The significance of faith for Black men's educational aspirations

It is uncontested that British African Caribbean men are minimally represented in elite UK higher education institutions. Even as data demonstrates that African Caribbean males are more likely to study further education than White males 1 1 Research indicates that the proportion of UK‐domiciled Black students pursuing higher education degree courses has increased since the academic year 2003/04 (ECU, 2014 ).
and that the proportion of UK ‐domiciled Black students pursuing higher education has increased since the 2003/04 academic year (ECU , 2014), the representation of Black students throughout the Russell Group remains low. 2 2 It is important to acknowledge that on the whole, undergraduate Black students are over‐represented in higher education and in 2012/13 experienced the largest increase in the proportion of all BME students attending university to 6.3% (ECU, 2014 , p. 114). However, the majority of this increase in Black student representation is accounted for in non‐Russell Group institutions, particularly at the less prestigious universities that comprise the Million+ Group. The Million+ Group comprises the following universities: Abertay University, Anglia Ruskin University, Bath Spa University, University of Bedfordshire, University of Bolton, Canterbury Christ Church University, University of Cumbria, University of East London, Edinburgh Napier University, London Metropolitan University, London South Bank University, Middlesex University, Staffordshire University, University of Sunderland, University of West London, University of the West of Scotland and Southampton Solent University ( www.millionplus.ac.uk/who-we-are/our-affiliates/ ).
Less than 3% of the entire Russell Group's student population comprised British African Caribbean students in 2011/12 and 2012/2013 (ECU , 2013, p. 203; ECU , 2014, p. 358). However, according to the 2011 Census, ‘Black’ people represent 5.5% (3.1 million) of the total UK population (ONS , 2015). For the few Black men who are successful in attaining acceptance at these exclusive universities, to what assets or capitals do these young men attribute their ability to get to and successful graduate from these institutions? Interviews with 15 Black male students who attended Russell Group universities in England and Wales were analysed and several ‘capitals’ or resources were identified as beneficial to their ability to succeed. Drawing on Bourdieu's work on cultural and social capital, this paper advances the concept of ‘faith capital’ as a unique recognised asset that six of the participants described and reflected upon as being influential on their academic trajectories. Based on findings from the ESRC ‐funded research Exploring the narratives of the few: British African Caribbean male graduates of elite universities in England and Wales , this paper discusses these six participants’ accounts of their higher education journeys in relation to how they identified faith as a resource that was influential to their academic success.

This is Not an Article: a reflection on Creative Research Dialogues (This is Not a Seminar)

Abstract

This is Not a Seminar (TINAS) is a multidisciplinary forum established in 2012 at Edith Cowan University (ECU) in Australia to support practice-led and practice-based Higher Degree by Research students. The Faculty of Education and Arts at ECU includes cohorts of postgraduate research students in, for example, performance, design, writing and visual arts. We established the TINAS programme to assist postgraduate research students in connecting their creative practices to methodological, theoretical and conceptual approaches whilst fostering an atmosphere of rapport across creative disciplines. The pilot programme conducted for six months in 2012 comprised dialogues with experienced creative researchers; critical reading sessions on practice-led theory; and workshops in journaling, ethics and copyright. This article is a reflection on the strengths and limitations of TINAS and future projections. More than an additional teaching and learning service, the programme has become a vital forum for creative dialogue.
