GM(1,1) and GM(1,1) rolling models derived from grey system theory were estimated using time-series data from projection studies by National Center for Education Statistics (NCES). An out-of-sample forecasting competition between the two grey prediction models and exponential smoothing used by NCES was conducted for education expenditure and school enrollment under the assumption that grey prediction was as promising as NCES's forecasting technique in dealing with univariate time-series data while some other determinants of the variables under examination were excluded. The purpose of this study, therefore, was to verify that the GM(1,1), and GM(1,1) rolling models would provide forecasts that were at least as accurate as the NCES's approach to extrapolating education expenditure and school enrollment. The findings revealed that the forecasting efficiency of GM(1,1) rolling model was superior to exponential smoothing and GM(1,1) model. The results can offer valuable insights and provide a basis for further research in model building for short-term estimation on educational statistics. 相似文献

Two experiments aim at describing the impact of friendship during a synchronous collaborative information retrieval (SCIR) with young pupils (recruited in Grade 3). In the first study, 68 pupils were asked to look for 13 answers in one of the three following conditions: on an individual basis (condition “Single”), as part of a designed duo with social friendship (condition “Affinity +”), or as part of a designed duo without social friendship (condition “Affinity ?”). In the second experiment, we investigated more precisely the impact of friendship on verbal interactions between partners. Main results obtained in these two experiments are the following: (1) pairs retrieved effectively more answers, more correct answers and were more efficient than singles; (2) pairs composed of pupils without social friendship retrieved more answers, more correct answers and were more efficient than pairs composed by friends; (3) pairs composed of friends produced significantly more irrelevant queries; and (4) pairs composed of friends produced more verbalisations related to conflicts, while pairs composed of pupils without social friendship are engaged in a great deal of consensus seeking. Finally, educational implications are discussed. 相似文献

Software used by book publishers to manage contracts, royalties, production workflow, sales, and marketing have begun to migrate
from relatively closed systems that are internally maintained, to cloud-based platforms on the Web. Business drivers behind
this migration include a highly dynamic market for ebooks and other digital products, pressures to cut costs, and a shrinking
ROI horizon for technology investments. While questions remain as to how quickly the transition will take, the possibility
of cloud-based book publishing promises to change the nature of publishing infrastructure and with it the role of the IT professionals
in publishing. 相似文献

While it is recognised that prior knowledge is a key factor in determining future learning, its influence on learning to teach is less well known. This study investigates two cohorts of teacher candidates studying for a one-year, graduate qualification for primary teaching, who completed two tasks at entry to their initial teacher education programme: a task in writing and a task in mathematics. The tasks focused on teacher candidates' ability to recognise the key features of a piece of student work. The teacher candidates' responses to the tasks highlighted the diverse nature of the prior knowledge that underpinned their responses. The study raises questions about the pedagogy of initial teacher education, particularly in relation to the assumptions teachers educators make about the candidates they teach. The findings suggest that the prior knowledge that students bring to initial teacher education is both a resource and a challenge for teacher educators. 相似文献

Peer feedback is an inherent feature of classroom collaborative learning. Students invariably turn to their peers for feedback when carrying out an investigative task, and this feedback is usually implicit, unstructured and may positively or negatively influence students’ learning when they work on a task. This study explored the characteristics of verbal peer feedback during a collaborative investigative chemistry task involving New Zealand Year 13 students. During the planning stage of the students’ investigation, the discussions of five pairs of students were recorded and then transcribed. Analysis of transcribed verbal data focused on interactions that involved peer feedback along two dimensions, interactive/non-interactive and dialogic/authoritative (Mortimer and Scott, 2003). The findings indicated that although students adopted a predominantly interactive/authoritative communicative approach, with peer feedback as confirmation or evaluation, they are also capable of a more interactive/dialogic exchange, characterised by elaborative peer feedback. We discuss how this dialogic perspective on peer feedback provides an alternative approach to the analysis and study of student–student interactions during science investigations. The findings should be interpreted in light of the limitations in terms of sample size, grouping and specificity of the coding scheme. Implications for teacher practice are discussed in relation to facilitating peer feedback discourse in the science classroom. 相似文献

Growing evidence suggests that child care instability is associated with child behavior problems, but existing studies confound different types of instability; use small, convenience samples; and/or control insufficiently for selection into child care arrangements. This study uses survey and calendar data from the Fragile Families and Child Well-Being Study to estimate the associations between three different types of child care instability—long-term instability, multiplicity, and the use of back-up arrangements—and children's internalizing, externalizing, and prosocial behaviors at age 3, controlling for a large number of child and family background characteristics. Long-term instability between birth and age 3, as measured in both the survey and calendar data, is associated with higher levels of externalizing behavior problems. Current multiplicity at age 3 (as measured by survey data) is associated with higher levels of both externalizing and internalizing behavior problems, but stable multiplicity over time (as measured using calendar data) is not. Finally, the use of back-up arrangements at age 3 is associated with higher levels of internalizing behaviors. We find no consistent differences in these results by the timing of instability, child gender, family income, or type of care. 相似文献

Abstract One question of interdisciplinary education is how to encourage students to draw connections between disciplines and to engage in critical thinking. The authors developed a team-taught interdisciplinary course examining the history and literature of modern revolutions. The first time the course was given, students had difficulty making interdisciplinary connections and did not critically re-examine their assumptions. The authors restructured the course, re-thinking its emphasis, procedures, texts, and assignments, with substantial positive results. They also learned that teachers need to reassess their own ideology and teaching strategies to make interdisciplinary education effective. 相似文献
