Universal access to elementary schooling is a goal that was largely achieved in western democracies by the mid twentieth century. Yet, at the beginning of the twenty-first century, students’ access to schooling appears to be back on the agenda; this time, students themselves rather than our social systems are regulating their access to school. Increasingly, schools throughout Australia and in several other OECD countries are recording a worrying decline in student attendance in the compulsory years, prompting a certain amount of societal ‘fear’, ‘anxiety’ and ‘moral panic’. This paper reviews the literature on student attendance and absenteeism as a feature of contemporary schooling. It begins with an account of how this literature variously defines absenteeism – its discursive categories – and where it locates the ‘problem’. The ‘solutions’ that flow from these accounts are also explicated, specifically in relation to their regulatory effects on students and on the education they are offered. The paper’s critical reading of these problems of and solutions for student absenteeism seeks to highlight the institutional authoring of such student behaviour and of students as ‘other’. It also uncovers the silences in the literature, particularly in relation to cultural difference, student subjectivity and teacher pedagogy – what teachers are doing (and not doing) to/with students. The paper concludes that issues of low socio-economic status do not feature very loudly in the literature (and, we suspect, in practice), despite being strongly associated with students who respond to the demands and relevance of schooling by ‘talking with their feet’.

In the past decade, we have seen the well-established discourse of environmental education (EE) supplanted by that of education for sustainability (EfS). In some ways this change in terminology has been no more than a slogan change, with the actual educational practices associated with EfS little changed from those qualified by EE (Campbell and Robottom 2008). Environment-related education activities under both terms frequently focus on socio-scientific issues – which serve as the chief organising principle for a range of related curriculum activities – and are shaped by the particular characteristics of these issues. Socio-scientific issues are essentially constituted of questions that are philosophical as well as empirical in nature. Socio-scientific issues consist in contests among dissenting social, economic and environmental perspectives that rarely all align, giving rise to debates whose resolution is not amenable to solely scientific approaches. Socio-scientific issues, then, exist at the intersection of differing human interests, values and motivations and are therefore necessarily socially-constructed. An adequate educational exploration of these issues requires a recognition of their constructedness within particular communities of interest and of the limitation of purely applied science perspectives, and, in turn, requires the adoption of curricular and pedagogical approaches that are in fundamental ways informed by constructivist educational assumptions – at least to the extent that community constructions of socio-scientific issues are recognised as being shaped by human interests and social and environmental context. This article considers these matters within the context of examples of environment-related practice drawn from two geographical regions. The article will argue that a serious scientific element is both necessary and insufficient for a rigorous educational exploration of socio-scientific issues within either the EE or EfS discourses, and will consider some implications for professional development and research in this field.

Objective - To identify socio-demographic characteristics of children from socioeconomically disadvantaged neighbourhoods who meet physical activity and screen recommendations.
Method - Children aged 5–12 years (n = 373; 45% boys) were recruited in 2007 from socioeconomically disadvantaged urban and rural areas of Victoria, Australia. Children's physical activity, height and weight were objectively measured. Mothers reported their highest level of education, and proxy-reported their child's usual screen-time. Odds ratios (OR) and 95% confidence intervals (95% CI) examined odds of meeting physical activity (> 60 minutes/day) and screen (≤ 120 minutes/day) recommendations according to socio-demographic characteristics.
Results - Approximately 84% of children met physical activity and 43% met screen recommendations. Age was inversely associated with odds of meeting physical activity and screen recommendations, and overweight/obese status was associated with lower odds of meeting screen recommendations (boys: OR = 0.39, 95%CI = 0.16–0.95; girls: OR = 0.47, 95%CI = 0.26–0.83). Among boys, living in a rural area was positively associated with meeting screen recommendations (OR = 3.08, 95%CI = 1.42–6.64). Among girls, high levels of maternal education were positively associated with meeting screen recommendations (OR = 2.76, 95%CI = 1.33–5.75).
Conclusion - Specific socio-demographic characteristics were associated with odds of meeting physical activity and screen recommendations. Identifying factors associated with such ‘resilience’ among this group may provide important learnings to inform future physical activity promotion initiatives.

Diet quality indices reflect overall dietary patterns better than single nutrients or food groups. The study aims were to develop a measure of adherence with dietary guidelines applicable to child and adolescent populations in Australia and determine the association between index scores and food and nutrient intake, socio-demographic characteristics, and measures of adiposity. Data were analyzed from 4- to 16-y-old participants of the 2007 Australian Children’s Nutrition and Physical Activity Survey (n = 3416). The Dietary Guideline Index for Children and Adolescents (DGI-CA) comprises 11 components: 5 core food groups, wholegrain bread, reduced-fat dairy foods, extra foods (nutrient poor and high in fat, salt, and added sugar), healthy fats/oils, water, and diet variety (possible score of 100). The index criteria were age specific. The mean DGI-CA score was low (53.6 ± 0.4), similar between boys and girls, and differed by age; the youngest children scored higher than the oldest children (P < 0.0001). Higher DGI-CA scores were associated with lower energy intake, energy density, total and saturated fat, and sugar intake; higher protein, carbohydrate, fiber, calcium, iron, vitamin C, vitamin A, folate, phosphorous, magnesium, zinc, and iodine intakes; and a higher polyunsaturated:saturated fat ratio (P < 0.0001). DGI-CA scores were associated with socio-economic characteristics and measures of family circumstance. Weak positive associations were observed between DGI-CA score and BMI or waist circumference Z-scores in the 4- to 10-y and 12- to 16-y age groups only. This index is the first validated index in Australia and one of the few international indices to describe the diet quality of children and adolescents.

The objective was to study the multidimensional nature of the relationship between adult obesity (OB) and socio-economic status (SES),
using comprehensive indices of SES taken separately or synthesised in an overall index. A nationally representative sample of adults aged
18–79 years was taken from the French second National Individual Survey on Food Consumption (INCA 2) dietary survey (2006–07).
Weight and height were measured and OB defined as BMI $ 30 kg/m2. SES variables were reported in questionnaires and included
occupation, education and characteristics of household wealth. Composite indices of SES (household wealth and overall SES indices)
were computed by correspondence analysis, and relationships with OB were investigated with logistic regression analysis. In total, 11·8
(95% CI 10·1, 13·4) % of French adults were obese, without significant difference by sex. While no significant relationship was observed
in men, all SES indicators were inversely correlated to OB in women. Both education and the household wealth index were retained in the
stepwise multivariate model, confirming that different socio-economic variables are not necessarily proxies of each other regarding the OB
issue. On the other hand, ‘controlling for SES’ while including several measures of SES in multivariate models may lead to collinearity, and
thus over-adjustment. A more integrative approach may be to derive a synthetic index by including the SES factors available in a given
study. Beyond this methodological perspective, understanding how OB is related to the different dimensions of SES should help to
target the more vulnerable groups and increase the effectiveness of prevention.

This paper has been prepared to address the issues and questions of the theme ‘access, equity and socio-cultural issues’. Findings from two studies are reported. In the first study gender issues in mathematical learning environments when computers were used were investigated. In the second effective practices for teaching disadvantaged or marginalised students with digital technology are canvassed. Teaching for equity and social justice in the digital age is complex. Teachers need to be aware that their beliefs and classroom practices may exacerbate gender and cultural inequalities in mathematics learning. Approaches that are consistent with social-constructivist and democratic theories need further investigation.

This group of papers explores the development of student understanding and application of the discursive tools of science to reason in this subject, as the basis for classroom practices that parallel scientists’ knowledge production practices. We explore how this account of the disciplinary literacies of science can be enabled through effective pedagogies. The papers draw on research from Australia and Sweden that have overlapping agendas and theoretical perspectives including pragmatism (Peirce 1931-58; Dewey 1938/1997), social semiotics (Kress et al. 2001) and socio-cultural perspectives on language and learning (Lemke, 2004). The papers examine the role of language/multimodal representations in generating knowledge claims in science classrooms, the classroom epistemologies that support learning, and assessment practices from this perspective. A large body of conceptual change research has identified trenchant problems in conceptual learning in science, spawning long-standing and ongoing programs to identify pedagogies to address this. By redefining the problem in terms of language and representation, we aim to offer a way forward to support student engagement and learning in science.

This study analyses the evolution of socioscientific reasoning on sustainability, of French and Australian tertiary students exchanging ideas on a digital platform, concerning local (Australian, French) environmental SSIs, and global environmental SSIs. We explore how the exchange of arguments from various disciplinary and cultural perspectives, can promote reasoning about complex problem-situations in the environment. We develop a framework of reasoning, and show how it enables a productive analysis of the nature of the exchanges, and the quality of reasoning. We argue that such a strategy may improve epistemological training on the nature of science, and citizenship.

Introduction

Socio-economically disadvantaged women are at a greater risk of spending excess time engaged in television viewing, a behavior linked to several adverse health outcomes. However, the factors which explain socio-economic differences in television viewing are unknown. This study aimed to investigate the contribution of intrapersonal, social and environmental factors to mediating socio-economic (educational) inequalities in women's television viewing.
Methods

Cross-sectional data were provided by 1,554 women (aged 18-65) who participated in the 'Socio-economic Status and Activity in Women study' of 2004. Based on an ecological framework, women self-reported their socio-economic position (highest education level), television viewing, as well as a number of potential intrapersonal (enjoyment of television viewing, preference for leisure-time sedentary behavior, depression, stress, weight status), social (social participation, interpersonal trust, social cohesion, social support for physical activity from friends and from family) and physical activity environmental factors (safety, aesthetics, distance to places of interest, and distance to physical activity facilities).
Results

Multiple mediating analyses showed that two intrapersonal factors (enjoyment of television viewing and weight status) and two social factors (social cohesion and social support from friends for physical activity) partly explained the educational inequalities in women's television viewing. No physical activity environmental factors mediated educational variations in television viewing.
Conclusions

Acknowledging the cross-sectional nature of this study, these findings suggest that health promotion interventions aimed at reducing educational inequalities in television viewing should focus on intrapersonal and social strategies, particularly providing enjoyable alternatives to television viewing, weight-loss/management information, increasing social cohesion in the neighborhood and promoting friend support for activity.

The authors of this paper argue that human intuition alone cannot be relied upon for strategic decision making in today’s business environment and that quality data intelligence is an imperative. The proposed project described in this paper is research-in-progress, action design research (ADR), to implement an appropriate information systems (IS) enabling enhanced organisational decision making. ADR is a new research method that draws on action research and design research in an organisational setting. In phase 1 of the project, a sociotechnical ‘sense-making’ approach is used to gather and analyse information and decision needs in a not-for-profit (NFP) association, Connections ACT. In phase 2, requirements are designed and modelled to build a conceptual framework that guides NFPs in improving business performance and reporting capability. Phase 3 is the evaluative stage when the framework is reflected upon and refined, with intervention in the organisation’s processes as a promising outcome.

Objective Perceptions that fruit and vegetables are expensive have been found to be associated with lower consumption of fruit and vegetables among disadvantaged women; however, the determinants of these perceptions are relatively unknown. The purpose of the current paper is to examine whether perceived availability and quality of fruit and vegetables, and social support for healthy eating, are associated with perceptions of fruit and vegetable affordability among women residing in disadvantaged neighbourhoods.

Design Cross-sectional self-report survey.

Setting The study was conducted in Melbourne, Australia.

Subjects An Australian sample of 4131 women, aged 18–45 years, residing in neighbourhoods ranked in the lowest Victorian tertile of relative disadvantage by the Australian Bureau of Statistics, an index that considers aspects of disadvantage such as residents’ income, education, motor vehicle access and employment.

Results Results showed that irrespective of education, income and other key covariates, women who perceived poor availability and quality of fruit and vegetables in their local neighbourhood were more likely to perceive fruit and vegetables as expensive.

Conclusions Our results suggest that perceptions of fruit and vegetable affordability are not driven exclusively by lack of financial or knowledge-related resources, but also by women's psychological response and interpretation of their local nutrition environment.

The phenomenon of summer slide or setback has gained a great deal of attention in the USA. It is understood to account for as much as 80 % of the difference in achievement for students between low and high socio-economic families over their elementary schooling. In a mixed method longitudinal study of reforms in low socio-economic school communities in Victoria, Australia this phenomenon in the achievement growth of primary and secondary school students for both literacy and numeracy was identified. The longitudinal analysis of achievement data revealed decelerated growth during Terms 4 and 1, the spring and summer months in the Australian school calendar. In this article we present these findings and the reflections of Principals, literacy and numeracy leaders and coaches about these findings and their suggestions for action. We argue that reforming school practices during Terms 1 and 4 and developing a deeper understanding of students’ out-of-school learning and knowledge are essential for enhancing growth in achievement from September to March and for narrowing the achievement gap between marginalised and advantaged students. Further research of this phenomenon in the Australian context is needed.
