Physical activity levels of children during school playtime

School represents a suitable setting for intervention programmes aiming to promote physical activity to benefit health. During the school day, physical education and school playtime offer children regular opportunities to engage in physical activity. However, there is growing concern that, internationally, curricular time allocated to physical education is not meeting statutory guidelines. The effectiveness of the playground environment to promote physical activity has been considered as a complementary setting to physical education.

Physical activity guidelines state that children should engage in at least 1 hour of moderate intensity physical activity a day. Currently no empirically tested guidelines exist for physical activity levels during playtime. However, studies cited in this article indicate that playtime can contribute between 5-40% of recommended daily physical activity levels when no interventions have been utilised.

The limited school-based investigations that have been reported in the literature suggest that boys engage in more physical activity during playtime than girls. Studies that have implemented intervention strategies in order to promote physical activity levels indicate that playtime can substantially contribute towards daily optimal physical activity guidelines. Energy expenditure and physical activity levels have increased during playtime following the implementation of playtimebased interventions. In order to advance knowledge of children's physical activity during playtime, a number of key issues for consideration in future research are detailed. Research on children's use of playtime to be physically active and the extent of the contribution of playtime to daily physical activity guidelines is warranted.

Engineering education for primary school students

There have been a number of recent state and national reports noting the reduction in the numbers and calibre of students seeking to enter engineering education. Contributing reasons identified for this include the poor image of the profession generally, and that engineering is poorly understood in schools. The recent review of science and technology in primary schools identifies that primary school science and technology education needs to be improved, and that technology education is given significantly less time than science education in primary schools. It is clear that there are no short-term solutions to increase the number and calibre of engineering undergraduates. Improvements will only come when the community at large is better informed about the nature of engineering, and values more highly the contributions of the profession. This paper reports on a state-wide, Victorian engineering awareness competition organised by the Geelong Group of the IEAust in 1996. The results of the awareness competition are presented and its effectiveness is evaluated. Further consideration is given to factors contributing to career choice and the time at which students begin making this decision.

Utilizing and adapting leisure constraints models to enhance 'short-break' vacations : case study of Melbourne, Australia

Short-break tourism is likely to continue as a popular vacation for time-, income- and special interest conscious tourists. With the competition for visitors, destinations need to consider the constraints and facilitators associated with tourist decision-making for short-break vacations. This study presents the application of a leisure model toward better explaining such vacation choices. This study found key constraints, such as time and awareness, inhibited visitors from visiting attractions. The importance and influence of word-of-mouth recommendations plays a key role in gaining the attention of future visitors.

Longitudinal study of declarative and procedural memory in primary school-aged children

This study examined the development of declarative and procedural memory longitudinally in primary school-aged children. At present, although there is a general consensus that age-related improvements during this period can be found for declarative memory, there are conflicting data on the developmental trajectory of the procedural memory system. At Time 1 children aged around 5 years were presented with measures of declarative and procedural memory. The tasks were then administered 12 months later. Performance on the declarative memory task was found to improve at a faster rate in comparison to the procedural memory task. The findings of the study support the view that multiple memory systems reach functional maturity at different points in development.

The role of NCCP time for enhancing children's creativity in technology

The focus of our research project was the question Can children‘s creativity be enhanced by including a period of non-conscious cognitive process (NCCP) time? During this non-thinking time the brain makes connections between independent ideas, forgets inappropriate responses, and makes available more relevant responses for problem solving. The research generated cases of several primary school classrooms as the teachers incorporated NCCP time in their design technology sessions. Children were observed and teachers interviewed about their perceptions of children‘s creativity as the children designed and produced recycling devices. The cases revealed an optimum time frame of several days for nonconscious cognitive processing. These findings have implications for teachers of technology who assign the same day and time each week for technology learning. During the non-task time, which included the NCCP time, children were able to discuss their ideas with family members. As children learn in socio-cultural contexts, these discussions can be fruitful. The teachers indicated that peer discussions also played an important role after the generation of designs.

Overweight and obesity in infants and pre-school children in the European Union : a review

The objective of this study was to synthesize available information on prevalence and time trends of overweight and obesity in pre-school children in the European Union. Retrieval and analysis or re-analysis of existing data were carried out. Data sources include WHO databases, Medline and Google, contact with authors of published and unpublished documents. Data were analysed using the International Obesity Task Force reference and cut-offs, and the WHO standard. Data were available from 18/27 countries. Comparisons were problematic because of different definitions and methods of data collection and analysis. The reported prevalence of overweight plus obesity at 4 years ranges from 11.8% in Romania (2004) to 32.3% in Spain (1998–2000). Countries in the Mediterranean region and the British islands report higher rates than those in middle, northern and eastern Europe. Rates are generally higher in girls than in boys. With the possible exception of England, there was no obvious trend towards increasing prevalence in the past 20–30 years in the five countries with data. The use of the WHO standard with cut-offs at 1, 2 and 3 standard deviations yields lower rates and removes gender differences. Data on overweight and obesity in pre-school children are scarce; their interpretation is difficult. Standard methods of surveillance, and research and policies on prevention and treatment, are urgently needed.

Placing parks on the tourism agenda : promoting Melbournes' metropolitan parks to metropolitan and regional Victorian visitors

This study establishes a strategy aimed at raising interest in visiting Melbourne’s metropolitan parks based upon interviews and focus group responses in both regional Victoria and Melbourne. As the majority of regional visitors planning a short-break collect their information prior to departure, park information needs to be available before they embark. Whilst visiting Melbourne, regional visitors agreed that they would utilise local knowledge of their host to fill any of their limited spare time. Melbournians should be seen as a potential prime source of information for visitors, but this study found that many Melburnians were often unaware of local attractions. Consequently, part of the strategy to raise interest in visiting Melbourne’s parks must be targeted at Melburnians. This leads to the conclusion that a well informed host is the key to increased visitation
to metropolitan parks.

A new unit root test with two structural breaks in level and slope at unknown time

In this paper, we propose a new augmented Dickey–Fuller-type test for unit roots which accounts for
two structural breaks. We consider two different specifications: (a) two breaks in the level of a trending data series and (b) two breaks in the level and slope of a trending data series. The breaks whose time of occurrence is assumed to be unknown are modeled as innovational outliers and thus take effect gradually. Using Monte Carlo simulations, we showthat our proposed test has correct size, stable power, and identifies the structural breaks accurately.

Differences in physical activity during school recess

BACKGROUND: School recess provides a daily opportunity for physical activity engagement. The purpose of this study was to examine physical activity levels during recess by gender, ethnicity, and grade, and establish the contribution of recess to daily school physical activity levels.
METHODS: Two hundred and ten children (45% boys) from grades 3 to 6 in 4 elementary schools had their physical activity during school quantified using uni-axial accelerometry every 5 seconds for 5 consecutive school days. Data were collected in fall 2009. The proportion of time spent engaged in physical activity during daily school recess was determined using existing age-appropriate cutpoints. The relative contribution of recess to school day physical activity was also determined.
RESULTS: Boys were more active than girls during recess. Girls engaged in more sedentary activity than boys. No main effects for ethnicity were observed. Children in grades 3 and 5 were more active than children in grades 4 and 6. Recess contributed 17.9% and 15.5% toward boys’ and girls’ school day moderate-to-vigorous physical activity, respectively.
CONCLUSION: Children engaged in physical activity during recess, though interventions may be needed to increase the intensity of activity in this context.

Supporting ICT based pedagogies in science in rural school settings

Recent research has demonstrated a significant disadvantage for rural teachers in a variety of aspects of ICT use. This context provides a backdrop for two professional learning programs designed to support ICT-based pedagogies in teaching science in Victorian rural primary and secondary schools. In both programs the school-based workshops initiated a community of learners supported with online web-presence. One program used an intensive five-day workshop focused on developing teachers’ knowledge, pedagogical expertise and leadership skills in embedding ICT into classroom practice. The second program provided a one-day workshop focused on integrating ICT skills in teaching science. Factors that affected the uptake of ICT included the considerable diversity in ICT availability and use, teacher competence, lack of support in schools, and online support. To redress rural disadvantage in ICT use, school commitment and focused leadership were identified as central to programs that supported and developed teacher skills and pedagogies over time.

University dreams start in primary school

Up to 40 per cent of first-year undergraduates first consider university in primary school.

The finding, as part of a large-scale survey of 55,000 students in 55 institutions, has given universities quantitative evidence for the first time that young students are highly receptive to the notion of attending university.

Creating a dialogue across time in Athens : the new Acropolis museum and the Parthenon

A visit to the New Acropolis Museum in Athens, Greece, in late June 2010 set in train a number of questions and inspired a research project to begin to unravel something of the complex relationship between ancient and modern architecture on the Athenian Acropolis. Research was guided by the question: how does the contemporary museum, designed by Swiss born architect Bernard Tschumi in collaboration with local Greek architect Michalis Photiadis relate to the ancient Acropolis and the fifth century BC Parthenon, whose sculptures it was to house? A critical literature review was augmented by design analysis and field experience. This paper documents the resulting critical thematic investigations of the Parthenon, the Acropolis and the New Museum through siting, materiality and light, alignment, visual connections, through exploitation of the unique Attic light, orchestrated movement and considered juxtapositions. Research has revealed that Tschumi’s deliberate strategy of creating a dialogue between his building and the ancient monuments holds the key to his design intent, to creatively exploring contemporary architecture at the edge of such a physically and culturally dominant ancient plateau.

Arresting the decline in senior school chemistry

Enrolments in Australian Year 11 and year 12 chemistry are declining. In 1992, 23% of Australian year 12 students studied chemistry, decreasing to 18% in 2010. For science as a whole, the decrease is even more dramatic, from 94% to 51%. The decrease is slowing, but is continuing.
How should we respond to the report? Firstly, we should realise that it is not all gloom and doom. Secondly, education is not solely the responsibility of curriculum authorities and teachers. Each RACI member can communicate, inform and generally educate the wider community about the excitement and value of chemical science. Just a couple of hours of your time is not a panacea, but it can still make long-lasting impacts and affect career choices: even the largest beach consists of tiny individual grains of sand.
