This study examines two experienced teachers’ transformations and sense of agency as they implemented a writer’s workshop curriculum with multi-lingual third grade students. Multiple lines of inquiry guide the study including communities of practice (Lave & Wenger, 1991), teacher identities in figured worlds (Holland, Lachicotte, Skinner, & Cain, 1998), and the ethic of care (Noddings, 1984/2003). A constant comparative method was used to analyze classroom observation notes, interviews and debriefing sessions (Glaser & Strauss, 1967). Findings indicate that teachers transformed their pedagogical practices around writing, and at the same time reconsidered what it may mean to become renewed professionals.  相似文献   

Using compositional data analysis to explore accumulation of sedentary behavior,physical activity and youth health

Purpose:The study aimed to describe youth time-use compositions,focusing on time spent in shorter and longer bouts of sedentary behavior and physical activity(PA),and to examine associations of these time-use compositions with cardiometabolic biomarkers.Methods:Accelerometer and cardiometabolic biomarker data from 2 Australian studies involving youths 7-13 years old were pooled(complete cases with accelerometry and adiposity marker data,n=782).A 9-component time-use composition was formed using compositional data analysis:time in shorter and longer bouts of sedentary behavior;time in shorter and longer bouts of light-,moderate-,or vigorous-intensity PA;and"other time"(i.e.,non-wear/sleep).Shorter and longer bouts of sedentary time were defined as<5 min and>5 min,respectively.Shorter bouts of light-,moderate-,and vigorous-intensity PA were defined as<1 min;longer bouts were defined as≥1 min.Regression models examined associations between overall time-use composition and cardiometabolic biomarkers.Then,associations were derived between ratios of longer activity patterns relative to shorter activity patterns,and of each intensity level relative to the other intensity levels and"other time",and cardiometabolic biomarkers.Results:Confounder-adjusted models showed that the overall time-use composition was associated with adiposity,blood pressure,lipids,and the summary score.Specifically,more time in longer bouts of light-intensity PA relative to shorter bouts of light-intensity PA was significantly associated with greater body mass index z-score(zBMI)(β=1.79;SE=0.68)and waist circumference(β=18.35,SE=4.78).When each activity intensity was considered relative to all higher intensities and"other time",more time in light-and vigorous-intensity PA,and less time in sedentary behavior and moderate-intensity PA,were associated with lower waist circumference.Conclusion:Accumulating PA,particularly light-intensity PA,in frequent short bursts may be more beneficial for limiting adiposity compared to accumulating the same amount of PA at these intensities in longer bouts.  相似文献   

Investigating the role of a Web-based tool to promote collective knowledge in medical communities     

Federico?CabitzaEmail author  Carla?Simone 《知识管理研究与实践》2012,10(4):392-404

The paper reports a case study where a relatively lightweight technology in the form of a Web-based questionnaire was used to support members of a real community of professionals in externalizing and sharing their good practices and achieving a better awareness of and agreement on topics of common interest. We focused on an important medical association that counts more 1000 doctors all around the world as its members. In particular, we report how this association used the occasion of the on-line survey enabled by our technology to increase the awareness of its members about the actual heterogeneity of preferences existing in their daily clinical practice, and to trigger discussion toward a better consensus on best practices, appropriate indications, and treatments of choice for their profession and practice. We also report the result of a post-hoc evaluation of the Web-based technology employed, and draw some implications for the better design of this kind of tool in order to collect and share collective knowledge in specific professional domains.  相似文献   

EFLM Position Statement: Our profession now has a European name: Specialist in Laboratory Medicine     

Simone Zerah  Janet McMurray  Andrea Rita Horvath 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2012,22(3):272-273

We need a common name to have a clear identity which best describes the scope of the work we carry out for the patients.A clear and easily understood name which reflects the level of education and training of a specialist in the medical laboratory, and hence eligibility to be on the EC4 Register, is therefore needed, whatever academic background and whether polyvalent or sub-specialised.  相似文献   

Soziale Integration durch Sport?     

Simone Becker  Armando Häring 《Sportwissenschaft》2012,42(4):261-270

In this study the relationship between physical activity and different dimensions of social integration (number of friends, frequency of contact to friends, number of social contexts the individual is taking part in) is analysed using the data of the Partnermarktsurvey 2009. The concept of opportunities for interaction in foci of activity (here physical activity) is used as the theoretical framework. It can be shown that physical activity has an effect on the social integration of individuals: People who engage in physical activity have more friends, meet them more often and are integrated in more social contexts than people who are not physically active. Differences in social integration even exist among physically active people depending on the kind of sport activity and its form of organisation. Further the setting of the sport activity seems to be of importance. Finally it is recommended that longitudinal data used to investigate the exact causal effect of physical activity on social integration.  相似文献

Age of entry,sex, and academic achievement in elementary school children     

John D. Sweetland  Philip A. De Simone 《Psychology in the schools》1987,24(4):406-412

It was hypothesized that children who enter school at a relatively early age do less well on standard measures of school achievement than do their older peers. One hundred fifty-two children born in 1970 and attending grades one through six in an upper-middle-class, suburban school district were studied. In general, it was found that children born in the later quarters of the year did, in fact, perform less well than children in the same grade born earlier through grades one to four. Analyses of covariance yielded a main effect for birth quartile (p < .05) in most cases. A significant main effect for sex was found for language scores at grades two and three. Implications of these findings for age of school entry, educational programming, and screening procedures are discussed.  相似文献   

A paradox of sport management and physical activity interventions     

Karla A. Henderson 《Sport Management Review》2009,12(2):57-65

Managers of sports programs, facilities, and organizations can have a role in promoting health through physical activity participation. From the perspective of a leisure scientist who has examined various dimensions of leisure-time physical activity, this paper aims to appraise the status of how sports as potential physical activity interventions have been examined, particularly in the sport management literature. Although the purpose of many sport management organizations is to encourage spectatorship, sports have always offered significant opportunities for children and adults to be more physically active. Sports are a motivator for physical activity because they are enjoyable to participants. Therefore, research done by academics in sports management could reflect more about how mass participation recreational sports can serve as interventions to promote healthy physical activity behavior for individuals and within communities.  相似文献   

Round or rectangular tables for collaborative problem solving? A multimodal learning analytics study     

Milica Vujovic  Davinia Hernández-Leo  Simone Tassani  Daniel Spikol 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(5):1597-1614

The current knowledge of the effects of the physical environment on learners’ behaviour in collaborative problem-solving tasks is underexplored. This paper aims to critically examine the potential of multimodal learning analytics, using new data sets, in studying how the shapes of shared tables affect the learners’ behaviour when collaborating in terms of patterns of participation and indicators related to physical social interactions. The research presented in this paper investigates this question considering the potential interplay with contextual aspects (level of education) and learning design decisions (group size). Three dependent variables (distance between students, range of movement and level of participation) are tested using quantitative and qualitative analyses of data collected using a motion capture system and video recordings. Results show that the use of round tables (vs rectangular tables) leads to higher levels of on-task participation in the case of elementary school students. For university students, different table shapes seem to have a limited impact on their levels of participation in collaborative problem solving. The analysis shows significant differences regarding the relationship between group size and the distance between students, but there is no substantial evidence that group size affects the level of participation. The findings support previous research highlighting the importance of studying the role of the physical environment as an element of learning design and the potential of multimodal learning analytics in approaching these studies.  相似文献   

Putting the “I” back in team     

Simone L. Yearwood 《Journal Of Access Services》2017,14(3):146-152

In the summer of 2013, staff in the Access Services unit of an academic library began a cross-training and collaboration project in an effort to provide continued library service to the campus community. The cross-training was established in an attempt to address a shortage of staff as a result of budget cuts. The cross-training resulted in the transitioning of the Access Services units and the creation of a collaborative team. The development of cross-training and its benefits are addressed in addition to lessons learned.  相似文献
