Proficiency in English is a better predictor of educational achievement than English as an Additional Language (EAL)
Full text linkWe compared two tools that have been used to capture the linguistic heterogeneity and achievement of students in England: the exposure-based distinction between English as an additional language (EAL) and monolingual learners, and the 2017–2018 five level teacher rating of proficiency in English (from “New to English” to “Fluent”). Based on a nationally representative sample of 140,000 students aged 5 to 16 years, we assessed the explanatory power of the proficiency in English rating in relation to educational achievement and compared it directly to EAL status. Our results demonstrate that proficiency in English is a significantly better predictor of student achievement than EAL status and that it accounts for up to six times more variance than other student background variables (ethnicity, gender and socio-economic disadvantage) combined. Proficiency in English was particularly (but certainly not solely) predictive for student performance in subjects such as English and reading vis-à-vis mathematics. Our findings are clear in demonstrating the value of a proficiency in English rating for assessing linguistic heterogeneity and student achievement, in contrast to the exposure-based EAL measure. We recommend the (re)introduction of proficiency in English ratings to monitor and support student progress and discuss the value of classroom-based language assessments
English as an Additional Language (EAL) and educational achievement in England: An analysis of the National Pupil Database
No full textThe project was commissioned by three charitable groups – the Education Endowment
Foundation (EEF), Unbound Philanthropy and The Bell Foundation – to analyse the evidence
from national data in England on the achievement of students with English as an Additional
Language (EAL) and to review the literature on effective interventions to raise the attainment
of pupils with EAL. The key questions addressed by the project were:
- Who are the most at-risk groups of EAL learners and what are the predictors of low
attainment for these learners?
- What are the most promising programmes and interventions to address EAL
achievement gaps on the basis of causal evidence?
This report presents an analysis of the most recent England National Pupil Database (NPD)
from 2013 with respect to the first question above. A sister report focuses on the second
question concerning effective interventions and is published in parallel with this report. The
overall purpose of the project is to help schools and policymakers to effectively target policy,
interventions and funding to address achievement gaps.Education Endowment Foundation (EEF), Unbound Philanthropy and The Bell Foundation
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
