Este trabajo tiene por objetivo utilizar una plataforma robótica educativa como herramienta de refuerzo en la adquisición de las competencias relacionadas con el pensamiento computacional y matemático en alumnos de Educación Primaria. Se entiende el pensamiento computacional como un conjunto de habilidades, entre las que se incluye el pensamiento algorítmico, mediante las que cualquier persona es capaz de resolver problemas. Los contenidos a desarrollar se abordarán empleando la estrategia pedagógica STEM, combinando las disciplinas de Ciencia, Tecnología, Ingeniería y Matemáticas en el proceso de aprendizaje. En este sentido, se propone la adaptación del entorno tecnológico para poder emplearlo en edades tempranas. Concretamente, se proponen varios enunciados relacionados con la resolución de problemas matemáticos enmarcados en el nivel de Educación Primaria y se va a realizar una adaptación de los bloques de programación necesarios para solucionarlos. Para ello, se crean diferentes bloques personalizados de programación, en los que el docente puede incluir comportamientos más complejos que serán transparentes para el alumno. Por consiguiente, el alumno podrá resolver un abanico mayor de problemas, liminando la posibilidad de que el entorno de programación ofrezca limitaciones que se traduzcan en un aumento de la complejidad.
The study and modelling of EMC are becoming more critical than ever due to the ubiquitous presence of electronic circuits in all aspects of our lives. Specifically, it is crucial to extend these studies to the new frequencies that, in a few years, will be a reality in modern telecommunications systems, such as 5G and its derived technologies. A specific critical field where the proper EMI shielding has been ensured to avoid EMC problems is the electric autonomous vehicles (EAVs). The huge number of electronics systems in new vehicles will dramatically extend the demands on the EMI shielding solutions used to attenuate the radiated emissions that could affect circuits in the vehicle. Metals or metal alloys are the most common EMI shielding materials since they demonstrate adequate shielding capacity against EMI. However, polymers have become up-and-coming materials for EMI shielding with the characteristics of lightweight, flexibility, cost-effective, easy processing, and resistance to corrosion. Consequently, it is necessary to develop EMI shielding materials based on polymers, plastic materials, and fiber composites that ensure compliance with the different standards that regulate 5G and the proper operation of possible systems susceptible to the intentional and unintended signals generated by this new technology. This contribution focuses on characterizing different composite structures performance based on fibers combined with conductive materials in terms of shielding effectiveness, covering the 5G sub-6 GHz frequency range.
How to design communications systems and its foundations depends on various factors such as the accessibility to learning resources, the academic environment and the audience itself. This article reports how the introduction of learning methodologies based on project based learning (PBL), practical devices and asynchronous working has modified the perception of the students about their learning aptitudes. The combination of traditional and offline sessions, with the PBL methodology to perform practical communications systems demonstrations based on professional SDR devices by group of students is presented and analysed in this article. The quantified outcome of their academic involvement due to this innovation is evaluated. The indicators shows that the overall dimensions of student learning of communications systems were improved compared with previous sessions based on simulated, non-groupal and magistral lectures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
