Las representaciones de los profesores de primaria en formación inicial sobre la crisis del agua en cataluña

La presente es el resultado de un proceso de investigación que indagó sobre las representaciones de futuros maestros de primaria sobre las crisis del agua y la valoración en la utilización de juegos de rol en temas medio ambientales. Se trabajó con un grupo de estudiantes de magisterio de la facultad de ciencias de la educación de la UAB, quienes respondieron un cuestionario y participaron en un juego de rol. El cuestionario indagaba en las representaciones que poseen los futuros maestros sobre la crisis del agua y el juego de rol buscaba conocer las fortalezas y debilidades posibles, en función del contexto diseñado. Los resultados obtenidos indican que los estudiantes de magisterio poseen una escasa multicausalidad asociada a la crisis del agua y muestran una importante valoración de los juegos de rol en el tratamiento de temáticas medioambientales

Dark Patterns in the Design of Games

Game designers are typically regarded as advocates for players. However, a game creator’s interests may not align with the players’. We examine some of the ways in which those opposed interests can manifest in a game’s design. In particular, we examine those elements of a game’s design whose purpose can be argued as questionable and perhaps even unethical. Building upon earlier work in design patterns, we call these abstracted elements Dark Game Design Patterns. In this paper, we develop the concept of dark design patterns in games, present examples of such patterns, explore some of the subtleties involved in identifying them, and provide questions that can be asked to help guide in the specification and identification of future Dark Patterns. Our goal is not to criticize creators but rather to contribute to an ongoing discussion regarding the values in games and the role that designers and creators have in this process

A Framework for Games Literacy and Understanding Games

Based on research that studied the challenges and difficulties faced by students taking games studies and game design courses, this paper proposes that while many students enrolled in games education programs are adept at playing games, they are usually neither games literate nor do they have a deep understanding of games. This article provides a framework that can be used to evaluate and assess games literacy. Using Gee’s notion of literacy, I propose that a deep understanding of games involves having the ability to explain, discuss, describe, frame, situate, interpret, and/or position games (1) in the context of human culture (games as a cultural artifacts), (2) in the context of other games, (3) in the context of the technological platform on which they are executed, (4) and by deconstructing them and understanding their components, how they interact, and how they facilitate certain experiences in players. I describe each of these aspects and also discuss two educational lenses that can be used to help contextualize what it means to understand and learn about games as well as support games literacy in students

Electrocatalysis of hydrazine electrooxidation Part II. Adsorbed mixtures of water soluble sulfonated phthalocyanines

En este trabajo se informan las propiedades catalíticas de tetrasulfoftalocianinas de cobalto (CoTSF) y de hierro (Fe-TSF) co-adsorbidas sobre un electrodo de grafito. Los estudios voltamétricos demuestran que estos compuestos se adsorben sobre el electrodo dando cubrimientos similares a aquellos en que sólo se adsorbe un compuesto. Se examinó las propiedades electrocatalitícas de la mezcla de compuestos para la oxidación de hidracina y se encontró que estos catalizadores actúan en forma independiente, a juzgar por las pendientes obtenidas de curvas de Tafel

Sistema Nacional de Educación a Distancia

Distance education has considerable experience in Mexico; however, its development in the higher education level has depended on the support and interest of each institution, with no national policies. This results in major problems that restrain its contribution to goals increase of coverage and quality of education in the country.Peer Reviewe

Surface electrochemistry : structured electrode, synthesis, and characterization

From introduction: The aim of this special issue is to show, through recent updated significant examples, how the electrochemical techniques allow the unique characterization of specific properties of micro- and nanostructured materials that offer varied possibilities of uses and the preparation of specific types of ordered materials that take advantage of electrochemical synthetic methods such as structuring nanosized wires and dots, to cite only two examples

Mapping Transition Metal-MN4 Macrocyclic Complex Catalysts Performance for the Critical Reactivity Descriptors

There has been a significant progress towards the development of highly active and stable platinum group metal-free (PGM-free) electrocatalysts for the oxygen reduction reaction (ORR) in polymer electrolyte fuel cells (PEFC), promising a low-cost replacement for Pt group electrocatalysts. However, the success of such developments depends on the implementation of PGM-free electrocatalysts that are not only highly active but importantly, they also exhibit long-term durability under PEFC operating conditions. This manuscript is an overview of the current status of a specific, most advanced class of PGM-free electrocatalysts: transition metal-nitrogen-carbon (M-N-C) ORR catalysts. We present an overview for the understanding of catalysts’ performance descriptors for M-N-C materials
