This article introduces a new computer conferencing metric called Scan Rate, which is a measure of students' and instructors' online reading speed. The term “scan” refers to the practice of either skimming through a message at an unusually rapid pace or reading a message partially and then stopping before the end is reached. It is proposed that the Scan Rate metric offers a useful way of monitoring how thoroughly students attend to the messages they read. Four analyses illustrate the utility of the metric. These reveal that (1) scan rates increase with message size, (2) students are more likely to scan the messages of their peers than messages written by their instructor, (3) students engage in scanning practices more frequently than instructors, and (4) scan rates are partially a function of class size and class configuration. 相似文献

In this study, we performed a fine grained analysis of writing by children with a specific language impairment (SLI) and examined the contribution of oral language, phonological short-term memory (STM), nonverbal ability, and word reading to three writing constructs (productivity, complexity and accuracy). Forty-six children with SLI were compared with 42 children matched for chronological age, receptive vocabulary (N = 46) and reading decoding (N = 46) on a measure of narrative writing. The SLI group performed worse on all measures compared to children of a similar chronological age. The SLI group produced a greater proportion of orthographic spelling errors than children with similar receptive vocabularies, but were comparable to children matched for reading decoding. The children with SLI showed specific difficulties in the omission of whole words (e.g. auxiliary verbs and subject nouns) and omissions of grammatical morphology (e.g. past tense—ed) reflecting the difficulties shown in their oral language. Receptive grammar made a significant contribution to writing complexity and accuracy. Phonological fluency contributed to writing productivity, such as the production of diverse vocabulary, ideas and content and writing fluency. Phonological STM and word reading explained additional variance in writing accuracy over and above the SLI group’s oral language skills. 相似文献

Adult literacy is a crucial element of community and economic development in South Africa and many developing countries striving to meet Millennium Development Goals. However, few governments invest the recommended 6% of education budgets on programmes for adults. Without resources, volunteer educators and international supporters rely on their own creativity to generate project-based learning. Freirian pedagogy and the New Literacy Studies, which theorizes literacy practices grounded in the meaning of daily life, inform this study. This article documents a photovoice project for literacy development in Soweto, South Africa. The project was an initiative stemming from international and cross-cultural collaboration between two women, Geraldine Monama, the literacy coordinator at Orlando East library in Soweto, and Strawn, a community development and adult literacy researcher from the United States. We report what we learned from the project and details of the collaborative process to support similar efforts. 相似文献

Intellectual disability (ID) is associated with a range of risk factors that make children more vulnerable to adverse developmental outcomes, including mental health problems. Nevertheless, some children with ID do much better than others, presumably because of the presence of protective factors that increase their resilience. The current study compared resiliency profiles of children with ID (n = 115; mean age, 11.9 years) and their typically developing peers (n = 106; mean age, 11.8 years) using the Resiliency Scales for Children and Adolescents and the Healthy Kids Resilience Assessment. In many respects, children with ID and their typically developing peers reported similar levels of the protective factors that are associated with resilience. However, the children with ID reported higher levels of emotional sensitivity and lower tolerance, as well as fewer future goals. Compared with typically developing children, those with ID reported more support at school and less support within their communities. These findings have important implications for interventions that aim to promote positive developmental outcomes and to prevent the adverse sequelae that have been associated with low intelligence. 相似文献

ABSTRACTMuch of the research on how social media is embedded into the educational practices of higher education students has a Western orientation. In concentrating on a case study of the varied ways in which African International Distance Education (IDE) students actively use social media to shape their learning experiences, we discuss an under-researched group. The paper draws on analysis of 1295 online questionnaires and 165 in-depth interviews with IDE students at UNISA, South Africa, one of the largest providers of IDE globally. WhatsApp emerges as ‘the’ key social media tool that opens up opportunities for IDE students to transfer, translate and transform their educational journey when studying ‘at a distance’. Although WhatsApp does provide a ‘space of opportunity’ for some students, this is framed through socio-technical marginalisation, itself a reflection of demographic legacies of inequality. Exploring social media practices though the case of African IDE students places these students centre stage and adds to the awareness of the multiple centres from which international education is practiced. 相似文献

At least since the seventeenth century, the strange combination of epistemological certainty and ontological power that characterizes mathematics has made it a major focus of philosophical, social, and cultural negotiation. In the eighteenth century, all of these factors were at play as mathematical thinkers struggled to assimilate and extend the analysis they had inherited from the seventeenth century. A combination of educational convictions and historical assumptions supported a humanistic mathematics essentially defined by its flexibility and breadth. This mathematics was an expression of l'esprit humain, which was unfolding in a progressive historical narrative. The French Revolution dramatically altered the historical and educational landscapes that had supported this eighteenth-century approach, and within thirty years Augustin Louis Cauchy had radically reconceptualized and restructured mathematics to be rigorous rather than narrative. 相似文献

In this study we examined the effect of heart rate and behavioral measures of attention on distractibility of 6-, 9-, and 12-month-old infants. The infants were presented with a toy, and a distractor was presented while they attended to the toy. The distractor was presented during heart rate changes indicating sustained attention or attention termination, or during periods of time when behavioral ratings indicated the infant was in focused or casual attention. There were longer distraction latencies during attentional engagement as defined by heart rate changes or behavioral ratings than for periods of inattention. Infants had the longest distraction latencies when heart rate and behavior measures were congruent with respect to attention engagement (heart rate deceleration and focused attention). Conversely, latencies were shortes for congruent values of inattention (heart rate acceleration and casual attention). Infant information processing may be greatest when a heart rate deceleration occurs simultaneously with an episode of focused attention. 相似文献

The focus of workplace communication research on visual rhetoric has tended to be the efficient and unproblematically “effective” functioning of visual texts. By suggesting ways in which the visual representations of science are construed by expert readers, this article responds to a call within our discipline for more critically focused contributions to the study of visual literacy. A former editor-in-chief of the American Journal of Botany was asked to explain his interpretation of visuals appearing over an 80-year period in that journal; his responses illustrate how visual explanations testify to their creators' authority and how, once established, such authority actuates the rational arguments of science. Rhetorical appeals within and arrangement of visual texts are considered, as is the persuasive power of legends and captions. 相似文献

This article presents a theoretical overview of the complementary relationship between open education and environmental design. An elementary education program called the Open Corridor serves as a concrete example. The Open Corridor program dovetailed many aspects of open education and environmental design. Students, teachers, administrators, parents, and consulting psychologists served in the roles of planner and implementer. A review of open education and environmental design approaches is followed by a sketch of the Open Corridor program and a discussion of issues. A bright future exists for programs that carefully open their educational processes and plan their environments. 相似文献
