Experiencing risk,surveillance, and prosumption: health and physical education students’ perceptions of digitised health and physical activity data

ABSTRACT

Digital technologies are now considered important in shaping young people's engagement in and with health and physical activity. Recent discussions show that the use of digital technologies to track health and fitness may over-emphasize the linear understanding of the body and health generally underpinned by Western health ideologies such as healthism. Other studies have shown the increased use of digital technologies in teaching Health and Physical Education (HPE) and as a means to enhance health and increase physical activity. Despite the opportunities and risks apparent in these studies, little is known about how HPE students make choices, negotiate, and resist or embrace the digitalisation of physical activity, exercise, and more broadly health. This study examines HPE students’ meaning making of risk and surveillance associated with the self-digitisation of exercise. The study further investigates how the concept of ‘prosumption’; the production, curation and consumption of self-data within the context of digitised health and physical activity, is understood. Based on the findings, we have constructed a typology of prosumers that can be used as a pedagogical device to illustrate the various kinds of subject positions students take up with digital technology in health and physical activity. This study extends the current understanding of prosumers by identifying the ‘ambivalent prosumer’. The results provide insights that have direct pedagogical implications in HPE teacher education specifically in the areas of knowledge production and consumption of knowledge through digital technology in health and physical activity.

Mixed messages: pre-service Health and Physical Education teachers’ understandings of health and the body and the expectations of the Australian curriculum

This paper explores how a cohort of pre-service Health and Physical Education (HPE) teachers from an Australian university describe and construct their understandings of health and the body. Given that the courses that these undergraduates take in their degree programme present different perspectives on health and the body, a relevant question is to what extent these perspectives adequately equip these future HPE teachers to successfully teach the recently released Australian HPE curriculum. The participants in this study were 14 pre-service teachers, 11 females and 3 males, aged between 18 and 26 at the time of the first interview. The data used for this paper were taken from a larger study and were generated through interviews, the analysis of two undergraduate course profiles and an analysis of the new National HPE curriculum. Results reveal that there are some dominant discourses in health-related courses that may have a significant impact on these students. The purpose of HPE, the role of the HPE teacher and the idea of the HPE teacher as role model are also discussed. The results suggest that pre-service teachers face several challenges and dissonances between what they learn during their undergraduate programme and what the Australian HPE curriculum expects them to teach. How pre-service HPE teachers think about and relate to health and the body is important in terms of how they think about their professional practice and the influence they may have on their future pupils.     

Visual and phonological coding in working memory and orthographic skills of deaf children using Chilean sign language

Deaf children can improve their reading skills by learning to use alternative, visual codes such as fingerspelling. A sample of 28 deaf children between the ages of 7 and 16 years was used as an experimental group and another sample of 15 hearing children of similar age and academic level as a control group. Two experiments were carried out to study the possible interactions between phonological and visual codes and working memory, and to understand the relationships between these codes and reading and orthographic achievement. The results highlight the relationship between dactylic and orthographic coding. Just as phoneme-to-grapheme knowledge can facilitate reading for hearing children, fingerspelling-to-grapheme knowledge has the potential to play a similar role for deaf readers.     

RESCUR Surfing the Waves: an evaluation of a resilience programme in the early years

ABSTRACT

RESCUR Surfing the Waves is a recently developed resilience curriculum for early years and primary schools in Europe. It seeks to develop in marginalized young learners the requisite competences needed to overcome the various challenges in their lives to achieve academic success and social and emotional wellbeing. The competences include developing a growth mindset, making use of one’s strengths, self-determination, effective communication skills and healthy relationships, and overcoming challenges and obstacles. This paper presents the findings of a study on the implementation of the programme in five kindergarten centres in Malta over a 1-year period. A pre- and post-intervention study in 20 classrooms (97 children) showed an improvement in resilience skills, prosocial behavior and learning engagement, but not in internalized and externalized problem behaviors. A small scale study in two nurture classes at two of the schools found similar findings. The findings suggest that there are indications that the programme as a proportionate universal intervention for early years leads to an improvement in social and academic behaviours, but more rigorous research is needed to substantiate these findings.     

Sesame street as a continuing experiment

After 22 years,Sesame Street continues to be a television experiment designed to prepare preschool children, especially poor inner-city children, for school. The success ofSesame Street can be attributed to the unique partnership the Children's Television Workshop forged early on between producers and researchers on the project. Three institutional mechanisms—curriculum seminars, theWriters' Notebook, and extensive child testing—create formal opportunities for producers and researchers to explore new topics and to learn more about preschool children and how they respond to the program. This article describes each of these mechanisms and presents a case study that exemplifies how researchers, producers, and writers worked together to developSesame Street's new geography curriculum.     

The Development of Science Education Research in Brazil and Contributions from the History and Philosophy of Science

Over the last 50 years a new research area, science education research, has arisen and undergone singular development worldwide. In the specific case of Brazil, research in science education first appeared systematically 40 years ago, as a consequence of an overall renovation in the field of science education. This evolution was also related to the political events taking place in the country. We will use the theoretical work of Rene Kaës on the development of groups and institutions as a basis for our discussion of the most important aspects that have helped the area of science education research develop into an institution and kept it operating as such. The growth of this area of research can be divided into three phases: The first was related to its beginning and early configurations; the second consisted of a process of consolidation of this institution; and the third consists of more recent developments, characterised by a multiplicity of research lines and corresponding challenges to be faced. In particular, we will analyse the special contributions to this study gleaned from the field known as the history and philosophy of science.     

Can high-intensity interval training improve physical and mental health outcomes? A meta-review of 33 systematic reviews across the lifespan

ABSTRACT

High-intensity-interval-training (HIIT) has been suggested to have beneficial effects in multiple populations across individual systematic reviews, although there is a lack of clarity in the totality of the evidence whether HIIT is effective and safe across different populations and outcomes. The aim of this meta-review was to establish the benefits, safety and adherence of HIIT interventions across all populations from systematic reviews and meta-analyses. Major databases were searched for systematic reviews (with/without meta-analyses) of randomised & non-randomised trials that compared HIIT to a control. Thirty-three systematic reviews (including 25 meta-analyses) were retrieved encompassing healthy subjects and people with physical health complications. Evidence suggested HIIT improved cardiorespiratory fitness, anthropometric measures, blood glucose and glycaemic control, arterial compliance and vascular function, cardiac function, heart rate, some inflammatory markers, exercise capacity and muscle mass, versus non-active controls. Compared to active controls, HIIT improved cardiorespiratory fitness, some inflammatory markers and muscle structure. Improvements in anxiety and depression were seen compared to pre-training. Additionally, no acute injuries were reported, and mean adherence rates surpassed 80% in most systematic reviews. Thus, HIIT is associated with multiple benefits. Further large-scale high-quality studies are needed to reaffirm and expand these findings.

Key points:

• HIIT may improve cardiorespiratory fitness, cardiovascular function, anthropometric variables, exercise capacity, muscular structure and function, and anxiety and depression severity in healthy individuals and those with physical health disorders.

• Additionally, HIIT appears to be safe and does not seem to be associated with acute injuries or serious cardiovascular events.

     

On the green and innovative side of trade competitiveness? The impact of environmental policies and innovation on EU exports

This paper aims at exploring how the export competitiveness of the European Union has been affected by environmental regulation and innovation. Starting from the Porter idea that environmental policies may foster international competitiveness by inducing technological innovation. We test both the strong and narrowly strong versions of the Porter hypothesis, in order to understand if such a virtuous cycle is confined into the environmental goods sector (respecting the narrow criterion) or it spreads out through the whole economic system. For this purpose we adopt a theoretically based gravity model applied to the export dynamics of five aggregated manufacturing sectors classified by their technological or environmental content.When testing the strong version, the overall effect of environmental policies does not seem to be harmful for export competitiveness of the manufacturing sector, whereas specific energy tax policies and innovation efforts positively influence export flows dynamics, revealing a Porter-like mechanism. When testing the narrowly strong version, environmental policies, but more incisively environmental innovation efforts, foster green exports. These results show that public policies and private innovation patterns both trigger higher efficiency in the production process through various complementarity mechanisms, thus turning the perception of environmental protection actions as a production cost into a net benefit.
