Transforming High School Teaching and Learning: A District-wide Design

High school improvement is one of the most pressing issues facing American education but little attention has been paid to reform strategies that will improve teaching and learning. Drawing on the expertise of teachers, principals, superintendents, policy makers and researchers, a new paper from the Aspen Institute Program on Education, Transforming High School Teaching and Learning: A District-wide Design by Aspen Senior Fellow Judy Wurtzel, offers both a new framework and concrete suggestions for a new approach to high school improvement across an urban school district. The data on high school student performance and graduation rates make clear that significant increases in student achievement are necessary if all students are to graduate from high school fully prepared for post-secondary education, citizenship, and work. Recent high school reform has focused on organizational aspects of high school, particularly creating a wide variety of smaller schools, smaller learning communities, and alternative learning pathways to meet the needs of young people. However, while smaller schools may create the relationships and conditions that make high quality instruction possible, improved instruction and achievement does not flow directly from them. Given this track record, questions facing the high school reform movement include: -- What will it take to get high school instructional improvement that results in demonstrated increases in student learning? -- What supports do high school teachers need to be successful in improving instruction and from where will they get them? -- What changes affecting the professional role, knowledge, and skills of teachers are needed if reforms are to be successful? Though the ideas represented in the paper are not new -- some school districts and states have implemented some of elements described -- what is useful is the attempt to lay out a fairly comprehensive picture of high school instructional reform and to push the conversation about high school instructional improvement into some new territory. First, the paper builds on work done in many urban districts at the K- 8 level to create systems of "managed instruction," that is, deliberate efforts to align common curriculum and instructional materials, formative and benchmark assessments, extensive professional development, and instructional leaders who support a shared set of instructional practices. Second, the paper suggests how these approaches can be developed and implemented in ways that are both consistent with and reinforcing of a robust vision of teacher professionalism. Third, the paper recognizes the urgency of attracting and retaining a teacher workforce that embraces this new job description for high school teachers and can effect improvements in student learning. Finally, it is useful to note that this paper focuses primarily on the district role in improving high school instruction. This is because it seems increasingly clear that school districts are a key unit for instructional improvement. However, much of what is described here could be initiated or supported by states, by consortia of districts, or by networks of managed schools within or across districts

Fusion of 6^{6}Li with 159^{159}Tb} at near barrier energies

Complete and incomplete fusion cross sections for $^{6}$Li+$^{159}$Tb have been measured at energies around the Coulomb barrier by the $\gamma$-ray method. The measurements show that the complete fusion cross sections at above-barrier energies are suppressed by $\sim$34% compared to the coupled channels calculations. A comparison of the complete fusion cross sections at above-barrier energies with the existing data of $^{11,10}$B+$^{159}$Tb and $^{7}$Li+$^{159}$Tb shows that the extent of suppression is correlated with the $\alpha$-separation energies of the projectiles. It has been argued that the Dy isotopes produced in the reaction $^{6}$Li+$^{159}$Tb, at below-barrier energies are primarily due to the $d$-transfer to unbound states of $^{159}$Tb, while both transfer and incomplete fusion processes contribute at above-barrier energies.Comment: Phys.

Refugees, trauma and adversity-activated development

The nature of the refugee phenomenon is examined and the position of mental health professionals is located in relation to it. The various uses of the word 'trauma' are explored and its application to the refugee context is examined. It is proposed that refugees' response to adversity is not limited to being traumatized but includes resilience and Adversity-Activated Development (AAD). Particular emphasis is given to the distinction between resilience and AAD. The usefulness of the 'Trauma Grid' in the therapeutic process with refugees is also discussed. The Trauma Grid avoids global impressions and enables a more comprehensive and systematic way of identifying the individual refugee's functioning in the context of different levels, i.e. individual, family, community and society/culture. Finally, I discuss implications for therapeutic work with refugees

Themes, iteration and recoverability in action research

This paper develops three concepts important to the practice of action research recoverability, research themes, and iteration by highlighting their applicability beyond single action research studies. The concepts are discussed against a program of action research, undertaken by a multidisciplinary research team, with a research focus on local, sector and national evels. This contrasts with the more usual pattern of action research in single situations. Action research is criticized on the grounds that it lacks generalizability and external validity from one-off studies. Goodness criteria have been derived to address these and other criticisms. The recoverability criterion, less strong than the repeatability of experimentation, is central to these. A second concept, that of research themes, links the recoverability criterion and iteration in action research. Iteration within and between projects and the notion of critical mass, of doing work in more than one setting, address the limitations of single setting studies

Physical Infrastructures and Attractiveness of Private Capital in Sub-Saharan African (SSA) Countries

Physical infrastructures are a set of interconnected structural elements whose function is to participate in attracting capital flows in order for the economy to function efficiently. They transfer capital flows that are able to ensure growth and stability. They also constitute a major challenge for growth and development. We have attempted in this paper to study the influence of physical infrastructures and financial development on foreign direct investments (FDIs) in the context of Sub-Saharan African (SSA) countries by combining two theoretical approaches (the Paradox of Lucas and the external-internal factors), and by integrating the correlation between the components of capital flows. Our regressions show the importance of non-linear effects in the explanation of the determinants of private capital. This analysis also emphasizes the more important role physical infrastructures play in attracting FDIs despite perverse effects

Evaluation of the microstructural, electronic and optoelectronic properties of ƴ-CuCl thin films and their fabrication on Si substrates

Cuprous chloride is a direct wide bandgap (Eg = ~ 3.4 eV) semiconductor with a large excitonic binding energy (~ 190 meV). In this study, CuCl has been deposited by the vacuum evaporation method on a variety of substrates (amorphous silica glass, indium tin oxide (ITO) coated on glass and Silicon (100)) substrates, encapsulated and characterized as a potential material for optoelectronic applications. Some of the samples were also oxygen plasma treated for durations of 1, 2 and 3 minutes, respectively. Room temperature x-ray diffraction (XRD) measurements show that CuCl grows preferentially in a (111) orientation irrespective of the underlying substrate. Microstructural properties of the films gave nearly the same values for untreated CuCl films deposited on glass, ITO and Si substrates (particle size, L = 9.6 nm ± 1 nm). On the other hand, the microstructural properties of the plasma treated films vary as a function of plasma treatment duration. At 10 K, the photoluminescence (PL) spectrum of the untreated CuCl/Si films using 244 nm excitation reveals four peaks: the Z₃ free exciton occurring at 3.203 ± 0.003 eV, the I₁ impurity bound exciton located at 3.181 ± 0.003 eV, the M free biexciton occurring at 3.160 ± 0.003 eV and N₁ impurity bound to bi-exciton located at 3.135 ± 0.003 eV. However, the 20 K PL spectra of the untreated CuCl films deposited on all three substrates (using a 325 nm excitation) revealed only the Z₃ free exciton, the I₁ impurity bound exciton and the N₁ impurity bound biexciton at 3.204 eV, 3.18 eV and 3.152 eV, respectively, irrespective of the underlying substrate. The room temperature PL spectra of the films were dominated by the Z₃ free exciton. The measured band gap increased as the temperature increases, which is opposite to most conventional semiconductors. This anomalous effect is believed to be related to electron-phonon renormalization or coupling of the electronic structure of CuCl. On the other hand the PL spectra of the O₂ plasma immersed film were all mainly dominated by the free Z₃ free exciton only. In addition, at low temperatures a broad band ascribed to an oxygen related emission process is observed at ~ 3 eV in all the plasma treated samples. The band gap of the O₂ plasma immersed films follow the anomalous temperature dependency in a similar manner to the untreated films; however the plasma treated films were less sensitive to temperature. Both steady state DC and AC impedance spectroscopy experiments suggested that the untreated CuCl is a mixed ionic-electronic semiconductor material. Room temperature steady state DC measurements using reversible electrodes (Cu) gave an Ohmic response while using irreversible electrodes (Au) gave an exponential I–V behaviour, both in conformance with Wagner’s defect chemistry analysis of a mixed ionicelectronic material. An electronic conductivity of the order of 2.3 × 10-7 S/cm was deduced to be in coexistence with Cu⁺ ionic conductivity using irreversible electrodes (Au), while a total conductivity of the order of 6.5 × 10-7 S/cm was obtained using reversible electrodes (Cu) at room temperature. The Arrhenius plot of the electrical characteristics of the untreated films reveal two distinct regimes corresponding to electronic conduction below ~ 270 K and a Cu⁺ extrinsic ionic conduction mechanism ix above that temperature. Due to the fact that at low temperatures, the thermal energy is inadequate for maintaining considerable ionic motion, it follows that the mode of conduction at lower temperatures is ascribed to electronic processes. On the other hand, the Arrhenius plot of the plasma treated films showed a single regime throughout most of the temperature range. This is interpreted to be an electronically dominant conduction mechanism. The large increase in the conductivity of the treated CuCl films (over 100 fold) is ascribed to effect of oxygen introducing an acceptor state in CuCl films. This is due to the fact that oxygen dissolves in cuprous halides on substitutional anionic sites. Cathodic deposition of Cu metal via electrolytic decomposition was observed when a steady state voltage greater than 5 V was applied to both the untreated and the plasma treated films. This poses a great challenge in utilizing this material to fabricate optoelectronic devices under the influence of steady state source. The untreated films were successfully encapsulated using organic polysilsesquioxane (PSSQ) and cyclo olefin copolymer (COC) dielectrics. However, both encapsulants failed to prevent the O2 plasma immersed films from oxidising, and this will also represent a future challenge for this technology
