The authors add to published empirical findings that an appropriate range of validity evidence for achievement tests, including science and mathematics, has either not been gathered, not reported, or is not accessible for independent review. The current study focuses on a sample of published, peer reviewed science intervention studies from a…

Aggregated data meta-analyses indicate a correlation between instructional leadership and student achievement. However, it is unclear to what extent this relationship can be generalized across cultural contexts, as most primary studies stem from Anglophone regions. Drawing on international large-scale assessment data, this 3-level individual…

A considerable body of literature exists pertaining to realistic mathematics education (RME) and its correlation with mathematical literacy, with numerous studies demonstrating incongruent results. The principal objective of this meta-analysis is to systematically investigate the overarching influence of RME on mathematical literacy within the…

GCSE examinations (taken by students aged 16 years in England) are not intended to be speeded (i.e. to be partly a test of how quickly students can answer questions). However, there has been little research exploring this. The aim of this research was to explore the speededness of past GCSE written examinations, using only the data from scored…

Research in international large-scale assessment (ILSA) has become an increasingly popular field of study in education. Consequently, interest and debate in the field by practitioners, researchers, policymakers, and the public has grown over the past decades. This study adopts a descriptive bibliometric approach to map modern research on ILSA in…

In 2018 the OECD published the findings of its PISA for Development (PISA-D) pilot project which was undertaken to make the regular PISA framework more accessible and relevant to low- and middle-income nations. This would encourage such nations to join PISA as part of the OECD's Learning Framework 2030 and provide them with 'contextualised' policy…

Scientific literacy has become the goal of science education throughout the world. To assess scientific literacy, the development of a scientific literacy instrument is imperative. Several scientific literacy instruments have been created, such as those for the Programme for International Student Assessment (PISA) and Project 61 for Science for…

This research is an extensive meta-analysis investigating the link between mathematical literacy and mathematics achievement which are tested mainly in PISA exams. With this aim in mind, first, the studies related to the research objective between the years 2003-2021 were examined. In the second stage, eight studies which met the research criteria…

Higher-order thinking skills (HOT) are expected to be skills needed now and in the future. Many learning strategies are applied to increase HOT. However, how effective is this in improving students' HOT abilities? This study will examine how effective learning is to improve HOT thinking skills. We use meta-analysis research techniques to analyze…

The aim of this research is to explore the research trends of inquiry-based science (IBS) articles in the Web of Science database during 2000-2021. The bibliometric method was used in the research. A total of 662 IBS education articles were included in the study, out of 1389 IBS publications covering all fields published in Web of Science during…

In Comparative Judgement (CJ) exercises, examiners are asked to look at a selection of candidate scripts (with marks removed) and order them in terms of which they believe display the best quality. By including scripts from different examination sessions, the results of these exercises can be used to help with maintaining standards. Results from…

This systematic review analyses the research results of low-achieving grade K-3 children's numeracy competencies by investigating the research approaches used, the definitions of low achievers and the numeracy competencies reported. 18 articles, identified in ERIC, PsycINFO and Web of Science, were selected for further analysis. The results show…

The two main purposes of the current meta-analysis were (1) to determine the relation between socioeconomic status (SES) of students and academic performance (AP) and (2) and evaluate the effect of several potential moderating factors in this relation. Data covered the publications between 2010 and 2019, and the dataset consisted of 48 independent…

The World Bank and other global actors were impressed by the fact that the relatively poor Southeast Asian country Vietnam made significant success in the PISA evaluation in 2012, placing ahead of several Western countries like the US, UK, Australia, and Sweden. In this article, recent research that focuses on educational achievement, specifically…

Optimistic attributional style has been shown to be reliably associated with high well-being and low depression and (Hu et al., "Journal of Social and Clinical Psychology," 34(4): 304-321, 2015). Via both a meta-analysis and two new studies, we examine the relationship between optimistic attributional style for explaining negative and…
