The loads applied on a linear structural element generate internal forces in the cross sections which, in turn, result in stresses along the element. The nature, extent and shape of stress distributions are required parameters to compute the strength of structural elements or machinery components in order to its analysis or design. In this work, it is presented a virtual laboratory which allows to obtain different stress distributions in an isostatic beam, prismatic or cylindrical, subjected to axial forces, shear forces and bending moments. The virtual laboratory permits a great interactivity, allowing the simulation of various real situations in which the user can modify the magnitude and direction of acting loads, and also the boundary conditions of the beam. The ultimate goal of this paper is to present a tool aimed to support the learning and teaching of subjects related to Elasticy and Strength of Materials that are found in bachelor university degrees.

En este trabajo se efectua una comparacion entre los resultados obtenidos en experimentos de laboratorio y aquellos calculados mediante una simulacion numerica del movimiento de aguas someras en un canal abierto, considerando las perdidas de energia que tienen lugar a su paso por un estrechamiento localizado. El modelo matematico que simula dicho fenomeno fisico se rige mediante un sistema de ecuaciones en derivadas parciales cuya solucion proporciona el calado (profundidad del agua) y el caudal por unidad de ancho, el cual esta relacionado con la velocidad del agua. Dicho movimiento, esta controlado basicamente por la fuerza de la gravedad siendo fundamental la relacion entre esta y las fuerzas inerciales. En el presente estudio se han tenido tambien en cuenta las perdidas de energia originadas por la friccion del agua con los contornos asi como las perdidas locales por obstaculos o cambios de ancho. Para obtener las soluciones de dicho modelo se ha usado un esquema numerico basado en el metodo de volumenes finitos de alta resolucion. Se han efectuado dos tipos de ensayos en un canal de laboratorio. Los del primer tipo representan una transicion en regimen lento, aguas arriba y aguas abajo de un estrechamiento en el canal. Los del segundo tipo representan un regimen lento aguas arriba, un estrechamiento que funciona como control (cambio de regimen) y un regimen rapido aguas abajo. La comparativa numerico-experimental demuestra la importancia de modelizar adecuadamente los distintos fenomenos fisicos que intervienen en el proceso, asi como la correcta imposicion de las condiciones de contorno del problema.

El estudio del movimiento de los cohetes se ha hecho servir durante decadas para estimular a los alumnos en el estudio de la Fisica. Este sistema presenta un indudable interes para introducir conceptos como: propiedades de los gases, leyes de Newton, intercambio entre diferentes tipos de energia y su conservacion o mecanica de fluidos. Nuestro trabajo ha consistido en construir y lanzar estos cohetes en diferentes niveles educativos y en cada uno de estos hemos introducido la parte de la Fisica que mas se adecuaba a los conocimientos de los alumnos. El objetivo de la experiencia didactica es lanzar el cohete lo mas lejos posible y prever la distancia que recorrera, mediante la utilizacion de las leyes de Newton y la mecanica de fluidos. Tras la experimentacion demostramos ser capaces de controlar los parametros que mejoran el funcionamiento de nuestro cohete, tales como el factor de llenado, el volumen y la masa de la botella vacia, densidad del liquido, angulo de lanzamiento, la presion de aire previa al lanzamiento. Ademas, es una experiencia divertida que se puede acoplar a todos los niveles educativos en primaria, secundaria y bachillerato.

We conducted an investigation into certain methodologies described by Finkel in his book “Teaching with your mouth shut” This research consists of an assessment carried out by students from I.E.S. Bovalar in Castellon through a survey. The research aims to prove whether there is a relationship between those methodologies that students consider more participatory, and those which they would like their teachers to use, in other words, if students prefer to use teaching methods which get them more involved, and where they are the center of the teaching-learning process. Following a stadistical analysis using SPSS, we can conclude that there is a direct relationship between those methodologies which students considered more participatory, and those which they would like their teachers to put into practice. Finally, we ascertained the importance of expanding the use of such estrategies to make learning meaningful and for students to improve the acquisition of basic skills.

El proyecto Quick Natura pretende acercar a las personas que habitan o visitan espacios urbanos de la ciudad de Valencia al entorno vegetal que les rodea, de una manera rapida y amena. La iniciativa se basa en el uso de las nuevas tecnologias para conectar el mundo fisico con el virtual mediante la colocacion de codigos QR ( Quick Response code , “codigo de respuesta rapida”) en diferentes especies vegetales de jardines, parques y espacios urbanos y periurbanos. Cualquier usuario podra escanear con un Smartphone u otro dispositivo movil el codigo QR ubicado en las plantas etiquetadas, permitiendo el acceso inmediato a una capa de informacion amena y de facil comprension sobre ese ejemplar. El metodo permite asociar los codigos QR a la pagina web www.uv.es/quicknatura en el cual cada planta esta alojada en un espacio virtual donde los usuarios podran ver: informacion sobre la especie a traves de preguntas y curiosidades, su ubicacion actual, la ubicacion de otros codigos QR cercanos y una serie de rutas disenadas para diferentes jardines de la ciudad de Valencia. El proyecto permite un uso tanto particular como tutelado, con un guia acompanante que pueda complementar la informacion obtenida a traves de Quick Natura.

The Scientific and Technological department of the Adult School Merce Rodoreda, to improve the quality of the formative service offered, has developed a model of a teaching-learning process: the Science and Technology Museum. This model includes a Service Learning orientation that extends the benefits of this proposal beyond the limits of the classroom. For the course 2016/17 it have been designed new activities that improve this orientation. The designed model uses the Project Based Learning as its main method and the “Internal Practices” as its organizational model. This model of teaching-learning process has allowed the Scientific and Technological Department to be placed as a leader in the improvement of the educational quality and the introduction of competences in the center.

This paper presents an introduction about how to model a flow through a porous medium with Computational Fluid Dynamics (CFD). To this end, a case study is proposed by simulating an air current produced by the fan of an air assisted sprayer through a porous medium (vegetation). The work is aimed at adjusting the porosity resistance to the air ow using experimental data. The adjustment assesses three scenarios: one, considering only equal inertial losses between different porous bodies, two, considering both inertial losses and viscous losses and, three, considering only different inertial losses between different porous bodies. Finally, velocities obtained in each simulation are compared with experimental data. The proposed methodology highlights the importance of employing suitable parameters when configuring CFD models.

This article presents a review of research made in the field of mathematics education on the use of video games in the classroom. These investigations have focused on four areas: impact in academic performance focused on mathematical contents, specific mathematical contents learning, videogame design elements for mathematical learning and relation bet-ween videogames and problem solving. Finally, we propose two research new approaches that have not been explored so far, like the use of commercial videogames for mathematical activities or the use of simulation games as environment to promote mathematical modeling.
