Background: Over the last 20 years, educational large-scale assessments have undergone dramatic changes moving away from simple paper-pencil assessments to innovative, technology-based assessments. This comprehensive switch has led to some rather technical improvements such as identifying early guessing or improving standardization. Objectives: At…

This article explores the history of digital testing technology. Using an organisation that pioneered the use of international large-scale assessments -- the International Association for the Evaluation of Educational Achievement (IEA) -- I discuss the role of computers, punched cards, answer cards and scanning machines as an example of…

Digital technologies have the potential to revolutionize education by enhancing quality, fairness, and efficiency. However, equitable access to these technologies remains a challenge. ILSAs (international large-scale assessments) have shown that the relationship between digital use and performance varies across countries and over time. To fully…

Existing data sets can be an efficient, powerful, and readily available resource for addressing questions about developmental science. Many of the available databases contain hundreds of variables of interest to developmental psychologists, track participants longitudinally, and have representative samples. In this article, the authors discuss the…

The success of data mining relies on the availability of high quality data. To ensure quality data mining, effective information sharing between organizations becomes a vital requirement in today's society. Since data mining often involves sensitive information of individuals, the public has expressed a deep concern about their privacy.…

Purpose: The purpose of this paper is to develop a test for data centres, repositories and archives to determine OAIS functional model conformance. The test developed was carried out among the World Data Centre (WDC) member data centres. The method used to develop the OAIS functional model conformance test is discussed, along with the test…

In this paper we describe the development and refinement of "evidence rules" and "measurement models" within the "evidence model" of the "evidence-centered design" (ECD) framework in the context of the "Packet Tracer" digital learning environment of the "Cisco Networking Academy." Using…

Innovations in data processing permit more intensive analysis of major collective bargaining settlements. (Author)

The proposed taxonomy of tasks to be performed in an educational evaluation system encompasses tasks appropriate for evaluators, members of an evaluation unit, and members of facilitation and coordination units. The taxonomy classifies and specifies tasks for (1) developing a climate for evaluation; (2) selecting decision situations, selecting…

New ways of obtaining environmental data are being developed to meet the demand for comprehensive, accurate, and timely information on the environment. This article examines four developments that are transforming the entire field of environmental measurement: spectroscopy; satellite transmission of environmental data; remote sensing; and…

The report summarizes work done in the study of measures for the effectiveness of the performance of large file systems. It consists of six sections: An "Introduction and Summary" which describes the background for the study, the approach taken in it, and summarizes the results; A discussion of the "Forms of Input", which characterizes the basic…

SUCH QUESTIONS AS WHY AND HOW OPERATIONS RESEARCH (OR) AND SYSTEMS ANALYSIS ORIGINATED, WHAT THEY ARE, AND WHAT CONTRIBUTIONS THEY MIGHT MAKE TO INSTRUCTIONAL MEDIA PROGRAMS ARE ANSWERED. "OR" ORIGINATED AT THE OUTBREAK OF WORLD WAR II WHEN MILITARY ORGANIZATIONS, WHICH HAD BEEN DEVELOPING THEIR TECHNOLOGY FASTER THAN IT COULD BE…

EQUALS is a teacher education program that helps elementary and secondary educators acquire methods and materials to attract minority and female students to mathematics. It supports a problem-solving approach to mathematics which has students working in groups, uses active assessment methods, and incorporates a broad mathematics curriculum…

Measures, tools, and techniques applicable to the performance measurement of computer communication networks are described for technicians who procure computer services from a remote access network. Cost considerations are discussed as a major component of evaluation, and measurement and evaluation methodologies are surveyed. External measurement…
