Physical Activity Performance of Focal Middle School Students

Histograms of push-ups and curl-ups from a sample of more than 9,000 students show periodic spikes at five and 10 unit intervals. This article argues that these spikes are related to focal points, a game theoretic concept popularized by Nobel Laureate Thomas Schelling. Being focal on one test makes one more likely to be focal on the other. Focal students (whose push-up score is a multiple of 5 and whose curl-up score is a multiple of 10) behave differently from their non-focal peers. They are more likely athletic, older, and male. Focal students, on average, did 2.2 more push-ups, 1.7 more curl-ups, and ran the mile 15 seconds faster than non-focal students, even controlling for these covariates of performance. By contrast, being focal on a single activity did not produce a statistically significant mile time difference. Students who systematically stop at focal outcomes appear differentially motivated toward physical activity performance.     

Validity and Reliability of the Global Physical Activity Questionnaire (GPAQ)

There is limited published validity and reliability evidence to support using the Global Physical Activity Questionnaire. Two studies were conducted to evaluate validity and reliability evidence for the Global Physical Activity Questionnaire. In Study 1: 69 adults completed the Global Physical Activity Questionnaire (three months apart; n?=?54), International Physical Activity Questionnaire, fitness and anthropometric measures. All participants wore a pedometer and 53 participants wore an accelerometer for seven days at baseline. In Study 2, 16 adults completed the Global Physical Activity Questionnaire 10 days apart. Global Physical Activity Questionnaire moderate and vigorous minutes were correlated with the accelerometer moderate (r?=?0.28) and vigorous (r?=?0.48) physical activity. The Global Physical Activity Questionnaire and International Physical Activity Questionnaire were related for sedentary behaviors (r?=?0.51), moderate-to-vigorous (r?=?0.48) and vigorous (r?=?0.63) PA. Global Physical Activity Questionnaire moderate-to-vigorous physical activity was associated with percent fat (r =??0.32), estimated VO₂ max (r?=?0.26), and step count (r?=?0.39). The Global Physical Activity Questionnaire demonstrated graded differences across categories for step count, body mass index, waist circumference, percent fat, fitness, and accelerometer measured activity. Short-term test–retest reliability (10 days) ranged from 0.83 to 0.96 while long-term reliability (three months) was 0.53 to 0.83. These data provide low-to-moderate validity and generally acceptable reliability evidence for the Global Physical Activity Questionnaire.     

Rationales and practices used by caring physical education teachers

This paper examines the reasons that physical education teachers exhibited caring behaviors during teaching. Four physical education teachers, identified as caring physical education teachers, were formally and informally interviewed and observed teaching. Data were analyzed using content analysis and inductive coding, and three themes emerged. The teachers (a) share similar beliefs about why it is important to be caring and had similar influences on their teaching conduct, (b) similarly believe that physical activity/physical education makes a difference in the lives of youth, and (c) share a common interest in broadening relationships with students. The results suggest that there are common reasons these caring teachers care for their students—in particular, personal biography seems to be a strong influence—and that more studies are needed to examine further these results and the relationship between the concept of caring and teaching.     

Sport Education as a pedagogical application for ethical development in physical education and youth sport

The purpose of this paper is to consider four pedagogical applications within the Sport Education model to examine the ways in which a young person can become a literate sports person and develop ethical behaviour through engagement in physical education and youth sport. Through a systematic review of the Sport Education research literature we present evidence to suggest that although notions such as inclusion, responsibility and ownership, personal and social development and social justice are part of the architecture of this pedagogical model, our findings show that rather than simply being caught, ethical conduct must be taught. Consequently, in the final part of the paper, we present four pedagogical applications within Sport Education that physical education teachers as well as youth sport practitioners and administrators may find useful to promote ethical development: (1) ethical contracts; (2) sports panels; (3) modified games; and (4) awards and rewards.     

Gender,Class and Outdoor Traditions in the UK and Norway

ABSTRACT

We report on three projects and an accompanying critical research agenda designed to establish and evaluate a new pedagogy in Australian physical education based on the sport education curriculum model first published by Siedentop et al. [Siedentop, D., Mand, C. & Taggart, A. (1986) Physical Education: Teaching and Curriculum Strategies for Grades 5‐12 (Palo Alto, Mayfield]. The projects, involving over 80 schools throughout Australia, are set in a context featuring an amalgam of postmodern youth culture, governmental inquiries and reports and the continuing difficulties facing physical educators in their workplaces. Against a backdrop of subject marginatyia, the projects’ findings have lent support to the proposition that it is dysfunctional programme structures (rather that deficits in teaching skills) that are most to blame in denying teachers access to significant subject matter learning targets. Our work presents evidence that the student‐centred, extended‐unit sport education curriculum model has the potential to be responsive to these challenges. It is conducive to ongoing school‐based professional and curriculum development, has led to widespread programme restructuring, has improved outcomes for many lower skilled students and has generally produced positive results for aspects of students’ social development. However girls tend still to be dominated by boys in particular sports. The model is positively affecting the career expectations of pre‐service students. As the model is already diffusing rapidly in Australian schools, there is a need to identify issues and chart an educational course for any further development.     

Improving the wind and temperature measurements of an airborne meteorological measuring system

The Aircraft Integrated Meteorological Measuring System 20 Hz(AIMMS-20) has been used by the Hong Kong Observatory(HKO),China in data collection for tropical cyclone situations over the South China Sea and windshear and turbulence measurement at the Hong Kong International Airport(HKIA).This paper discusses possible methods for further enhancing the quality of the wind and temperature measurements from the system.For wind measurement,the enhancement methods include:error modelling of the accelerometer(e.g.,bias offset and cross-axis rate sensitivity),global positioning system(GPS) phase lag consideration,better representation of the inertial measurement unit(IMU) velocity based on the GPS velocities and considering their location differences,consideration of the slower update of GPS velocity,and wing flexure.For temperature measurement,the methods include the consideration of the temperature sensor response and the sensor housing response.The results of typical flights using AIMMS-20 show that the accuracy of the wind and temperature data could be improved by 20%-30%.Though the discussion in the present paper is related mainly to a specific meteorological measuring system on a particular aircraft,the techniques so employed should be a useful reference for similar systems installed on other aircraft.     

Walking the Talk: Continuous Improvement of a Quality Management Field Exercise

This article provides results from a three semester case study of the pedagogical efficacy of an innovative quality management field exercise. A series of direct and indirect measures were used to assess the extent to which the field exercise met a set of learning objectives. The results indicate that the assessment framework is useful in identifying areas of improvement for course delivery. Finally, the results have been used to devise modifications to the course.
