Līdzdalības didaktiskās stratēģijas kā dažādības pedagoģiskais risinājums vidusskolēniem STEM kompetenču iegūšanas procesā
2017
Mūsdienu pasaulē, kur tehnoloģijas nemitīgi turpina attīstīties, skolotājiem ir nepieciešams pielietot šo iespaidīgo rīku, lai rosinātu ieinteresētību skolēnos un motivētu viņus. Viens no Meksikas Vidējās izglītības sistēmas reformas mērķiem ir attīstīt vispārējas un disciplināras kompetences Fizika IV priekšmetā starp dažādiem vidusskolas skolēniem. Lai sasniegtu šo mērķi, tiek izmantotas tādas didaktiskās stratēģijas kā prezentācijas klasē un savstarpēja sadarbība starp skolēniem, kas tiek papildinātas ar Robert Marzano Dimensiju teoriju, konstruktīvisma fokusu un padziļinātu mācību apguvi. Pielietojot šīs stratēģijas, tiek demonstrēts, ka motivēti skolēni strādā labāk, apgūst kompetences…
The new version of the pictorial scale of Perceived Movement Skill Competence in Spanish children: Evidence of validity and reliability. [La nueva ve…
2019
The purpose of this study was to i) examine reliability and construct validity of the pictorial scale of Perceived Movement Skill Competence (PMSC) aligned to the third version of the Test of Gross Motor Development (TGMD-3) in a sample of Spanish children; and to ii) analyse the validity of the PMSC and children’s perceived motor competence (MC) according to gender. A convenience sample of 361 children (55.7% boys) between 4 and 11 years-old participated. The pictorial scale of PMSC (19 items) was administered (a random subsample repeated the PMSC twice). Test-retest reliability using Intraclass Correlation Coefficients and construct validity using a Bayesian Structural Equation Modeling a…
Shift-Invariant Canonical Polyadic Decomposition of Complex-Valued Multi-Subject fMRI Data with a Phase Sparsity Constraint
2020
Canonical polyadic decomposition (CPD) of multi-subject complex-valued fMRI data can be used to provide spatially and temporally shared components among groups with both magnitude and phase information. However, the CPD model is not well formulated due to the large subject variability in the spatial and temporal modalities, as well as the high noise level in complex-valued fMRI data. Considering that the shift-invariant CPD can model temporal variability across subjects, we propose to further impose a phase sparsity constraint on the shared spatial maps to denoise the complex-valued components and to model the inter-subject spatial variability as well. More precisely, subject-specific time …
Evaluación por rúbricas de la Composición Escrita en 2º ciclo de Educación Primaria
2015
Evaluación por rúbricas de la Composición Escrita en 2º ciclo de Educación Primaria. Resumen El objetivo de este estudio de tesis doctoral es elaborar y validar un sistema de rúbricas como instrumento de evaluación e información de los procesos docentes, permitiendo la medición de aprendizajes complejos; en concreto, la habilidad para componer textos escritos, cuando aún no está consolidada esta subcompetencia; es decir, durante su proceso de adquisición. El nivel educativo seleccionado para la obtención de las muestras de producción escrita es 2º Ciclo de Educación Primaria, con alumnos entre los 8 y 10 años. Y la cuestión es ¿evalúa la rúbrica construida lo que intenta medir? Para ello, s…
Improving Image Quality in a multi-plane Compton Telescope for Hadron Therapy Monitoring
2023
Esta disertación explora diferentes técnicas para mejorar la calidad de las imágenes obtenidas con cámaras Compton. Tal mejora es una de las necesidades principales que obstaculizan la aplicación de cámaras Compton como herramientas para la verificación en tiempo real de terapia hadrónica, a través de la obtención de imágenes de distribuciones espaciales de emisión rápida de rayos gamma emitidos como subproductos de las interacciones de estos hadrones en el paciente. Esta aplicación presenta importantes dificultades, pues requiere medir rayos gamma de energías relativamente altas emitidos en un rango de energías amplio y junto a otras partículas no deseadas. Además, la cámara Compton debe s…
Journalistic construction of Science through the Mass Media: Towards a taxonomy of the broadcast of Scientific knowledge
2011
Scientific facts are broadcasted through the media are part of the cultural heri-tage of this Society. In Spain, the presence of scientific content in audiovisual media is scarce. By the way, on press, are more elaborate, and the tendency is to give more coverage to scientific news, for reasons we’ll argüe throughout this paper. It’s important fact to assess the construction process of science journalism media and the process of recontextualization of speech, once stories will be moved from the scientific press to the media. In this article we propose a taxonomy of forms of broadcast scientific facts through the media. After analyzing television news stories for a decade, the classification…
Representações sociais, sens pratique, poder simbólico e o processo de construção do ser docente
2019
A partir de las elaboraciones teóricas de los fundadores del campo de investigación de las representaciones sociales, se pretende avanzar en la construcción de un diálogo entre esta teoría y la praxis social de Pierre Bourdieu, centrándose en la relación entre las representaciones sociales, la praxis sensorial (como manifestación del hábito) y el poder simbólico, dimensión ausente en el modelo moscoviciano. La base empírica a partir de la cual se desarrollan las reflexiones presentes en este artículo se apoya en investigaciones realizadas sobre el proceso de construcción del ser docente, en la realidad de algunas ciudades del nordeste brasileño. En este sentido, se destaca lo que se cree qu…
Development of Neural Network Prediction Models for the Energy Producibility of a Parabolic Dish: A Comparison with the Analytical Approach
2022
Solar energy is one of the most widely exploited renewable/sustainable resources for electricity generation, with photovoltaic and concentrating solar power technologies at the forefront of research. This study focuses on the development of a neural network prediction model aimed at assessing the energy producibility of dish–Stirling systems, testing the methodology and offering a useful tool to support the design and sizing phases of the system at different installation sites. Employing the open-source platform TensorFlow, two different classes of feedforward neural networks were developed and validated (multilayer perceptron and radial basis function). The absolute novelty of this approac…
Energy and Environmental Assessment of a Hybrid Dish-Stirling Concentrating Solar Power Plant
2022
Although the 2019 global pandemic slowed the growing trend of CO2 concentrations in the atmosphere, it has since resumed its rise, prompting world leaders to accelerate the generation of electricity from renewable sources. The study presented in this paper is focused on the evaluation of the energy and environmental benefits corresponding to the hypothesis of hybridizing a dish-Stirling plant installed on the university campus of Palermo (Italy). These analyses were carried out by means of dynamic simulations based on an accurate energy model validated with the experimental data collected during the measurement campaign that occurred during the period of operation of the reference plant. As…
