Small significant networks as birds of a feather     

Gary Poole  Isabeau Iqbal 《International Journal for Academic Development》2019,24(1):61-72

Current research indicates that instructors find support for their teaching via membership in small social networks. The present study was conducted to further our understanding of these networks by looking specifically at the perceptions network members hold of each other in terms of similarity of beliefs and the value of their interactions. Results indicate that participants were more likely to perceive high rather than low similarity of beliefs with others in their network, and value was positively associated with perceived similarity. Implications for teaching practice and the work of educational developers are discussed.  相似文献   

Do we have any theories of group communication?     

Marshall Scott Poole 《Communication Studies》2013,64(3):237-247

The essay presents criteria for a “good theory” and then reviews advances in small group communication research during the 1980s. The fact that comparatively few scholars are dedicated to such research is then related to the criteria for good theory in discussions of, first, metaphors and imagination; second, puzzles and problems; and third, real‐world significance and outcomes. A call is made for the kind of research that will result in better small group theory.  相似文献   

Sweat lactate response during cycling at 30°C and 18°C WBGT     

JM Green  RC Pritchett  DC Tucker  TR Crews  JR McLester 《Journal of sports sciences》2013,31(4):321-327

Sweat lactate reflects eccrine gland metabolism. However, the metabolic tendencies of eccrine glands in a hot versus thermoneutral environment are not well understood. Sixteen male volunteers completed a maximal cycling trial and two 60-min cycling trials [30°C?=?30±1°C and 18°C?=?18±1°C wet bulb globe temperature (WBGT)]. The participants were requested to maintain a cadence of 60 rev?·?min^?1 with the intensity individualized at ～ 90% of the ventilatory threshold. Sweat samples at 10, 20, 30, 40, 50 and 60?min were analysed for lactate concentration. Sweat rate at 30°C (1380±325?ml?·?h^?1) was significantly greater (P<0.05) than at 18°C (632±311?ml?·?h^?1). Sweat lactate concentration was significantly greater (P<0.05) at each time point during the 18°C trial, with values between trials tending to converge across time. During the 30°C trial, both heart rate (20, 30, 40, 50 and 60?min) and rectal temperature (30, 40, 50 and 60?min) were significantly higher than in the 18°C trial. Higher sweat lactate concentrations coupled with lower sweat rates may indicate a greater relative contribution of oxygen-independent metabolism within eccrine glands during exercise at 18°C. Decreases in sweat lactate concentration across time suggest either greater dilution due to greater sweat volume or increased reliance on aerobic metabolism within eccrine glands. The convergence of lactate concentrations between trials may indicate that time-dependent modifications in sweat gland metabolism occur at different rates contingent partially on environmental conditions.  相似文献

Promoting Online Collaborative Learning Experiences for Teenagers     

Minjuan Wang  Melissa Poole  Bruce Harris  Paul Wangemann 《Educational Media International》2013,50(4):203-215

This paper describes a project that engages teenagers in using Internet-based tools to collaborate in problem-based learning. Motorola Expeditions is designed to help young people develop skills in using new network technologies to work together in teams to solve real world problems. In Expeditions 2000, 27 teenagers worked in teams with six on-site and four online mentors to develop a marketing plan for one or more personal communication sector technologies, such as cell phones, specifically targeting teenage consumers. Participants were surveyed before and after the project about their attitudes towards collaborative learning, their confidence in collaborating online and their competence in using certain online tools. Data were also gathered through observation of online communication, weekly feedback surveys and interviews with mentors. Results show a significant increase in the participants' self-confidence in collaborating online and in their competence in using online communication tools to collaboratively solve problems. La promotion d’expériences éducatives en ligne en en collaboration pour des adolescents. Cet article décrit un projet que engage des adolescents à utiliser des outils basés sur internet pour collaborer dans l'enseignement fondé sur la résolution de problèmes. Les expéditions Motorola sont concues pour aider les jeunes à développer des compétences pour utiliser les nouvelles technologies du réseau et travailler en équipes pour résoudre les problèmes réels du monde. Dans les Expéditions 2000, 27 adolescents ont travaillé en équipes avec 6 tuteurs sur le site et quatre en ligne pour élaborer un plan de marketing pour une en plusieurs technologies de communication personnelles telles que les téléphones portables visant spécialement des consommateurs adolescents. On a sondé les participants avant et après le projet sur leurs attitudes à l'égard de l'enseignement en collaboration de leur confiance dans la collaboration en ligne et de leur compétence dans l'utilisation de certains outils en ligne. On a aussi recueilli des données grâce à l'observation de la communication en ligne, grâce à des contrats de feedback hebdomadaires et de entretiens avec les tuteurs. Les résultats montrent une augmentation significative de la confiance in soi des participants à la collaboration en ligne et de leur compétence dans l'utilisation des outils de communication en ligne pour résoudre les problèmes en collaboration. Förderung von online collaborativen Lernerfahrungen für Jugendliche. Die Abhandlung beschreibt ein Projekt, in dem Jugendliche mit Hilfe von Internet Werkzeugen Lernprobleme gemeinsam lösen. Motorola Expeditions wurde konzipiert, um jungen Menschen zu helfen, Fertigkeiten in der Anwendung neuer Netzwerktechnologien zu entwickeln und als Team zusammen zu arbeiten um reale Probleme zu lösen. In Expeditons 2000 arbeiteten 27 Jugendliche in Teams mit 6 “onsite"- und 4 online-Lehrkräften, um einen Marketingplan für einen oder mehr Sektoren betreffende individuelle Kommunikationstechnologien zu entwickeln, wie z.B. mobile Telefone, die sich insbesondere an jugendliche Verbraucher wenden. Die Teilnehmer wurden vorher und nach dem Projekt zu ihrer Einstellung zum collaborativen Lernen befragt, ihrem Zutrauen in das gemeinsame online-Arbeiten und zu ihrer Kompetenz hinsichtlich der Anwendung gewisser online Werkzeuge. Die Daten wurden auch durch Observation von online-Kommunikation, wöchentlichen Auswertungen und Interviews mit den Lehrkräften gesammelt. Die Resultate zeigen eine deutliche Steigerung des Selbstvertrauens der Teilnehmer online zusammenzuarbeiten, sowie ihrer Fähigkeit, online- Kommunikationswerkzeuge zu nutzen, um gemeinsam Probleme zu lösen.  相似文献   

A comparison of traditional and modified Summated-Heart-Rate-Zones models to measure internal training load in basketball players     

Aaron T. Scanlan  Jordan L. Fox  Jacqueline L. Poole  Daniele Conte  Zoran Milanović  Michele Lastella 《Measurement in physical education and exercise science》2018,22(4):303-309

The Summated-Heart-Rate-Zones training load (SHRZ TL) model is used to measure internal loading; however, a major limitation of this approach is the use of broad heart rate (HR) zones to quantify exercise intensity. Therefore, this study aimed to compare SHRZ TL outcomes derived using the traditional model and modified approaches using smaller HR zones. HR responses were monitored in 15 semi-professional basketball players during preparatory training to calculate SHRZ TL using the traditional approach with 10%HR_max zones (SHRZ₁₀) and modified approaches with 5%HR_max zones (SHRZ₅) and 2.5%HR_max zones (SHRZ_2.5). Significant (P < 0.001) differences were evident in SHRZ TL between SHRZ₁₀ (254.2 ± 41.7 AU) and SHRZ₅ (275.9 ± 43.3 AU, unclear, small) as well as SHRZ_2.5 (286.7 ± 44.3 AU, very likely, moderate). Use of SHRZ_2.5 provides novel insight regarding internal loading in basketball players and may carry greater sensitivity for detection of maladaptive and adaptive responses to training.  相似文献   

In search of “the vibe”: Creating effective international education partnerships   总被引：2，自引：0，他引：2  

Troy?HeffernanEmail author  David?Poole 《Higher Education》2005,50(2):223-245

In common with universities in the United Kingdom, Canada and NewZealand, increasing numbers of Australian universities have established offshore education partnerships, particularly in the Asia-Pacific region. More than one-third of international students currently enrolled in Australian university courses study at a campus in their home country or somewhere other than in Australia (IDP 2002). Suchpartnerships, also assumed under the rubric of ‘transnational education’ and ‘franchising’, add additional challenges, complexities and risks to the roles of international education managers and administrators. Using convergent interviews and case studies, this paper identifies and examines the critical success factors for the successful establishment and development of relationships between Australian universities and their international partners. Critical among these are the development of effective communication structures and frameworks, the building of mutual trust, and the encouragement and demonstration of commitment between relationship partners.  相似文献   

Introducing micro-computers to micro-learners through play     

Theresa M. Rubens  Jennifer Poole  James L. Hoot 《Early Childhood Education Journal》1984,11(3):29-31

Computers, once available exclusively to wealthy industries, are now rapidly becoming as familiar in preschool and kindergarten classrooms as block and crayons. Articles making claims such as Learning by Computers at Age 4 and Computers Preparing Preschoolers for Kindergarten now permeate the news media. Increasing numbers of child care centers, attempting to maximize public interest in computers, now readily advertise Computer Tutor in their literature. Computer Tutor is often even listed above other important qualifications such as certified teachers and professional affiliations of centers.Theresa Rubens has had extensive experience working with children in both family day homes and child care centers. Jennifer Poole is the Nursery Director at the First United Methodist Church in Carrollton, TX. James L. Hoot is Assistant Professor of Early Childhood Education at North Texas State University in Denton, Texas.  相似文献
