Needs of elementary and middle school teachers developing online courses for a virtual school

Eight teams of elementary and middle school teachers developed pilot online courses for the North Carolina Virtual Public School (NCVPS) in the USA. A qualitative case study with focus groups and a follow‐up survey helped to identify common needs of these non‐traditional course designers during course development efforts. Findings suggest virtual schools can better support non‐traditional course designers by providing leadership components such as technical expertise, regular feedback, and clear expectations, including an understanding of the target students. Findings further suggest designers need a range of bite‐sized professional development on replicating model courses, using course management systems, assessing learners online, designing with copyright and safety issues in mind, integrating Web tools, and developing course documentation for deployment. The article concludes with a discussion of support structures that may aid instructors tasked with online course development.     

A comparison of two methods for the calculation of accumulated oxygen deficit

The aim of this study was to compare accumulated oxygen deficit data derived using two different exercise protocols with the aim of producing a less time-consuming test specifically for use with athletes. Six road and four track male endurance cyclists performed two series of cycle ergometer tests. The first series involved five 10 min sub-maximal cycle exercise bouts, a VO2peak test and a 115% VO2peak test. Data from these tests were used to estimate the accumulated oxygen deficit according to the calculations of Medb? et al. (1988). In the second series of tests, participants performed a 15 min incremental cycle ergometer test followed, 2 min later, by a 2 min variable resistance test in which they completed as much work as possible while pedalling at a constant rate. Analysis revealed that the accumulated oxygen deficit calculated from the first series of tests was higher (P < 0.02) than that calculated from the second series: 52.3 +/- 11.7 and 43.9 +/- 6.4 ml x kg(-1), respectively (mean +/- s). Other significant differences between the two protocols were observed for VO2peak, total work and maximal heart rate; all were higher during the modified protocol (P < 0.01 and P < 0.02, respectively). Oxygen kinetics were also significantly faster during the modified 2 min maximal test. We conclude that the difference in accumulated oxygen deficit between protocols was probably due to a reduced oxygen uptake, possibly caused by a slower oxygen on-response during the 115% VO2peak test in the first series, and VO2-power output regression differences caused by an elevated VO2 during the early stages of the second series.     

Acceleratory match-play demands of a Super Rugby team over a competitive season

The match-play demands of rugby union have increased over time, and these demands should be quantified so as to provide a basis for optimal player loading during training. The primary aim of this article was to quantify accelerations, decelerations, impacts and aggregated body demands during the first half of match-play in a Super Rugby team. The secondary aim was to determine whether these characteristics are position-specific. Thirty-three players were monitored for 14 matches using global positioning system units with inbuilt microtechnology. Players were grouped according to positional roles and data were analysed for those who completed the entire duration of the first half of a given match. Forwards sustained more (d = 0.44) high-intensity impacts and greater (d = 0.26) aggregated body demands, while backs had more moderate (d = 0.55) and heavy accelerations (d = 0.76), and moderate (d = 0.23) and heavy decelerations (d = 0.54). These differences suggest that conditioning and recovery strategies should reflect the physical demands placed on players in different playing positions. Forwards should be conditioned with a focus on impacts and require longer recovery for the same duration of playing time, whereas conditioning for backs should emphasise rapid accelerations and decelerations.     

Exploring learning goals and assessment approaches for Indigenous health education: a qualitative study in Australia and New Zealand

In higher education, assessment is key to student learning. Assessments which promote critical thinking necessary for sustained learning beyond university are highly valued. However, the design of assessment tasks to achieve these types of thinking skills and dispositions to act in professional practice has received little attention. This research examines how academics design assessment to achieve these learning goals in Indigenous health education. Indigenous health education is an important area of learning for health practitioners to help address worldwide patterns of health inequities that exist for Indigenous people. We used a constructivist qualitative methodology to (i) explore learning goals and assessment strategies used in Indigenous health tertiary education and (ii) examine how they relate to higher education assessment ideals. Forty-one academics (from nine health disciplines) involved in teaching Indigenous health content participated in a semi-structured interview. Thematic analysis revealed learning goals to transform students’ perspectives and capacities to think critically and creatively about their role in Indigenous health. In contrast, assessment tasks encouraged more narrowly bounded thinking to analyse information about historical and socio-cultural factors contributing to Indigenous health. To transform students to be critical health practitioners capable of working and collaborating with Indigenous people to advance their health and well-being, the findings suggest that assessment may need to be nested across many aspects of the curriculum using a programmatic approach, and with a focus on learning to think and act for future practice. These findings accord with more recent calls for transformation of learning and assessment in health education.     

The Development of Nonsymbolic Probability Judgments in Children

Two experiments were designed to investigate the developmental trajectory of children's probability approximation abilities. In Experiment 1, results revealed 6- and 7-year-old children's (N = 48) probability judgments improve with age and become more accurate as the distance between two ratios increases. Experiment 2 replicated these findings with 7- to 12-year-old children (N = 130) while also accounting for the effect of the size and the perceived numerosity of target objects. Older children's performance suggested the correct use of proportions for estimating probability; but in some cases, children relied on heuristic shortcuts. These results suggest that children's nonsymbolic probability judgments show a clear distance effect and that the acuity of probability estimations increases with age.     

The presence of African American scholarship in early American criminology texts (1918–1960)

This paper reviews the results of a citation analysis conducted to determine the extent of references to African American scholarship in American criminology texts published between 1918 and 1960. The analysis showed that African American graduates from the University of Chicago's “Chicago School”, including Charles Johnson, E. Franklin Frazier, Monroe Work, and Earl R. Moses, were cited most often. They were usually cited in discussions of either race or culture areas and crime. African American scholars' discussions of the effects of social, economic, and political conditions such as slavery, segregation, racism and oppression on crime and criminality, especially among African Americans, were generally not cited. These findings suggest that while claims that African American scholarship cannot be found in mainstream publications might be somewhat overstated as they relate to early American criminology texts, the most important themes found in the writings of African Americans were excluded.     

Career choices and characteristics of African-American undergraduates majoring in criminal justice at historically black colleges and universities

Recent research has shown that African-Americans at historically black colleges and universities (HBCUs) have increasingly selected criminal justice/criminology as their field of study and career choice (Gabbidon and Penn 1999). To explore this trend, the authors replicated the work of Krimmel and Tartaro (1999) by surveying 284 undergraduate criminal justice majors at several HBCUs; the study was designed to investigate whether the students' reasons for selecting criminal justice as a major and career choice were in line with those of the earlier study conducted at predominantly white institutions. Our findings show that, while students at the two types of universities seem to select criminal justice as a major for the same reasons-including the interesting nature of the subject matter and its relevance to the real world-undergraduates at HBCUs reported stronger attitudes towards entering the career for economic as well as for altruistic reasons such as protecting the Constitution, fighting oppression, and helping people solve problems.     

Practice chains of production and consumption: mediatized practices across social fields

The argument developed in this paper is that a focus on practice provides some resolutions to methodological problems facing Bourdieuian scholarship in education. In order to develop Bourdieu's work on practice to account for the interactions between practices, this paper presents a conceptualization of practice as chains of production and consumption. The first part of the paper reviews the account of practice offered by Bourdieu both embedded in practice games and as field effects. The second part of the paper introduces practice chains of production and consumption as a way to conceptualize practice by drawing on a case involving print journalists’ involvement with policy makers over the course of an Australian policy review. The final section presents a discussion of this conceptualization and highlights the potential of the concept for further research in understanding the processes of educational policy development.
