Responsive Math Teaching Model

The Responsive Math Teaching (RMT) Model breaks high-quality math teaching down into six core components: Plan: Select or adapt an appropriate task, identify the mathematical goal(s), and anticipate possible solution paths and challenges. Launch: Set up the task so that students understand the problem and can access the important mathematics. Facilitate productive struggle: Support students to engage in authentic problem solving. Discuss learner thinking: Facilitate the sharing of student strategies and reasoning and engage students in making sense of each other’s thinking. Return to mathematical goal: Guide students to make explicit connections between strategies and solutions and the key mathematical ideas. Reflect: Reflect on pedagogical and learning goals to determine next steps

The Responsive Math Teaching Project\u27s (RMT) Planning and Coaching Protocol is an 18-page booklet that includes the RMT Instructional Model as well as a planning and coaching guide for each phase of the RTM instructional cycle. These guides provide questions and facilitation moves to support educators in the planning, implementing, coaching, and/or reflecting on an RMT lesson

A Model for Developing Sustainable Math Instructional Leadership

The Responsive Math Teaching project has been developing and refining a model for the development of mathematics instructional leadership in a network of 13 urban under-resourced elementary schools. The project is a research-practice partnership with Learning Network 2 in the School District of Philadelphia, a city where more than 80% of students live below federal poverty levels in a state with some of the largest gaps in the country between wealthy and poor districts. The RMT project is built around five core components: Developing a shared understanding of high-quality math instruction Ongoing professional development Building a school culture of instructional improvement Leadership development for sustainability Ongoing research for continual improvement This report summarizes the core elements of this model for developing sustainable math instructional leadership for systemic change at the district level

Identification of novel stress-responsive biomarkers from gene expression datasets in tomato roots

Published by CSIRO Publishing. This is the Author Accepted Manuscript. This article may be used for personal use only.Abiotic stresses such as heat, drought or salinity have been widely studied individually. Nevertheless, in the nature and in the field, plants and crops are commonly exposed to a different combination of stresses, which often result in a synergistic response mediated by the activation of several molecular pathways that cannot be inferred from the response to each individual stress. By screening microarray data obtained from different plant species and under different stresses, we identified several conserved stress-responsive genes whose expression was differentially regulated in tomato (Solanum lycopersicum L.) roots in response to one or several stresses. We validated 10 of these genes as reliable biomarkers whose expression levels are related to different signalling pathways involved in adaptive stress responses. In addition, the genes identified in this work could be used as general salt-stress biomarkers to rapidly evaluate the response of salt-tolerant cultivars and wild species for which sufficient genetic information is not yet available

South Carolina residents' knowledge of, perceptions of, and opinions on wildfires and controlled burning

A marketing plan for the Freshwater Fisheries Section of the South Carolina Department of Natural Resources

The purpose of this marketing plan is to provide the Freshwater Fisheries Section of the South Carolina Department of Natural Resources strategic market direction for the next ten years. The core historical mission of the Section has been managing South Carolina’s sport fishery resources and providing recreational fishing opportunities for South Carolina’s freshwater anglers. This marketing plan examines whether this core mission is still relevant in 2003 and, if not, specific directions, opportunities and challenges that will face the Section as it considers alternative opportunities in aligning itself with the needs and desires of South Carolina residents, South Carolina freshwater anglers, South Carolina youth, and the demographic trends taking place within the Palmetto State

Strengthening responsive and reciprocal relationships in a whānau tangata centre: A summary

Although the kindergarten teaching team members were excited at being a part of the parent support and development initiative, they were also aware that they would face challenges that would affect their practice. Their commitment to ensuring effective teaching and learning at Taitoko Kindergarten led them to seek evidence-based teaching practices, inside the vision of the parent support and development initiative. Their involvement with this TLRI research project has helped to provide this. Through action research, the research team has addressed the teachers’ questions associated with (a) the strengthening of relationships (how this has been done so far, and how might it be furthered); (b) changes in practice (what is possible, what appears to be effective); (c) diversity (how a range of “funds of knowledge” (González, Moll, & Amanti, 2005) can be shared and included in curriculum); and (d) documentation (how this can engage families and learners)

Identification of functional cis-regulatory elements by sequential enrichment from a randomized synthetic DNA library

BACKGROUND: The identification of endogenous cis-regulatory DNA elements (CREs) responsive to endogenous and environmental cues is important for studying gene regulation and for biotechnological applications but is labor and time intensive. Alternatively, by taking a synthetic biology approach small specific DNA binding sites tailored to the needs of the scientist can be generated and rapidly identified. RESULTS: Here we report a novel approach to identify stimulus-responsive synthetic CREs (SynCREs) from an unbiased random synthetic element (SynE) library. Functional SynCREs were isolated by screening the SynE libray for elements mediating transcriptional activity in plant protoplasts. Responsive elements were chromatin immunoprecipitated by targeting the active Ser-5 phosphorylated RNA polymerase II CTD (Pol II ChIP). Using sequential enrichment, deep sequencing and a bioinformatics pipeline, candidate responsive SynCREs were identified within a pool of constitutively active DNA elements and further validated. These included bonafide biotic/abiotic stress-responsive motifs along with novel SynCREs. We tested several SynCREs in Arabidopsis and confirmed their response to biotic stimuli. CONCLUSIONS: Successful isolation of synthetic stress-responsive elements from our screen illustrates the power of the described methodology. This approach can be applied to any transfectable eukaryotic system since it exploits a universal feature of the eukaryotic Pol II

Design and Preliminary Testing of Demand-Responsive Transverse Rumble Strips

Transverse rumble strips are common practice to alert drivers by engaging their auditory and tactile senses in addition to visual senses by traffic signals. However, continuous exposure to noise and vibration by transverse rumble strips often results in diminished effectiveness and erratic behaviors, leading to additional safety challenges. In response, demand-responsive transverse rumble strips were developed as traffic safety countermeasures that reduce unnecessary noise and vibration associated with transverse rumble strips by incorporating active control of the rumble strips. Rather than staying static, demand-responsive transverse rumble strips are activated based on the presence of pedestrians, at predesignated times, or in response to abrupt changes in traffic flow. To evaluate the effectiveness of demand-responsive transverse rumble strips, the research team assessed noise and vibration data, both inside the vehicles and on the roadside, for various types of vehicles traveling at different speeds. The test data indicate that demand-responsive transverse rumble strips produced noticeable in-vehicle noise and vibration that could alert drivers to downstream events. Furthermore, demand-responsive transverse rumble strips generated sufficient noise to alert roadside pedestrians to vehicle presence but at low enough level to be considered as acceptable for a residential neighborhood use. Accordingly, demand-responsive transverse rumble strips could address the challenges that static transverse rumble strips face, by providing a design with relatively limited noise while enhancing safety
