Strengthening the Clinical Orientation of Teacher Preparation Programs
Educators and policymakers across the United States recognize a growing urgency to improve the nation's systems of teacher preparation. Ensuring that teachers stay and thrive in the profession depends largely on having system-wide policies and practices in place that address teacher shortages, promote equity and excellence, and cultivate expertise, diversity, and more.The California State University (CSU) system partnered with the S.D. Bechtel, Jr. Foundation to launch the New Generation of Educators Initiative (NGEI), in an effort to transform the nature and quality of teacher preparation at both individual CSU campuses and across the CSU system as a whole. To answer the question, "What does it take to transform teacher education?" WestEd and SRI International conducted an evaluation to examine and share learnings about the CSU-led effort to implement large-scale clinically oriented teacher preparation reform.As part of a series of new evaluation reports that explore key transformational elements of effective teacher preparation programs, this paper identifies key levers to put high-quality clinical experience - that is, the opportunity to practice the work of teaching in classrooms - at the center of teacher preparation. Findings in this report explore the following high-leverage strategies to strengthen the clinical orientation of teacher preparation programs:Lever 1: Identify prioritized skillsLever 2: Select or create a rubric to assess candidate proficiency with prioritized skillsLever 3: Integrate and expand opportunities to practice prioritized skillsLever 4: Re-conceptualize clinical roles, selection, and supportLever 5: Define and implement processes to provide formative feedback to candidates on prioritized skill
emerging perspectives for flood risk assessment and management
Flood estimation and flood management have traditionally been the domain of
hydrologists, water resources engineers and statisticians, and disciplinary
approaches abound. Dominant views have been shaped; one example is the
catchment perspective: floods are formed and influenced by the interaction of
local, catchment-specific characteristics, such as meteorology, topography and
geology. These traditional views have been beneficial, but they have a narrow
framing. In this paper we contrast traditional views with broader perspectives
that are emerging from an improved understanding of the climatic context of
floods. We come to the following conclusions: (1) extending the traditional
system boundaries (local catchment, recent decades, hydrological/hydraulic
processes) opens up exciting possibilities for better understanding and
improved tools for flood risk assessment and management. (2) Statistical
approaches in flood estimation need to be complemented by the search for the
causal mechanisms and dominant processes in the atmosphere, catchment and
river system that leave their fingerprints on flood characteristics. (3)
Natural climate variability leads to time-varying flood characteristics, and
this variation may be partially quantifiable and predictable, with the
perspective of dynamic, climate-informed flood risk management. (4) Efforts
are needed to fully account for factors that contribute to changes in all
three risk components (hazard, exposure, vulnerability) and to better
understand the interactions between society and floods. (5) Given the global
scale and societal importance, we call for the organization of an
international multidisciplinary collaboration and data-sharing initiative to
further understand the links between climate and flooding and to advance flood

Challenges of operational river forecasting
Skillful and timely streamflow forecasts are critically important to water managers and emergency protection services. To provide these forecasts, hydrologists must predict the behavior of complex coupled human–natural systems using incomplete and uncertain information and imperfect models. Moreover, operational predictions often integrate anecdotal information and unmodeled factors. Forecasting agencies face four key challenges: 1) making the most of available data, 2) making accurate predictions using models, 3) turning hydrometeorological forecasts into effective warnings, and 4) administering an operational service. Each challenge presents a variety of research opportunities, including the development of automated quality-control algorithms for the myriad of data used in operational streamflow forecasts, data assimilation, and ensemble forecasting techniques that allow for forecaster input, methods for using human-generated weather forecasts quantitatively, and quantification of human interference in the hydrologic cycle. Furthermore, much can be done to improve the communication of probabilistic forecasts and to design a forecasting paradigm that effectively combines increasingly sophisticated forecasting technology with subjective forecaster expertise. These areas are described in detail to share a real-world perspective and focus for ongoing research endeavors
Synoptic dendroclimatology: a process-based approach for linking tree-ring information to atmospheric circulation over the Pacific and western North America [abstract]
EXTRACT (SEE PDF FOR FULL ABSTRACT):
Synoptic dendroclimatology uses dated tree rings to study and reconstruct climate from the viewpoint of the climate's weather components and their relationship to atmospheric circulation. This approach defines a connection between large-scale circulation and ring-width variation at local sites using correlation fields, composite maps, indexing, and other circulation-based methodologies
