    Assessing School Turnarounds: Using an Integrative Framework to Identify Levers for Success

    Get PDF
    Proposing an integrative framework that links Bryk and colleagues’ five essential supports for school improvement and Porter and colleagues’ policy attribute theory, I use a mixed-methods approach to study the implementation and effectiveness of school turnaround efforts in the School District of Philadelphia. Using a matched comparison design and estimating a series of regression models to analyze data from Philadelphia’s central school improvement models as well as a group of comparison schools, I explore the relationships among key model components, approaches to implementing these components, and academic achievement. The use of an integrative framework for school improvement facilitates the unpacking of the idea of “success” in school reform, and careful examination of key reform components and implementation strategies provides insights into why particular school improvement models are (or are not) associated with gains in academic achievement. Qualitative methods are used to contextualize these findings and offer hypotheses to explain variation in essential supports, policy attributes, and achievement outcomes. This study facilitates the development of an empirically grounded theory of how implementation relates to effectiveness that proves useful in evaluating school turnaround, and in assessing how policymakers and implementers might leverage various aspects of implementation to create effective school improvement models at scale. Ultimately this study finds that how improvement models are implemented is more important than what key components models use in terms of explaining improvements in student achievement

    Incommensurate chirality density wave transition in a hybrid molecular framework

    Full text link
    Using single-crystal X-ray diffraction we characterise the 235\,K incommensurate phase transition in the hybrid molecular framework tetraethylammonium silver(I) dicyanoargentate, [NEt4_4]Ag3_3(CN)4_4. We demonstrate the transition to involve spontaneous resolution of chiral [NEt4_4]+^+ conformations, giving rise to a state in which molecular chirality is incommensurately modulated throughout the crystal lattice. We refer to this state as an incommensurate chirality density wave (XDW) phase, which represents a fundamentally new type of chiral symmetry breaking in the solid state. Drawing on parallels to the incommensurate ferroelectric transition of NaNO2_2 we suggest the XDW state arises through coupling between acoustic (shear) and molecular rotoinversion modes. Such coupling is symmetry-forbidden at the Brillouin zone centre but symmetry-allowed for small but finite modulation vectors q=[0,0,qz]∗\mathbf q=[0,0,q_z]^\ast. The importance of long-wavelength chirality modulations in the physics of this hybrid framework may have implications for the generation of mesoscale chiral textures, as required for advanced photonic materials.Comment: 5 pages, 3 figure

    Joining hands in hope: an autoethnographical analysis of a non-Indigenous educator engaging in Indigenous pedagogy

    Get PDF
    I am a South African who is now a Canadian, with lived experience in both Indigenous contexts. I use these experiences as a springboard into an autoethnography about me as a non-Indigenous educator, understanding authentic relations in Indigenous contexts. I use stories, poetry, reflections and academic literature braided together as an exploration of self in relation to Indigeneity, and a discussion of implications for other non-Indigenous educators working in Indigenous contexts. Within this thesis, I use the word Indigenous as meaning a group of people who were first on any particular piece of land and have lived on it continuously

    Participatory evaluation of co-management in wet tropics country: interim report

    Get PDF
    This technical report contributes to the December 2013 Milestone for the National Environmental Research Program (NERP) Tropical Ecosystem Hub (TEH) Project 12.1 Indigenous co-management and biodiversity protection. The overall goal of this co-research is to interrogate the capability of Indigenous Protected Areas (IPAs) and other collaborative planning models and mechanisms to provide the means for effective engagement of Indigenous knowledge and comanagement for biodiversity and cultural protection in the region; and to provide for joint management of the Wet Tropics World Heritage Area between governments and Rainforest Aboriginal people, in partnership with communities. Our definition of co-management as a continual solution-building process, not a fixed state, involving extensive talking, negotiating together and jointly learning so it gets better over time, underpins our derived framework of comanagement (see Fig 2). This framework, that includes thirteen separate but related parts that can be grouped into two features of co-management (Rainforest Aboriginal Peoples Keeping Strong; and Keeping Engagement Strong), guides the participatory evaluation shared in this report. The framework was refined from earlier project work (see Maclean et al, 2012), ongoing discussions with the project co-research team and a regional participatory workshop held in October 2012 (Hill et al. 2012). The results reported here are located within the second phase of a three year co-research project, providing an interim participatory evaluation of co-management in wet tropics country, NE Australia1. Both qualitative and a quantitative data contribute to the evaluation which was conducted together with Rainforest Aboriginal peoples in two separate workshops. Workshop one was hosted by Girringun Aboriginal Corporation in Cardwell on 23 November 2013, and brought forward data informed by the nine tribal groups that are represented therein. Workshop two was hosted by the Rainforest Aboriginal People’s Alliance as part of the ‘Warrama: for Rainforest Country, Kin and Culture’ held at Genzanno 28 November-1st December 2013. This workshop brought forward data informed by the wider twenty tribal groups across the region of wet tropics country. A health rating of 1 to 5 (where 1=very sick; 5=excellent health) was given to three indicators (structures, processes and results) for each part of the framework at both workshops, and the reasons for the ratings discussed in small groups. This Interim Report presents a quantitative analysis of data from both the Girringun and RAP Workshops, but qualitative and spatial analysis of only the Girringun data. The short time frame between the regional RAP workshop and the data for report submission did not allow for a full analysis of the data, which will be included in the Final Participatory Evaluation Report in June 2014. This Final Report will also include data from participatory workshops with governments and other partners involved in co-management of wet tropics country Both the Girringun and RAP workshops evaluated the structures, processes and results for the Rainforest Aboriginal Peoples Keeping Strong parts of the framework as in better health than thethose for Keeping Engagement Strong. The results of participatory evaluations reported here resonate with the concept of the creation of an equitable intercultural space as the key means of achieving co-management (Hibbard et al. 2008; Hill 2011). Indigenous Protected Areas were identified as the most useful tool for creating an equitable intercultural space, due to their\adaptability and flexibility, providing opportunities for effective collaboration with government and others

    A protocol for an individualised, facilitated and sustainable approach to implementing current evidence in preventing falls in residential aged care facilities

    Get PDF
    Background. Falls are common adverse events in residential care facilities. Commonly reported figures indicate that at least 50% of residents fall in a 12 month period, and that this figure is substantially higher for residents with dementia. This paper reports the protocol of a project which aims to implement evidence based falls prevention strategies in nine residential aged care facilities (RACFs) in Australia. The facilities in the study include high and low care, small and large facilities, metropolitan and regional, facilities with a specific cultural focus, and target groups recognised as being more challenging to successful implementation of falls prevention practice (e.g. residents with dementia). Methods. The project will be conducted from November 2007-November 2009. The project will involve baseline scoping of existing falls rates and falls prevention activities in each facility, an action research process, interactive falls prevention training, individual falls risk assessments, provision of equipment and modifications, organisation based steering committees, and an economic evaluation. In each RACF, staff will be invited to join an action research group that will lead the process of developing and implementing interventions designed to facilitate an evidence based approach to falls management in their facility. In all RACFs a pre/post design will be adopted with a range of standardised measures utilised to determine the impact of the interventions. Discussion. The care gap in residential aged care that will be addressed through this project relates to the challenges in implementing best practice falls prevention actions despite the availability of best practice guidelines. There are numerous factors that may limit the uptake of best practice falls prevention guidelines in residential aged care facilities. A multi-factorial individualised (to the specific requirements of each facility) approach will be used to develop and implement an action plan in each participating facility based on the best available evidence

    Open Food Network: the Role of ICT to Support Regional Food Supply Chains in Australia

    Get PDF
    Many organizations have introduced various ICT-enabled innovations to improve economic, environmental and social performance. The Open Food Network (OFN) is an example of an ICT enabled innovation that has the potential to enhance the sustainability of regional food supply chain by improving farmers’ access to local and regional markets and consumers’ access to fresh local produce, as well as optimizing the regional food distribution and improving local community welfare. OFN has just been recently launched in Australia and currently there is a limited understanding of the actual impacts. This research-in-progress paper aims to evaluate the effectiveness of the OFN system in connecting and supporting the sustainability of regional food supply chain communities in Australia that will help devise strategies for expanding the use beyond Australia. The findings contribute to a longer term research program that investigates how ICT can support sustainability initiatives within organizations and supply chains

    Discipline in Context: Suspension, Climate, and PBIS in the School District of Philadelphia

    Get PDF
    The report details a two-year exploratory, mixed-methods research study on the disciplinary practices and climate of schools serving K–8 students in the School District of Philadelphia (SDP). Findings reveal that SDP schools are making efforts to reduce suspensions and improve climate, but critical barriers to these efforts include resource limitations and philosophical misalignments between teachers and school leaders. The study identified three profiles among SDP schools serving K–8 students based on information about disciplinary practices and climate, and found that these profiles are predictive of suspension and academic outcomes. Students attending schools with collaborative climates and less punitive approaches to discipline have lower risk of being suspended and better academic outcomes. The report offers a series of recommendations for strengthening the implementation of climate initiatives, including Positive Behavioral Interventions and Supports (PBIS), in challenging urban settings
