description: Few studies have been undertaken exploring the basic question of attitudes of student teachers concerning the integration of information technologies and communications (ITC) in school settings. Nevertheless, we recognize that the motivation of the primary players is essential for ensuring the integration of microcomputers into educational settings. The student teachers live in a techno-educational paradox. This paper discusses the results of a research study concerning beliefs of future teachers regarding the educational integration of ITC into school settings. The data revealed that the participants interviewed expressed favorable opinions regarding the presence of technology in today's society and for the future.

description: A novel framework is proposed to extract near-threshold resonant states from finite-volume energy levels of lattice QCD and is applied to elucidate structures of the positive parity $D_s$. The quark model, the quark-pair-creation mechanism and $D^{(*)}K$ interaction are incorporated into the Hamiltonian effective field theory. The bare $1^+$ $c\bar s$ states are almost purely given by the states with heavy-quark spin bases. The physical $D^*_{s0}(2317)$ and $D^*_{s1}(2460)$ are the mixtures of bare $c\bar s$ core and $D^{(*)}K$ component, while the $D^*_{s1}(2536)$ and $D^*_{s2}(2573)$ are almost dominated by bare $c\bar{s}$. Furthermore, our model reproduces the clear level crossing of the $D^*_{s1}(2536)$ with the scattering state at a finite volume.

Year: 2018

description: In most schools, the individual charged with the responsibility for overseeing the general running of the programs and events is the principal. According to Lunenberg (1995), "the principal's job is to help the school achieve a high level of performance through utilization of its human and material resources. More simply, the principal's job is to get things done by working with and through other people" (p. 3). In this sense , he argued, principals are universal and are essential to schools of all types and sizes - wealthy, poor, rural, urban, large, and small. This article argues that the principal's tasks, especially those associated with instructional leadership, in meeting the needs and concerns of ever-changing schools are numerous, complex, and challenging. In this argument, the principal's instructional leadership roles, the major constraints in the ro le of the principal as an instructional leader, and the strategies for alleviating the problems are examined.

Publisher: name: Journal of Educational Thought / Revue de la Pensée Educative
Year: 2018

description: This paper introduces the anti-colonial discourse as a guiding framework for forming alliances and partnerships among anti-oppression activists in the academia and the larger society. To this end, it builds upon insights from narratives of "indigeneity" and traditions of anti-racism theory and praxis. Thanks to the spaces created by Marxist, feminist, post-colonialist, and deconstructionist struggles, the anti-colonial discourse seeks to reclaim a new independent space strongly interconnected with and heavily interlocked to those other spaces. This paper illustrates the interconnectivities, similarities, and dissimilarities between this new anti-colonial space and the spaces created by those other rich traditions . Its aim is to envision a common zone of resistance in which the oppressed and marginalized groups are enabled to form alliances in resisting various colonial tendencies.

description: Purpose: The paper introduces a classical model to describe the dynamics of large spin-1/2 ensembles associated with nuclei bound in large molecule structures, commonly referred to as the semi-solid spin pool, and their magnetization transfer (MT) to spins of nuclei in Theory and Methods: Like quantum-mechanical descriptions of spin dynamics and like the original Bloch equations, but unlike existing MT models, the proposed model is based on the algebra of angular momentum in the sense that it explicitly models the rotations induced by radio-frequency (RF) pulses. It generalizes the original Bloch model to non-exponential decays, which are, e.g., observed for semi-solid spin pools. The combination of rotations with non-exponential decays is facilitated by describing the latter as Green's functions, comprised in an integro-differential equation. Results: Our model describes the data of an inversion-recovery magnetization-transfer experiment with varying durations of the inversion pulse substantially better than established models. We made this observation for all measured data, but in particular for pulse durations small than 300$μ$s. Furthermore, we provide a linear approximation of the generalized Bloch model that reduces the simulation time by approximately a factor 15,000, enabling simulation of the spin dynamics caused by a rectangular RF-pulse in roughly 2$μ$s. Conclusion: The proposed theory unifies the original Bloch model, Henkelman's steady-state theory for magnetization transfer, and the commonly assumed rotation induced by hard pulses (i.e., strong and infinitesimally short applications of RF fields) and describes experimental data better than previous models.

In en buiten het onderwijs neemt deaandacht voor hoogbegaafde of anderszins getalenteerde leerlingen toe. Daarbij gaathet tevens om hun onderwijservaringen en de mogelijke onderwijsverbeteringen voordeze leerlingen.In 2003 vroeg het ministerie van OCW verschillende instituten van de Radboud UniversiteitNijmegen (ITS, Centrum voor Begaafdheidsonderzoek (CBO), AfdelingOrthopedagogiek: Leren en Ontwikkeling) een aanvrage voor onderzoek in te dienen.Het onderzoek op het gebied van ‘hoogbegaafdheid in het onderwijs’ zou zich metname dienen te richten op mogelijke succescondities in het onderwijs voor hoogbegaafdeleerlingen. Aanvankelijk stonden twee aspecten daarbij op de voorgrond. Teneerste het uitvoeren van een inventarisatie van internationale interventieonderzoekennaar effecten van speciale onderwijsprogramma’s op hoogbegaafde leerlingen, en tentweede het longitudinaal onderzoeken van de effecten van in Nederland plaatsvindendeonderwijsaanpassingen op hoogbegaafde leerlingen. Aanvullend werd in 2005 nogeen derde onderzoeksdeel toegevoegd, namelijk het uitvoeren van een secundaireanalyse op de cohortgegevens van leerlingen en leerkrachten uit het PRIMAonderzoekin het primair onderwijs.De voorliggende rapportage is het verslag van dit derde onderzoeksdeel.

description: Stress-induced shaping, which deforms thin substrates utilizing stressed surface coatings, has enabled and enhanced a host of applications in past decades. Owing to the touchless fabrication process compatible with modern planar technology, the method has been applied from microscale to macroscale applications such as self-assembled micro-structures and space mirrors. However, the deformations created by existing stress-control schemes are limited to certain classes of geometries (such as sphere, coma and astigmatism) or rely on boundary constraints and hinges because the stress is unary, e.g., equibiaxial stress or uniaxial stress with fixed orientation. Here, we present novel stress tensor mesostructures to spatially control the three required stress tensor components, i.e., two normal stresses and a shear stress, over the surface of thin substrates. Three different mesostructure types have been created, each offering distinct advantages. For demonstration, we patterned these mesostructures on the back sides of silicon wafers for freeform shape generation and correction which are not achievable by conventional methods. Stress tensor mesostructures will unleash the value of fields related to stress-induced bending from microscale to macroscopy, such as thin freeform substrates that will become increasingly important with the rise of wearable and space optics.

description: Sufficient disorder is believed to localize static and periodically-driven interacting chains. With quasiperiodic driving by $D$ incommensurate tones, the fate of this many-body localization (MBL) is unknown. We argue that randomly disordered MBL exists for $D=2$, but not for $D\geq 3$. Specifically, a putative two-tone driven MBL chain is neither destabilized by thermal avalanches seeded by rare thermal regions, nor by the proliferation of long-range many-body resonances. For $D\geq 3$, however, sufficiently large thermal regions have continuous local spectra and slowly thermalize the entire chain. En route, we generalize the eigenstate thermalization hypothesis to the quasiperiodically-driven setting, and verify its predictions numerically. Two-tone driving enables new topological orders with edge signatures; our results suggest that localization protects these orders indefinitely.

description: Two-color spin-noise spectroscopy of interacting electron spins in singly charged semiconductor quantum dots provides information on the inter quantum dot interactions. We investigate the spin cross-correlation function in a quantum dot ensemble using a modified semiclassical approach. Spin-correlation functions are calculated using a Hamilton quaternion approach maintaining local quantum mechanical properties of the spins. This method takes into account the effects of the nuclear-electric quadrupolar interactions, the randomness of the coupling constants, and the electron g factor on the spin-noise power-spectra. We demonstrate that the quantum dot ensemble can be mapped on an effective two-quantum dot problem and discuss how the characteristic length scale of the inter-dot interaction modifies the low-frequency cross-correlation spectrum. We argue that details on the interaction strength distribution can be extracted from the cross-correlation spectrum when applying a longitudinal or a transversal external magnetic field.

description: Accurate and timely estimation of precipitation is critical for issuing hazard warnings (e.g., for flash floods or landslides). Current remotely sensed precipitation products have a few hours of latency, associated with the acquisition and processing of satellite data. By applying a robust nowcasting system to these products, it is (in principle) possible to reduce this latency and improve their applicability, value, and impact. However, the development of such a system is complicated by the chaotic nature of the atmosphere, and the consequent rapid changes that can occur in the structures of precipitation systems In this work, we develop two approaches (hereafter referred to as Nowcasting-Nets) that use Recurrent and Convolutional deep neural network structures to address the challenge of precipitation nowcasting. A total of five models are trained using Global Precipitation Measurement (GPM) Integrated Multi-satellitE Retrievals for GPM (IMERG) precipitation data over the Eastern Contiguous United States (CONUS) and then tested against independent data for the Eastern and Western CONUS. The models were designed to provide forecasts with a lead time of up to 1.5 hours and, by using a feedback loop approach, the ability of the models to extend the forecast time to 4.5 hours was also investigated. Model performance was compared against the Random Forest (RF) and Linear Regression (LR) machine learning methods, and also against a persistence benchmark (BM) that used the most recent observation as the forecast. Independent IMERG observations were used as a reference, and experiments were conducted to examine both overall statistics and case studies involving specific precipitation events. Overall, the forecasts provided by the Nowcasting-Net models are superior, with the Convolutional Nowcasting Network with Residual Head (CNC-R) achieving 25%, 28%, and 46% improvement in the test ...

description: Driving a many-body system out of equilibrium induces phenomena such as the emergence and decay of transient states, which can manifest itself as pattern and domain formation. The understanding of these phenomena expands the scope of established thermodynamics into the out-of-equilibrium domain. Here, we experimentally and theoretically study the out-of-equilibrium dynamics of a bosonic lattice model subjected to a strong DC field, realized as ultracold atoms in a strongly tilted triangular optical lattice. We observe the emergence of pronounced density wave patterns -- which spontaneously break the underlying lattice symmetry -- using a novel single-shot imaging technique with two-dimensional single-site resolution in three-dimensional systems, which also resolves the domain structure. Our study suggests that the short-time dynamics arises from resonant pair tunneling processes within an effective description of the tilted Hubbard model. More broadly, we establish the far out-of-equilibrium regime of lattice models subjected to a strong DC field, as an exemplary and paradigmatic scenario for transient pattern formation.

description: While first-principles calculations with different levels of sophistication predict a topologically trivial $Z_2$ state for bulk bismuth, some photoemission experiments show surface states consistent with the interpretation of bismuth being in a topologically non-trivial $Z_2$ state. We resolve this contradiction between theory and experiment by showing, based on quasiparticle self-consistent $GW$ calculations, that the experimental surface states interpreted as supporting a non-trivial phase are actually consistent with a trivial $Z_2$ invariant. We identify this contradiction as the result of a crosstalk effect arising from the extreme penetration depth of the surface states into the bulk of Bi. A film of Bi can be considered bulk-like only for thicknesses of about 1000 bilayers ($\approx$ 400 nm) and more.

description: Worldwide enormous efforts are directed towards the development of the so-called quantum internet. Turning this long sought-after dream into reality is a great challenge that will require breakthroughs in quantum communication and computing. To establish a global, quantum-secured communication infrastructure, photonic quantum technologies will doubtlessly play a major role, by providing and interfacing essential quantum resources, e.g., flying- and stationary qubits or quantum memories. Over the last decade, significant progress has been made in the engineering of on-demand quantum light sources based on semiconductor quantum dots, which enable the generation of close-to-ideal single- and entangled-photon states, useful for quantum cryptography tasks. This review focuses on implementations of, and building blocks for, quantum communication using quantum-light sources based on epitaxial semiconductor quantum dots. After reviewing the main notions of quantum cryptography (section 1) and introducing the devices used for single-photon and entangled-photon generation (section 2), it provides an overview of experimental implementations of cryptographic protocols using quantum dot based quantum light sources (section 3). Furthermore, recent progress towards quantum-secured communication networks as well as building blocks thereof is summarized (section 4). The article closes with an outlook, discussing future perspectives in the field and identifying the main challenges to be solved.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Whether or not anomalies in the thermal conductivity in insulating cuprates can be attributed to antiferromagnetic order and magnons in a 2D Mott insulator remains an intriguing open question. To shed light on this issue, we investigate the thermal conductivity $κ$ and its relationship with the specific heat $c_v$ in the half-filled 2D single-band Hubbard model, using the numerically exact determinant quantum Monte Carlo algorithm and maximum entropy analytic continuation. At low temperatures where the charge degrees of freedom are gapped-out and $c_v$ exhibits a clear magnon peak, we observe that thermal conductivity $κ$ also tends to form a peak at similar temperatures. Reducing temperature further produces a sharp upturn in $κ$, associated with an increasing mean-free path. We identify this as the high-temperature side of the anomalous peak in insulating cuprates, where the mean-free path eventually is cut-off by other scattering effects, including phonons, disorder, and physical size. Different scattering effects in our model are identified and analyzed in the thermal diffusivity.

description: In 1983 we are drawing close to the end of the ten years which the United Nations designated the Decade for Women. Hal f-way through that decade, in 1980, in Australia, the proportion of women in the population involved in some kind of post-secondary education had equalled the proportion of men. Only a year earlier it was possible to claim that 'Women's studies courses are at present offered at most Australian universities ' .1 In 1982 the University of New South Wales established a course-work postgraduate degree (a Master [sic] of Arts) in Women's Studies. In 1983 the University of Adelaide set up a Research Centre in Women's Studies . And related courses have proliferated at other educational institutions , ranging from the Studies in Sexism course offered at the Australian National Capital's School Without Wall s, through a host of units - Modern Women Writers, Social History of Women, Women and Film, The Family (as a ' small social system') - taught at the New South Wales Institute of Technology, to the Graduate Diploma course in Women's Studies at the State College of Victoria and the Graduate Diploma in Teaching (Women's Studies) taught at South Australia's College of Advanced Education.

description: In several searches for additional Higgs bosons at the LHC, in particular in a CMS search exploring decays to pairs of top quarks, $t \bar t$, and in an ATLAS search studying tau leptons, $τ^+τ^-$, local excesses of about $3\,σ$ standard deviations or above have been observed at a mass scale of approximately $ 400$GeV. We investigate to what extent a possible signal in these channels could be accommodated in the Next-to-Two-Higgs-Doublet Model (N2HDM) or the Next-to Minimal Supersymmetric Standard Model (NMSSM). In a second step we analyze whether such a model could be compatible with both a signal at around $400$GeV and $96$GeV, where the latter possibility is motivated by observed excesses in searches for the $b \bar b$ final state at LEP and the di-photon final state at CMS. The analysis for the N2HDM reveals that the observed excesses at $400GeV$ in the $t \bar t$ and $τ^+τ^-$ channels point towards different regions of the parameter space, while one such excess and an additional Higgs boson at around $96$GeV could simultaneously be accommodated. In the context of the NMSSM an experimental confirmation of a signal in the $t \bar t$ final state would favour the alignment-without-decoupling limit of the model, where the Higgs boson at $125$GeV could be essentially indistinguishable from the Higgs boson of the standard model. In contrast, a signal in the $τ^+τ^-$ channel can only be accommodated outside of this limit, and parts of the investigated parameter space could be probed with Higgs signal-rate measurements at the (HL-)LHC.

description: Everything combined to make 1973 a good year to start Women's Studies at Flinders University. We'd had some success in the anti-Vietnam movement and many of us were fee ling that we could exercise some power in society. The Women's Movement had been around long enough for "progressive men" to pay lip service to it, though few of them thought it had much application to their own lives. The long boom of the sixties had resulted in many sections of the Australian community being relatively well-off. An expansion of the student body was achieved by the abandonment of fees, then the introduction of freely available loans, and finally by payment of student allowances. The range of courses was expanded also, and in this atmosphere of liberality, some educational innovations were possible.

description: We investigate the density and optical responses of a linear triple component fermionic system in both non-interacting and interacting regimes by computing its dynamical polarization function, RPA dielectric function, plasmon mode and long wavelength optical conductivity and compare the results with those of Weyl fermions and three-dimensional free electron gas. Linear triple component fermions are pseudospin-1 generalization of Weyl fermions, consisting of two linearly dispersive bands and a flat band. The presence of flat band brings about notable modifications in the response properties with respect to Weyl fermions such as induction of a new region in the particle-hole continuum, increased static polarization, reduced plasmon gap, shift in absorption edge, enhanced rate of increase in energy absorption with frequency and highly suppressed intercone transitions in the long wavelength limit. The plasmon dispersion follows the usual $ω\sim ω_0+ ω_1 q^2$ nature as observed in other three-dimensional systems.

description: Cette étude a été menée (i) dans le but de  classifier les concepts de la chimie organique selon leur difficulté et (ii) d’identifier les facteurs à la base des difficultés d’apprentissage de ces concepts en chimie organique par les étudiants burundais. Un questionnaire a été distribué à 136 étudiants du département de Biologie-chimie de l’université du Burundi. Les données collectées ont été analysées avec le logiciel SPSS.

Les résultats obtenus montrent que, en fonction de leur moyenne, les cinq premiers concepts jugés difficiles tel que cela a été ordonné par les étudiants interrogés sont la Stéréoisomérie (2,60), la Géométrie des molécules (2,48), l’Hybridation des orbitales (2,26), les Anhydrides (2,24) et l’Energie d'activation (2,15). Les facteurs dont la corrélation est statistiquement significative avec les concepts difficiles sont l’insuffisance des prérequis (rp= 0,412, n= 136 ; p <0,001) et le manque d’occasion d’apprendre en groupes en dehors des cours (rp= -0,177, n = 136 ; p = 0,039). Par contre, les facteurs sexe, niveau d’étude, niveau socioéconomique des parents, connaissances de l’enseignant, le fait d’avoir un syllabus de cours vaste, ancienneté de l’enseignant, effectif des étudiants n’ont pas d’influence sur les difficultés de compréhension des concepts en chimie organique.

Au regard des résultats obtenus, en particulier les variables ayant statistiquement exercé une influence significative sur les difficultés de compréhension des concepts en chimie organique tel qu’exprimé par les étudiants de l’Université du Burundi, l’installation des prérequis en chimie organique s’avère nécessaire au secondaire pour asseoir chez les futurs étudiants des connaissances qui faciliteront leurs apprentissages académiques. L’expérimentation au laboratoire pourrait également faciliter la maîtrise de ces concepts jugés difficiles au secondaire.  De plus, les institutions d’enseignement supérieur devraient dégager un créneau horaire pour permettre aux étudiants de travailler en groupes.

description: Unconventional superconductors have Cooper pairs with lower symmetries than in conventional superconductors. In most unconventional superconductors, the additional symmetry breaking occurs in relation to typical ingredients such as strongly correlated Fermi liquid phases, magnetic fluctuations, or strong spin-orbit coupling in noncentrosymmetric structures. In this article, we show that the time-reversal symmetry breaking in the superconductor LaNiGa$_2$ is enabled by its previously unknown topological electronic band structure. Our single crystal diffraction experiments indicate a nonsymmorphic crystal structure, in contrast to the previously reported symmorphic structure. The nonsymmorphic symmetries transform the $k_z=π/c$ plane of the Brillouin zone boundary into a node-surface. Band-structure calculations reveal that distinct Fermi surfaces become degenerate on the node-surface and form Dirac lines and a Dirac loop at the Fermi level. Two symmetry related Dirac points remain degenerate under spin-orbit coupling. ARPES measurements confirm the calculations and provide evidence for the Fermi surface degeneracies on the node-surface. These unique topological features enable an unconventional superconducting gap in which time-reversal symmetry can be broken in the absence of other typical ingredients. LaNiGa$_2$ is therefore a topological crystalline superconductor that breaks time-reversal symmetry without any overlapping magnetic ordering or fluctuations. Our findings will enable future discoveries of additional topological superconductors.

description: The adoption of Unmanned Aerial Vehicles (UAVs) for public safety applications has skyrocketed in the last years. Leveraging on Physical Random Access Channel (PRACH) preambles, in this paper we pioneer a novel localization technique for UAVs equipped with cellular base stations used in emergency scenarios. We exploit the new concept of Orthogonal Time Frequency Space (OTFS) modulation (tolerant to channel Doppler spread caused by UAVs motion) to build a fully standards-compliant OTFS-modulated PRACH transmission and reception scheme able to perform time-of-arrival (ToA) measurements. First, we analyze such novel ToA ranging technique, both analytically and numerically, to accurately and iteratively derive the distance between localized users and the points traversed by the UAV along its trajectory. Then, we determine the optimal UAV speed as a trade-off between the accuracy of the ranging technique and the power needed by the UAV to reach and keep its speed during emergency operations. Finally, we demonstrate that our solution outperforms standard PRACH-based localization techniques in terms of Root Mean Square Error (RMSE) by about 20% in quasi-static conditions and up to 80% in high-mobility conditions.

description: While periodically-driven phases offer a unique insight into non-equilibrium topology that is richer than its static counterpart, their experimental realization is often hindered by ubiquitous decoherence effects. Recently, we have proposed a decoherence-free approach of realizing these Floquet phases. The central insight is that the reflection matrix, being unitary for a bulk insulator, plays the role of a Floquet time-evolution operator. We have shown that reflection processes off the boundaries of systems supporting higher-order topological phases (HOTPs) simulate non-trivial Floquet phases. So far, this method was shown to work for one-dimensional Floquet topological phases protected by local symmetries. Here, we extend the range of applicability by studying reflection off three-dimensional HOTPs with corner and hinge modes. We show that the reflection processes can simulate both first-order and second-order Floquet phases, protected by a combination of local and spatial symmetries. For every phase, we discuss appropriate topological invariants calculated with the nested scattering matrix method.

Educational Thoughts of Aristotle and Confucius

Publisher: name: Journal of Educational Thought / Revue de la Pensée Educative
Year: 2018

description: This study examines the educational principles and aims of Aristotle and Confucius. Through a descriptive analysis, the research questions of the study are assessed. Both philosophers subscribed to the common educational principles that emphasize ethical education for building individual cultivation, social harmony, and the ideal state. The individual and social aims of education are: (a) to provide the proper method of training the virtuous persons who have ideal characters through self-cultivation, and (b) to build the harmonious community and the good state through development of a gentleman or a nobleman. On the other hand, differences include: Confucius emphasized his ethical and political principles without supporting the metaphysical and epistemological theories, which was unlike Aristotle's approach; he did not use a set of tools like Aristotle's Organ on to justify his ethical and political thought. Finally, the article claims that Confucius generally stressed self cultivation through humanity and ritual, while Aristotle primarily emphasized self-actualization through habit and reason.

description: Neural networks are increasingly used to estimate parameters in quantitative MRI, in particular in magnetic resonance fingerprinting. Their advantages over the gold standard non-linear least square fitting are their superior speed and their immunity to the non-convexity of many fitting problems. We find, however, that in heterogeneous parameter spaces, i.e. in spaces in which the variance of the estimated parameters varies considerably, good performance is hard to achieve and requires arduous tweaking of the loss function, hyper parameters, and the distribution of the training data in parameter space. Here, we address these issues with a theoretically well-founded loss function: the Cramér-Rao bound (CRB) provides a theoretical lower bound for the variance of an unbiased estimator and we propose to normalize the squared error with respective CRB. With this normalization, we balance the contributions of hard-to-estimate and not-so-hard-to-estimate parameters and areas in parameter space, and avoid a dominance of the former in the overall training loss. Further, the CRB-based loss function equals one for a maximally-efficient unbiased estimator, which we consider the ideal estimator. Hence, the proposed CRB-based loss function provides an absolute evaluation metric. We compare a network trained with the CRB-based loss with a network trained with the commonly used means squared error loss and demonstrate the advantages of the former in numerical, phantom, and in vivo experiments.

Identity in the Philosophies of Dewey and Freire: Select Analyses

Year: 2018

description: Identity, even if it has not been separately treated in the educational philosophies of John Dewey and Paulo Freire, remains, nevertheless, an important component of the teaching and writing of the two philosophers. This paper first presents a limited discussion of some theoretical and conceptual points on identity, followed by a general discussion of identity as it has been, either directly or indirectly, located in the educational philosophies of Dewey and Freire. The importance of identity, whether at the community, national, or even international stages, and as an educational and social development construct, is being rendered more fluid , dynamic, and therefore , probably less tangible by such transnational and trans-continental forces of globalization, information technology, and the electronic media. The paper ends with the acknowledgment that, while observations in this short article could only be the beginning of an interesting debate, a vigorous undertaking in reexamining questions and issues of identity (against the backdrop of Dewey an and Freire an philosophies of education) should be appreciated.
