Test–retest reliability of a battery of field-based health-related fitness measures for adolescents

Abstract

The main aim of this study was to determine the test–retest reliability of existing tests of health-related fitness. Participants (mean age 14.8 years, s = 0.4) were 42 boys and 26 girls who completed the study assessments on two occasions separated by one week. The following tests were conducted: bioelectrical impedance analysis (BIA) to calculate percent body fat, leg dynamometer, 90° push-up, 7-stage sit-up, and wall squat tests. Intra-class correlation (ICC), paired samples t-tests, and typical error expressed as a coefficient of variation were calculated. The mean percent body fat intra-class correlation coefficient was similar for boys (ICC = 0.95) and girls (ICC = 0.93), but the mean coefficient of variation was considerably higher for boys than girls (22.2% vs. 12.2%). The boys' coefficients of variation for the tests of muscular fitness ranged from 9.0% for the leg dynamometer test to 26.5% for the timed wall squat test. The girls' coefficients of variation ranged from 17.1% for the sit-up test to 21.4% for the push-up test. Although the BIA machine produced reliable estimates of percent body fat, the tests of muscular fitness resulted in high systematic error, suggesting that these measures may require an extensive familiarization phase before the results can be considered reliable.     

Double Jeopardy: Testing the Effects of Multiple Basic Skill Deficiencies on Successful Remediation

Prior research has established that the depth and breadth of remedial need in basic skills (math and English) exhibited by a student at college entry are strongly and negatively associated with the likelihood of achieving college-level competency in those subjects (i.e., successful remediation). This well-documented finding is built upon a body of work employing either simple bivariate analyses or regression analyses that assume additive effects. Yet, there are reasons to suspect that multiple basic skill deficiencies, rather than exhibiting additive effects alone, may exhibit a negative multiplicative interaction effect on the likelihood of successful remediation. In this research, I test the hypothesis that the negative effect of math deficiency increases in magnitude with decreasing English competency. Although the data support this hypothesis, I find that this interaction does not have substantive importance in the face of the powerful direct effect of math deficiency on the likelihood of successful remediation in math.

PUBLIC APPROVAL OF ENVIRONMENTAL PROTECTION AND OTHER NEW SOCIAL MOVEMENT GOALS IN WESTERN EUROPE AND THE UNITED STATES

The environmental movement is one of the most successful socialmovements of the twentieth century, and a key reason for itssuccess has been strong public approval of the movement's goalof environmental protection. This paper reports cross-nationaldata on public approval of environmental protection relativeto approval of the goals of other major ‘new social movements’—theanti-nuclear power movement, the nuclear disarmament movement,the women's movement, the human rights movement and the animalrights movement—in Western Europe and the United States.The data come from a 1990 ‘lifestyles and attitudes’survey conducted by Gallup for Reader's Digest, based on nationallyrepresentative samples in the United States and seventeen Europeannations, and show higher public approval for environmental protectionthan for the goals of other new social movements.     

An exploration of teacher's use of iPads for students with learning support needs

This project explored how iPads were being used in a range of K‐12 schools to support the learning of students with a range of learning support needs. Groups of teachers (and other professionals) from the USA, Canada, Australia and the UK were invited to complete an online survey focused on the use of iPads in their classrooms, perspectives of their skill level, and how their school and school districts support the use of iPads. The survey focused on iPad use in classrooms (curriculum and skills); teachers’ skill levels; whether iPads are addressed in the Individualised Education Program (IEP); the systemic support for the iPads; and the perceived benefits and barriers. The results reveal that respondents are using iPads across many areas of the curriculum, which affirms the research in the emerging literature base. However, there are teacher reported differences in the manner and scope of iPad use in the classrooms and also the integration of the iPad in the IEP. The research also highlights variability in reported skill level for the iPad and an increased need for enhanced systemic support, such as training, funding, technical support and administrative support for the use of the iPad as a pedagogical tool.     

“Things your history teacher won't teach you: Science edition”: Black women science teachers as anti-racist teachers

Marginalized communities cannot and do not have decontextualized experiences with how socioscientific issues, such as exposure to COVID-19 as frontline essential workers, high Black infant mortality rates, air pollution leading to respiratory problems, and other issues, affect their communities. As PreK-12 science teachers and teacher educators strive to dismantle oppressive practices in their classrooms and curriculum, it would be helpful to learn from Black women science teachers who have been engaging in anti-racist practices before the racial awakenings of Summer 2020. In this study, three different virtual focus groups, or Sista Circles, were conducted with 18 Black women secondary science teachers. Ranging from 1 to 22 years of experience, Black women teachers across the country and international participants in Canada and Qatar participated in the Sista Circles. From intersectional qualitative analysis and narrative inquiry, the findings of the study reveal that Black women science teachers enact anti-racist science teaching by bringing something new to the community; using NGSS standards within the context of the community; teaching at the intersection of history, culture, and science learning and teaching; and building critical consciousness in the science classroom. Furthermore, the findings of the study have implications for the use of anti-racist frameworks within the context of science education that were authentically the practices of the Black women in the study. This study offers insights into how the critical consciousness of Black women teachers can be represented in the science classroom even in times of nonsupport from peers and administration. The power and necessity of Black women teachers are paramount in science classrooms specifically because of the neutral, apolitical ways science teaching has been approached in the past. The narratives and stories shared here exemplify how Black women science teachers transform science teaching and learning by displaying various acts of Criticality.     

Meeting the highly qualified teachers challenge

The moulding of the future of a nation depends on the teachers and the education they provide in schools. Research evidence from the US. National Assessment of Educational Progress (NAEP) confirms this to be the case. Quantitative analysis of data indicates that measures associated with pre-service teacher preparation are by far the strongest correlates of student achievement (Darling-Hammond 2000). The research report of Wilson, Floden, and Ferrini-Mundy (2001) also suggests a strong relationship between teacher preparation and teacher effectiveness. Other research studies similarly indicate that differences in teacher quality are the most crucial for student achievement when compared with variables such as class size, streaming, or the amount of homework (Anderson & Helms 2001; Mendro 1998; Powell & Anderson 2002; Rivkin, Hanushek & Kain 2001; Saunders & Horn 1994; Strong & Tucker 2000) as possible contributory factors. In the pursuit of improved student achievement, we therefore need to examine seriously the role of teacher variables, ranging from teacher qualifications and their subject matter knowledge, to what motivates them to take up teaching as a career and as a consequence, how they teach in classrooms.     

The pains of imprisonment: Exploring a classic text with contemporary authors

While classic texts on the prison have long been an important resource for those teaching courses on corrections, prison life has changed dramatically since many of these works were written. For this reason, some instructors may choose to drop classic texts in favor of more recent works. This essay examines recent firsthand accounts of prison written by Ted Conover, Victor Hassine, and Leonard Peltier and argues that such works may be used in conjunction with classic texts to provide students with an exciting, contemporary, and theoretically sophisticated account of prison life. By comparing these recent works to a particular classic text, Sykes's Society of Captives, this essay illustrates this potential for symbiosis and demonstrates some of the ways in which new works provide opportunities to extend our understanding of the classics. When used with classic texts, recent firsthand accounts offer instructors opportunities to illustrate and explain the significance of abstract concepts, to examine issues of continuity and change in corrections theory, and to encourage critical thinking on important issues.
