Racism, masculine peer-group relations and the schooling of African/Caribbean infant boys

The past decade has witnessed the publication of a growing number of important ethnographic studies investigating the schooling experiences of Black students. Their focus has largely been upon student-teacher relations during the students' last few years of compulsory schooling. What they have highlighted is the complexity of racism and the varied nature of Black students' experiences of schooling. Drawing upon data from a year-long ethnographic study of an inner-city, multi-ethnic primary school, this paper aims to compliment these studies in two ways. Firstly the paper will broaden the focus to examine how student peer-group relations play an integral role, within the context of student-teacher relations, in shaping many Black students' schooling experiences. By focussing on African/Caribbean infant boys, it will be shown how student-teacher relations on the one hand, and peer-group relations on the other, form a continuous feed-back loop; the products of each tending to exacerbate and inflate the other. Secondly, by concentrating on infant children, the paper will assess the extent to which these resultant processes and practices are also evident for Black pupils at the beginning of their school careers - at the ages of five and six.

Estimates of peer effects in adolescent smoking across twenty six European countries

Although it is widely believed that one of the key factors influencing whether an adolescent smokes or not is the smoking behaviour of his or her peers, empirical evidence on the magnitude of such peer effects, and even on their existence, is mixed. This existing evidence comes from a range of studies using a variety of country-specific data sources and a variety of identification strategies. This paper exploits a rich source of individual level, school-based, survey data on adolescent substance use across countries - the 2007 European Schools Survey Project on Alcohol and Other Drugs - to provide estimates of peer effects between classmates in adolescent smoking for 75,000 individuals across 26 European countries, using the same methods in each case. The results suggest statistically significant peer effects in almost all cases. These peer effects estimates are large: on average across countries, the probability that a 'typical' adolescent smokes increases by between.31 and.38 percentage points for a one percentage point increase in the proportion of classmates that smoke. Further, estimated peer effects in adolescent smoking are stronger intra-gender than inter-gender. They also vary across countries: in Belgium, for example, a one percentage point increase in reference group smoking is associated with a.16 to.27 percentage point increase in own smoking probability; in the Netherlands the corresponding increase is between.42 and.59 percentage points. © 2011 Elsevier Ltd.

A multiagent network for peer norm enforcement

In a multiagent system where norms are used to regulate the actions agents ought to execute, some agents may decide not to abide by the norms if this can benefit them. Norm enforcement mechanisms are designed to counteract these benefits and thus the motives for not abiding by the norms. In this work we propose a distributed mechanism through which agents in the multiagent system that do not abide by the norms can be ostracised by their peers. An ostracised agent cannot interact anymore and looses all benefits from future interactions. We describe a model for multiagent systems structured as networks of agents, and a behavioural model for the agents in such systems. Furthermore, we provide analytical results which show that there exists an upper bound to the number of potential norm violations when all the agents exhibit certain behaviours. We also provide experimental results showing that both stricter enforcement behaviours and larger percentage of agents exhibiting these behaviours reduce the number of norm violations, and that the network topology influences the number of norm violations. These experiments have been executed under varying scenarios with different values for the number of agents, percentage of enforcers, percentage of violators, network topology, and agent behaviours. Finally, we give examples of applications where the enforcement techniques we provide could be used.

Critical Dialogue in Architecture Studio: Peer Interaction and Feedback

Most tutors in architecture education regard studio-based learning to be rich in feedback due to is dialogic nature. Yet, student perceptions communicated via audits such as the UK National Student Survey appear to contradict this assumption and challenge the efficacy of design studio as a truly discursive learning setting. This paper presents findings from a collaborative study that was undertaken by the Robert Gordon University, Aberdeen, and Queen’s University Belfast that develop a deeper understanding of the role that peer interaction and dialogue plays within feedback processes, and the value that students attribute to these within the overall learning experience.

The paper adopts a broad definition of feedback, with emphasis on formative processes, and including the various kinds of dialogue that typify studio-based learning, and which constitute forms of guidance, direction, and reflection. The study adopted an ethnographic approach, gathering data on student and staff perceptions over the course of an academic year, and utilising methods embracing both quantitative and qualitative data.

The study found that the informal, socially-based peer interaction that characterises the studio is complementary to, and quite distinct from, the learning derived through tutor interaction. The findings also articulate the respective properties of informal and formally derived feedback and the contribution each makes to the quality of studio-based learning. It also identifies limitations in the use or value of peer learning, understanding of which is valuable to enhancing studio learning in architecture.

Improving attainment across a whole district: school reform through peer tutoring in a randomized controlled trial

Districts are an important unit for administrative purposes, but they vary little in their impact on students’ attainment, at least in the UK. Further, government attempts to raise attainment are often disappointing. The project described in this article aimed to engage schools in reform to change students’ attainment and attitudes in schools across a whole district. The intervention, peer tutoring, has a good research pedigree in small-scale studies, but scaling it up to district-level implementation has not been rigorously evaluated. Over 2 years, 129 elementary schools in 1 Scottish district were randomly assigned to different interventions. The implementation was not perfect, but the results were positive with respect to cross-age tutoring, which had effect sizes of about 0.2. Despite limitations, the study demonstrates that it is possible to carry out a clustered randomized controlled trial (RCT) on a large scale working with districts and suggests that peer tutoring has promise when scaled up.

Peer tutoring in reading: The effects of role and organization on two dimensions of self-esteem

Background. Paired reading (PR) is an application of peer tutoring. It has been extensively researched, and its efficacy across a range of outcomes has been established. Benefits include improvements in key reading skills, and also in affective aspects of learning. Several studies have shown gains in self-esteem, although measurement methods have varied, and the model of self-esteem has rarely been clearly articulated.
Aims. To investigate the changes in self-esteem of children participating in a randomized trial of PR over a 15-week treatment period. To investigate the relative contribution of self-worth and self-competence to any gains in self-esteem. To investigate whether the pattern of change differs in children who take on different roles in the PR process.
Participants. The participants comprised a subset of a large-scale randomized trial of peer learning (The Fife Peer Learning Project). Four schools were randomly selected from schools allocated to the same-age PR condition, and four schools from those allocated to the cross-age PR condition. The same-age group consisted of 87 primary 6 children (10–11 years old). The cross-age group consisted of 81 primary 6 children. The controls, from schools randomly selected from a neighbouring authority, consisted of 92 primary 6 children.
Method. A pre–post design employing self-report measures of self-esteem. Rosenberg’s Self-Esteem Scale was used, with scores analysed for worth and competence. The treatment period was 15 weeks, with the participants following a prescribed PR process.
Results. Significant pre–post gains were noted in self-esteem, driven predominantly by improved beliefs about competence, in both same-age and cross-age conditions, but not for controls. Gains were also seen in self-worth in the cross-age condition. Further analyses of the influence of organizational condition (same-age or cross-age) and role played (tutor vs. tutee) showed significant differences between same-age tutors and cross-age tutors in relation to self-worth. Effect sizes were generally small or moderate.
Conclusions. The findings provide further support for the belief that PR can enhance self-esteem. Importantly, the use of a two-dimensional model provides extra information about self-perceptions in PR contexts: first, the central role of self- competence; and second, the gains in self-worth which are associated with tutoring younger children (but not same-age peers). This new information has educational significance for schools considering the potential of peer tutoring and the benefits of different organizational conditions.

Peer injecting: implications for injecting order and blood-borne viruses among men and women who inject heroin

A large body of research has highlighted practices and rituals that characterise injecting drug use and behavioural and environmental risks that can contribute to the transmission of blood-borne viruses. Compared with other injecting practices, considerably less is known about peer injecting, i.e. receiving or giving injections, particularly the social context in which it occurs. In this article, we explore peer injecting and injecting order at initiation into injecting drug user (IDU) and during subsequent injection episodes. Using data from semi-structured interviews, we highlight the experiences of 41 males and females who had received injections from other IDUs. Respondents were recruited through various strategies, largely chain referral. The results suggest gendered similarities as well as differences in terms of peer injecting, the order of injection and micro-risk contexts for blood-borne viruses. © 2013 Informa UK Ltd.

Peer tutoring in reading in Scotland:Thinking big

A large-scale randomised-controlled trial of reading tutoring in 80 schools in Scotland used the Paired Reading (PR) technique. On long-term evaluation, cross-age PR was significantly better than regular teaching, but same-age was not. On short-term evaluation, PR pupils did significantly better than control pupils in both years, and cross-age and same-age were similarly effective. Low socio-economic pupils, lower reading ability pupils, girls and reading with maths tutoring groups did significantly better. Implementation was good in parts, but some important aspects of technique were rare. Reading gains were significantly greater for those with mistakes about every 2 minutes and those who stopped reading to talk every 5 to 7 minutes. Significant gains in self-esteem were seen in same-age and cross-age groups, and for tutees and tutors, but not for controls. The relationship of achievement gain to quality of technique and socio-emotional gains is discussed, with implications for practice. Copyright © 2011 UKLA.

Peer assisted learning in health education.

There are many forms of Peer Assisted Learning (PAL). There are well-established theoretical models as to why PAL is proven to be effective across educational sectors. To maximise gains from PAL careful consideration needs to be given to the roles of peers. Evidence suggests that PAL projects with clearly defined roles for interaction result in strongest outcomes. Effect Sizes (ES) from meta-analyses of peer assisted learning indicate ES of between 0.25-0.50. Outcomes can be social and emotional as well as academic. PAL generally requires adaptation of existing resources and can be cost-effective to implement compared to other educational developments.

The impact of peer review on the radiotherapy treatment planning process in the treatment of lung cancer

Background:
Advanced radiotherapy techniques permit accurate delivery of radiotherapy to lung tumours. Improved accuracy increases the possibility of radiotherapy field geographic miss of the tumour. One source of error is the accuracy of target volume (TV) delineation by the clinical oncologist. Colleague peer review of all curative intent lung cancer plans has been mandatory in our institution since May 2013. At least 2 clinical oncologists review plans checking treatment paradigm, TV delineated, dose to tumour and dose to critical organs. We report the impact of peer review on the radiotherapy planning process for lung cancer.

Methods:
The radiotherapy treatment plans of all patients receiving radical radiotherapy were presented at weekly peer review meetings after their TVs volumes were provisionally signed off by the treating consultant or post-fellowship registrar. All cases and any resultant change to the treatment plan were recorded in our prospective peer review database. We present the summary of changes agreed following the peer review process for a 6 month period.

Results:
Fifteen peer review sessions, including 46 patients (36 NSCLC, 10 SCLC) were analysed. An average of 3 cases were discussed per meeting (range 1 5). 24% of treatment courses were changed. In 4% there was a complete change in paradigm
of treatment (1 patient proceeded to induction chemotherapy, 1 patient had high dose palliative radiotherapy). In 16% there was a change in TV delineated and in 9% a change in dose (2 dose reductions and 2 alterations to post-operative dose fractionations).

Conclusions:
Consultant led peer review resulted in a change in a component of the treatment plan for 28% of patients that would not otherwise have taken place. Given this impact, consultant led peer review should be considered as an essential component in the radiotherapy planning process for all patients treated with curative radiotherapy.

Meta-analysis of the influence of experimental design on effect size in peer tutoring outcomes in elementary, middle and high school settings.

A meta-analysis was undertaken on a form of cooperative learning, peer tutoring. The effects of experimental design on outcomes were explored, as measured by Effect Size (ES). 185 studies were included in the meta-analysis. Highest ES were reported for quasi-experimental studies. ES reduced as experimental design moved from single pre-test factor matched, to multiple-factor matched randomized controlled trials. ES reduced when designs used standardised, rather than self-designed measures, The implications for future meta-analyses and research in cooperative learning are explored.

Effects of peer network interactions on adolescent cannabis use

Purpose
This study capitalises on three waves of longitudinal data from a cohort of 4351 secondary school pupils to examine the effects on individuals’ cannabis use uptake of both peer cannabis use and position within a peer network.

Design/methodology/approach
Both cross-sectional and individual fixed effects models are used to estimate the effect on cannabis use of nominated friends’ cannabis use, of reciprocity and transitivity of nominations across the friendship cluster, and of interactions between these nominated friends. Post hoc analyses parsed the behaviour of reciprocating and non-reciprocating friends.

Findings
Cannabis use varied depending on the stability of friendship network and the degree of reciprocity and interconnectedness within the group. Behavioural influence was strong, but interaction effects were observed between the prevalence of cannabis use among friends, the structure of the friendship group and ego’s proximity to group members. These interactions demonstrate that behavioural influence is more salient in more cohesive groups. When reciprocating and non-reciprocating friends’ mean cannabis use were separated, influence from reciprocating friends was estimated at twice the magnitude of other friends.

Originality/value
While preventing any one individual from using cannabis is likely to have a multiplier effect on classmates, the bonds and interactions between classmates will determine which classmates are affected by this multiplier and the salience of that effect.

The Impact of Colleague Peer Review on the Radiotherapy Treatment Planning Process in the Radical Treatment of Lung Cancer

AIMS: Modern radiotherapy uses techniques to reliably identify tumour and reduce target volume margins. However, this can potentially lead to an increased risk of geographic miss. One source of error is the accuracy of target volume delineation (TVD). Colleague peer review (CPR) of all curative-intent lung cancer plans has been mandatory in our institution since May 2013. At least two clinical oncologists review plans, checking treatment paradigm, TVD, prescription dose tumour and critical organ tolerances. We report the impact of CPR in our institution.

MATERIALS AND METHODS: Radiotherapy treatment plans of all patients receiving radical radiotherapy were presented at weekly CPR meetings after their target volumes were reviewed and signed off by the treating consultant. All cases and any resultant change to TVD (including organs at risk) or treatment intent were recorded in our prospective CPR database. The impact of CPR over a 13 month period from May 2013 to June 2014 is reported.

RESULTS: One hundred and twenty-two patients (63% non-small cell lung carcinoma, 17% small cell lung carcinoma and 20% 'clinical diagnosis') were analysed. On average, 3.2 cases were discussed per meeting (range 1-8). CPR resulted in a change in treatment paradigm in 3% (one patient proceeded to induction chemotherapy, two patients had high-dose palliative radiotherapy). Twenty-one (17%) had a change in TVD and one (1%) patient had a change in dose prescription. In total, 6% of patients had plan adjustment after review of dose volume histogram.

CONCLUSION: The introduction of CPR in our centre has resulted in a change in a component of the treatment plan for 27% of patients receiving curative-intent lung radiotherapy. We recommend CPR as a mandatory quality assurance step in the planning process of all radical lung plans.

A Pilot Study of Reciprocal Peer Tutoring in Irish Medium Schools

A pilot study to investigate the effects of mathematics peer tutoring in Irish medium primary schools was undertaken. Five schools and 90 students took part in the pilot. Materials and resources that had previously been shown to work in English medium Scottish schools were translated into Irish by CCEA. Irish medium teachers attended three professional development days. Teachers implemented the peer tutoring techniques during mathematics lessons during a period of 16 weeks. Changes in attainment were measures with an Irish translation of the Scottish Survey of Achievement Mathematics Test. Results were positive. Student attainment was significantly raised during the 16-week implementation period by over one standard deviation. This equated to one-year’s worth of mathematics development during this time period. Results must be treated with caution. No control group was used in the pilot study. However, results are very promising and indicate that reciprocal role peer tutoring may be a useful pedagogy in Irish medium education. Further work would be required to establish this definitively.
