"1. Blogging enables reflection. This is true for both students and educators. Too often do we go through our days, class to class, with minimal opportunities for reflection on our experiences or the information that we have acquired along the way. Blogging offers the opportunity to take a step back and connect with our learning and place it in the context of the bigger picture. Make reflection an assignment or part of another assignment - it is an important component to learning. For students: This is not the easiest thing to accomplish - blogging takes time and that is a finite resource during a busy class period. There is great opportunity in academic support periods or advisory classes for students (particularly in 1:1 schools) to blog. Many advisory classes take place throughout the day, which is a great break point for students to create based on their learning from that day. For teachers: This type of reflection can and should be compiled into your lesson planning for future lessons. Take what you learned from teaching and learning that day and incorporate it into the next day's lessons. Find time to do this during a conference period during your day or right after school. Yes, it is tough to get in the habit of doing a new thing - but once you start using reflection through blogging, I think that your lesson planning will be easier and much more meaningful. 2. Develop an Authentic Audience An authentic audience is a great way to increase rigor and in all of my experiences has led to increased performance by students. Authentic audiences in blogging could mean any number of things - family members, students from other classes, students from other buildings, other teachers, individuals interested in the content from around the world, etc. A student knowing that their work may be seen by people other than what they consider their 'typical audience' (read: teacher) typically spends more time and exerts more effort to creating a quality p

"La economía humana es actualmente demasiado grande para ser sostenible. Lo sabemos porque la Global Footprint Network, que metódicamente hace seguimiento de los datos, nos informa de que la humanidad está usando actualmente recursos equivalentes a una Tierra y media. Podemos usar temporalmente los recursos más rápido de lo que la Tierra los regenera únicamente tomándolos prestados de la futura productividad del planeta, dejando menos para nuestros descendientes. Pero no podemos hacerlo durante mucho tiempo. De una forma u otra, la economía (y aquí estamos hablando principalmente de las economías de los países industrializados) debe reducirse hasta que subsista con lo que la Tierra puede proveer a largo plazo. Decir "de una forma u otra" implica que este proceso puede ocurrir tanto de forma voluntaria como involuntaria; esto es, si no encogemos la economía deliberadamente, se contraerá por su cuenta una vez alcanzados límites innegociables. Como he explicado en mi libro El Final del Crecimiento, hay razones para pensar que esos límites están empezando a afectarnos. Desde luego, la mayoría de las economías industriales están frenándose o encontrando dificultades para crecer a los ritmos que eran comunes durante la segunda mitad del siglo pasado. La economía moderna ha sido concebida para requerir crecimiento, así que la contracción causa supensión de pagos y despidos; la simple falta de crecimiento se percibe como un grave problema que requiere la aplicación inmediata de estímulos económicos. Si no se hace nada para revertir el crecimiento o adaptarse anticipadamente al inevitable estancamiento y contracción de la economía, el resultado más previsible será un proceso intermitente, prolongado y caótico de colapso que se prolongará durante muchas décadas o quizás siglos, con innumerables víctimas humanas y no humanas. Ésta puede ser, de hecho, nuestra trayectoria más probable. ¿Es posible, al menos en principio, gestionar e

"Evaporative coolers have been known to purveyors of low-cost, sustainable technologies for years. Without the need for electricity, these cold containers have kept produce fresh from farms to tables, protecting against post-harvest losses in the field and food spoilage in hot pantries worldwide. Now the concept has been applied to air conditioning. Manoj Patel Design Studio in Vadodara, Gujarat (India) has built evaporative air conditioners that can cool a room for days on a single tank of water. The studio designs new products from recycled materials, and they built their air conditioners from ceramics and stone, integrating them with potted plants. By filling rows of ceramic tubes with water, the prototypes maximize their surface area for optimal evaporation while retaining a small footprint. ..."
