Protecting the Great Barrier Reef: analysing the impact of a conservation documentary and post-viewing strategies on long-term conservation behaviour     

Karen Hofman  Karen Hughes 《Environmental Education Research》2018,24(4):521-536

Nature-based tourism experiences have the potential to change the environmental knowledge, attitudes and behavior of visitors; but such experiences may be beyond the physical and/or financial reach of many people. To influence the conservation behavior of populations world-wide, a more accessible yet equally effective strategy is required. Using an experimental design, this study explored whether a conservation documentary about Australian marine environments, together with post-viewing support materials, prompted the adoption of conservation behaviours. Questionnaires revealed environmental knowledge, attitudes and behavioural intentions rose immediately after viewing the documentary. Ten weeks later, these levels were maintained or decreased slightly for those who received post-viewing support (Facebook, help sheet or both), but decreased markedly in the control group. Results are similar to those reported in wildlife tourism studies. Implications for the use of documentaries in place of nature experiences are discussed.  相似文献

Middle School Teachers’ Use of Mathematics to Make Sense of Student Solutions to Proportional Reasoning Problems     

Erik Jacobson  Joanne Lobato  Chandra H. Orrill 《International Journal of Science and Mathematics Education》2018,16(8):1541-1559

Mathematics teacher education aims to improve teachers’ use of mathematical knowledge to support teaching and learning, an aspect of pedagogical content knowledge (PCK). In this study, we interviewed teachers to understand how they used mathematics to make sense of student solutions to proportional reasoning problems. The larger purpose was to find accurate ways of categorizing teachers’ ability to do this vital aspect of teaching and thereby to inform assessment, teacher education, and professional development. We conjectured that teachers’ PCK for proportional reasoning could be reliably described in terms of attention to quantitative meanings in story problem contexts and in terms of understanding naïve forms of proportional reasoning. Instead, our findings reveal that individual teachers used a variety of means to make sense of (1) cognitively similar student solutions to different tasks and (2) mathematically related steps of a student solution within a single task. These findings illustrate the complexity of PCK for the topic of proportional reasoning and suggest the limits of what can be inferred about teacher knowledge from teachers’ evaluations of student solutions. We discuss implications for teacher education and assessment.  相似文献   

Body composition of English Premier League soccer players: Influence of playing position,international status,and ethnicity     

Laura Sutton  Mark Scott  Joanne Wallace  Tom Reilly 《Journal of sports sciences》2013,31(10):1019-1026

Abstract

Body composition is a key consideration in the physical make-up of professional soccer players. The aims of the present study were to determine whether the body composition of professional soccer players varied according to playing position, international status or ethnicity, and to establish which variables best distinguished the soccer players from a reference group. Body composition was assessed using dual-energy X-ray absorptiometry in 64 male professional soccer players. Measured variables included bone mineral density and the relative amounts of lean and fat mass. Data were analysed using analysis of variance and stepwise discriminant function. The soccer players recorded better values than a reference group (n = 24) for all body composition compartments. Percent lean mass and bone mineral density were the variables best able to identify the soccer players (95.5% correctly classified). Differences in body composition were evident between goalkeepers and outfield players, but not between outfield playing positions. No differences were found on the basis of international status. The non-Caucasian players demonstrated significantly lower percent body fat (9.2 ± 2.0%) than the Caucasian players (10.7 ± 1.8%). It was concluded that body composition is important for elite soccer players, but that homogeneity between players at top professional clubs results in little variation between individuals.  相似文献   

Reliability and validity of field-based measures of leg stiffness and reactive strength index in youths     

Rhodri S. Lloyd  Jon L. Oliver  Michael G. Hughes  Craig A. Williams 《Journal of sports sciences》2013,31(14):1565-1573

Abstract

The aim of the study was to assess the reliability of a mobile contact mat in measuring a range of stretch–shortening cycle parameters in young adolescents. Additionally, vertical leg stiffness using contact mat data was validated against a criterion method using force–time data. The reliability study involved 18 youths completing a habituation and three separate test sessions, while 20 youths completed a single test session for the validity study. Participants completed three trials of a squat jump, countermovement jump, and maximal hopping test and a single trial of repeated sub-maximal hopping at 2.0 Hz and 2.5 Hz. All tests were performed on the contact mat. Reliability statistics included repeated-measures analysis of variance, intraclass correlation coefficient, and coefficient of variation (CV), while the correlation coefficient (r) and typical error of estimate (TEE) were reported for the validity study. Squat jump height was the most reliable measure (CV = 8.64%), while leg stiffness during sub-maximal hopping, and reactive strength index produced moderate reliability (CV = 10.17–13.93% and 13.98% respectively). Measures of leg stiffness obtained from contact mat data during sub-maximal hopping were in agreement with the criterion measure (r = 0.92–0.95; TEE = 6.5–7.5%), but not during maximal hopping (r = 0.59; TEE = 41.9%). The contact mat was deemed a valid tool for measuring stretch–shortening cycle ability in sub-maximal but not maximal hopping. Although reliability of performance was generally moderate, the tests offer a replicable assessment method for use with paediatric populations.  相似文献   

Effects of playing surface on physiological responses and performance variables in a controlled football simulation     

Michael G. Hughes  Laurence Birdsey  Rob Meyers  Daniel Newcombe  Jon Lee Oliver  Paul M. Smith 《Journal of sports sciences》2013,31(8):878-886

Abstract

In spite of the increased acceptance of artificial turf in football, few studies have investigated if matches are altered by the type of surface used and no research has compared physiological responses to football activity on artificial and natural surfaces. In the present study, participants performed a football match simulation on high-quality artificial and natural surfaces. Neither mean heart rate (171 ± 9 beats · min^?1 vs. 171 ± 9 beats · min^?1; P > 0.05) nor blood lactate (4.8 ± 1.6 mM vs. 5.3 ± 1.8 mM; P > 0.05) differed between the artificial and natural surface, respectively. Measures of sprint, jumping and agility performance declined through the match simulation but surface type did not affect the decrease in performance. For example, the fatigue index of repeated sprints did not differ (P > 0.05) between the artificial, (6.9 ± 2.1%) and natural surface (7.4 ± 2.4%). The ability to turn after sprinting was affected by surface type but this difference was dependent on the type of turn. Although there were small differences in the ability to perform certain movements between artificial and natural surfaces, the results suggest that fatigue and physiological responses to football activity do not differ markedly between surface-type using the high-quality pitches of the present study.  相似文献

Health-inclusive higher education: listening to students with disabilities or chronic illnesses     

Kate Hughes  Tim Corcoran  Roger Slee 《高等教育研究与发展》2016,35(3):488-501

This paper reports on a small-scale project undertaken with tertiary students who identified as having an impairment either at enrolment or by registering with the university's Disability Support Unit (DSU). The aim of the study was to explore with these students ways in which the university was currently meeting their academic support needs and the ways in which these needs might be better met. Consistent with the definition of disability within the Australian Disability Discrimination Act, it became apparent that a significant number of students who identified with that definition, or sought help from disability services, also presented with needs arising from chronic illness. The majority of participants cited an emotional or psychological illness, rather than a physical, intellectual or sensory one, as a possible precursor to difficulties in engagement with the university. We conclude by considering whether commonly used institutional categories are apposite to an understanding of the ways in which students perceive themselves and, importantly, their engagement with the university and success within it.  相似文献   

Irish student teachers’ levels of moral reasoning: context,comparisons, and contributing influences     

Joanne O’Flaherty  Jim Gleeson 《Teachers and Teaching》2017,23(1):59-77

The moral role of the teacher has long been recognised and this has implications for the selection and education of student teachers. There is growing recognition of the importance of teachers’ capacity to make sound moral judgements and of the influence of teachers’ levels of moral reasoning on their professional practice. The paper presents the findings of a longitudinal study of 102 undergraduate student teachers who completed the DIT 2 measure of moral reasoning, at the beginning, mid-point and end of their four-year degree programme at an Irish university. While these students’ levels of moral reasoning were found to be higher than those of their international peers, more than half of graduating students were reasoning at the conventional level as defined by Kohlberg. These findings are located in the context of Irish education policy and practice. Some possible explanations for the students’ performance are suggested and discussed including their entry characteristics, the status of the teaching profession in Ireland, the nature of their teacher education programme and participation in the Transition Year option.  相似文献   

General education in research universities: Training programs for teaching assistants     

Julie A. Hughes 《Innovative Higher Education》1991,16(1):79-89

Suggestions for general education reforms have advocated smaller classes and greater participation by senior faculty. This is not feasible given the reward structure and extensive use of teaching assistants at research universities. Realistic reform efforts must account for the reward structure and focus on training programs for teaching assistants.She obtained her Ph.D. (1987) in Higher Education Administration, and her M.S. (1982) in Counseling and Human Development, both from the University of Iowa.  相似文献
