The use of the intensity gradient and average acceleration metrics to explore associations with BMI z-score in children

ABSTRACT

This study used the intensity gradient (IG) and average acceleration metrics to describe children’s activity profiles and explore associations with body mass index (BMI) z-score. Two hundred and forty-six children (n = 138 girls) aged 9.6 ± 1.4 years wore a wrist-mounted ActiGraph wGT3X-BT accelerometer for 7 days on their non-dominant wrist. Physical activity (PA) metrics captured included: the IG which describes the intensity distribution of accelerations across the 24 h monitoring period; average acceleration which provides a measure of the volume of activity; total moderate-to-vigorous PA (MVPA) and inactive time. Acceleration was averaged over 5s epochs. Finally, BMI z-score was calculated for each participant. Average acceleration was negatively associated with BMI z-score (p < 0.05) independent of age and gender but not IG. The IG was negatively associated with BMI z-score independent of potential correlates and average acceleration. Total MVPA was not associated with BMI-z score. The IG and average acceleration metrics may be used to explore the independent or cumulative effects of the volume and intensity distribution of activity upon measures of health and well-being in children to inform specific activity recommendations.     

Supporting programme teams to develop sequencing in higher education curricula

Curriculum sequencing is central to promoting a coherent student experience. Yet in the higher education context, the concept and practice of curriculum sequencing have not been fully explored. This research examined how seven programme teams approached the issue of sequencing across two Irish higher education institutions. A phenomenological approach was used to explore actions, challenges, and enhancers to sequencing. The three key themes emerging were: developing a collective philosophy; communicating the sequencing clearly; and, developing strong building blocks. Ideas are presented on how academic developers can work with academic staff to improve sequencing in their curricula.     

The Human Right of Home Education

Abstract

Homeschooling is legal and growing in many countries but is virtually forbidden by law in Germany and a few others. The European Court of Human Rights (ECtHR) has reviewed and upheld this ban. Is home education a human right? How do these courts employ their jurisprudence of proportionality to find banning home education does not violate relevant constitutional or human rights norms? Why does Germany forbid home education? Why does the ECtHR uphold Germany’s position? What does this divergence imply about the right of home education and the jurisprudence of these courts? If the promise of human rights is individual liberty then a system that justifies or endorses state control of education for the purpose of cultural conformity can be said to be far too statist for a free and democratic society. In this article, I argue that both the German Constitutional Court (FCC) and the ECtHR have adopted an approach to education rights that is profoundly mistaken. I conclude that home education is a right of parents and children that must be protected by every state. Nations that respect and protect the right of parents and children to home educate demonstrate a commitment to respecting human rights; nations that do not, such as Germany and Sweden need to take steps to correct their failure to protect this important human right.     

Segmented sedentary time and physical activity patterns throughout the week from wrist-worn ActiGraph GT3X+ accelerometers among children 7-12 years old

Background:This study examined the volume and patterns of physical activity(PA) and sedentary time(ST) across different segments of the week among boys and girls.Methods:A total of 188 children aged 7-12 years wore a wrist-mounted ActiGraph GT3 X+accelerometer for 7 days.Time spent in PA and ST was calculated using ActiLife software.The mean number of minutes of light PA,moderate PA,vigorous PA,moderate-to-vigorous PA(MVPA),and ST were calculated per weekday(before school,during school,and after school) and per weekend day(morning and afternoon-evening).Results:After school represented the greatest accumulation of ST compared with before school and during school segments.Boys engaged in225.4 min/day of ST(95% confidence interval(CI):216-235),and girls engaged in 222.2 min/day of ST(95%CI:213-231).During school,boys engaged in significantly more MVPA than girls(46.1 min/day(95%CI:44-48) vs.40.7 min/day(95%CI:39-43)).Across the whole weekday,boys participated in significantly more MVPA than girls(103.9 min/day(95%CI:99-109) vs.95.7 min/day(95%CI:90-101)).The weekend afternoon—evening segment represented the larger accumulation of ST,where boys were significantly more sedentary than girls(367.5 min/day(95%CI:353-382) vs.339.8 min/day(95%CI:325-355),respectively).Conclusion:Our findings suggest that children are highly sedentary and spend little of their time in school in MVPA,especially girls.Routine breaks in school elicit increases in light PA and MVPA.Future work should consider the use of more active breaks within school time to encourage PA and reduce ST.     

A new approach to researching school effects on higher education participation

A new approach to researching school effects on higher education participation is proposed here, which combines insights from the school effectiveness field of research with sociological theories and concepts of schooling. In doing so, it draws attention to some of the problems with the dominant approach often taken in this area and attempts to offer a more analytically precise way of measuring and explaining school effects on higher education choice. It will be argued that whilst past approaches can make it difficult to decipher school effects, the new approach proposed here provides greater understanding about the extent and nature of the school’s influence.     

Blended problem‐based learning for teacher education: lessons learnt

This paper explores case study research of the group process for teachers as learners in an Online Learning Module delivered in a blended problem‐based learning (PBL) environment. Blended learning, as the name suggests, consists of a blend of at least two pedagogical approaches: within the context of this research, blended learning is the integration of the PBL face‐to‐face learning in a classroom with an e‐learning environment. The 10‐week module was part of an accredited Postgraduate Diploma in Third Level Learning and Teaching for academic staff (lecturers, librarians, learning technology support staff) from a range of higher education institutions in the Republic of Ireland. This Postgraduate Diploma attracts academic staff keen to experience and implement a variety of pedagogical approaches within their own teaching. Over the four years of the module’s existence, there have been a wide variety of subject disciplines in higher education represented. This paper shares experiences and lessons learnt from the case study, and provides a set of recommendations for other teachers pursuing this form of blended PBL with students.     

Teaching citizenship in the faith school: qualitative evidence from separate schools in Northern Ireland

The purpose of this paper is to examine how teachers teach and students learn about citizenship education in two faith-based schools in Northern Ireland. The data show that participants in the Catholic school were confident in their own identity; teachers encouraged active engagement with contentious, conflict-related debates and students displayed empathy with other racial and religious groups. In the Protestant school, teachers avoided any reference to identity and conflict and students seemed to have limited knowledge of these issues. The findings emphasise the extent to which separate schools embody the cultural norms prevalent within each of the communities that they serve and reveal the influence which these norms have for teaching and learning about citizenship.     

Integrated schools and intergroup relations in Northern Ireland: the importance of parents

Background: Integrated schools were established in Northern Ireland in the early 1980s. With an explicit intention to build better relations between Catholics and Protestants, it has an intuitive appeal in a society which has long experienced sectarian division. Whilst the sector has attracted considerable research, less is understood about how parents’ perceive the approach adopted by schools to build intergroup relations.

Purpose: The present article seeks to address the gap in the literature by exploring parents’ views of integrated education. Drawing on theories of intergroup contact, the paper seeks specifically to explore how parents and head teachers perceive and negotiate the approach that the schools adopt to build intergroup relations.

Method: In an attempt to probe the deeper meanings that participants attach to integrated education, a qualitative research approach was adopted; semi-structured interviews were carried out with 17 parents and 2 head teachers in two integrated primary schools.

Findings: Through the data analyses, three main aspects were evident. Firstly, the study reveals something of the relational dynamic between head teachers and parents and the significance of this relationship for determining how intergroup relations are pursued in integrated schools. Secondly, it highlights the nebulous nature of identity salience and the practical challenges of making identity salient within mixed identity contexts. Finally, the study suggests the value of qualitative approaches for exploring intergroup contact initiatives.

Conclusions: Overall, the paper demonstrates the inherent challenges of establishing an integrated school where good relations will be developed when multiple interpretations of what constitutes an appropriate response to difference and diversity prevails.     

Teachers’ Willingness to Adopt Nature of Science Activities Following a Physical Science Professional Development

The major science education reform documents emphasize the need for K-12 students to have a robust understanding of nature of science (NOS), and inservice teachers consequently need to develop their NOS teaching repertoires. This study investigated the extent to which science teachers were willing to adopt new strategies and activities for teaching NOS in their classrooms. The participants were 36 elementary, middle, and high school teachers who were completing a year-long physical science professional development (PD) that included NOS instruction. Data sources consisted of surveys (teachers’ NOS views, teaching practices), collected work, and responses to post-PD follow-up questions. The professional development course was successful in that teachers incorporated many of these strategies and activities into their own practice. This study also endeavored to identify factors that facilitated the adoption of these new approaches to teaching NOS. While personal characteristics such as pre- or post-PD NOS understandings, NOS gains, and grade level taught were not related to the number of NOS activities incorporated, teachers from suburban and rural schools were significantly more likely to implement NOS activities.
