What is the problem? The challenge of providing effective teachers for all children

Publisher: name: American University
Year: 2023

description: Richard Murnane and Jennifer Steele argue that if the United States is to equip its young people with the skills essential in the new economy, high-quality teachers are more important than ever. In recent years, the demand for effective teachers has increased as enrollments have risen, class sizes have fallen, and a large share of the teacher workforce has begun to retire. Women and minorities have more career options than ever before, making it increasingly difficult to attract and retain the many effective teachers who are needed. Moreover, schools are limited in their ability to identify and reward the most effective teachers. Perhaps the most urgent problem facing American education, say Murnane and Steele, is the unequal distribution of high-quality teachers. Poor children and children of color are disproportionately assigned to teachers with the least preparation and the weakest academic backgrounds. Teacher turnover is high in schools that serve large shares of poor or nonwhite students because the work is difficult, and the teachers who undertake it are often the least equipped to succeed. Murnane and Steele point out that in response to these challenges, policymakers have proposed a variety of policy instruments to increase the supply of effective teachers and distribute those teachers more equitably across schools. Such proposals include across-the-board pay increases, more flexible pay structures such as pay-for-performance, and reduced restrictions on who is allowed to teach. Several of these proposals are already being implemented, but their effectiveness remains largely unknown. To measure how well these policies attract effective teachers to the profession and to the schools that need them most, rigorous evaluations are essential. Murnane and Steele also note that policymakers may benefit from looking beyond U.S. borders to understand how teacher labor markets work in other countries. Although policies rooted in one nation's culture cannot be easily and quickly transplanted into another, it is important to understand what challenges other countries face, what policies they are using, and how well those policies are working to enhance teacher quality and improve student achievement.

description: The last two decades have witnessed a vast expansion in the use of education data to improve classroom instruction and raise student achievement. Schools and districts face important challenges in implementing increased data use for instructional improvement. One key challenge is the need for teachers and administrators to have data literacy--the skills to analyze data, and to use a variety of data sources to refine and improve instruction. Data systems and data initiatives have grown at a much faster pace than educator training around data use. This reality justifies the evaluation of a program such as TERC's Using Data, which aims to provide teachers with the needed training. A table and figure are appended. Using school-level random assignment, this study seeks to estimate the causal impact of TERC's Using Data (UD) program on elementary teachers' understanding and use of data to inform mathematics instruction, and on the mathematics achievement of their fourth and fifth grade students. The main questions were: (1) At the end of the first year of the intervention, do fourth and fifth grade students in schools randomly assigned to the UD treatment program show greater levels of math achievement as compared to their counterparts in control schools? (2) After the first year of the intervention, do UD-trained teachers in treatment schools report greater data-use knowledge and skills and more-positive attitudes and beliefs about the value of data to inform instruction as compared to their same-grade counterparts in control schools?; and (3) After the first year of the intervention, do UD-trained teachers in treatment schools reportedly make more use of data or work more frequently with data in a collaborative setting, as compared to their same-grade counterparts in control schools? in comparison to control teachers? A large, urban district in the southeastern U. S. joined the study in March 2011, agreeing to implement the Using Data program. Sixty schools were randomized into the treatment group (30 schools) or the control group (30 schools), with an average of four teacher participants and one data coach from each school taking on the same treatment condition as their school. Our sample includes over 11,000 students and 800 math teachers in the 60 schools. The design was a block-randomized experiment with two levels of treatment--Using Data versus practice as usual. Preliminary analysis of pre/post survey data from teachers suggests that collaborative data use increased in the treatment schools relative to the control schools at statistically significant levels.

description: This paper seeks to synthesize much recent work on the HTSC materials around the latest STM results from Davis and coworkers. The conductance diffuse scattering results in particular are used as point of entry to discuss bosonic modes, both of condensed and uncondensed form. The bosonic mode picture is essential to understanding an ever growing range of observations within the HTSC field. The work is expounded within the context of the negative-U, boson-fermion modelling long advocated by the author. This general approach is presently seeing much theoretical development, into which I have looked to couple many of the experimental advances. While the formal theory is not yet sufficiently detailed to cover adequately all the experimental complexities presented by the real cuprate systems, it is clear that it affords very appreciable support to the line taken. An attempt is made throughout to say why and how it is that these events are tied so very closely to this particular set of materials.

title: Role of Life Strategies in Diatom Biodiversity: A Modelling Approach
Creators: name: Stec, Krzystof Franciszek
Publisher: name: The Open University
Year: 2016

description: A theoretical framework explaining what regulates the number of species and their temporal and spatial patterns is still lacking making plankton diversity a challenging issue in ecology. In this study the nature and relevance of some of the drivers of marine diatoms dynamics and diversity over the seasons have been investigated by coupling experimental and numerical approaches. The main focus was on the life cycle, especially important for marine diatoms and overlooked as a possible driver of diversity. The performed laboratory experiments provided evidence of growth rate decrease occurring independently from resource availability during the sexual phase, which is a mandatory component of most diatom life cycles. The ecological and evolutionary implications of this biological mechanism have been explored with a developed ad hoc numerical model of seasonal plankton dynamics in the mixed layer. The model includes a detailed parametrization of the physical and chemical environments, and a set of phytoplankton species characterized by distinct physiological traits. The validation exercise demonstrated model’s applicability to address questions on plankton seasonal dynamics and diversity patterns. The modelling exercise showed that the coordinated growth rate reduction in diatoms during mating, even in presence of plentiful resources, would affect diversity patterns and functioning of the plankton community even if shared only by a subset of species. In addition, other factors including grazers’ migration and phytoplankton species immigration, as well as the role of the seasonal characteristics of the water column affecting plankton succession and species diversity were also investigated. This suggests that the above factors impact the community structure and its time course. In particular, biological regulation in diatoms, and likely in many other protists, can be remarkably sophisticated and should be considered to improve our understanding of plankton diversity, a question made even more important by the current climate change.

description: The extensive use of social media platforms and overwhelming amounts of imagery data creates unique opportunities for sensing, gathering and sharing information about events. One of its potential applications is to leverage crowdsourced social media images to create a tapestry scene for scene analysis of designated locations and time intervals. The existing attempts however ignore the temporal-semantic relevance and spatio-temporal evolution of the images and direction-oriented scene reconstruction. We propose a novel social-sensor cloud (SocSen) service composition approach to form tapestry scenes for scene analysis. The novelty lies in utilising images and image meta-information to bypass expensive traditional image processing techniques to reconstruct scenes. Metadata, such as geolocation, time and angle of view of an image are modelled as non-functional attributes of a SocSen service. Our major contribution lies on proposing a context and direction-aware spatio-temporal clustering and recommendation approach for selecting a set of temporally and semantically similar services to compose the best available SocSen services. Analytical results based on real datasets are presented to demonstrate the performance of the proposed approach.

description: An increasing number of AGNs exhibit broad, double-peaked Balmer emission lines, which arise from the outer regions of the accretion disk which fuels the AGN. The line profiles vary on timescales of 5--10 years. Our group has monitored a set of 20 double-peaked emitters for the past 8 years (longer for some objects). Here we describe a project to characterize the variability patterns of the double-peaked H alpha line profiles and compare with those of two simple models: a circular disk with a spiral arm and an elliptical disk.

description: Braneworld cosmology supported by a bulk scalar field with an exponential potential is developed. A general class of separable backgrounds for both single and two-brane systems is derived, where the bulk metric components are given by products of world-volume and bulk coordinates and the world-volumes represent any anisotropic and inhomogeneous solution to an effective four-dimensional Brans-Dicke theory of gravity. We deduce a cosmic no hair theorem for all ever expanding, spatially homogeneous Bianchi world-volumes and find that the spatially flat and isotropic inflationary scaling solution represents a late-time attractor when the bulk potential is sufficiently flat. The dependence of this result on the separable nature of the bulk metric is investigated by applying the techniques of Hamilton-Jacobi theory to five-dimensional Einstein gravity. We employ the spatial gradient expansion method to determine the asymptotic form of the bulk metric up to third-order in spatial gradients. It is found that the condition for the separable form of the metric to represent the attractor of the system is precisely the same as that for the four-dimensional world-volume to isotropize. We also derive the fourth-order contribution to the Hamilton-Jacobi generating functional. Finally, we conclude by placing our results within the context of the holographic approach to braneworld cosmology.

description: Sodium atoms and clusters (N<5) on graphite (0001) are studied using density functional theory, pseudopotentials and periodic boundary conditions. A single Na atom is observed to bind at a hollow site 2.45 A above the surface with an adsorption energy of 0.51 eV. The small diffusion barrier of 0.06 eV indicates a flat potential energy surface. Increased Na coverage results in a weak adsorbate-substrate interaction, which is evident in the larger separation from the surface in the cases of Na_3, Na_4, Na_5, and the (2x2) Na overlayer. The binding is weak for Na_2, which has a full valence electron shell. The presence of substrate modifies the structures of Na_3, Na_4, and Na_5 significantly, and both Na_4 and Na_5 are distorted from planarity. The calculated formation energies suggest that clustering of atoms is energetically favorable, and that the open shell clusters (e.g. Na_3 and Na_5) can be more abundant on graphite than in the gas phase. Analysis of the lateral charge density distributions of Na and Na_3 shows a charge transfer of about 0.5 electrons in both cases.

description: This study aims to help address a need for information about efficacious mathematics curriculum and instruction at the high school level. Data from national and international studies, including the National Assessment of Educational Progress (NAEP), show very low mathematics proficiency rates for high school students. Many educators recognize a need to improve mathematics achievement through interventions such as new curriculum materials or instructional approaches, however they lack rigorous evidence on efficacy. By providing such information, this study can help guide educators in selecting the most promising materials. The purpose of the study is to evaluate the efficacy of the Cognitive Tutor Geometry curriculum by Carnegie Learning Inc., using randomized controlled trials.
title: Developing Primary Teachers' Mathematics Subject Knowledge: A Practitioner Research Study that Explores the Developed Nature of Primary Teachers' Subject Knowledge in Mathematics; the Factors Which Influenced its Development and its Interrelationship with and Influence on Changes in Professional Practice, Within the Context a Mathematics Specialist Teacher Programme (MaST)
Creators: name: Morgan, Deborah Catherine
Publisher: name: The Open University
Year: 2016

description: The study is set within the context of the Mathematics Specialist Teacher Programme (MaST) at a University in England. This programme was a two year Masters' level professional development for primary teachers. The research questions explore the nature of the subject knowledge developed by the teachers; the factors which influenced its development and how the developed subject knowledge interacts with and influences classroom practice. A practitioner research approach was adopted, influenced by the concept of phenomenography. Grounded theory was applied to analyse the data in order to develop theory. A mixed methods strategy was used, involving mainly qualitative data with some quantitative data collected through both questionnaires and group interviews. The main findings were that: - The development of teacher subject knowledge is dynamic and continuous and has the potential to develop within the context of practice. - A connected structure applied to the programme design had significant impact on teacher development. - The particular constructs used within the programme acted as vehicles for transference of developed subject knowledge into practice. My recommendations for policy and future research are: - The development of a national framework for primary teacher subject knowledge in mathematics, which outlines the required knowledge and recommendations for development. This would require research, agreement and evaluation. - Further research into effective strategies for the development of teacher subject knowledge in mathematics, including the application of a big ideas framework.

description: local Community-based Rural Tourism (hereafter lCRT) has become for many rural areas a relevant tool to encourage strategies of local development capable. some empirical researches focus on lCTR as a model capable of generating economic and social, and environmental benefits in rural areas (employment, new sources of incomes, rescue of cultural traditions, conservation of natural resources,…), as well as encourage farming activities and foster the organization among people. it has come to regard as an alternative model of sustainable tourism to the dominant model of conventional tourism. Furthermore, the lCRT model has become an important complement activity to family farms. in this paper, the author analyses some cases of lCRT in Costa Rica rural in order to show the role this alternative tourism model plays in the launch of rural development strategies conducted by local population.

description: Purpose: Critical thinking pervades formal educational benchmarks in the United States, including the Common Core State Standards. However, little information is available on how it develops. Hence, the primary purpose of this study was to examine the development of critical thinking in adolescents using a written language-sampling task. We also examined related aspects of development: verbal productivity, syntactic complexity, and metacognitive verb use.Method: The participants included two groups of adolescents, aged 13 and 16 years (n = 40 per group). All testing took place in classrooms at a middle school or high school. Participants read four fables by the Greek storyteller Aesop (circa 620–560 B.C.) and explained in writing why they agreed or disagreed with the moral message of each story. To examine critical thinking, we evaluated their explanations using a unique 0- to 4-point scoring system. We also examined each participant’s transcript for verbal productivity, syntactic complexity, and metacognitive verb use.Results: On the critical thinking task, the 16-year-olds outperformed the 13-year-olds, providing explanations that were more elaborate and detailed. However, there were many individual differences within groups, and even the older group did not consistently perform at the highest level, indicating that critical thinking is a late-developing ability. Age-related gains also occurred on verbal productivity and metacognitive verb use but not on syntactic complexity.Conclusion: Information gleaned from this study demonstrates how critical thinking develops during adolescence but remains incomplete. The study also has implications for assessing critical thinking in adolescents and knowing how to prompt complex language and thought.

description: The present article addresses the fishing activity in the native indian Community in Gamboa-Peru through a spatial analysis of the territory; from the understanding of the local knowledge, the representativeness in both sectors economic, food, and cultural reproduction; it is widely developed by the inhabitants of the region as an integral part of their traditional knoledge. Undoubtedly, the pressure on natural resources is manifested in dissimilar processes of mineral exploitation, animal extraction, and flora, loss of strategic ecosystems as well as the gradual population growth and urban expansion experienced by surrounding cities to indigenous settlement. This context of struggle for the use and land tenure, requires the consideration regarding food sovereignty of indigenous communities, especially in the particularity of cross-border relations in the Triple Amazon frontier where Ticunas develop their ancient arts.

description: We present a database and velocity catalogue towards the region of the Shapley Supercluster based on 18,146 measured velocities for 10,719 galaxies in the approximately 300 square degree area between 12h 43mn 00s < R.A. < 14h 17mn 00s and -23° 30' 00" < Dec < -38° 30' 00". The data catalogue contains velocities from the literature found until 2015. It also includes 5,084 velocities, corresponding to 4,617 galaxies, observed by us at Las Campanas and CTIO observatories and not reported individually until now. Of these, 2,585 correspond to galaxies with no other previously published velocity measurement before 2015. Every galaxy in the velocity database has been identified with a galaxy extracted from the SuperCOSMOS photometric catalogues. We also provide a combined average velocity catalogue for all 10,719 galaxies with measured velocities, adopting the SuperCOSMOS positions as a homogeneous base. A general magnitude cut-off at R2=18.0 mag was adopted (with exceptions only for some of the new reported velocities). In general terms, we confirm the overall structure of the Shapley Supercluster, as found on earlier papers. However, the more extensive velocity data show finer structure, to be discussed in a future publication.

description: During the last decades the use of economic instruments to improve the water demand management has been suggested due to the difficulty of further increase in the supply. in this sense, this paper analyses the potential of water banks as a type of water markets that can provide institutional flexibility in the allocation of water resources among different users. Research has involved an extensive review of the literature, which has allowed the development of a typology of water banks operating worldwide, as well as a critic analysis of the experiences implemented to date, in order to assess the performance of this economic instrument in order to improve water management. this has allowed to evidence that water banks are a useful instrument to minimize the socioeconomic and environmental effects of droughts. However, the Spanish experience regarding water banks has been limited to date, being devoted almost exclusively to improve the environmental status of water bodies. Finally, the analysis performed has allowed to provide suggestions about how to improve the implementation of this instrument in Spain, providing guidelines for the legal reforms required in this sense.

description: Heat alters colour and crystallinity of teeth by destruction of the organic content and inducing hydroxyapatite crystal growth. The colour and crystallite changes can be quantified using spectrophotometric and x-ray diffraction analyses, however these analyses are not commonly used in combination to evaluate burned dental remains. In this study, thirty-nine teeth were incinerated at 300-1000$^\circ$C for 15 and 30 minutes and then measured using a spectrophotometer and an x-ray diffractometer. Response variables used were lightness, L$^\ast$, and chromaticity a$^\ast$ and b$^\ast$ and luminance (whiteness and yellowness) for colour, and crystal size for crystallinity. Statistical analysis to determine the attribution of these variables revealed yellowness and crystal size were significantly affected by temperature ($p < 0.05$), whilst duration of heat-exposure showed no significant effect. This study suggests the inclusion of both spectrophotometric and x-ray diffraction in investigating thermal-heated teeth is useful to accurately estimate the temperature teeth are exposed to.

description: This study aims to help address a need for information about efficacious mathematics curriculum and instruction at the high school level. Data from national and international studies, including the National Assessment of Educational Progress (NAEP), show very low mathematics proficiency rates for high school students. Many educators recognize a need to improve mathematics achievement through interventions such as new curriculum materials or instructional approaches, however they lack rigorous evidence on efficacy. By providing such information, this study can help guide educators in selecting the most promising materials. The purpose of the study is to evaluate the efficacy of the Cognitive Tutor Geometry curriculum by Carnegie Learning Inc., using randomized controlled trials.

Implementing “insider” ethnography : lessons from the Public Conversations about HIV/AIDS project in rural South Africa

description: We describe the conceptualization and implementation of a research methodology in which “insider” community members work with “outsider” investigators as participant observers to document everyday conversations taking place in public settings in their communities. Our study took place in a resource-poor area of rural South Africa and focused on HIV/AIDS, yet we aim here to provide a road map for those interested in implementing this approach in other contexts for various empirical ends. Because this approach is unusual, we highlight considerations in selecting a team of ethnographers, describe the training process, and offer ways to ensure the data collected are trustworthy and confidential. We describe the advantages and limitations of utilizing “insider ethnography” in contexts where being indigenous to the study site provides access to perspectives that cannot be obtained through other methods. Finally, we examine how mutuality and the positionality of the research team affect data collection and quality.

description: The objective of this work is to promote a change in the assessment of cultural landscapes of agricultural terraces on islands where tourism development and the neglect of agriculture have led to changes (territorial, socio-economic, environmental and cultural) to their marginalization, which endanger their conservation. To do so, documents of the instruments for management of protected areas, land and heritage management are analyzed besides the scientific literature, in which various aspects of such cultural landscapes are addressed. The results show the institutional and scientific marginalization to which these landscapes have undergone in the Canaries, which contrasts with the international scene.

description: The continual push to directly image exoplanets at lower masses and closer separations orbiting around bright stars remains limited by both quasi-static and residual adaptive optics (AO) aberration. In previous papers we have proposed a modification of the self-coherent camera (SCC) design to address both of these limitations, called the Fast Atmospheric SCC Technique (FAST). In this paper we introduce an additional modification to the FAST focal plane mask design, including the existing Tip/tilt and Gaussian components and adding a charge four Vortex (TGV) component. In addition to boosting SCC fringe signal-to-noise ratio (S/N) as in our previous design, we show that the FAST TGV mask is also optimized to reach high contrast at separations closer to the star. In this paper we use numerical simulations to consider the performance improvement on correcting quasi-static aberration using this new mask compared to the previously proposed Tip/tilt+Gaussian mask. Using active deformable mirror control to generate a calibrated half dark hole improves contrast by a factor of about 200 at 2 - 5 $λ/D$ and up to a factor of 10 at 5 - 20 $λ/D$. The new methodology presented in this paper, now simultaneously considering both contrast and fringe S/N, opens the door to a new ideology of coronagraph design, where the coronagraph is now considered in duality as both a diffraction attenuator and a wavefront sensor.

The evolution of the high energy tail in the quiescent spectrum of the soft X-ray transient Aql X-1

description: A moderate level of variability has been detected in the quiescent luminosity of several neutron star soft X-ray transients. Spectral variability was first revealed by Chandra observations of Aql X-1 in the four months that followed the 2000 X-ray outburst. By adopting the canonical model for quiescent spectrum of soft X-ray transients, i.e. an absorbed neutron star atmosphere model plus a power law tail, Rutledge et al. (2002a) concluded that the observed spectral variations can be ascribed to temperature variations of the neutron star atmosphere. These results can hardly be reconciled with the neutron star cooling that is expected to take place in between outbursts (after deep crustal heating in the accretion phase). Here we reanalyse the Chandra spectra of Aql X-1, together with a long BeppoSAX observation in the same period, and propose a different interpretation of the spectral variability: that this is due to correlated variations of the power law component and the column density (>5, a part of which might be intrinsic to the source), while the temperature and flux of the neutron star atmospheric component remained unchanged. This lends support to the idea that the power law component arises from emission at the shock between a radio pulsar wind and inflowing matter from the companion star.
