Brokering knowledge from laboratory experiments in evidence‐based education
The turn to ‘evidence‐based education’ in the past three decades favours one type of evidence: experiment. Knowledge brokers ground recommendations for classroom practice on reports of experimental research. This paper distinguishes field and laboratory experiments, on the basis of control and precision of causal ascription. Briefly noting problems with knowledge brokers’ extrapolating from field experiments, the paper's main focus is on extrapol…
Benchmarking a Misnomer
A recent article calculates new benchmarks from the distribution of effect sizes in a dataset, without accounting for signed values or sampling appropriately. In addition, the focus-narrowing approach it takes does little to address the issues highlighted about the value of effect size for policy
The production of ejectives in German and Georgian
This paper aims to shed light on the textbook description of ejective production through an analysis of the articulatory measures intraoral pressure and larynx height in a data set of phonological Georgian ejectives and epiphenomenal German ejectives. By comparing articulatory mechanisms for ejective production in these two languages, we aim to learn about how ejectives gain phonological status in a language. 14 female German speakers and 13 fema…
Gender (Conformity) Matters
Although sexual orientation (SO) is perceptually ambiguous, people are able to detect it with above-chance accuracy from faces and, sometimes, from voices. Despite a multitude of "gaydar" studies, it is unclear (1) whether vocal or facial signals carry more SO information, (2) whether raters refer to target's SO instead of gender-role conformity when forming SO impressions, and (3) whether there are any differences for female and male targets. We…
Whose Prior Is It Anyway? A Note on “Rigorous Large-Scale Educational RCTs Are Often Uninformative”
A recent paper uses Bayes factors to argue a large minority of rigorous, large-scale education RCTs are “uninformative.” The definition of uninformative depends on the authors’ hypothesis choices for calculating Bayes factors. These arguably overadjust for effect size inflation and involve a fixed prior distribution, disregarding the trials’ varied intentions
The structure of surveys and the peril of panels
University league tables give the image that there is a single dimension along which institutions can be placed. Most derive rankings from an aggregate score of multiple items, which often include opinion responses which has the potential to introduce sampling bias. This paper explores what happens when the two issues of dimensionality and sampling bias interact in league tables. It uses the Times Higher Education Student Experience Survey – whic…
Princesses are bigger than elephants
Much of the evidential basis for recent policy decisions is grounded in effect size: the standardised mean difference in outcome scores between a study's intervention and comparison groups. This is interpreted as measuring educational influence, importance or effectiveness of the intervention. This article shows this is a category error at two levels. At the individual study level, the intervention plays only a partial role in effect size, so tre…
Individual differences in acoustic and articulatory undershoot in a German diphthong – Variation between male and female speakers
The misdirection of public policy
Increased attention on ‘what works’ in education has led to an emphasis on developing policy from evidence based on comparing and combining a particular statistical summary of intervention studies: the standardised effect size. It is assumed that this statistical summary provides an estimate of the educational impact of interventions and combining these through meta-analyses and meta-meta-analyses results in more precise estimates of this impact …
The surprising persistence of Biglan's classification scheme
Within higher education systems, different institutions deliver different patterns of disciplines. A simple analysis of the structure of that pattern of disciplines across institutions in one higher education system uncovers a surprising relationship. That is, the key dimensions which describe that structure align nearly perfectly with dimensions discovered in a very different context: the Biglan classification scheme. This paper explains corresp…
Assessment and its outcomes
Existing research provides evidence at the module level of systematic differences in patterns of assessment, marks achieved and distributions of marks between different disciplines. This paper examines those issues at the degree course level, and suggests reasons for the presence or absence of those module-level relationships at this higher level. The analysis finds that both discipline and institution have large and roughly equal impact on the b…
Students’ views of oral performance assessment in mathematics
This paper explores the views of a group of students who took an oral performance assessment in a first-year mathematics module. Such assessments are unusual for most subjects in the UK, but particularly within the generally homogenous assessment diet of undergraduate mathematics. The evidence presented here resonates with some, but not all, of the existing literature on oral assessment and suggests that, despite concerns about anxiety and fairne…
Students' preferences in undergraduate mathematics assessment
Existing research into students' preferences for assessment methods has been developed from a restricted sample: in particular, the voice of students in the ‘hard-pure sciences’ has rarely been heard. We conducted a mixed method study to explore mathematics students' preferences of assessment methods. In contrast to the message from the general assessment literature, we found that mathematics students differentially prefer traditional assessment …
Differences in acoustic vowel space and the perception of speech tempo
Non-pulmonic sounds in European languages

The first and second harmonics should not be used to measure breathiness in male and female voices
Classification and Concept Consistency
Phonetic differences between male and female speech
The main phonetic differences between the speech of male and female speakers are described and explanations that have been offered to account for these differences are critically discussed
Acoustic and auditory correlates of non-pulmonic sound production in German
Different types of non-pulmonic sound production found in read and spontaneous German are described and exemplified. Stop releases driven by a glottalic airstream are found in sequences of final plosive plus glottalized vowel onset. Both ingressive and egressive velaric stop releases are considered to arise from double occlusions involving partial articulatory overlap in sequences of dorsal stop followed by an apical or bilabial stop. Certain asp…
Gender-specific articulatory-acoustic relations in vowel sequences
Does articulatory reduction miss more patterns than it accounts for
Articulatory explanations are often proposed to account for many of the phonetic patterns found in speech beyond the citation form. Unscripted material from Suffolk English and North German is used to argue that articulatory explanation can too tightly constrain our expectations of the types of phonetic patterns which spontaneous speech contains. It is also shown how articulatory explanation can offer an adequate account of a dataset, stopping sh…
