In this article we discuss how school leaders address challenges when implementing innovative international education curricula, namely International Baccalaureate (IB) programs. Specifically, we frame challenges in curriculum implementation of and transition between IB programs from a “disconnection” perspective. We have often noticed when innovative programs are parceled together without preparation and thrust at great speed at schools, they become disconnected. The hasty implementation of multiple IB programs simultaneously at a school also causes disconnection. Drawing on extensive interview data from principals, mid-level leaders, and teachers in five IB schools adopting multiple IB programs in Asia, we detail curriculum disconnection facing IB schools and how school leaders, including teacher leaders, address such challenges by weaving various disconnected points, namely instrumental, intellectual, cultural, professional, and communicative disconnections. Based on findings from the multisite case study, we argue that school leaders in the case of IB schools adopt a range of leadership strategies to weave disconnection points. We reframe the leadership strategies as two aspects of distributed leadership: distributed instructional leadership and teacher leadership. In conclusion, we suggest that a central facet for successful leadership of IB schools that adopt multiple IB programs is about finding, focusing, and facilitating ways to address disconnections in curriculum implementation of and transition between different IB programs. 相似文献

Using a teacher recruitment and preparation model, a unique partnership between PK–12 schools, a community college, and a university is examined. The focus is on the training and credentialing of future educators, particularly from underrepresented backgrounds, in an efficient and quality manner to assist in meeting the current PK–12 teacher shortage. Data indicate that the partnership is progressing towards, or has met, its targets in addressing said shortage. 相似文献

The paper combines a comprehensive account of the probabilistic model of retrieval with new systematic experiments on TREC Programme material. It presents the model from its foundations through its logical development to cover more aspects of retrieval data and a wider range of system functions. Each step in the argument is matched by comparative retrieval tests, to provide a single coherent account of a major line of research. The experiments demonstrate, for a large test collection, that the probabilistic model is effective and robust, and that it responds appropriately, with major improvements in performance, to key features of retrieval situations.Part 1 covers the foundations and the model development for document collection and relevance data, along with the test apparatus. Part 2 covers the further development and elaboration of the model, with extensive testing, and briefly considers other environment conditions and tasks, model training, concluding with comparisons with other approaches and an overall assessment.Data and results tables for both parts are given in Part 1. Key results are summarised in Part 2. 相似文献

OBJECTIVE: The aim of this study was to examine the trajectory of cases through four systems: child protection, law enforcement, the dependency courts, and the criminal courts. METHOD: This study focused on a county selected from a 41-county telephone survey conducted for the National Incidence Study of Child Abuse and Neglect (NIS-3). For this analysis prospective samples were drawn from law enforcement (n=225) and the county child protection (CPS) agency (n=225) and followed through in-depth case tracking across all agencies and through both the dependency and criminal court systems. RESULTS: The percentage of CPS cases opened in dependency court was similar to prior studies (29%), but the acceptance and prosecution rates were much higher--92% of the cases referred from CPS, including many cases of physical abuse. Compared to referrals from CPS to law enforcement (93%), few cases were referred from law enforcement to CPS (17%). Anecdotally, case referral patterns appeared to be influenced by communication patterns and mutual positive regard, regardless of the collaborative protocols in place. One of the most instructive findings was the degree of difficulty in tracking cases across organizations and the types of obstacles that impeded success. Disorganization was not an issue, rather internal structures set up to facilitate intra-organizational processing were the same structures that actually impeded cross-organizational case finding. CONCLUSIONS: It is not sufficient to rely on the existence of multi-disciplinary teams or Child Advocacy Centers to ensure collaboration. More attention to daily tasks and activities as well as the nature and quality of communication is warranted. On the technical side, use of common case identifiers on cases that are cross-referred is strongly recommended. Future studies should broaden the scope of inquiry to include the consequences of all case trajectories, rather than solely focusing on the justice system. 相似文献

As part of a large‐scale study of the ability of 94 secondary schools to promote academic achievement, case studies of six outlier schools were conducted and headteachers (principals) and their deputies were questioned about the processes of effectiveness. The analysis of their responses ‐ grouped by the performance of their school (measured by value added analyses of three years of public examination results) as effective, ineffective or mixed ‐ reveals considerable support for previously cited characteristics of effective schooling. Despite the limitations imposed by a reliance on the use of retrospective accounts, the study takes forward the field of school effectiveness in its search for generalisable findings and coherent theory. 相似文献

Measurements of formal reasoning and principled moral reasoning ability were obtained from a sample of 99 tenth grade students. Specific modes of formal reasoning (proportional reasoning, controlling variables, probabilistic, correlational, and combinatorial reasoning) were first examined. Findings support the notion of hierarchical relationships which exist among those variables. Further results from factor analysis provide evidence that the variables represent specific cognitive structures that are interdependent with each other and precede operations in development. Finally, significant relationships were found to exist between the different modes of formal reasoning and principled moral reasoning. Combinatorial and correlational reasoning were found to significantly account for 22% of the variance in principled moral reasoning. Theoretical and educational implications are discussed. 相似文献

Based on technological and analytical advances, the capability to more accurately and finitely examine biomechanical and skill characteristics of movement has improved. The purpose of this study was to use Inertial Measurement Units (IMUs) and Functional Principal Components Analysis (fPCA) to examine the role of movement variability (assessed via angular velocity), on 2 divers (1 international level; 1 national) performing the forward 3½ pike somersault dive. Analysis of angular velocity curves during ive-flight identified 5 fPCs, accounting for 96.5% of movement variability. The national diver’s scatter plots and standard deviation of fPC scores illustrated larger magnitudes of angular velocity variability across dive flight. For fPC1 and fPC3, magnitudes of SD variability were 282.6 and 201.5, respectively. The international diver illustrated more consistent angular velocity profiles, with clustering of fPCs scores (e.g., fPC1 & 3 = SD’s of 75.2 & 68.0). To account for lower variability in the international diver, the ability to better coordinate movement sequences and functionally utilise feedback in response to initiation of the somersault position is highlighted. Overall, findings highlight how both IMUs and fPCA can more holistically and finitely examine the biomechanical and skill characteristics of movement sequences with the capability to inform athlete development. 相似文献
