Do You Know What It Means to Miss New Orleans? Internet Communication, Geographic Community, and Social Capital in Crisis 总被引:1,自引:0,他引:1

This study investigated Internet communication and use in a crisis situation, Hurricane Katrina, to explore the role of the Internet in supporting or diminishing geographically-based community during a crisis. The researchers conducted an online survey of Internet users (n=1192) from the dispersed metropolitan New Orleans area. The survey focused on amount, type, function, and importance of Internet use to creating and maintaining social capital, supporting geographically-based communities, activating social networks, reducing uncertainty, and achieving both expressive and instrumental communication goals. The results indicated that Internet users in a crisis situation went online to seek interactive fora specific to their neighborhoods and to activate weak ties in their social networks. They engaged in more uncertainty reduction behavior when experiencing higher degrees of damage. They turned to the Internet in place of other media as a result of disruptions caused by the crisis. Women valued online expressive communication more than men did. The findings suggest that social capital theorists would benefit from a communication perspective on the Internet. The study also led to the formation of suggestions for emergency preparedness agencies, shelter providers, crisis victims, and online news providers that can improve emergency response. 相似文献

This qualitative case study examined Twitter use by undergraduate and graduate students in three classes. Previous studies have shown that while some faculty use Twitter, few are incorporating it into classes despite many recommendations for such use. This study examined how students perceived Twitter as a classroom tool. As an optional activity, many started with Twitter but fewer continued through the semester. The study reports on content and counts of tweets as well as student self-reports on usage and interest. The researchers found students enjoyed being consumers of tweets but seldom retweeted or replied. Incorporating Twitter in courses will require careful consideration of scaffolding, modeling, privacy and course design. Questions remain as to whether the informal social focus of Twitter may overwhelm attempts to use it in more structured educational settings. 相似文献

Children with developmental coordination disorder (DCD) experience difficulty coping with everyday demands due to difficulties
in performing motor tasks. Recently, a cognitive learning paradigm has been applied to studying the nature of the problems
experienced by children with DCD, which assumes that these children have fewer cognitive and metacognitive skills with which
to acquire motor skills. However, despite the emergence of such cognitive models, individual differences in children’s use
of self-regulatory and metacognitive skill during motor learning have received little research attention. The aim of this
review article was to examine the roots of this emerging field of research, locate it within the larger body of metacognitive
and self-regulation literature, and examine some of the preliminary work that has been conducted on the role of self-regulation
and metacognition in motor learning and in the motor performance difficulties of children with DCD. 相似文献

In this paper we report the results of a study which investigated the affordances of multi-user virtual environments (MUVEs)
for collaborative learning from a design perspective. Utilizing a mixed methods approach, we conducted a comparative study
of the effect of varying representational and interactional design features on a collaborative design activity in three online
synchronous environments. We compared environments featuring multiple modes of interaction (MUVEs), shared representations
(text chat and 2D still images) and text-only features. Sixty-one students enrolled in an undergraduate course on Child Development
participated in the study. Participants were asked to design a theoretically-based, developmentally appropriate, preschool
classroom setting. Students were randomly assigned to one of three online learning environments that provided varying levels
of representation and interaction. Significant differences in collaborative problem solving interactions were found. Participants
in the shared representations + text condition evidenced stronger learning outcomes as regards substantive discussion and
integration of child development concepts; while participants in the MUVE condition reported the most enjoyment with the experience.
These findings are explained by the concepts of representational guidance, representational bias, educational affordances
and interface design metaphors. Suggestions for the design of MUVEs for collaborative learning are provided. 相似文献

There is growing concern over the number of young children who display challenging behavior and preschool teachers are reporting
children’s challenging behavior as their greatest concern. Program-wide Positive Behavior Support (PWPBS) is a promising model
for supporting appropriate behavior and decreasing challenging behavior in early childhood programs. Implementation in early
childhood settings is relatively new and guidance on how to implement PWPBS in early childhood settings is growing. This article
documents the implementation process for an early childhood program serving children from 6 weeks to 5 years of age, shares
lessons learned and offers practical advice for getting started with PWPBS. 相似文献

Defending peers who have been bullied is often thought to put defenders at risk of becoming victimized themselves. The study investigated the concurrent and prospective associations between defending and (peer- and self-reported) victimization, and examined popularity and classroom norms as potential moderators. Participants included 4085 Finnish youth (43.9% boys; Mage = 14.56, SD = .75; 97% born in Finland). Concurrently, defending was positively associated with self-reported victimization in classrooms with high bullying-popularity norms (b = .28, SE = .16). Defending was negatively associated with peer-reported victimization in classrooms with high defending-popularity norms (b = −.07, SE = .03). Defending was not significantly associated with future victimization, suggesting that it is generally not a risk factor for victimization. 相似文献

Increasing number of medical students and limited availability of cadavers have led to a reduction in anatomy teaching through human cadaveric dissection. These changes triggered the emergence of innovative teaching and learning strategies in order to maximize students learning of anatomy. An alternative approach to traditional dissection was presented in an effort to improve content delivery and student satisfaction. The objective of this study is to acquire three-dimensional (3D) anatomical data using structured-light surface scanning to create a dynamic four-dimensional (4D) dissection tool of four regions: neck, male inguinal and femoral areas, female perineum, and brachial plexus. At each dissection step, identified anatomical structures were scanned using a 3D surface scanner (Artec Spider™). Resulting 3D color meshes were overlaid to create a 4D (3D+time) environment. An educational interface was created for neck dissection. Its implementation in the visualization platform allowed 4D virtual dissection by navigating from surface to deep layers and vice versa. A group of 28 second-year medical students and 17 first-year surgery residents completed a satisfaction survey. A majority of medical students (96.4%) and 100% of surgery residents said that they would recommend this tool to their colleagues. According to surgery residents, the main elements of this virtual tool were the realistic high-quality of 3D acquisitions and possibility to focus on each anatomical structure. As for medical students, major elements were the interactivity and entertainment aspect, precision, and accuracy of anatomical structures. This approach proves that innovative solutions to anatomy education can be found to help to maintain critical content and student satisfaction in anatomy curriculum. 相似文献
