Participatory Pattern Workshops Resource Kit
Resource KitThis document describes the methodology that has emerged from a series of workshops we have facilitated over several years. These workshops brought together practitioners from a wide range of fields and engaged them in intense conversations about issues regarding technology and education. Such conversations are rooted in participants personal experiences, driven by the problems they have overcome, and aimed at collaborative articulation of their design knowledge; knowledge of how to get things done. We call these workshops Collaborative Reflection Workshops. Our process goes beyond a single workshop. Over the years, we have identified a structure of three consecutive workshops; a Design Narratives Workshop, a Pattern Mining Workshop and a Design scenarios Workshop. Together, these form what we call the Participatory Patterns Workshops framework. If you are about to participate in such a workshop, this document will tell you what to expect and how to maximise your benefits from the event. If you would like to run such a workshop (or series of workshops) yourself, this document should give you a good starting point for their design. You will still need to adapt the framework for your own needs and circumstances, and we will be happy to assist you in doing that. Everything presented here is a reflection of work in progress. If you find this document useful, please check for new versions. If you find some mistakes or gaps, please let us know. If you run a workshop, please share your experience and insight with us
Participatory pattern workshops: a methodology for open learning design inquiry
In order to promote pedagogically informed use technology, educators need to develop an active, inquisitive, design-oriented mindset (Laurillard, 2008). Design Patterns have been demonstrated as powerful mediators of theory-praxis conversations (Goodyear et al., 2006) yet widespread adoption by the practitioner community remains a challenge. Over several years, the authors and their colleagues have facilitated many workshops in which participants shared experiences, captured these as design narratives, extracting design patterns and applied them to novel teaching challenges represented as design scenarios (Winters &Mor, 2009; Mor &Winters, 2008). This paper presents the core elements of the methodology that emerged from these workshops: the Participatory Patterns Workshops (PPW) methodology
A preferred vision for administering secondary schools : a reflective essay
This paper will examine how the role of the administration, teachers, community, and students, communication, staff development, and safety all affect the school\u27s climate and culture. As Lyman (2000) found, the culture of a school has important and far-reaching effects on the thinking and actions of students and teachers (p. 145)
Indexing: Narrating Interdisciplinary Connections in the Classroom
An integrative tool that we have piloted in two LCs, the interdisciplinary index, is an integrative template that students use to make connections between disciplines. In the learning community, âCli-Fi: Stories and Science of the Coming Climate Apocalypse,â faculty developed the Climate-Change Stress Index (CCSI) that students used to identify evidence of climate-change impacts in the fictional setting of each novel they read. In another learning community, âAll things Connect: Living with Nature in Mind,â students again used an index consisting Ecopsychology principles to describe, explain, and/or evaluate how these principles informed excerpts from environmental literature. We present a variety of student samples using Barberâs (2012) model of integrative learning and conclude with a review of the functions of interdisciplinary indexing
Gap Formation by Planets in Turbulent Protostellar Disks
The processes of planet formation and migration depend intimately on the
interaction between planetesimals and the gaseous disks in which they form. The
formation of gaps in the disk can severely limit the mass of the planet and its
migration toward the protostar. We investigate the process of gap formation
through magnetohydrodynamic simulations in which internal stress arises
self-consistently from turbulence generated by the magnetorotational
instability. The simulations investigate three different planetary masses and
two disk temperatures to bracket the tidal (thermal) and viscous gap opening
conditions. The results are in general qualitative agreement with previous
simulations of gap formation, but show significant differences. In the presence
of MHD turbulence, the gaps produced are shallower and asymmetrically wider
than those produced with pure hydrodynamics. The rate of gap formation is also
slowed, with accretion occurring across the developing gap. Viscous
hydrodynamics does not adequately describe the evolution, however, because
planets capable of producing gaps also may be capable of affecting the level
MHD turbulence in different regions of the disk.Comment: accepted by Astrophysical Journal. For associated animations see

Spatial risk factors for Pillar 1 COVID-19 excess cases and mortality in rural eastern England, UK
Understanding is still developing about spatial risk factors for COVID-19 infection or mortality. This is a secondary analysis of patient records in a confined area of eastern England, covering persons who tested positive for SARS-CoV-2 through end May 2020, including dates of death and residence area. We obtained residence area data on air quality, deprivation levels, care home bed capacity, age distribution, rurality, access to employment centers, and population density. We considered these covariates as risk factors for excess cases and excess deaths in the 28 days after confirmation of positive Covid status relative to the overall case load and death recorded for the study area as a whole. We used the conditional autoregressive BesagâYorkâMollie model to investigate the spatial dependency of cases and deaths allowing for a Poisson error structure. Structural equation models were applied to clarify relationships between predictors and outcomes. Excess case counts or excess deaths were both predicted by the percentage of population age 65 years, care home bed capacity and less rurality: older population and more urban areas saw excess cases. Greater deprivation did not correlate with excess case counts but was significantly linked to higher mortality rates after infection. Neither excess cases nor excess deaths were predicted by population density, travel time to local employment centers, or air quality indicators. Only 66% of mortality was explained by locally high case counts. Higher deprivation clearly linked to higher COVID-19 mortality separate from wider community prevalence and other spatial risk factors
Survivorship and Growth in Staghorn Coral (Acropora cervicornis) Outplanting Projects in the Florida Keys National Marine Sanctuary
Significant population declines in Acropora cervicornis and A. palmata began in the 1970s and now exceed over 90%. The losses were caused by a combination of coral disease and bleaching, with possible contributions from other stressors, including pollution and predation. Reproduction in the wild by fragment regeneration and sexual recruitment is inadequate to offset population declines. Starting in 2007, the Coral Restoration Foundationâą evaluated the feasibility of outplanting A. cervicornis colonies to reefs in the Florida Keys to restore populations at sites where the species was previously abundant. Reported here are the results of 20 coral outplanting projects with each project defined as a cohort of colonies outplanted at the same time and location. Photogrammetric analysis and in situ monitoring (2007 to 2015) measured survivorship, growth, and condition of 2419 colonies. Survivorship was initially high but generally decreased after two years. Survivorship among projects based on colony counts ranged from 4% to 89% for seven cohorts monitored at least five years. Weibull survival models were used to estimate survivorship beyond the duration of the projects and ranged from approximately 0% to over 35% after five years and 0% to 10% after seven years. Growth rate averaged 10 cm/year during the first two years then plateaued in subsequent years. After four years, approximately one-third of surviving colonies were â„ 50 cm in maximum diameter. Projects used three to sixteen different genotypes and significant differences did not occur in survivorship, condition, or growth. Restoration times for three reefs were calculated based on NOAA Recovery Plan (NRP) metrics (colony abundance and size) and the findings from projects reported here. Results support NRP conclusions that reducing stressors is required before significant population growth and recovery will occur. Until then, outplanting protects against local extinction and helps to maintain genetic diversity in the wild
Scale Invariance and Nonlinear Patterns of Human Activity
We investigate if known extrinsic and intrinsic factors fully account for the
complex features observed in recordings of human activity as measured from
forearm motion in subjects undergoing their regular daily routine. We
demonstrate that the apparently random forearm motion possesses previously
unrecognized dynamic patterns characterized by fractal and nonlinear dynamics.
These patterns are unaffected by changes in the average activity level, and
persist when the same subjects undergo time-isolation laboratory experiments
designed to account for the circadian phase and to control the known extrinsic
factors. We attribute these patterns to a novel intrinsic multi-scale dynamic
regulation of human activity.Comment: 4 pages, three figure
Chaos in Turbulence Driven by the Magnetorotational Instability
Chaotic flow is studied in a series of numerical magnetohydrodynamical
simulations that use the shearing box formalism. This mimics important features
of local accretion disk dynamics. The magnetorotational instability gives rise
to flow turbulence, and quantitative chaos parameters, such as the largest
Lyapunov exponent, can be measured. Linear growth rates appear in these
exponents even when the flow is fully turbulent. The extreme sensitivity to
initial conditions associated with chaotic flows has practical implications,
the most important of which is that hundreds of orbital times are needed to
extract a meaningful average for the stress. If the evolution time in a disk is
less than this, the classical formalism will break down.Comment: 6 pages, 8 figures. To be appear in MNRA
