A common phenomenon in online discussion groups is the individual who baits and provokes other group members, often with the result of drawing them into fruitless argument and diverting attention from the stated purposes of the group. This study documents a case in which the members of an online community--a feminist web-based discussion forum--are targeted by a "troll" attempting to disrupt their discussion space. We analyze the strategies that make the troller successful and the targeted group largely ineffectual in responding to his attack, as a means to understand how such behavior might be minimized and managed in general. The analysis further suggests that feminist and other nonmainstream online forums are especially vulnerable, in that they must balance inclusive ideals against the need for protection and safety, a tension that can be exploited by disruptive elements to generate intragroup conflict.  相似文献

In this paper, we consider the difficulties that a group of internationally educated female teachers (female IETs) encountered in the process of seeking certification in the Canadian Maritimes. We read their experiences in the context of neoliberalism, in particular how they are positioned in the labour force and also the teaching profession. We consider the material effects of differences such as gender, race, ethnicity, and regional location for the female IETs. Further, we underscore implications for teacher education.  相似文献

This paper describes the implementation and evaluation for scaling up a comprehensive early childhood teacher professional development program into 11 communities across 2 years with funding through state legislative actions. The comprehensive program had four major components based on results from a previous multi-condition random assignment study across four states. The previous results demonstrated that the most optimum approach for supporting children??s school readiness included: (1) teacher on-line professional development with facilitation, (2) classroom mentoring, (3) implementation of a research-based curriculum, and (4) technology-driven progress monitoring that informed instruction. The comprehensive professional development program was evaluated in a new state program designed to bring childcare, Head Start, and public school pre-kindergarten together into integrated partnerships. In Year 1, 220 teachers serving 3834 children were randomly assigned to either receive the comprehensive program or not. Teachers who served as controls in Year 1 received the program in Year 2, and those who received the program in Year 1 participated for an additional year in Year 2, allowing for examination of the effects of one versus 2 years of participation. The program improved teachers instructional practices relative to controls, and a second year of participation resulted in greater gains in children??s language and literacy. Results support the need for well-integrated, comprehensive professional development for early childhood educators.  相似文献

Deaf and hard of hearing children have shown delays and difficulties in pragmatic behaviors due to insufficient exposure to common daily discourse and underlying impoverishment in all components of language development. In a study in a school district in a southeastern U.S. state, the researchers investigated the relationship between sociolinguistic pragmatic competence in 81 deaf and hard of hearing students and these students' degree of hearing loss, communication mode, and degree of success in general education. Two measures, one devised by the state's department of education and one developed within the local school system, were used: the Criterion-Referenced Competency Test (Georgia Department of Education, 2000) and the Socio-Pragmatic Skills Checklist for Deaf and Hard of Hearing Students (Cobb County School District, 1997). The researchers found that whether the students used spoken language or signed language, socio-pragmatic language had a high, positive correlation with academic outcomes.  相似文献

This paper describes the development of a virtual learning environment using a blend of collaborative technologies and human resources to provide US preservice teachers with an authentic experience of another culture. A core design component is the use of ‘embedded instructors’ who are natives of and living in the target country (N. Ireland) while delivering the course in the USA. The wider issue of the potential depersonalisation of online learning is also addressed, and effective strategies for promoting the human dimension and sustaining learner engagement are described. In the context of globalisation, as well as of the constantly increasing provision of online courses, the course model could be of interest to both the academic and the corporate world.  相似文献

Previous research has demonstrated that preschoolers can use situation-specific (e.g., visual access) and person-specific (e.g., prior accuracy) cues to infer what others know. The present studies investigated whether 4- and 5-year-olds appreciate the differential informativeness of these types of cues. In Experiment 1 (N = 50), children used others' prior labeling accuracy as a cue when learning labels for, but not the visual identity of, hidden objects. In Experiment 2 (N = 64), with both cues present, children attended more to visual access than prior accuracy when learning the visual identity of, but not labels for, hidden objects. These findings demonstrate that children appreciate the difference between situation- and person-specific cues and flexibly evaluate these cues depending on what information they are seeking.  相似文献

These studies investigated two hundred and forty-four 24- and 30-month-olds' sensitivity to generic versus nongeneric language when acquiring knowledge about novel kinds. Toddlers were administered an inductive inference task, during which they heard a generic noun phrase (e.g., "Blicks drink milk") or a nongeneric noun phrase (e.g., "This blick drinks milk") paired with an action (e.g., drinking) modeled on an object. They were then provided with the model and a nonmodel exemplar and asked to imitate the action. After hearing nongeneric phrases, 30-month-olds, but not 24-month-olds, imitated more often with the model than with the nonmodel exemplar. In contrast, after hearing generic phrases, 30-month-olds imitated equally often with both exemplars. These results suggest that 30-month-olds use the generic/nongeneric distinction to guide their inferences about novel kinds.  相似文献

Objective

We sought to determine the incidence, clinical features, and demographic profile of head injury secondary to suspected child maltreatment (abuse or neglect) in Canada to help inform the development and evaluation of prevention programs for abusive head injuries.

Methods

From March 1, 2005 to February 28, 2008, an average of 2,545 paediatricians and paediatric subspecialists were surveyed monthly through the established network of the Canadian Paediatric Surveillance Program. We calculated incidence rates using the number of confirmed cases over the product of the duration of the study (3 years) and population estimates by age group.

Results

There were 220 confirmed cases of head injury from suspected child maltreatment. The annual incidence rate was 14.1 per 100,000 for children less than 1 year of age and 1.4 per 100,000 for those less than 15 years. Seventy three percent (141) of cases involved infants less than 12 months of age and 52% (100) of cases involved infants less than 6 months of age. Seventy-five percent (165) of cases presented to the emergency room. With regard to outcome, 12% (27) of cases resulted in death and 45% (75) of survivors had neurological sequelae at discharge. Thirty percent (67) of all cases, as well as 30% (8) of deaths were previously known to child welfare authorities.

Conclusion

This study provides an estimate of the rate of head injury secondary to suspected child maltreatment in Canada. The young age and poor medical outcomes of those involved highlights the need for prevention efforts that are implemented early in life. Given that a significant percentage of injured infants and children were already known to child welfare authorities, the study also highlights the need to establish and evaluate additional preventive efforts for parents and caregivers already in the child welfare system.  相似文献
