Exploring the material mediation of dialogic space : A qualitative analysis of professional learning in initial teacher education based on reflective…
2019
This study addresses the crucial relationship between theory and practice as a key feature of professional learning in initial teacher education. The context for the study is an EU-funded intensive programme drawing on different dimensions of insideness and outsideness and artsbased pedagogies in response to the diversity of education today. The data for the study comes from self-selected pages from preservice teacher participants’ reflective sketchbooks. As a methodological approach that unifies the sensuous and cognitive this study suggests that reflective sketchbooks document the dialogic encounters of students whilst also providing a material space that can itself become a form of dialo…

Transformative Authorship Through Critical Dialogue : Concepts, Theory, and Practice
2021
This conceptual article deals with components and concepts of transformative learning, emphasizing the organization-level perspective on critical reflection. The discussion leans on the concept of transformative authorship and it is argued that it enables authoring processes through which professionals can recognize and recreate their routinized work practices. The aim of the research is to explore how professional experiences are integrated with reflexive, theoretical knowledge through critical dialogue. The authoring process of transformative authorship is illustrated with two complementary case studies from postgraduate health care education. In both cases, the learning tasks were desig…

Supporting student teachers’ reflection through assessment : The case of reflective podcasts
2023
Reflection is a key learning objective of teacher education, yet little is known about the ways in which it could be supported through assessment. In this case study (N = 14), we examine the potential of a novel assessment task—reflective podcasting—in supporting first-year student teachers’ reflection. We analyzed student group podcasts and corresponding student reflections and found that the task engendered reflection. Three theory-driven dimensions were constructed to emphasize the unique nature of podcasts for student reflection: experientiality, authenticity, and communality. We encourage factoring these dimensions into assessment designs that seek to foster student reflection. peerRev…
Digital signal processing applied to noisy acoustic data.
2007
Frequently we deal with analog data from noisy acoustic measurements which need a preprocessing prior to the extraction of the information embedded. Data deterioration may be due to several reasons, for example: data recording on obsolete and technological poor support; bad signal conditioning (poor signal-to-noise ratio, non linearity and/or timevariance of the system under test). Sometimes information to be extracted from data is not conventional so it needs a dedicated processing. In this paper a novel audio data processing method from the autors experience in ancient open-air theatres research is shown.
ESR study of thianthrenium radical cation within acid zeolites
1997
Abstract Thianthrene (E ox = 1.47 V vs NHE) has been adsorbed into a series of zeolites beta (s) and ZSM-5 in the NH 4 + or H + forms, having different particle size and Si/Al ratio. The resulting population of generated thianthrenium radical cation was determined by a combination of diffuse reflectance and ESR spectroscopies. From the results obtained it can be concluded: i) the process takes predominantly place in the interior of the voids (XPS measurements and lack of influence of the particle size); ii) ZSM-5 is more efficient than zeolite s; iii) no strong acid sites are required (both NH 4 + and H + forms produced very similar spin concentrations); iv) the zeolite framework acts isola…
The [Fe(etz)6](BF4)2 Spin-Crossover System—Part One: High-Spin ⇌ Low-Spin Transition in Two Lattice Sites
1996
The [Fe(etz),](BF,), spin-cross-over system (etz = 1-ethyl-1 H-tetrazole) crystallizes in space group P1, with the following lattice constants at 298 K: a 10.419(3), b=15.709(1), c = 18.890(2) A = = 71.223(9), =77.986(10), and = 84.62(1)° V = 2862.0(9) A3 and Z = 3. Two nonequivalent lattice sites, one without (site A) and one with (site B) inversion symmetry, are observed. The population of the two sites nA:nB is 2:l. Iron(II) on site A undergoes a thermal low-spin (LS) high-spin (HS) transition with T1/2I, = 105 K. whereas that on site B remains in the high-spin state down to cryogenic temperatures. Application of external pressure of up to 1200 bar between 200 and 60 K does not cause for…
Steering of a Sub-GeV electron beam through planar channeling enhanced by rechanneling
2014
We report the observation of efficient steering of a 855 MeV electron beam at MAMI (MAinzer MIkrotron) facilities by means of planar channeling and volume reflection in a bent silicon crystal. A $30.5\text{ }\text{ }\ensuremath{\mu}\mathrm{m}$ thick plate of (211) oriented Si was bent to cause quasimosaic deformation of the (111) crystallographic planes, which were used for coherent interaction with the electron beam. The experimental results are analogous to those recorded some years ago at energy higher than 100 GeV, which is the only comparable study to date. Monte Carlo simulations demonstrated that rechanneling plays a considerable role in a particle's dynamics and hinders the spoiling…
Educación XX1 : revista de la Facultad de Educación
2019
Aprender a aprender es una de las competencias claves fijadas por la Comisión Europea (CE, 2005 y 2006) para los sistemas educativos de los países miembros. Las últimas investigaciones ponen de relieve la importancia de que los estudiantes universitarios aprendan a aprender, por lo que este estudio se ubica en la universidad. El objetivo es concretar un modelo teórico sobre dicha competencia que permita su operacionalización en los grados universitarios. Para ello se ha realizado una revisión de la literatura sobre el tema. Después de estudiar su fundamentación científica y la normativa reguladora, se analizaron múltiples modelos -especialmente provenientes de la literatura europea- y se pr…
