Item Describing objectively measured physical activity levels, patterns, and correlates in a cross sectional sample of infants and toddlers from South Africa(BioMed Central, 2017-12) Prioreschi, Alessandra; Micklesfield, Lisa K.; Brage, Soren; Hesketh, Kylie D.; Hnatiuk, Jill; Westgate, KateBackground: Physical activity is considered to have health benefits across the lifespan but levels, patterns, and correlates have not been well described in infants and toddlers under the age of two years. Methods: This study aimed to describe objectively and subjectively measured physical activity in a group of South African infants aged 3- to 24-months (n = 140), and to investigate individual and maternal correlates of physical activity in this sample. Infants’ physical activity was measured using an Axivity AX3 wrist-worn accelerometer for one week and the mean vector magnitude was calculated. In addition, mothers reported the average amount of time their infant spent in various types of activities (including in front of the TV), their beliefs about infants’ physical activity, access to equipment in the home environment, and ages of motor development milestone attainment. Analysis of variance (ANOVA) and pair-wise correlations were used to test age and sex differences and associations with potential correlates. Results: There were significant age and sex effects on the distribution of time spent at different physical activity intensities (Wilks’ lambda = 0.06, p < 0.01). In all cases, the trend was for boys to spend more time in higher intensity physical activity and less time in lower intensity activity than girls; and for time spent in higher intensity activities to be higher in older children. Time spent outside was higher in boys, and this reached significance at 18-months (F =3.84, p =0.02). Less concern around floor play was associated with higher physical activity at 12-months in females only (p = 0.03, r = 0.54), and no other maternal beliefs were correlated with physical activity. The majority (94%) of children were exceeding TV time recommendations. When controlling for age and sex, overall TV time was positively associated with BMI z-score (β=0.01, p = 0.05). Conclusion: This study is the first to show sex and age differences in the patterns of physical activity, and to report on objectively measured and maternal reported physical activity and sedentary behaviour in the first two years of life in South Africa infants. Infants and toddlers should be provided with as many opportunities to be active through play as possible, and TV time should be limited.Item The shift to outcomes based frameworks: key problems from a critical perspective(The Federal Institute for Adult Education (bifeb), 2011) Michael, Young; Allais, Stephanie MatselengThis paper takes a step back from the discussions and debates about qualifications frameworks per se, to think more broadly about the role of „qualifications“ in educational reform. The aims of the paper are to locate the reform of qualifications in its broader social and institutional context, to propose a way of conceptualizing the change from qualification systems as they have emerged historically to qualifications frameworks andoutcomes-based qualifications and to explore the tensions involved in the different goals that the introduction of a (National) Qualifications Framework – (N)QF will achieve. We argue that what is at stake in current reforms is the role of educational institutions in the education and training of the next generation, the balance between institution-based education and informal (in some cases work-based) learning, and the ways in which trust in qualifications is established and maintained. Our two-model analysis explores the balance between an emphasis on institutions and outcomes. This paper was written to provoke debate, and help all involved in researching qualifications frameworks to think more clearly about the issues.Item Practicalities of the National Development Plan: prospects and challenges, using the rural economy as a case study(University of the Witwatersrand, Johannesburg, 2017) Chilenga, Thokozani JThe National Development Plan 2030 (NDP) is arguably South Africa’s widest and most inclusive plan for economic and social development since 1994. It is evidence of the urgent need for development in South Africa, although its political will is yet to be determined. A test of the NDP’s strength is whether it can implement development beyond the document using existing state institutions and structures. This article argues that the NDP may be a prudent plan for South Africa to become a democratic developmental state. However, the plan fails to mention critical factors in its chapters that will affect the strength and achievability of the plan. The chapter on the rural economy is evidence of this major flaw of the plan as it fails to mention the role of women in the rural economy and the critical factor of traditional leadership and governance (TLG) in a meaningful way that will establish the connection between the two. Ultimately, the NDP does not recognise the interface between women, rural development and TLG, and this flaw will lead to complications in the implementation of the NDP unless it is clarified, refined and asserted.Item Will skills save us? Rethinking the relationships between vocational education, skills development policies, and social policy in South Africa(Elsevier, 2012-09) Allais, StephanieThis paper examines experiences with ‘skills development’ in South Africa to contribute to broader debates about ‘skills’ and the relationships between vocational education and development. Numerous policy interventions and the creation of new institutions and systems for skills development in South Africa are widely seen as having failed to lead to an increase in numbers of skilled workers. I analyze some of the underlying reasons for this by considering South African policies and systems in the light of research in developed countries. The dominant view in South African media and policy circles is that a skills shortage, coupled with an inflexible labour market, are the leading causes of unemployment. This has led to a policy preoccupation with skills as part of a ‘self-help’ agenda, alongside policies such as wage subsidies and a reduction of protective legislation for young workers, instead of collective responsibility for social welfare. Skills policies have also been part of a policy paradigm which emphasized state regulation through qualification and quality assurance reform, with very little emphasis on building provision systems and on curriculum development. The South African experience exemplifies how difficult it is to develop robust and coherent skills development in the context of inadequate social security, high levels of job insecurity, and high levels of inequalities. It also demonstrates some of the weaknesses of so-called ‘market-led’ vocational education.Item Educating for work in the time of Covid-19: moving beyond simplistic ideas of supply and demand(South African Comparative and History of Education Society (SACHES), 2016) Allais, Stephanie; Marock, CarmelThis article describes how the Covid-19 pandemic has been particularly negative for skill formation in South Africa but, at same time, there are high expectations for the technical and vocational education and training system to support economic recovery and individual livelihoods. We argue that many policy recommendations for how education can meet these expectations are trapped in a narrow and mechanistic notion of supply and demand. The knowledge and skills required to do work are not developed somewhere outside of the economy, and then ‘supplied’ to meet labour market ‘demand.’ Skill formation is embedded in a range of different economic, social, and political arrangements and systems. Policy notions of ‘supply and demand’ of skills also underestimate how the ability of education to prepare for work is shaped by the ways in which work is organised. We argue that both researchers and policymakers need to think about vocational skills development programmes within industry sector master plans that drive economic recovery. We provide ideas of how policymakers can think about education and work more holistically, and argue that the key move is away from market-based regulatory models and towards models focused on building institutional capacity.Item Claims vs. practicalities: lessons about using learning outcomes(2012) Allais, StephanieThe idea of learning outcomes seems to increasingly dominate education policy internationally. Many claims are made about what they can achieve, for example, in enabling comparison of qualifications across countries, improving the recognition of prior learning and improving educational quality. The claims made for the role of learning outcomes rest on the assumption that outcomes can be transparent, or that they can capture or represent the essence of what a learning programme or qualification represents. But in practice, either learning outcomes are open to dramatically different interpretations, or they derive their meaning from being embedded in a curriculum. In both instances, learning outcomes cannot play the roles that are claimed for them. I draw on insights from South Africa, where learning outcomes were a major part of curriculum and education policy reform. I suggest that outcomes cannot disclose meaning within or across disciplinary or practice boundaries. They did not enable the essence of a programme to be understood similarly enough by different stakeholders and they did not facilitate judgements about the nature and quality of education and training programmes. Learning outcomes do not carry sufficient meaning, if they are not embedded in knowledge within a curriculum or learning programme. But if they are thus embedded, they cannot play the roles claimed for them in assisting judgements to be made across curricula and learning programmes. The notion of transparency (or even, a more moderate notion of sufficient transparency) which proved unrealisable in practice is the basis of nearly all the claims made about what learning outcomes can achieve. In addition, the South African experiences demonstrated how outcomes-based approaches can distort education and training programmes, and lead to practical complexities, which are a direct consequence of the need for transparency, and its impossibility, and not (although this was probably also the case) the product of ‘poor implementation’ in South Africa.Item Labour market outcomes of national qualifications frameworks in six countries(Taylor and Francis Group, 2017) Allais, StephanieThis article presents the major findings of an international study that attempted to investigate the labour market outcomes of qualifications frameworks in six countries – Belize, France, Ireland, Jamaica, Sri Lanka, and Tunisia, as well as the regional framework in the Caribbean. It finds limited evidence of success, but fairly strong support for the frameworks. The continued popularity of qualifications frameworks as a reform mechanism seems to be symptomatic of the ways in which transitions from education to work are in flux in many countries, coupled with the fragmented and complex systems of vocational provision in some of the countries. Even where such systems are not overly complex they have weak and possibly weakening relationships with work. Insufficient differentiation of different types of frameworks by policy makers obscures these factors, leading to misleading ideas about what frameworks can do in general. Extending existing typologies for the analysis of qualifications frameworks the paper argues that the French framework, where labour markets were the most regulated and collective bargaining had the widest reach, had the clearest relationships between qualifications and work. However, the qualifications framework did not seem to be the cause, but rather the effect of such relationshipsItem An exploratory perspective of student performance and access to resources(Mediterranean Center of Social and Educational Research, 2014-11-01) Papageorgiou, E; Callaghan, C.WThis research investigated the relationships between potential constraints to students’ access to technological resources and student academic performance. Longitudinal data from 2010 (n=228), 2011 (n=340) and 2012 (n=347) from South African accounting students was used to test the relationships between technological resources access and student academic performance using correlation analysis, multiple linear regression analysis and factor analysis. Access to the latest software was found to be associated with student academic performance; a ‘digital divide’ between students may influence their academic performance. This research specifically identifies certain constraints potentially associated with a ‘digital divide’ that may influence student performance.Item An exploratory perspective of student performance and access to resources(Mediterranean Center of Social and Educational Research, 2014-11-01) Papageorgiou, E; Callaghan, C.WThis research investigated the relationships between potential constraints to students’ access to technological resources and student academic performance.

Cause specific Cox regression models were fitted and adjustments were made to accommodate a proportion of long term survivors. Methodologies were compared using ROC curves and area under the curves. The results show that survival methods perform better than logistic regression methods when modelling lifetime data in the presence of competing risks and in the presence of long term survivors.
