ABSTRACT

Faculty and students evaluate the curriculum design and delivery of a synchronous online PhD program in social work that prepares scholar-practitioners in social work research, education, and organizational practice. The designers envision a collaborative community of scholars and leaders nurtured by a cohort-based, sequenced curriculum, and intentional faculty mentoring. This teaching and learning platform provides an opportunity to engage with a globally diverse population of doctoral students while fostering both relationships and quality learning outcomes. Educational design and pedagogical features of the program are described and analyzed through the collaborative thinking and learning platform of the Community of Inquiry (CoI) model’s interdependent elements–teaching, cognitive, and social presence. Eighteen students and ten faculty evaluated the strengths and limitations of the online program across each dimension of the model through student course evaluations, focus-group reflections, and qualitative faculty survey data. Student and faculty respondents specified the benefits of synchronous presence across all three dimensions. They also identified significant barriers, particularly in the areas of teaching and social presence. Implications and recommendations are based on a review of findings that inform pedagogical decisions and design options for online PhD education in social work.  相似文献

To attempt to understand Access to Higher Education provision as an educational social movement is to become caught up in a dialectial dilemma. Is Access allied to the older radical traditions of adult education through a collective emancipatory role or is its role to serve the educational needs of the individual student and/or the economic needs of society? Research carried out at the University of Exeter has shown that while there is a strong rhetoric within the Access movement that supports the more emancipatory approach, practitioners contradict this when questioned about the prime purpose of Access. Gramsci's theory of cultural hegemony can be used to address this contradiction by examining how sub‐cultures, such as the group of Access practitioners, create a mosaic of meaning or a reality map which is drawn from the conflicting ideologies which surround them.  相似文献

In recent years there has been an unprecedented increase in support staff in schools in England and Wales. There were widespread expectations that this will be of benefit to teachers and pupils but there has been little systematic research to address the impact of support staff. This study used a naturalistic longitudinal design to investigate the relationship between the amount of support (measured by teacher estimates and systematic observation) and pupils’ ‘Positive Approaches to Learning’ (PAL) and academic progress. There were over 8000 pupils across two cohorts and seven age groups. Results on PAL were not straightforward by there was a consistent trend for those with most support to make less academic progress than similar pupils with less support, and this was not explained by characteristics of the pupils such as piror attainment or level of special educational need.  相似文献

Child maltreatment among school children in the Kurdistan Province, Iran   总被引:3,自引:0,他引:3  
OBJECTIVE: This study examines the determinants of three types of child maltreatment: physical maltreatment, mental maltreatment, and child neglect among school children in the Kurdistan Province of Iran. The analysis examines the impact of socioeconomic, familial, demographic, and household dynamic factors on the three child maltreatment outcomes, and compares the differential impact of these factors across the three types of child maltreatment. A greater understanding of the factors associated with child maltreatment has the potential to inform public health interventions aimed at reducing specific forms of maltreatment and at identifying at risk populations. METHODS: Data were collected from 1,370 school students, age 11-18. Separate logistic models are fitted for six binary outcomes examining self-reported experiences of physical maltreatment in the home or school, mental maltreatment in the home or school, and child neglect in the home or school. RESULTS: Male children were more likely to report experiencing any kind of child maltreatment than girls. Residency in a rural area, poor parental relationships and the use of addictive substances by household members were associated with increased odds of reporting child maltreatment. Poor school performance was associated with the reporting of experiencing maltreatment at school. CONCLUSION: Each of the forms of child maltreatment is highly correlated with socioeconomic, demographic, and living condition factors. The results point to the strong influence that familial factors have in shaping a child's likelihood of reporting maltreatment. Characteristics of the mother were associated with maltreatment, but not characteristics of the father. The results highlight a number of mechanisms through which public health interventions may seek to reduce the prevalence of child maltreatment in Kurdistan; different approaches are needed to reduce child maltreatment in the home and school environments.  相似文献

The sweet spot of a cricket bat for low speed impacts   总被引:2,自引:1,他引:1  
The impact location of a cricket ball on a cricket bat has a large influence on the resulting rebound velocity of the ball. To measure this, a cricket bat was swung in a pendulum motion towards a cricket ball suspended in space. The position of the ball was modified so that it impacted the bat at 24 different positions on the face of the bat. This included six positions longitudinally and four positions laterally. The speed of the bat and each rebound were measured by a radar gun so that the apparent coefficient of restitution (ACOR) could be calculated. Impacts occurring centrally and 1?cm either side of the midline produced significantly higher rebound speeds and ACOR??s than impacts occurring 2 and 3cm off centre (p?<?0.01). Impacts occurring 15?C20?cm from the base of the bat produced the highest rebound speeds (p?<?0.01) and impacts occurring 20?C30?cm from the base of the bat produced the highest ACOR values. Implications for higher speed impacts and game scenarios are discussed.  相似文献

Energy system contribution to 1500- and 3000-metre track running   总被引:1,自引:0,他引:1  
The aim of the present study was to quantify the contributions of the aerobic and anaerobic energy systems to 1500- and 3000-m track running events during all-out time-trials performed individually on a synthetic athletic track. Ten 3000-m (8 males, 2 females) and fourteen 1500-m (10 males, 4 females) trained track athletes volunteered to participate in the study. The athletes performed a graded exercise test in the laboratory and two time-trials over 1500 or 3000 m. The contributions of the energy systems were calculated by measures of race oxygen uptake, accumulated oxygen deficit (AOD), race blood lactate concentration, estimated phosphocreatine degradation and some individual muscle metabolite data. The relative aerobic energy system contribution (based on AOD measures) for the 3000 m was 86% (male) and 94% (female), while for the 1500 m it was 77% (male) and 86% (female). Estimates of anaerobic energy expenditure based on blood lactate concentrations, while not significantly different (P > 0.05), were generally lower compared with the AOD measures. In conclusion, the results of the present study conform with some recent laboratory-based measures of energy system contributions to these events.  相似文献

Social informatics is the body of research that examines the design, uses, and consequences of information and communication technologies in ways that take into account their interaction with institutional and cultural contexts. This article serves as a brief introduction to social informatics. Examples such as computer networks, scientific communication via electronic journals, and public access to the Internet are used to illustrate key ideas from social informatics research. Some of the key themes include the importance of social contexts and work processes, sociotechnical networks, public access to information, and social infrastructure for computing support. The article draws upon 25 years of systematic analytical and critical research about information technology and social change.  相似文献
