New wine into old skins: the enactment of literacy policy in Singapore

To better comprehend how educational reforms and classroom practice interconnect, we need to understand the epistemic environments created for learning, as well as the pedagogical activities and the modes of classroom discourse related to these activities. This article examines how a particular innovation in English literacy, Strategies for English Language Learning and Reading (STELLAR), has been implemented in Singapore. Outlining the broader curriculum initiatives, current literacy policy landscape and pedagogical effect of classroom discourse, we look at how English language teachers in grades 1 and 2 interpret the STELLAR curriculum. Situated within the larger international zeal of educational reform, Singapore presents a rich case for the study of policy–pedagogy initiatives, literacy instruction and cultural values. Adding to the existing policy enactment research, this investigation provides an opportunity to probe both the prospects and limitations of policy implementation associated with centralised educational structures, examination-oriented systems and societal cultural frameworks.

SUPPORTING LEARNING FOR NAVAJO STUDENTS THROUGH ETHNOMATHEMATICS

The purpose of this research was to address how culturally informed ethnomathematical methods of teaching can be utilized to support the learning of Navajo students in mathematics. The study was conducted over the course of four years on the Navajo Reservations at Tohatchi Middle School in Tohatchi New Mexico. The students involved in the study were all in 8th grade and were enrolled either in Algebra 1 or a Response to Intervention, RTI, class. The data collected came in the form of a student survey, student observation and student assessment. The teacher written survey, a math textbook word problem, and two original math textbook problems along with their rewritten version were the sources of these three studies. The first year of the study consisted of a math attitude survey and how Navajo students perceived math as a subject of interest. The students answered four questions pertaining to their thoughts about mathematics. The students’ responses were positive according to their written answers. The second year of the study involved the observation of how students worked through a math word problem as a group. This method tested how the students culturally interacted in order to solve a math problem. Their questions and reasoning to solve the problem were shared with peers and the teacher. The teacher supported the students in understanding and solving the problem by asking questions that kept the students focused on the goal of solving the problem. The students worked collaboratively and openly in order to complete the activity. During the iv study, the teacher was more able to notice the students’ deficiencies individually or as a group, therefore was able to support them in a more specific manner. The last study was conducted over a period of two different years. This study was used to determine how textbook bias in the form of its sentence structure or word choice affects the performance of students who are not culturally familiar with one or both. It was found that the students performed better and took less time on the rewritten problem than on the original problem. The data suggests that focusing on the culture, language and education of Navajo students can affect how the students learn and understand math.

Consequences of Kondo exchange on quantum spins

When individual quantum spins are placed in close proximity to conducting substrates, the localized spin is coupled to the nearby itinerant conduction electrons via Kondo exchange. In the strong coupling limit this can result in the Kondo effect — the formation of a correlated, many body singlet state — and a resulting renormalization of the density of states near the Fermi energy. However, even when Kondo screening does not occur, Kondo exchange can give rise to a wide variety of other phenomena. In addition to the well known renormalization of the g factor and the finite spin decoherence and relaxation times, Kondo exchange has recently been found to give rise to a newly discovered effect: the renormalization of the single ion magnetic anisotropy. Here we put these apparently different phenomena on equal footing by treating the effect of Kondo exchange perturbatively. In this formalism, the central quantity is ρJ, the product of the density of states at the Fermi energy ρ and the Kondo exchange constant J. We show that perturbation theory correctly describes the experimentally observed exchange induced shifts of the single spin excitation energies, demonstrating that Kondo exchange can be used to tune the effective magnetic anisotropy of a single spin.

Imaging of spin waves in atomically designed nanomagnets

The spin dynamics of all ferromagnetic materials are governed by two types of collective phenomenon: spin waves and domain walls. The fundamental processes underlying these collective modes, such as exchange interactions and magnetic anisotropy, all originate at the atomic scale. However, conventional probing techniques based on neutron1 and photon scattering2 provide high resolution in reciprocal space, and thereby poor spatial resolution. Here we present direct imaging of standing spin waves in individual chains of ferromagnetically coupled S = 2 Fe atoms, assembled one by one on a Cu2N surface using a scanning tunnelling microscope. We are able to map the spin dynamics of these designer nanomagnets with atomic resolution in two complementary ways. First, atom-to-atom variations of the amplitude of the quantized spin-wave excitations are probed using inelastic electron tunnelling spectroscopy. Second, we observe slow stochastic switching between two opposite magnetization states3, 4, whose rate varies strongly depending on the location of the tip along the chain. Our observations, combined with model calculations, reveal that switches of the chain are initiated by a spin-wave excited state that has its antinodes at the edges of the chain, followed by a domain wall shifting through the chain from one end to the other. This approach opens the way towards atomic-scale imaging of other types of spin excitation, such as spinon pairs and fractional end-states5, 6, in engineered spin chains.

Com Sona l’ESO: un exemple del tractament de la llengua i la literatura des de l’àrea de música dins del concepte d’ensenyament integral

Com Sona l'ESO és un projecte en què s’integren música i dansa, literatura, llengua i educació amb una doble finalitat: traure fora de les quatre parets de l’aula el treball que es fa dia a dia amb l’alumnat i oferir-los l’oportunitat d’actuar en directe damunt d’un escenari. En aquest article es descriu el treball dins i fora de l’aula que culmina en aquest espectacle durant 16 edicions està recorrent diferents poblacions i centres del territori lingüístic i es posa en valor el caràcter multidisciplinari, la implicació social, el protagonisme de l’alumnat i l’èxit d’un treball que esdevé plenament aprenentatge significatiu.

The development of color categories in two languages: a longitudinal study

This study unites investigations into the linguistic relativity of color categories with research on children's category acquisition. Naming, comprehension, and memory for colors were tracked in 2 populations over a 3-year period. Children from a seminomadic equatorial African culture, whose language contains 5 color terms, were compared with a group of English children. Despite differences in visual environment, language, and education, they showed similar patterns of term acquisition. Both groups acquired color vocabulary slowly and with great individual variation. Those knowing no color terms made recognition errors based on perceptual distance, and the influence of naming on memory increased with age. An initial perceptually driven color continuum appears to be progressively organized into sets appropriate to each culture and language. PsycINFO Database Record (c) 2009 APA, all rights reserved

Crianças e investigação: aspectos teórico-metodológicos e cuidados éticos nas produções dos grupos de pesquisa da UFRN

The concepts of childhood are part of a cultural construction and vary throughout history politically, economically and socially. Nouns such as "childhood" and "child" did not exist as sense of unity in periods prior to modernity, reinforcing their historical character as concepts that have been socially constructed as profess the Historical Social Psychology, theoretical perspective which will support this research. The sociology of childhood distinguishes the terms and changes the approach toward the adult researcher approach with respect to children, aiming to give voice to the child. When it comes to defining the role of children in research, the researcher must take into consideration several relevant criteria such as age, gender, time, listening to the adults close to the children, the level of language and education and which children that will be heard in a group. It is from this discussion, considering the importance of children's participation in the research that are established the purpose of this work, namely, to analyze the theoretical and methodological aspects and ethical guidelines considered in the research process with children, by researchers at the UFRN, presenting as specific objectives: analyze and discuss, from research reports, the adopted ethical procedures and methods used in research with children. Set the goal, it was made a search of the UFRN Research Groups in SIGAA in order to select those which investigate children for participating in our survey. Among the centers of UFRN, we selected the Health Sciences Centre - CCSA, the Humanities Center, Letters and Arts - CCHLA, the Biosciences Center - CB and the Health Sciences Center - CCS, a total of 64 finalized reports to be analyzed. And here it is the observation that the foolish reports were not analyzed for ethical reasons as the guiding of this dissertation is the coordinator of the research group mentioned. In this study, we chose the documentary analysis of the finalized reports from UFRN research projects teachers / researchers as procedure to set up the corpus of the research. Data analysis was performed from the qualitative analysis in the following categories were established: the concept of childhood, concept of child, age of the subjects, the research context, theoretical and methodological care adopted and ethical care. It is hoped that this study will contribute with reflections on the ethical and theoretical and methodological care on research with children. The research showed how some of the results: significant number of reports excluded by repetition, most reports did not bring any closing remarks, no different procedures for children, with rare exceptions, the ethical issue was not mentioned in 50% of reports.

English Language Education at University: Trends and Challenges in Teaching and Learning Academic Discourse in the UK

This chapter discusses English Language Education at university and highlights a number of trends and their associated challenges in teaching and learning academic discourse. Academic discourse refers to the ways in which language is used by participants in academia. It encompasses written discourse, from article and book publishing, PhD theses to course assignments; spoken discourse, from study groups, tutorials, conference presentations to inaugural lectures; and more recently, computer-mediated discourse, from asynchronous text-based conferencing to academic blogs. The role of English language educators in preparing students and academics for successful participation in these academic events, or the academy, in English is not to be underestimated. Academic communication is not only vital to an individual’s success at university, but to the maintenance and creation of academic communities and to scientific progress itself (Hyland, 2009). This chapter presents an overview of academic discourse and discusses recent issues which have an impact on teaching and learning English at university and discusses their associated challenges: first, the increasing internationalisation of universities. Second, the emergence of a mobile academe in its broadest sense, in which students and academics move across traditional geopolitical, institutional and disciplinary boundaries, is discussed. Third, the growth of UK transnational higher education is examined as a trend which sees academics and students vicariously or otherwise involved in English language teaching and learning. Fourth, the chapter delves into the rapid and ongoing development in technology assisted and online learning. While responding to trends can be difficult, they can also inspire ingenuity. Furthermore, such trends and challenges will not emerge in the same manner in different contexts. The discussion in this chapter is illustrated with examples from a UK context but the implications of the trends and challenges are such that they reach beyond borders.

Language ideologies and Schooled Education in Rural Tanzania : The Case of Karagwe

In this article I argue that language policies for education have effects on pupils’ educational possibilities. With the case of Karagwe district in Tanzania I have found that the case of “Swahili only” in primary school education favours the small minority of the children that live in a context where Swahili is used. This leads to inequality in pupils’ chances in education and to a low level of achievement of academic content in schools. This also promote the developing and use of safety strategies among teachers and pupils that hide failure and prevent pupils’ learning.
