A novel approach to integrating Cluster Analysis (CA) within qualitative inquiry is presented, grounded in a large, unstructured dataset from open and rather unstructured interviews. This dataset was previously subjected to typical (theory sensitive) thematic analyses. Transformed into quantitative binary matrix structures, the CA offers…

This paper compares the use of confidence intervals (CIs) and a sensitivity analysis called the number needed to disturb (NNTD), in the analysis of research findings expressed as 'effect' sizes. Using 1,000 simulations of randomised trials with up to 1,000 cases in each, the paper shows that both approaches are very similar in outcomes, and each…

Two decades of research into early career researchers has highlighted the interaction of a constellation of influences in making sense of their experiences. Such research largely draws on either quantitative or qualitative traditions. While both traditions explore similar phenomena, research questions are often framed differently and use different…

We investigate the impact of external differentiation and vocational orientation of (lower and upper) secondary education on country variation in the mean numeracy skills of, and skills gaps between, adults with low and intermediate formal qualifications. We use data on 30- to 44-year-olds in 18 countries from the 2011-12 round of the Program for…

Increasing numbers of students are applying to university with the International Certificate of Christian Education (ICCE), an alternative to mainstream qualifications based on a biblically-based, individualised curriculum called Accelerated Christian Education (ACE). No formal validity arguments exist for the ICCE, but it claims to prepare…

Despite numerous criticisms of the UK National Student Survey (NSS) institutional managers still strongly support its use in informing student choice, quality and assurance and quality enhancement activities. This article outlines a granular and nuanced benchmarking system for the NSS which provides both a "raw" score (weighted student…

A group of postgraduate accounting and finance students were asked to participate in a three-phase exercise: sit an unseen past examination question; mark a fully anonymised previous student solution (exemplar); and then mark their own work. The marking process was facilitated by explaining and discussing the marking guide, assessment systems and…

This article, updated and expanded from one written for "The Times Educational Supplement", 10 December 2010, asks whether politicians are right to quote the country's performance in international tests in support of such policies as re-introducing O levels. It finds reasons to doubt that the tests give an adequate picture of children's…

Evidence from recent research suggests that in the UK the public perception of errors in national examinations is that they are simply mistakes; events that are preventable. This perception predominates over the more sophisticated technical view that errors arise from many sources and create an inevitable variability in assessment outcomes. The…

The need for education to help every child rather than focus on average attainment has become a more central part of the policy agenda in the US and the UK. Remedial programmes are often difficult to evaluate because participation is usually based on pupil characteristics that are largely unobservable to the analyst. In this paper we evaluate…

When governments and pressure groups attend only to research that suits their political purposes, it makes a mockery of the idea of evidence-informed policy and practice. In this article, the author cites examples of research that picked up weak and misleading evidence for political purposes. The author argues that researchers are tied in to the…

The Centre for the Economics of Education was asked to investigate the factors that influence a range of children's academic and non-academic outcomes, including their enjoyment of school, whether they take unauthorised absence from school and whether they feel they are bullied. The study also investigated whether schools can influence these…

The aim of the National Numeracy Strategy is to raise standards in numeracy. Strong evidence for its success has, however, been lacking: most of the available data come from performance on National Test assessments administered in schools or from Ofsted reports, and is vulnerable to suggestions of bias. An opportunistic analysis of data from a…

The author has been invited to reply to this response to her article of December 2006 in this journal. This response can only be a summary of some of her findings and a reiteration, in very truncated form, of her arguments. She would refer any interested reader back to her original extended review of the PIRLS project as it was there that she lays…

This report presents findings from a review of the best evidence on narrowing the gap in outcomes across the five Every Child Matters (ECM) areas for vulnerable groups in the context of improving outcomes for all. The review was commissioned to prepare the ground for work on "Narrowing the Gap" with participating local authorities (LAs).…
