Literacy for Life: Evaluating the National Literacy Trust’s bespoke programme for schools

This paper presents an evaluation of ‘Literacy for Life’ (LfL) – a whole-school literacy programme, implemented in five secondary schools in England. The aims of LfL were to improve literacy attainment and to promote positive attitudes to reading and writing. However, when compared to other schools, there is little or no evidence that being in a LfL school, had any differential benefit for pupils’ attainment. In LfL schools, the gap for disadvantaged pupils and those with SEN grew in the early years of the intervention. There is also no evidence from repeated surveys that pupils’ attitudes to and enjoyment of reading showed any improvement. As such, LfL did not achieve its intended objectives. This matters because, despite limited evidence in its favour, schools continue to use it and programmes similar to it. We argue that programmes such as LfL, which are implemented on a whole-school level, need to be based upon evidence-informed approaches

Evaluation of the impact of Maths Counts delivered by teaching assistants on primary school pupils' attainment in maths

This paper presents the findings of a 1-year efficacy trial of Maths Counts (MC), an intensive, individualised programme delivered by trained teaching assistants. The programme was delivered 3 times a week over 10 weeks. The sample included 291 Year 3 to Year 6 pupils (age 7 to 11) from 35 primary schools in England. Pupils were individually randomised within school to receive MC or business as usual. The results suggest that MC is effective for children struggling with basic maths skills (ES = +0.12 for general maths skills and +0.18 for maths attitude), but there is no evidence that it is particularly effective for children eligible for free school meals. Staff and pupil absences, and other social-emotional and behavioural difficulties may have prevented some pupils from getting the most from the programme. In general, the trial shows that trained teaching assistants can be effectively deployed to support children’s maths learning

Incorporating Human Readiness Levels at Sandia National Laboratories

Since 2010, the concept of human readiness levels has been under development as a possible supplement to the existing technology readiness level (TRL) scale. The intent is to provide a mechanism to address safety and performance risks associated with the human component in a system that parallels the TRL structure already familiar to the systems engineering community. Sandia National Laboratories in Albuquerque, New Mexico, initiated a study in 2015 to evaluate options to incorporate human readiness planning for Sandia processes and products. The study team has collected the majority of baseline assessment data and has conducted interviews to understand staff perceptions of four different options for human readiness planning. Preliminary results suggest that all four options may have a vital role, depending on the type of work performed and the phase of product development. Upon completion of data collection, the utility of identified solutions will be assessed in one or more test cases

How to get more people into teaching? Comparing undergraduates’ and teacher trainees’ motivation and perceptions of a teaching career

Understanding people’s perceptions of teaching as an occupation, and their motivation or otherwise to teach, can help identify which initiatives/policies are most promising in improving teacher recruitment. Previous studies have often sought only the views of teachers/teacher trainees to understand why people choose teaching as a career. Recruitment strategies based on evidence from such research are therefore only appealing to those who are already interested in teaching. It is the views of those who might otherwise have gone into teaching that can provide better clues to what we can do to get more people into teaching. This paper compares the views of 4469 undergraduate students and 788 trainee teachers in England. Our analysis goes beyond the usual approach by comparing young people completely uninterested in teaching, those who considered teaching but rejected it, those intending to be teachers, and those already in training. Our study found little or no difference between prospective teachers and others in terms of generic career drivers and the attraction of financial incentives, although prospective teachers tended to have lower levels of qualifications and to come from less prestigious occupational backgrounds. However, those not planning to be teachers are much less concerned about teachers’ workload, suggesting that this is probably not a great deterrent for those considering teaching. Compared to those who intend to be teachers, those who have considered but rejected teaching are less likely to view teaching as intellectually stimulating. They are least likely to see teaching as a high-status profession, offering good promotion prospects and job security. Policies to improve recruitment need to make teaching more attractive to the second group by addressing these issues. Additionally, these policies should be distinct from policies to retain existing teachers

Scale-dependent metric and causal structures in Quantum Einstein Gravity

Within the asymptotic safety scenario for gravity various conceptual issues related to the scale dependence of the metric are analyzed. The running effective field equations implied by the effective average action of Quantum Einstein Gravity (QEG) and the resulting families of resolution dependent metrics are discussed. The status of scale dependent vs. scale independent diffeomorphisms is clarified, and the difference between isometries implemented by scale dependent and independent Killing vectors is explained. A concept of scale dependent causality is proposed and illustrated by various simple examples. The possibility of assigning an "intrinsic length" to objects in a QEG spacetime is also discussed.Comment: 52 page

The Shapes of Dirichlet Defects

If the vacuum manifold of a field theory has the appropriate topological structure, the theory admits topological structures analogous to the D-branes of string theory, in which defects of one dimension terminate on other defects of higher dimension. The shapes of such defects are analyzed numerically, with special attention paid to the intersection regions. Walls (co-dimension 1 branes) terminating on other walls, global strings (co-dimension 2 branes) and local strings (including gauge fields) terminating on walls are all considered. Connections to supersymmetric field theories, string theory and condensed matter systems are pointed out.Comment: 24 pages, RevTeX, 21 eps figure

Fractal Spacetime Structure in Asymptotically Safe Gravity

Four-dimensional Quantum Einstein Gravity (QEG) is likely to be an asymptotically safe theory which is applicable at arbitrarily small distance scales. On sub-Planckian distances it predicts that spacetime is a fractal with an effective dimensionality of 2. The original argument leading to this result was based upon the anomalous dimension of Newton's constant. In the present paper we demonstrate that also the spectral dimension equals 2 microscopically, while it is equal to 4 on macroscopic scales. This result is an exact consequence of asymptotic safety and does not rely on any truncation. Contact is made with recent Monte Carlo simulations.Comment: 20 pages, late

Interventions to promote cost-effectiveness in adult Intensive care units: consensus statement and considerations for best practice from a multidisciplinary and multinational eDelphi study

Background There is limited evidence to guide interventions that promote cost-effectiveness in adult intensive care units (ICU). The aim of this consensus statement is to identify globally applicable interventions for best ICU practice and provide guidance for judicious use of resources. Methods A three-round modified online Delphi process, using a web-based platform, sought consensus from 61 multidisciplinary ICU experts (physicians, nurses, allied health, administrators) from 21 countries. Round 1 was qualitative to ascertain opinions on cost-effectiveness criteria based on four key domains of high-value healthcare (foundational elements; infrastructure fundamentals; care delivery priorities; reliability and feedback). Round 2 was qualitative and quantitative, while round 3 was quantitative to reiterate and establish criteria. Both rounds 2 and 3 utilized a five-point Likert scale for voting. Consensus was considered when > 70% of the experts voted for a proposed intervention. Thereafter, the steering committee endorsed interventions that were identified as ‘critical’ by more than 50% of steering committee members. These interventions and experts’ comments were summarized as final considerations for best practice. Results At the conclusion of round 3, consensus was obtained on 50 best practice considerations for cost-effectiveness in adult ICU. Finally, the steering committee endorsed 9 ‘critical’ best practice considerations. This included adoption of a multidisciplinary ICU model of care, focus on staff training and competency assessment, ongoing quality audits, thus ensuring high quality of critical care services whether within or outside the four walls of ICUs, implementation of a dynamic staff roster, multidisciplinary approach to implementing end-of-life care, early mobilization and promoting international consensus efforts on the Green ICU concept. Conclusions This Delphi study with international experts resulted in 9 consensus statements and best practice considerations promoting cost-effectiveness in adult ICUs. Stakeholders (government bodies, professional societies) must lead the efforts to identify locally applicable specifics while working within these best practice considerations with the available resources
