The effect of two different 18-week walking programmes on aerobic fitness,selected blood lipids and factor XIIa

Abstract

The purpose of this project was to evaluate the utility of low- and high-repetition maximum (RM) strength tests used to assess rowers. Twenty elite heavyweight males (age 23.7 ± 4.0 years) performed four tests (5 RM, 30 RM, 60 RM and 120 RM) using leg press and seated arm pulling exercise on a dynamometer. Each test was repeated on two further occasions; 3 and 7 days from the initial trial. Per cent typical error (within-participant variation) and intraclass correlation coefficients (ICCs) were calculated using log-transformed repeated-measures data. High-repetition tests (30 RM, 60 RM and 120 RM), involving seated arm pulling exercise are not recommended to be included in an assessment battery, as they had unsatisfactory measurement precision (per cent typical error > 5% or ICC < 0.9). Conversely, low-repetition tests (5 RM) involving leg press and seated arm pulling exercises could be used to assess elite rowers (per cent typical error ≤ 5% and ICC ≥ 0.9); however, only 5 RM leg pressing met criteria (per cent typical error = 2.7%, ICC = 0.98) for research involving small samples (n = 20). In summary, low-repetition 5 RM strength testing offers greater utility as assessments of rowers, as they can be used to measure upper- and lower-body strength; however, only the leg press exercise is recommended for research involving small squads of elite rowers.     

Changes and Trends in Environmental Education (1970–75)

The authors surveyed 15 secondary school teachers in 5 states about how they designed and implemented long-term stream monitoring in their classrooms and the problems and benefits they encountered. The authors surveyed students involved in the stream monitoring projects to obtain their perspective. Teachers reported that stream monitoring provided real-world application of concepts discussed during class and offered an interdisciplinary learning experience for students.     

The physical education predisposition scale: Preliminary tests of reliability and validity in Australian students

The main aim of this study was to psychometrically test the Physical Education Predisposition Scale (PEPS) with a cohort of Australian students, to assess secondary school students’ perceived PE ability and PE worth. Secondary aims were to explore how the two variables were related and to investigate age and gender differences. Altogether, 266 Year 7, 8, 9 and 10 students (aged 12–16 years), from four schools within the South Eastern region of Melbourne, completed the PEPS at both time points. Principal components analysis revealed the presence of a simple two-factor structure explaining 66.9% of the variance. Factor 1 (labelled perceived PE worth) reflected enjoyment and attitude (α = .91), and factor 2 (labelled perceived PE ability) represented perceptions of competence and self-efficacy (α = .92). Significant positive correlations were observed between the two factors (r = .50–.82, P < .001). Boys scored significantly higher than girls on perceived PE ability (P = .01), and year 7 students scored significantly higher compared to Year 9 students (P = .002). Our results support the potential of the PEPS as a concise measurement tool for use in the PE setting, for both teachers and researchers.     

Industrial Experience Projects: A Balance of Process and Product

Students in the final year of the Bachelor of Computing degree at Monash University must do a full year group project as a capstone subject. Each group of five or six builds a real system which is normally for a client outside the university. The project usually necessitates learning some skills that have not been taught in the course. Each group works on a different project. The emphasis is on management issues and the software development process as much as on the product, with a set of deliverables and deadlines throughout the year, and an assessment strategy reflecting this.     

The federal communications commission and the regulation of children's television

This paper takes a specific issue, the regulation of children's television, and shows how that issue might best be examined. The method of analysis used is the Krasnow‐Longley‐Terry systems approach to broadcast regulation.     

THE IMPACT OF A ‘CITIZEN AFFAIRS’ WORKSHOP ON ANOMIA,LIFE SATISFACTION AND INTERNAL‐EXTERNAL CONTROL IN A SELECTED GROUP OF OLDER ADULTS

An educational experience designed to increase knowledge of the political process, provide peer interaction, and promote civic involvement did appear to enhance internal locus of control in a selected sample of older adults. No significant changes in anomia or life satisfaction occurred. Implications of the findings for educational programming for older adults are discussed. It is suggested that the SRS model used in the study should be tested further for exploring the impact of educational programs upon internal‐external control.     

Contextually Based Professional Development

In this article, the authors detail a study of a three-year professional development project designed to increase in-service teachers’ classroom technology integration. Participants engaged in learning activities that modeled technology integration from a contextually based perspective that included technology, and pedagogical and content knowledge. Although participants reported having very limited technology skills before professional development began, after two years they reported a significant increase in using technology skills. In addition, participants reported increased comfort and confidence in using technology to the level where they changed their teaching practice to integrate technology. Indeed, between years two and three, participants reported a significant increase in technology use for learning by their students.
