Rules, roles and tools: Activity theory and the comparative study of e-learning     

Angela Benson  Cormac Lawler  Andrew Whitworth 《British journal of educational technology : journal of the Council for Educational Technology》2008,39(3):456-467

Activity theory (AT) is a powerful tool for investigating 'artefacts in use', ie, the ways technologies interrelate with their local context. AT reveals the interfaces between e-learning at the macro- (strategy, policy, 'campus-wide' solutions) and the micro-organisational levels (everyday working practice, iterative change, individual adaptation). In AT, contexts are conceived of as activity systems in which human, technological and organisational elements are interrelated and largely inseparable. Both the subjects of the activity system (internal) and the wider community (external) mediate their activities through tools, rules and roles. This paper shows how a course management system (CMS) exerts an influence over all three of these mediators, though the exact nature of this influence depends on the particular configuration of each activity system. This is illustrated with reference to two case study programmes, both of which used Moodle as their CMS, but which had activity systems structured in quite different ways; the programmes also had different relationships with their external organisational environment.  相似文献   

Further abuse of sexually abused children     

Swanston HY  Parkinson PN  Oates RK  O'Toole BI  Plunkett AM  Shrimpton S 《Child abuse & neglect》2002,26(2):115-127

OBJECTIVE: To determine the incidence of re-abuse in children known to have been sexually abused and to find factors that increase the risk of re-abuse. METHOD: The study group consisted of 183 children with substantiated sexual abuse who presented to two children's hospitals' Child Protection Units in Sydney, Australia during 1988 through 1990. At intake, when the children were aged between 5 years and 15 years, data about the child, the family, and the nature of the index sexual abuse were collected. Six years after presentation for the abuse, records of the Department of Community Services were checked to see if any of the young people had been the subject of substantiated notifications for abuse/neglect before and after intake to the study. Predictors of notifications for abuse/neglect after presentation for the index sexual abuse were identified. RESULTS: Of the sexually abused young people, nearly one in three were the subject of subsequent substantiated notifications to the Department of Community Services for some form of child abuse and neglect or behavior which placed them at risk of harm. Later notifications for abuse/neglect were predicted by notifications for emotional abuse before the index sexual abuse (adjusted RR = 4.88, CI: 1.43 to 16.65), severity of the index sexual abuse (p = .03), and the number of changes in the child's primary caregivers before intake (p = .03). Approximately one in six of the sexually abused young people were notified for sexual abuse after intake to the study. One in 10 also had prior notifications for sexual abuse. Sexual abuse notifications after study intake were predicted by caregiver changes before intake (p = .01) and whether or not there were notifications for emotional abuse before the index sexual abuse (adjusted RR = 3.40, CI: 1.05 to 11.02). CONCLUSIONS: Revictimization of children appears to be a marker of ongoing family dysfunction. Intervention in child sexual abuse needs to consider a range of risk factors associated with re-abuse and, in particular, should focus on family functioning if further abuse is to be prevented.  相似文献   

Developing educational goals: insights from a Peer Assisted Teaching Scheme     

Bella Ross  Angela Carbone  Katherine Lindsay  Steve Drew  Liam Phelan  Caroline Cottman 《International Journal for Academic Development》2016,21(4):350-363

The rapid changes facing higher education are placing increased focus on the quality of the student experience, achieving learning outcomes, and employability expectations. As a result, academics in teaching roles are increasingly measured on performance via student evaluations amplifying attention on professional development initiatives for academics. One such initiative is the Peer Assisted Teaching Scheme currently in practice across many Australian universities. The critical component of the scheme is the establishment of teaching goals that provide focus and direction for the peer partnership. This study addresses two questions: (1) Around which aspects do academics set their goals for teaching improvement? and (2) How do academics’ goals align with the SMART goal-setting framework that is prescribed in the scheme? Findings from five Australian universities showed that goals align with a variety of educational areas yet many were underdeveloped, or misaligned with the proposed strategy. The implications of this are discussed and a framework for setting education goals for teaching improvement is developed.  相似文献   

Promoting a Culture of Thinking in the Young Child     

Angela K. Salmon 《Early Childhood Education Journal》2008,35(5):457-461

Conscious of the interplay between nature and nurture in determining a child’s individuality and success in life, the author embarked a group of teachers in an action research project towards nurturing a culture of thinking in young children. Considering the positive effects of routines in early learning experiences, the research consisted in implementing thinking routines to engage young children’s minds in thinking activities. The study took place in two Reggio-inspired schools where participating teachers documented children’s work as part of their teaching. The documentation was a key element to make children’s thinking visible as they installed the culture and language of thinking in their classrooms. The study found that thinking routines build up positive attitudes about thinking and learning. By re-visiting their documented work children developed metacognitive and critical thinking skills which make them more alert to situations that call for thinking.  相似文献   

Dispositions Toward Families and Family Involvement: Supporting Preservice Teacher Development   总被引：1，自引：0，他引：1  

Angela C. Baum  Kevin J. Swick 《Early Childhood Education Journal》2008,35(6):579-584

This article highlights the importance of nurturing preservice teachers as they develop the dispositions essential to establish empowering relationships with children’s families. The authors identify and describe several key dispositions necessary for working with families and offer suggestions for ways that these elements might be integrated into early childhood teacher preparation programs.  相似文献   

Higher Education and Emerging Technologies: Shifting Trends in Student Usage     

Erin Dorris Cassidy  Angela Colmenares  Glenda Jones  Tyler Manolovitz  Lisa Shen  Scott Vieira 《The Journal of Academic Librarianship》2014

This study serves as an update to a previous study by Sam Houston State University librarians about the use and preferences of Internet, communication, and educational technologies among students. Since the previous study was initiated in 2010, the iPad has made its debut and significantly altered the educational technology landscape. In this new landscape, this study investigates student usage of such technologies as instant messaging, cell phones, e-readers, social networking, RSS feeds, podcasts, and tablets. In addition, this study aims to determine which technologies students prefer the library to utilize for a variety of services, such as reference assistance or book renewals, and which technologies may not be worth the investment, such as geosocial networking. The information gained from this survey is intended to provide guidance for libraries looking to provide services utilizing the most popular technologies with the most efficient use of resources. Survey results show an increasing use and dependence on educational technologies and a desire for basic library services to be available on a variety of platforms and technologies.  相似文献   

Social Media and Speed-Driven Journalism: Expectations and Practices     

Angela M. Lee 《媒体管理杂志》2015,17(4):217-239

To examine how journalists use, and are affected by, social media in their pursuit for speed, this study conducted in-depth interviews with 11 journalists from various U.S. national, metropolitan, and local newspapers. Findings revealed an industry-wide expectation that journalists engage with audiences on social media. But in terms of practice, most interviewees reported that they mainly use Twitter to facilitate news work (i.e., contact hard-to-reach sources) and communicate with other journalists; audiences are rarely their focus on social media. The interviewees were also asked about their perception of how Twitter affects audiences. Most interviewees were unsure of its impact on credibility, but believed that it may promote news use, although not contribute to news organizations’ bottom line. This study offers five reasons why social media are not saving the newspaper industry, and discusses managerial implications regarding the gap between social media expectations and practices.  相似文献

Effects of an 8-weeks erythropoietin treatment on mitochondrial and whole body fat oxidation capacity during exercise in healthy males     

Amelia Guadalupe-Grau  Ulla Plenge  Signe Helbo  Marianne Kristensen  Peter Riis Andersen  Angela Fago 《Journal of sports sciences》2015,33(6):570-578

The present investigation was performed to elucidate if the non-erythropoietic ergogenic effect of a recombinant erythropoietin treatment results in an impact on skeletal muscle mitochondrial and whole body fatty acid oxidation capacity during exercise, myoglobin concentration and angiogenesis. Recombinant erythropoietin was administered by subcutaneous injections (5000 IU) in six healthy male volunteers (aged 21 ± 2 years; fat mass 18.5 ± 2.3%) over 8 weeks. The participants performed two graded cycle ergometer exercise tests before and after the intervention where VO_2max and maximal fat oxidation were measured. Biopsies of the vastus lateralis muscle were obtained before and after the intervention. Recombinant erythropoietin treatment increased mitochondrial O₂ flux during ADP stimulated state 3 respiration in the presence of complex I and II substrates (malate, glutamate, pyruvate, succinate) with additional electron input from β-oxidation (octanoylcarnitine) (from 60 ± 13 to 87 ± 24 pmol · s^?1 · mg^?1 P < 0.01). β-hydroxy-acyl-CoA-dehydrogenase activity was higher after treatment (P < 0.05), whereas citrate synthase activity also tended to increase (P = 0.06). Total myoglobin increased by 16.5% (P < 0.05). Capillaries per muscle area tended to increase (P = 0.07), whereas capillaries per fibre as well as the total expression of vascular endothelial growth factor remained unchanged. Whole body maximal fat oxidation was not increased after treatment. Eight weeks of recombinant erythropoietin treatment increases mitochondrial fatty acid oxidation capacity and myoglobin concentration without any effect on whole body maximal fat oxidation.  相似文献
