"A newly unearthed journal from 1966 shows the coal industry, like the oil industry, was long aware of the threat of climate change. "Exxon knew." Thanks to the work of activists and journalists, those two words have rocked the politics of climate change in recent years, as investigations revealed the extent to which giants like Exxon Mobil and Shell were aware of the danger of rising greenhouse gas emissions even as they undermined the work of scientists. But the coal industry knew, too - as early as 1966, a newly unearthed journal shows."

"It seems only fitting to explore the role of questions in education by asking questions about the process of doing so. I propose that we start with the customary way of framing this topic and then proceed to questions that are deeper and potentially more subversive of traditional schooling. 1. WHICH QUESTIONS? To begin, let's consider what we might ask our students. The least interesting questions are those with straightforward factual answers. That's why a number of writers have encouraged the use of questions described variously as "true" (Wolf, 1987), "essential" (Simon, 2002), "generative" (Perkins, 1992; Perrone, 1998), "guiding" (Traver, 1998), or "fertile" (Harpaz & Lefstein, 2000). What the best of these share is that they're open-ended. Sometimes, in fact, no definitive right answer can be found at all. And even when there is one - or at least when there is reason to prefer some responses to others - the answer isn't obvious and can't be summarized in a sentence. Why is it so hard to find a cure for cancer? Do numbers ever end? Why do people lie? Why did we invade Vietnam? Grappling with meaty questions like these (which were among those generated by a class in Plainview, NY) is a real project . . . literally. A question-based approach to teaching tends to shade into learning that is problem- (Delisle, 1997) and project-based (Kilpatrick, 1918; Blumenfeld et al., 1991; Wolk, 1998). Intellectual proficiency is strengthened as students figure out how to do justice to a rich question. As they investigate and come to understand important ideas more fully, new questions arise along with better ways of asking them, and the learning spirals upwards. Guiding students through this process is not a technique that can be stapled onto our existing pedagogy, nor is it something that teachers can be trained to master during an in-service day. What's required is a continual focus on creating a classroom that is about thinking rather

"Our smartphones enable-and encourage-constant connection to information, entertainment, and each other. They put the world at our fingertips, and rarely leave our sides. Although these devices have immense potential to improve welfare, their persistent presence may come at a cognitive cost. In this research, we test the "brain drain" hypothesis that the mere presence of one's own smartphone may occupy limited-capacity cognitive resources, thereby leaving fewer resources available for other tasks and undercutting cognitive performance. Results from two experiments indicate that even when people are successful at maintaining sustained attention-as when avoiding the temptation to check their phones-the mere presence of these devices reduces available cognitive capacity. Moreover, these cognitive costs are highest for those highest in smartphone dependence. We conclude by discussing the practical implications of this smartphone-induced brain drain for consumer decision-making and consumer welfare."

"Estas rúbricas permiten evaluar y también guiar el diseño y aplicación en clase de diferentes tareas, actividades y proyectos de aula. Alumnos y profesores pueden utilizarlas para desarrollar nuevos modelos de aprendizaje y evaluación en el aula: aprendizajes activos, coevaluación, heteroevaluación… Las rúbricas del ProyectoEDIA son recursos educativos abiertos que cada profesor y grupo de alumnos puede adaptar a sus necesidades y situación.

"Juego de tronos es una excusa para hablar de cómo aceptamos la historia oficial o la que promueve una figura de autoridad. El tema no es nuevo, pero no está agotado. Cada día, una institución pública o un medio de comunicación o un partido político tergiversa hechos propios y ajenos. Cada día, hay personas corrientes que difunden las mentiras por fanatismo o por pereza o por creer que promueve la verdad. La excusa para hablar de esto está en la representación de teatro a la que asiste Arya Stark en la sexta temporada de la serie HBO. ..."
