Evaluating the Prediction of Maximal Heart Rate in Children and Adolescents

In this study, we compared measured maximal heart rate (HRmax) to two different HRmax prediction equations [220 — age and 208 — 0.7(age)] in 52 children ages 7-17 years. We determined the relationship of chronological age, maturational age, and resting HR to measured HRmax and assessed seated resting HR and HRmax during a graded exercise test. Maturational age was calculated as the maturity offset in years from the estimated age at peak height velocity. Measured HRmax was 201 ± 10 bpm, whereas predicted HRmax ranged from 199 to 208 bpm. Measured HRmax and the predicted value from the 208 — 0.7(age) prediction were similar but lower (p < .05) than the 220 — age prediction. Absolute differences between measured and predicted HRmax were 8 ± 5 and 10 ± 8 bpm for the 208 — 0.7 (age) and 220 — age equations, respectively, and were greater than zero (p < .05). Regression equations using resting HR and maturity offset or chronological age significantly predicted HRmax, although the R2 < .30 and the standard error of estimation (8.2-8.5) limits the accuracy. The 208 — 0.7(age) equation can closely predict mean HRmax in children, but individual variation is still apparent.     

Writing Stories to Enhance Scientific Literacy

In response to international concerns about scientific literacy and students’ waning interest in school science, this study investigated the effects of a science‐writing project about the socioscientific issue (SSI) of biosecurity on the development of students’ scientific literacy. Students generated two BioStories each that merged scientific information with the narrative storylines in the project. The study was conducted in two phases. In the exploratory phase, a qualitative case study of a sixth‐grade class involving classroom observations and interviews informed the design of the second, confirmatory phase of the study, which was conducted at a different school. This phase involved a mixed methods approach featuring a quasi‐experimental design with two classes of Australian middle school students (i.e., sixth grade, 11 years of age, n = 55). The results support the argument that writing the sequence of stories helped the students become more familiar with biosecurity issues, develop a deeper understanding of related biological concepts, and improve their interest in science. On the basis of these findings, teachers should be encouraged to engage their students in the practice of writing about SSI in a way that integrates scientific information into narrative storylines. Extending the practice to older students and exploring additional issues related to writing about SSI are recommended for further research.     

Time,space and the scholarly habitus: Thinking through the phenomenological dimensions of field

This article engages critically with Bourdieu’s notion of field. It questions the emphasis that Bourdieu places on what he terms ‘objective relations’ at the expense of the actual relations of those within a field. This not only involves relations between human actors but the interactions of humans with the non-human such as inanimate objects that over time, and in particular spaces, engender certain forms of embodiment. The intention of the article is to think through these phenomenological dimensions of field. It does this by firstly examining these issues as theoretical questions before siting them within an empirical context, revisiting data from an earlier study into the differential achievement of students of Chinese-, Pacific Islander- and Anglo-Australian backgrounds to ascertain the ways in which various micropractices performed within the home promote different dispositions to learning, some more and some less of value at school.     

Improvement Efforts in Rural Schools: Experiences of Nine Schools Receiving School Improvement Grants

Low-performing schools in rural settings can face challenges common to all struggling schools, such as low student motivation and maintaining a qualified teaching staff. However, aspects of rural schools’ settings, such as the distance from urban areas and the commute between the schools and the students’ and teachers’ homes, can exacerbate the challenges that rural schools face. This article focuses on the experiences of nine rural schools that were part of a study for the U.S. Department of Education on the school improvement process in a purposive sample of 35 schools receiving federal funds through the School Improvement Grants (SIG) program. In particular, it examines how respondents in the rural schools perceived that the schools’ rural setting influenced the schools’ challenges and improvement actions and presents findings on the recruitment and retention of teaching staff, an activity integral to school improvement efforts under SIG.     

The positions of primary and secondary schools in the English school field: a case of durable inequality

In interviews as part of a research study of structural reform in England, some tension between primary head teachers and their secondary peers was evident. This was symptomatic of a long-standing difference in status between the two phases. At a time when relations between stakeholders in local systems are subject to change, we seek to understand anew why that might be the case and how the tension we found was evidence of a current difference of power within interactions between representatives of the phases. We analyse differences of size, resources, workforce, pedagogy and history, and how they have resulted in different, and differently valued, practices and professional identities. We explore how attributes of the two phases have been counterposed and how, in complex interaction with wider discourses of politics, gender and age, this process has invested the differences with meanings and values that tend to relegate attributes associated with primary school. By focusing on the activation of cumulative inequality in interactions, we contribute a complementary perspective to studies of perceived relative status and highlight the implications for understanding school positioning in local arenas as the role of local authorities is reduced.     

Bicultural education policy in New Zealand

Abstract

Bicultural educational policy is part of a much broader ensemble of bicultural policies that were first developed by the Fourth Labour Government elected in 1984. These policies were an acknowledgement of, and response to, the historical injustices suffered by Māori people as a consequence of colonisation. Bicultural education policy is thought to be a means of addressing the ongoing challenge of educational underachievement of Māori students in the compulsory schooling sector. At present, the dominant discourse in New Zealand education frames the educational underachievement of Māori as a problem associated with cultural differences; however, this tends to obscure explanations that focus on socio-economic disparities. This paper shows how the dominant discourse relating to the underachievement of Māori students is established in policy and maintained through various auditing systems, and how this leaves little space for other explanations or solutions. The paper advocates a move away from an either/or approach to the problem of the educational underachievement of Māori and argues for greater critical engagement with bicultural education policy in order to open up space for conversations that address both the cultural and the socio-economic factors which may affect achievement.     

Pushing Past Clichés: Latina and Black Women’s Perceptions of the Dietetics Major and Profession during Career Exploration

Diversity in dietetics, like other health professions, has remained stagnant despite the increase of racial and ethnic minority groups in the United States. We examined how Latina and Black women, enrolled in a university outreach program, make sense of a critical media literacy program during career introduction to dietetics. Our findings revealed that the women did not identify with the dietetics major and profession due to stereotypical images. Cliché messages were used as a discourse method. The need to explore public discourse to understand identity formation and barriers to entry into health profession careers is discussed.     

Nameability supports rule-based category learning in children and adults

The present study tested the hypothesis that verbal labels support category induction by providing compact hypotheses. Ninety-seven 4- to 6-year-old children (M = 63.2 months; 46 female, 51 male; 77% White, 8% more than one race, 4% Asian, and 3% Black; tested 2018) and 90 adults (M = 20.1 years; 70 female, 20 male) in the Midwestern United States learned novel categories with features that were easy (e.g., “red”) or difficult (e.g., “mauve”) to name. Adults (d = 1.06) and—to a lesser extent—children (d = 0.57; final training block) learned categories composed of more nameable features better. Children's knowledge of difficult-to-name color words predicted their learning for categories with difficult-to-name features. Rule-based category learning may be supported by the emerging ability to form verbal hypotheses.     

Twins with autism: utilising video feedback to improve job‐related behaviours

Employment for individuals with autism spectrum disorders (ASD) is a significant factor in assuring quality of life in adulthood. The research reported in this article examines the effectiveness of video feedback (VFB) in improving the job‐related behaviours of twin adolescents with ASD and learning disabilities. The targeted behaviours included active engagement, decision‐making, responding to others, hygiene, and transition making. A within‐participant multiple‐probe design across targeted job behaviours, replicated across two participants, was used. The experimental phases of the design consisted of (A) baseline, (B) VFB + job coach evaluation, (C) VFB + concurrent job coach and self‐evaluation, and (A) maintenance. Using a modified Behavioral Observation of Students in Schools (BOSS) form broken into one‐minute intervals, job coaches evaluated participants on job‐related behaviours. Data gathered shows that VFB significantly impacted active engagement, responding to others, hygiene and transitioning. Decision‐making was least impacted by the interventions. The use of VFB is one way that job‐related behaviours of adolescents with ASD and other disabilities can be positively influenced.
