AbstractData center infrastructures provide a lens for understanding the rise of resilience thinking, for grasping the pragmatism and promise of resilience as approach. Unable to anticipate every threat and lockout every contingency, developers of resilient infrastructure “design in” failure, automate monitoring and maintenance, and build capacity to flexibly adapt to new threats. In enacting resilience in the present, they anticipate possible futures, prototyping forms of future life. In this sense, infrastructures should also be understood as operational imaginaries – as systems that powerfully suggest a set of future possibilities by enacting them concretely in the present. 相似文献

This article reports on a study conducted in a graduate teacher research class with elementary and secondary classroom teachers. Wanting to create a collaborative environment in which their students could use language to support each other's learning, the instructors formed discourse groups. The article introduces a theoretical framework for discourse groups and using examples from the groups, presents a methodology for analyzing the social practices reflected in the teachers’ talk. It concludes with a discussion of the nature of the discourse that supported (and in some cases did not support) the re-storying of teachers’ knowledge. 相似文献

Researchers agree that achieving thefundamental changes called for by currentreforms in mathematics education requires newlearning on the part of teachers. Currently,across the United States there exists atremendous variety of teacher-enhancementprojects representing a range of perspectivesand approaches to supporting teachers'learning. This paper presents a comparativeanalysis of three teacher educators using acurriculum designed for use with elementaryteachers in an inquiry-group setting. The aimof the study was to examine the process anddemands of supporting teachers' learning andteachers' efforts to reform their practices. Analyses revealed that the central demand ofsupporting teachers' learning through inquiryinvolved navigating through what we have calledopenings in the curriculum. Theseopenings took the form of unanticipatedquestions, challenges, observations, or actionsby participating teachers that requiredfacilitators to make on-the-spot judgmentsabout how to guide the discourse. Examinationsof the facilitators' processes of navigatingthese openings revealed a set of threeactivities they employed in determining how torespond. Analysis of the activities offacilitators in response to openings furtherilluminates the work involved in supportingteachers' learning and has implications for theskills needed by teacher educators engaged inthis work. 相似文献

This study examined whether children’s learning from “Sesame Street” could be improved by having adults ask the children questions
and provide them with feedback while they watched the show. Subjects were 23 three- and four-year-old, white, middle-class
children who were randomly assigned to one of two conditions. Children in both conditions watched three specially edited versions
of “Sesame Street” with an adult. While they did so, children in the experimental condition were asked to name the letters
and numbers shown on the programs. Results indicated that 3 days after watching the last program, children in the experimental
condition were better able to name and identify the letters and numbers they had seen (p < .01). Three features of the experimental
treatment that may have contributed to these results are discussed, as are the implications of the findings. 相似文献

Economic Deprivation and Early Childhood Development 总被引:53,自引:0,他引:53
We consider 3 questions regarding the effects of economic deprivation on child development. First, how are developmental outcomes in childhood affected by poverty and such poverty correlates as single parenthood, ethnicity, and maternal education? Second, what are the developmental consequences of the duration and timing of family economic deprivation? And, third, what is the comparative influence of economic deprivation at the family and neighborhood level? We investigate these issues with longitudinal data from the Infant Health and Development Program. We find that family income and poverty status are powerful correlates of the cognitive development and behavior of children, even after accounting for other differences—in particular family structure and maternal schooling—between low- and high-income families. While the duration of poverty matters, its timing in early childhood does not. Age-5 IQs are found to be higher in neighborhoods with greater concentrations of affluent neighbors, while the prevalence of low-income neighbors appears to increase the incidence of externalizing behavior problems. 相似文献

This paper contrasts two types of “autodidact” located in the UK in different historical periods, which utilised different learning/research technologies to different ends. From the 1920s to the 1960s some working-class activists committed to the Communist Party of Great Britain became “educated” in Marxism (and more) through the processes intrinsic to their politics. This radical acculturation was undertaken outside the universities in consequence of both an absence of access to higher education and because of the relatively enclosed social world of British Communism. The widening of educational opportunities and the decline of political Marxism effectively extinguished this kind of autodidact. New technologies have meant that the 21st century is witnessing individuals and cyber-communities that are creating knowledge-based challenges to professional and institutional power in the face of personal/family “medical” crises. The paper outlines the characteristics of these two categories of autodidact and a new terrain of counter-hegemonic learning. 相似文献

For several decades researchers have raised questions regarding factors that enable undergraduate students, particularly those from ethnic minority groups living in low socio-economic areas, to persist with their studies to degree completion. Seeking answers to these questions becomes more urgent as universities around the world enrol increasingly diverse cohorts of students. This article reviews the patterns of participation and success for students enrolled in a Bachelor of Education program at one university, distributed across three different locations and attracting different cohorts of students. This provided the university with a unique opportunity to learn about the retention and success of diverse cohorts, particularly those traditionally under-represented at undergraduate-level study. At least 75% of students in the under-represented groups passed their courses. Surprisingly the pass rates of students at the three campuses were similar, despite dissimilarities in ethnicity, socio-economic status and previous academic success. 相似文献

This study examined the predictive utility of five formative reading measures: words correct per minute, number of comprehension questions correct, reading comprehension rate, number of maze correct responses, and maze accurate response rate (MARR). Broad Reading cluster scores obtained via the Woodcock–Johnson III (WJ III) Tests of Achievement served as the criterion variable. Examiners administered all reading measures to 98 students enrolled in upper elementary (UES) and middle school (MS) grades (grades 4 through 8). Results indicated significant intercorrelations within all predictor variables for the combined and UES samples; fewer intercorrelations existed at the MS level. MARR exhibited the highest correlation with WJ III Broad Reading across all correlational analyses. Additional regression analyses indicated that the MARR technique best predicted WJ III Broad Reading cluster scores across all groups analyzed. Limitations of the current study and suggestions for future research are discussed. 相似文献

Many studies have found gender differences in certain areas of academic achievement, such as reading and math. Fewer studies have examined gender disparities in writing skills. The current study explored gender differences in written expression performance. Participants were 1,240 male and female students in third through eighth grade, representing five schools in a rural southeastern school district. Each student was administered an AIMSweb curriculum‐based measurement writing probe during the district's regularly scheduled fall, winter, and spring benchmarks. All measures were scored for total words written and correct writing sequences. Two‐way repeated measures analyses of variance were used to determine whether differences existed in the sample. A significant female advantage was found on both scoring indices at each grade level. These findings have strong instructional and theoretical implications for practicing school psychologists and other educators. 相似文献
