"This book is a collection of homework problems for use in an introductory physics course. It is a work in progress, currently complete through mechanics and electromagnetism. There is a complete set of ancillary materials, including solutions and an online answer checker. If you're an instructor, you can use these problems as a plug-in replacement for the ones in a commercial textbook, thus insulating yourself from common hassles associated with using the problems from a commercial text. For example, you can change books without having to redo all your problem sets, or you can tell your students that they can use any edition of a particular text."

"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 core ecological problem is not climate change. It is overshoot, of which global warming is a symptom. Overshoot is a systemic issue. Over the past century-and-a-half, enormous amounts of cheap energy from fossil fuels enabled the rapid growth of resource extraction, manufacturing, and consumption; and these in turn led to population increase, pollution, and loss of natural habitat and hence biodiversity. The human system expanded dramatically, overshooting Earth's long-term carrying capacity for humans while upsetting the ecological systems we depend on for our survival. Until we understand and address this systemic imbalance, symptomatic treatment (doing what we can to reverse pollution dilemmas like climate change, trying to save threatened species, and hoping to feed a burgeoning population with genetically modified crops) will constitute an endlessly frustrating round of stopgap measures that are ultimately destined to fail."

"El aprendizaje basado en la resolución de problemas o Problem-Based Learning (PBL) es una metodología que sitúa a los alumnos en el centro del aprendizaje y les dota de responsabilidad para resolver con autonomía determinados retos. Diez pasos para trabajar con la resolución de problemas 1. Planificación. 2. Organización de los grupos. 3. Presentación del problema y aclaración de términos. 4. Definición del problema. 5. Lluvia de ideas. 6. Planteamiento de respuestas e hipótesis. 7. Formulación de los objetivos de aprendizaje. 8. Investigación. 9. Síntesis y presentación. 10. Evaluación y autoevaluación."

"there is no live teacher engagement... Currently, just 10 percent of MOOC registrants complete their courses. Where Will MOOCs Be Just Two Years From Now? Within the next two years, MOOCs will quickly evolve from lacking teacher engagement to having a lot of teacher engagement. Right now, it's essentially a model where computers are teaching students. This model is simply not sustainable in the long run without live student-teacher engagement. Teachers are the key that unlocks learning in these courses. They help students resolve issues and problems. Will the biggest change in online education moving forward be putting live teachers at the center of the MOOC (not just on video)? We will know the answer very soon."

Las primeras respuestas tardaron apenas unos minutos en aparecer. En la versión estadounidense del debate predominaron las respuestas que tenían que ver con conceptos como creatividad y emprendimiento, pero también hubo algunas centradas en la necesidad de más habilidades y de desarrollar la capacidad de resolver problemas. "I wish someone told me that learning skills and getting real-world experience is infinitely more valuable than good grades. The world is looking for problem-solvers who help them push forward, not people who can regurgitate answers on a test", decía una especialmente clara. "No es tanto el qué, como el cómo", respondían rápidamente en el debate hispano. "Más que los contenidos lo que falla son las metodologías, los enfoques" continuaba ese mismo participante. "Me hubiese encantado que alguien nos hubiese enseñado a poder desenvolvernos mejor en el mundo real. Enseñar a trabajar en equipo y potenciar lo mejor de cada uno para conseguir un fin colectivo. Dejar de educar en masa para centrarse en las cualidades específicas de cada individuo. Que hubiesen quedado atrás los sistemas individualistas de educación ya que nos vuelven a todos más egoístas" aportaba varios comentarios más abajo Mireia. "Me hubiera encantado aprender a aprender y no que me enseñaran a memorizar datos que olvidaba después del examen. Aprender a tomar mis propias decisiones y a equivocarme", respondía en la misma línea Casilda."

"It has me thinking about what it would mean to improve online classes. A few ideas come to mind: Use multiple platforms. I'm not against using an LMS as a central hub. However, I think it's valuable to experiment with the types of productivity tools you will actually use outside of a classroom. Use Google Docs to share ideas, create surveys, and ask questions. Use Google Hangouts to meet as a group. Go project-based. I haven't figured this out entirely with my first class but my hope is that we can go fully project-based in the same way that my face-to-face class is. In fact, the asynchronous nature of online classes actually means there is a better potential of creating a project-based culture that mirrors the way people actually work on projects. Make something together. I use a collaboration grid with co-creating and communicating on separate spectrums (x-axis) and multimedia and text on another spectrum (y-axis). This has been an effective way to think through collaborative tools that allow students to co-create. Embrace a synchronous/asynchronous blend: I love using Voxer because students can speak back and forth in the moment. However, if they miss it, they can listen to it later. The same is true of using a Google Hangouts On Air. Make it more connective. We tend to treat online instruction as if it is a linear process and we don't do enough to link things back and forth and connect ideas, resources, discussions and content creation in a seamless, back-and-forth nature. Incorporate multimedia. It's a simple idea, but I create a short video at the beginning of each week and I encourage students to create video and audio as well. This has a way of making things more concrete. There's something deeply human about hearing an actual human voice. I know, crazy, right? Go mobile. I don't simply mean use a smart phone. I mean assign some things that allow students to get out in the world and create videos, snap pictures, or simpl

"... In addition to serving as a great explanatory example of the potential danger of AI, I have realized that paperclip maximizer is also a perfect allegory for capitalism. Where the artificial intelligence sought to maximize paperclips, the capital maximizer seeks to maximize capital. ... While this story of the capital maximizer might strike some as the anti-capitalist rantings of socialist idealism, it is not meant as such. Capitalism is the most powerful machine that humans have ever created. It can realize the benefits of technological progress and leverage them to improving the human condition better than any other economic system yet devised. The problem is in viewing the growth of capital as an ends and not a means. If we do not demand that our systems maximize the well-being of humans and the environment which sustains us, then all is lost."

"This is not an environmental book, even though it is concerned with the environment. It is not a book to save the world, even though the world is clearly in trouble. Ultimately, A Matter Of Scale is a book about survival; about ensuring that every individual human has the means to save herself or himself from the crisis that is unfolding. And there most certainly is a crisis; like the waves of a surging river; small and irregular at first, but growing larger, creating whirlpools, rising in treacherous white water, and eventually inundating everything in its path. People know that the climate is changing, that species are being removed from the Earth at a rapidly increasing rate, that entire ecosystems are becoming shadows of their former richness; they know, but they do not understand. The environmental crisis is closing in on humanity from all directions, yet the crisis barely registers on this culture's list of problems. As we stand, humanity is doomed to a collapse that will leave only a few nomads, and a toxic, barely survivable Earth in its wake."

"... The prediction is a pretty damn good one. The world is now about 1 degree Celsius (1.8 degrees Fahrenheit) warmer than it was and carbon dioxide levels are at 415 ppm. The estimate was part of Exxon's "high case" scenario, which assumed fossil fuel use would quicken and that the world would be able to tap new reserves in the late 2000s from at the time unreachable shale gas. The memo also warned that the extra carbon dioxide would enhance the greenhouse effect and that an "increase in absorbed energy via this route would warm the earth's surface causing changes in climate affecting atmospheric and ocean temperatures, rainfall patterns, soil moisture, and over centuries potentially melting the polar ice caps." Honestly, it gave me chills re-reading the memo 37 years later. The company clearly described all the horrors we're facing now. The only thing its scientists got wrong was that what they called "potentially serious climate problems" wouldn't emerge until the late 21st century. So much for that. ..."

"In 1973, near the height of the 'population bomb' panic, a computing programme called World1 offered up some predictions for the future. It anticipated a grim picture for humanity based on current trajectories. Tracing categories such as population, pollution and natural-resource usage, World1 calculated that, by 2040, human civilisation would collapse - a century after the best year to have been alive on the planet: 1940. This film was originally broadcast by the Australian Broadcasting Corporation (ABC) News as part of a report on predictions for the coming decades made by cutting-edge computing technology and leading thinkers of the time. The second segment features interviews with members of the Club of Rome, an elite think tank composed of government officials, academics and business leaders focused on the future of humanity. Their view is a bit sunnier, anticipating a world where global governments are forced to cooperate to solve complex problems, people widen their cultural horizons and work fewer hours, and limited consumption - not wealth - becomes a mark of prestige. Viewed today, it makes for an engrossing artifact, raising far more questions than it answers about humanity's ability to effectively predict its future and correct its course."

"Air pollution may be damaging every organ and virtually every cell in the human body, according to a comprehensive new global review. The research shows head-to-toe harm, from heart and lung disease to diabetes and dementia, and from liver problems and bladder cancer to brittle bones and damaged skin. Fertility, foetuses and children are also affected by toxic air, the review found."

"When you pick your tomatoes, if you want to keep them longer, you have to find a way of reducing the temperature. As availability of electricity at village level can be a problem, ways have to be found to lower the temperature of this fragile crop. Some farmers at Dambatta in Kano State, Nigeria have used local mud bricks to make a very effective cooling chamber."

"Dan Meyer es un profesor de matemática de secundario en Estados Unidos, un profesor "común y corriente" que da clases con la genuina intención de que sus alumnos aprendan matemática. Pero la verdadera matemática, esa que consiste en buscar estrategias para resolver problemas, en entender bien qué información hace falta para resolverlo y qué información "sobra"… la que involucra pensar en serio y no limitarse a resolver problemas de manera automática. En esta charla TED da su opinión acerca de algunas cosas que están fallando en la enseñanza en matemática y agrega propuestas para mejorarla. Lo interesante es que no habla de grandes cambios a nivel de la política pública o de cambios en los programas, sino de esas pequeñas vueltas de tuerca que cualquier profesor puede hacer por sí mismo en su aula con sus alumnos. Es más, son pequeñas modificaciones que reflejan una mirada sobre la educación que puede ser trasladable a otras áreas del conocimiento además de la matemática. Rescato en particular estos fragmentos de esta charla: "Este es un ejemplo de un libro de física. Y se aplica de igual manera a los de matemáticas. Vean primero aquí que tienen exactamente tres piezas de información, cada una de las cuales irá en una fórmula en alguna parte, eventualmente, que el estudiante terminará calculando. Creo en la Vida Real. Pregúntense ustedes mismos, qué problema han resuelto, alguna vez, que fuera importante resolver, y que tuvieran toda la información anticipadamente, o que no tuvieran muchísima información, y que tuvieran que filtrarla, o que no tuvieran suficiente información, y tuvieran que conseguir alguna. Estoy seguro de que estarán de acuerdo en que ningún problema importante es como este. Y el libro, yo creo, sabe como atontar a los estudiantes." "Ningún problema que valga la pena resolver es así de simple". Dan Meyer Twitter: @ddmeyer Blog: http://blog.mrmeyer.com"
