Competencia Científica y Resolución de Problemas de Física

2020

Resumen Impulsar y desarrollar la competencia científica entre los estudiantes que cursan materias como la Física, es un objetivo contemplado actualmente de forma explícita en la mayoría de los currículos escolares y es compartido por muchos expertos en Didáctica de las Ciencias Experimentales. Sin embargo, cuando se trata este tema con el profesorado de ciencias, suele hacerse ignorando los contenidos concretos de la materia a enseñar, con lo cual, los profesores difícilmente pueden trasladar a sus clases aquello que les ha sido expuesto en términos demasiado generales o abstractos. En nuestra opinión, si realmente se quiere impulsar y desarrollar la competencia científica, ello ha de hace…

Influence of a Thiolate Chemical Layer on GaAs (100) Biofunctionalization: An Original Approach Coupling Atomic Force Microscopy and Mass Spectrometr…

2013

International audience; Widely used in microelectronics and optoelectronics; Gallium Arsenide (GaAs) is a III-V crystal with several interesting properties for microsystem and biosensor applications. Among these; its piezoelectric properties and the ability to directly biofunctionalize the bare surface, offer an opportunity to combine a highly sensitive transducer with a specific bio-interface; which are the two essential parts of a biosensor. To optimize the biorecognition part; it is necessary to control protein coverage and the binding affinity of the protein layer on the GaAs surface. In this paper; we investigate the potential of a specific chemical interface composed of thiolate molec…

Girls4STEM: Gender Diversity in STEM for a Sustainable Future

2020

Science, Technology, Engineering, and Mathematics (STEM) are key disciplines towards tackling the challenges related to the Sustainable Development Goals. However, evidence shows that women are enrolling in these disciplines in a smaller percentage than men, especially in Engineering related fields. As stated by the United Nations Women section, increasing the number of women studying and working in STEM fields is fundamental towards achieving better solutions to the global challenges, since the potential for innovation is larger. In this paper, we present the Girls4STEM project, which started in 2019 at the Escola T&egrave

Diseño de un sistema de apoyo a la regulación social del aprendizaje en los xMOOC

2019

Esta investigación tiene como objetivo estudiar los procesos de regulación del aprendizaje, atendiendo tanto a su dimensión individual como social, en entornos de xMOOC. En concreto, se propone analizar cómo los procesos de autorregulación, corregulación y regulación social compartida pueden apoyarse y promoverse en este tipo de contextos abiertos y masivos para conseguir un aprendizaje más profundo. Para ello, se aplica un modelo de investigación basada en el diseño que permite intervenir directamente en la práctica pedagógica, a través de un proceso cíclico de cuatro etapas: diseño, intervención, evaluación y reflexión y rediseño de un sistema de apoyo a la regulación del aprendizaje en u…

Academic performance in terms of the applied assessment system

2012

This paper examines the academic performance depending on the evaluation and rating system used in the university. The sample under study consists of 30 subjects -taught by 35 professors to 2192 students from 7 different degrees at 14 universities of all Spain-. The results confirm that continuous assessment is the one that best results not only in terms of rate of return and success rate but also in terms of grades.

Design and Characterization of Effective Ag, Pt and AgPt Nanoparticles to H2O2 Electrosensing from Scrapped Printed Electrodes

2019

The use of disposable screen-printed electrodes (SPEs) has extraordinarily grown in the last years. In this paper, conductive inks from scrapped SPEs were removed by acid leaching, providing high value feedstocks suitable for the electrochemical deposition of Ag, Pt and Ag core-Pt shell-like bimetallic (AgPt) nanoparticles, onto screen-printed carbon electrodes (ML@SPCEs, M = Ag, Pt or AgPt, L = metal nanoparticles from leaching solutions). ML@SPCEs were characterized by scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectroscopy. The results were compared to those obtained when metal nanoparticles were synthesised using standard solutions of metal salts (MS@…

A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens

2017

The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…
