Relationships between exercise regulations and motivational consequences in university students     

Wilson PM  Rodgers WM  Fraser SN  Murray TC 《Research quarterly for exercise and sport》2004,75(1):81-91

The aim of this study was to examine propositions stemming from Self-Determination Theory (SDT) that contend motivational consequences vary as a function of different regulations in the exercise domain. Participants (N = 276; n = 98 men; n = 178 women) completed inventories assessing exercise regulations, current exercise behavior, and behavioral intentions to continue exercising for the next 4 months and the effort and importance associated with exercise participation. Bivariate analyses indicated autonomous exercise regulations (identified and intrinsic) were the strongest correlates of each motivational consequence across both sexes, and introjected regulation was positively associated with exercise consequences in women. Simultaneous multiple regression analyses indicated that exercise regulations accounted for a sizeable portion of the variance across each motivational consequence in both sexes (R2adj values ranged from .20 to .53). Both regression and structure coefficients revealed that introjected regulation was a stronger motivational force in women than men, and identified regulation was the most important predictor of all three motivational consequences in both sexes. Collectively, these findings suggest that exercise regulations differentially predict motivational consequences across sexes, and future research using this theoretical framework for examining motivational issues pertinent to the exercise domain appears warranted.  相似文献   

The Future of Zoos: A New Model for Cultural Institutions     

John Fraser  Dan Wharton 《Curator: The Museum Journal》2007,50(1):41-54

Abstract Over the last 30 years, the international zoo movement has gradually adopted conservation as its mantra. World‐class zoos have invested substantially in species conservation and animal research as part of their involvement in wildlife conservation. However, zoo exhibit interpretation, policy development, and strategic planning are yet to be organized around a well‐developed agenda with a clear set of conservation objectives. As museums increasingly redefine their role in society to speak about alternative futures for living with nature, zoos have the potential to become much more focused cultural change agents, potentially crafting a new vision for how society can live in a productive relationship with the world's remaining biodiversity. This article argues for an activist approach in which institutions with living collections would take on unique conservation tasks including scientifically grounded promotion of conservation values.  相似文献   

Considering student retention as a complex system: a possible way forward for enhancing student retention     

Jonas Forsman  Maartje van den Bogaard  Cedric Linder  Duncan Fraser 《European Journal of Engineering Education》2015,40(3):235-255

This study uses multilayer minimum spanning tree analysis to develop a model for student retention from a complex system perspective, using data obtained from first-year engineering students at a large well-regarded institution in the European Union. The results show that the elements of the system of student retention are related to one another through a network of links and that some of these links were found to be strongly persistent across different scales (group sizes). The links were also seen to group together in different clusters of strongly related elements. Links between elements across a wide range of these clusters would have system-wide influence. It was found that there were no elements that are both persistent and have system-wide effects. This complex system view of student retention explains why actions to enhance student retention aimed at single elements in the system have had such limited impact. This study therefore points to the need for a more system-wide approach to enhancing student retention.  相似文献   

Effects of sodium phosphate and caffeine loading on repeated-sprint ability     

Christopher Buck  Kym Guelfi  Brian Dawson  Lars McNaughton  Karen Wallman 《Journal of sports sciences》2015,33(19):1971-1979

The effects of sodium phosphate and caffeine supplementation were assessed on repeated-sprint ability. Using a randomised, double-blind, Latin-square design, 12 female, team-sport players participated in four trials: (1) sodium phosphate and caffeine, (2) sodium phosphate and placebo (for caffeine), (3) caffeine and placebo (for sodium phosphate) and (4) placebo (for sodium phosphate and caffeine), with ~21 days separating each trial. After each trial, participants performed a simulated team-game circuit (4 × 15 min quarters) with 6 × 20-m repeated-sprints performed once before (Set 1), at half-time (Set 2), and after end (Set 3). Total sprint times were faster after sodium phosphate and caffeine supplementation compared with placebo (Set 1: P = 0.003; Set 2: d = ?0.51; Set 3: P < 0.001; overall: P = 0.020), caffeine (Set 3: P = 0.004; overall: P = 0.033) and sodium phosphate (Set 3: d = ?0.67). Furthermore, total sprint times were faster after sodium phosphate supplementation compared with placebo (Set 1: d = ?0.52; Set 3: d = ?0.58). Best sprint results were faster after sodium phosphate and caffeine supplementation compared with placebo (Set 3: P = 0.007, d = ?0.90) and caffeine (Set 3: P = 0.024, d = ?0.73). Best sprint times were also faster after sodium phosphate supplementation compared with placebo (d = ?0.54 to ?0.61 for all sets). Sodium phosphate and combined sodium phosphate and caffeine loading improved repeated-sprint ability.  相似文献

An Online Questionnaire for Evaluating Students' and Teachers' Perceptions of Constructivist Multimedia Learning Environments     

Dorit Maor  Barry J. Fraser 《Research in Science Education》2005,35(2-3):221-244

The purpose of this article is to describe the development, validation and use of the Constructivist Multimedia Learning Environment Survey (CMLES). This questionnaire assesses teachers' and students' perceptions of the learning environment when students use online multimedia programs while teachers use constructivism as a referent for their teaching. The design of the questionnaire was based on a constructivist approach to learning and focused on the process of learning with the multimedia program and on the nature of that program. Before the use of the CMLES becomes widespread, it was important to determine whether it is valid and reliable. Therefore, a study involving 221 students in 12 high school classrooms into statistical validation and interpretive validation of the questionnaire was undertaken. For this sample of Grade 10 and 11 students who completed the actual and preferred forms of the questionnaire, the CMLES scales demonstrated a high degree of internal consistency reliability (with alpha reliability coefficients ranging from .73 to .82), as well as satisfactory factorial validity and discriminant validity. Therefore, the study supports the reliability and validity of the CMLES for assessing students' and teachers' perceptions of one important aspect in evaluating learning environments which promote the use of multimedia programs and constructivist learning approaches.  相似文献   

Associations between school-level environment and science classroom environment in secondary schools     

Dr Jeffrey P. Dorman  Barry J. Fraser  Campbell J. McRobbie 《Research in Science Education》1995,25(3):333-351

This article describes a study of links between school environment and science classroom environment. Instruments to assess seven dimensions of school environment (viz., Empowerment, Student Support, Affiliation, Professional Interest, Mission Consensus, Resource Adequacy and Work Pressure) and seven dimensions of classroom environment (viz., Student Affiliation, Interactions, Cooperation, Task Orientation, Order & Organisation, Individualisati n and Teacher Control) in secondary school science classrooms were developed and validated. The study involved a sample of 1,318 students in 64 year 9 and year 12 science classes and 128 teachers of science in Australian secondary schools. Using the class mean as the unit of analysis for student data, associations between school and classroom environment were investigated using simple, multiple and canonical correlational analyses. In general, results indicated weak relationships between school and classroom environments and they reinforced the view that characteristics of the school environment are not transmitted automatically into science classrooms.  相似文献
