The internal validity of observational study is often subject to debate. In this study, we define the counterfactuals as the unobserved sample and intend to quantify its relationship with the null hypothesis statistical testing (NHST). We propose the probability of a robust inference for internal validity, that is, the PIV, as a robustness index…

There is much discussion about and many policies to address achievement gaps in education among groups of students. The focus here is on a different gap and it is argued that it also should be of concern. Speed gaps are differences in how quickly different groups of students answer the questions on academic assessments. To investigate some speed…

Evolution causes biological and cultural diversity through adaptation to environmental conditions. This idea forms the cornerstone of recent research on the ecological origins of innovation and creativity, advanced prominently by Van de Vliert and Murray (2018) as the "ecotheory of creativity." Van de Vliert and Murray propose that heat…

Measures of socioeconomic status (SES) are widely used in educational research and policy applications in no small part because of a deeply rooted belief of the importance of SES. This paper argues that the usefulness of common SES measures can be undermined by (a) an atheoretical approach to conceptualizing SES and selecting measures, which…

This book explores the influence of high stakes standardised testing within the context of South Korea. South Korea is regarded as a shining example of success in educational achievement and, as this book reveals, pressurised standardised testing has been a major contributing factor to its success. This unique country provides an excellent setting…

This article compares and contrasts the use of mental testing and the formation of educational streaming in Denmark and Ontario during the interwar years. In this sense, the article adds nuances to the meaning of internationalism as well as contributing to our knowledge about how ideas of testing practices circulated among countries and…

This paper will deal, firstly, with the South African context, that cries out for attention to responsible language assessment. The renewed interest in language testing in South Africa is well illustrated in assessments of language ability for educational purposes generally, and more specifically in the assessment of academic literacy. Secondly,…

Many large-scale, school-based interventions have attempted to improve academic performance through promoting students' growth mindset, defined as the belief that one's intellectual ability can increase with practice and time. However, most have shown weak to no effects. Thus, it is important to examine how growth mindset might affect retention…

Examining the relationship between technology and the success of language acquisition and the integration of technology into language instruction has been around of a long time by now. The development of technology can essentially change how languages are taught. Nevertheless, it is only in the last few years that the road has opened up for new…

This article begins by situating modern-day second language acquisition (SLA) research in a historical context, tracing its evolution from cognitive to social to sociocognitive accounts. Next, the influence of the zeitgeist is considered. In this era of rapid change and turmoil, there are both perils and opportunities afforded by globalization. In…

Although the literature on institutional diversity suggests that quality assurance practices could affect institutional diversity, there has been little empirical research on this relationship. This article seeks to shed some light on the possible connection between quality assurance practices and institutional diversity by examining the…

Computer-assisted assessment (CAA) is widely used in modern university courses in many different fields. It can be used both in formative and summative assessments and with different emphasis on (self-)training, grading, and feedback generation. This article reports on experiences from using the CAA tool "JACK" to support a university…

When a constructed-response test form is reused, raw scores from the two administrations of the form may not be comparable. The solution to this problem requires a rescoring, at the current administration, of examinee responses from the previous administration. The scores from this "rescoring" can be used as an anchor for equating. In…

Research investigating corpora of English learners' language raises new questions about how syntactic complexity is defined theoretically and operationally for second language (L2) writing assessment. I show that syntactic complexity is important in construct definitions and L2 writing rating scales as well as in L2 writing research. I describe…

The aim of this research is to study the accurate prediction of comparing test information and evaluation result by multidimensional computerized adaptive scholastic aptitude test program used for grade 9 students under different reviewing test conditions. Grade 9 students of the Secondary Educational Service Area Office in the North-east of…
