer and Information Literacy Study (ICILS) 2018 investigated how well students are prepared for study, work, and life in a digital world. ICILS 2018 measured international differences in students' computer and information literacy (CIL): their ability to use computers to investigate, create, participate, and communicate at…

The International Computer and Information Literacy Study (ICILS) studied the extent to which young people have developed computer and information literacy (CIL) to support their capacity to participate in the digital age. Many countries recognize the importance that education in information and communication technologies (ICT) has for enabling…

We show that the neurological condition of synaesthesia--which causes fundamental differences in perception and cognition throughout a lifetime--is significantly represented within the childhood population, and that it manifests behavioural markers as young as age 6 years. Synaesthesia gives rise to a merging of cognitive and/or sensory functions…

The Programme for International Assessment of Adult Competencies (PIAAC) will establish technical standards and guidelines to ensure that the survey design and implementation processes of PIAAC yield high-quality and internationally comparable data. This document provides a revised version of the technical standards and guidelines originally…

Over the past two decades, several two-tier multiple-choice diagnostic tests in science at a variety grade levels have been reported in the extant literature from several countries. This review summarises these studies, provides an overview of the methodology for their construction, presents two examples of typical items, and lists studies…

To support and promote secondary analyses, the International Association for the Evaluation of Educational Achievement (IEA) is making the SITES 2006 international database and accompanying User Guide available to researchers, analysts, and public users. The database comprises national contexts and school- and teacher-level data from 23 education…

This technical report and user's guide is designed to provide researchers with an overview of the design and implementation of the 2009 Program for International Student Assessment (PISA), as well as with information on how to access the PISA 2009 data. This information is meant to supplement that presented in Organization for Economic Cooperation…

Reports the methodology and results of a study which explored the potential of three approaches to sampling the Australian Bibliographic Network (ABN) database files for determining collection overlap among Australian libraries. (Author/CLB)

A survey was conducted of expert instructional design practitioners about their use of developmental testing and revision procedures. The degree of correspondence was examined between published recommended practice and actual practice, as reported by 90 respondents to a questionnaire. The surveyed sample were members of the National Society for…

The operational preparations for the Dutch national assessment program in education started in 1986. The program's aim is to periodically describe the contents of the curriculum in use and the attainment of 8-year-old and 11-year-old students on a national basis by means of surveys. In this paper some of the guiding principles in instrument…

The stability of Rasch test item difficulty parameters was investigated under varying conditions. Data were taken from a mathematics achievement test administered to over 2,000 Australian students. The experiments included: (1) relative stability of the Rasch, traditional, and z-item difficulty parameters using different sample sizes and designs;…
