School based education programme to reduce salt intake in children and their families (School-EduSalt): cluster randomised controlled trial

Objective To determine whether an education programme targeted at schoolchildren could lower salt intake in children and their families. Design Cluster randomised controlled trial, with schools randomly assigned to either the intervention or control group. Setting 28 primary schools in urban Changzhi, northern China. Participants 279 children in grade 5 of primary school, with mean age of 10.1; 553 adult family members (mean age 43.8). Intervention Children in the intervention group were educated on the harmful effects of salt and how to reduce salt intake within the schools' usual health education lessons. Children then delivered the salt reduction message to their families. The intervention lasted for one school term (about 3.5 months). Main outcome measures The primary outcome was the difference between the groups in the change in salt intake (as measured by 24 hour urinary sodium excretion) from baseline to the end of the trial. The secondary outcome was the difference between the two groups in the change in blood pressure. Results At baseline, the mean salt intake in children was 7.3 (SE 0.3) g/day in the intervention group and 6.8 (SE 0.3) g/day in the control group. In adult family members the salt intakes were 12.6 (SE 0.4) and 11.3 (SE 0.4) g/day, respectively. During the study there was a reduction in salt intake in the intervention group, whereas in the control group salt intake increased. The mean effect on salt intake for intervention versus control group was -1.9 g/day (95% confidence interval -2.6 to -1.3 g/day; P<0.001) in children and -2.9 g/day (-3.7 to -2.2 g/ day; P<0.001) in adults. The mean effect on systolic blood pressure was -0.8 mm Hg (-3.0 to 1.5 mm Hg; P=0.51) in children and -2.3 mm Hg (-4.5 to -0.04 mm Hg; P<0.05) in adults. Conclusions An education programme delivered to primary school children as part of the usual curriculum is effective in lowering salt intake in children and their families. This offers a novel and important approach to reducing salt intake in a population in which most of the salt in the diet is added by consumers.

Inquiry-based learning in teacher education: a primary humanities example

Inquiry-based learning features strongly in the new Australian Humanities and Social Sciences curriculum and increasingly in primary school practice. Yet, there is little research into, and few exemplars of, inquiry approaches in the primary humanities context. In this article, we outline and explain the implementation of a place-based simulation as a vehicle for inquiry in a humanities subject in a teacher education course. Preliminary findings of surveys of pre-service teachers conducted pre and post the implementation of the inquiry model suggest increased engagement and enhanced learning outcomes. Further analysis is required in order to determine the depth of pre-service teachers’ understanding of inquiry approaches.

The place of place-based education in the Australian primary geography curriculum

The idea for this paper emerged from a recent qualitative investigation which examined the ways in which six Australian primary teachers conceptualised geography and geography teaching (Preston, 2014b). A finding of this research was a strong correlation between the breadth of geographical understandings and the years of experience and age of participants. For early career teachers, conceptions of geography were narrowly confined to information-oriented perceptions. Whereas, the two teachers, with more than 30 years in primary schools, portrayed much more complex understandings. Their conceptions depicted geography as process-oriented and in relational terms, that is, understandings of geography that recognise the interactions and interdependence of people and environments (Bradbeer, Healey, & Kneale, 2004). Both these experienced teachers were also committed to place-based, inquiry approaches to geography teaching and had been using placebased methodologies long before it became a new movement in education (Morgan, 2009, p. 521 ). This prompted me to question why geography education seldom features in discourses of place-based education and to contemplate the oft-cited argument (at least in the United States) that the recent focus on curriculum standards is incompatible with locally responsive curriculum (Jennings, Swidler, & Koliba, 2005).
In order to answer these questions, I explore the intersections and divergences between place-based education and geography education in the Australian context. Drawing on Smith's (2002) and Gruenewald's (2003) conception of place-based education, and the new. Australian geography curriculum document, I argue that primary geography education has strong synergies with place-based education methodologies and aims. I further suggest that a geographical perspective can augment placebased education to enrich and broaden students' understandings of the complex interactions between and within places. This argument is balanced with a critical examination of the practice of geography education acknowledging that the tradition of fieldwork might benefit from placebased education approaches that enable more embodied, socially engaged interactions with places. Thus, I contend, place-based education and geography education are mutually supportive and each can extend the other. The paper concludes with a reflection on the challenges in Australia in preparing primary teachers for the implementation of the new (place-based) geography curriculum.

Moderating effects of age, gender and education on the associations of perceived neighborhood environment attributes with accelerometer-based physical activity: the IPEN adult study

The study's purpose was to examine age, gender, and education as potential moderators of the associations of perceived neighborhood environment variables with accelerometer-based moderate-to-vigorous physical activity (MVPA). Data were from 7273 adults from 16 sites (11 countries) that were part of a coordinated multi-country cross-sectional study. Age moderated the associations of perceived crime safety, and perceiving no major physical barriers to walking, with MVPA: positive associations were only found in older adults. Perceived land use mix-access was linearly (positive) associated with MVPA in men, and curvilinearly in women. Perceived crime safety was related to MVPA only in women. No moderating relationships were found for education. Overall the associations of adults' perceptions of environmental attributes with MVPA were largely independent of the socio-demographic factors examined. These findings are encouraging, suggesting that efforts to optimize the perceived built and social environment may act in a socially-equitable manner to facilitate MVPA.
