From an instructor’s perspective, Twitter offers the ability to prompt students throughout the learning process by asking them to reflect on learning strategies and time management, which ultimately raises metacognitive awareness.

While the use of Twitter only shows a slight increase in grades (about .5 percent), it substantially improves engagement and motivation

Twitter enhances the social presence outside of the classroom, which leads to overall course satisfaction.

In the schools, too, there is no reward for helping others (indeed, it is heavily penalized). Suppose educational achievement was measured at least partially according to how much (and how well) you helped others. The value of the achievement would increase if the person is a stranger (and conversely, decrease to zero if it's just a small clique helping each other) and would be in proportion to the timeliness and utility of the assistance (both of which can be measured).

Suppose instead students were rewarded for cooperation. Not collaboration; this is just the school-level emulation of the creation of cliques and corporations. Cooperation, which is a common and ad hoc creation of interactions and exchanges for mutual value.  Cooperative behaviours include exchanges of goods and services, agreement on open standards and protocols, sharing of resources in common (and open) pools, and similar behaviours. Imagine receiving academic credit for contributing well-received resources into open source repositories, whether as software, art, photography, or educational resources. Imagine receiving credit for long-lasting additions to Wikipedia or similar online resources (we would have to fix Wikipedia, as it is now run by a gang of thugs known as 'Wikipedia editors'). We can have wide-ranging and nuanced evaluations of such contributions, not simple grades, but something based on how the content contributed is used and reused across the net (this would have the interesting result that your assessment could continue to go up over time).

There is, again, no reason why public service cannot be incorporated into individual assessment. Adding value to fire and police services by means of monitoring and reporting (not the piece-work model of something like CrimeStoppers, but actual prevention), supporting environment by counting birds, sampling water, servicing sports events by acting as a timer or umpire - all these can add to a person's assessment. I'm not thinking of the simple sort of tasks grade school students can perform. Indeed, a person hoping to attain a higher level qualification would need to contribute to the public good in a substantial and tangible way. Offering open online courses (that are well-subscribed and positively reviewed by the community) should be a requirement for any graduate-level recognition. The PhD used to be about offering a unique research contribution to the field; now it's about paying tuition and being exploited as a TA. These three things - helping others, being cooperative, contributing to the public good - are obviously not easy to assess. To be sure, it's far easier to ask students simple questions and grade the number of correct responses. But assessing students in this way, far from measuring putative 'content knowledge', is really an exercise in counting without any real interest in what is being counted. It acts as an invitation to cheat, as it places self-interest ahead of the values it is actually trying to measure.

A pair of MIT Media Lab alums have come up with a do-it-yourself kit for making smart environments. David Carr and John Kestner, partners in the industrial design firm Supermechanical, have developed a small, durable, inexpensive remote sensor node, and an easy-to-use web app that turns data from the sensor node into timely information. The system, dubbed Twine, lets you tie everyday objects into your digital life.

Twine is a palm-size block of rubber that contains a WiFi node, temperature sensor and accelerometer. It’s powered by two AAA batteries or a mini USB connection. And it has a port where external sensors can connect. The initial external sensors are a magnetic switch, moisture sensor and a breakout board for building your own sensor. Supermechanical is also considering an RFID reader, pressure sensor and current sensor.

Times are changing. Kathy Sierra features a timeline on her blog which suggests that the 1970s and 80s were about how well we could learn, the 1990s and 2000s focused on how fast and how much we could learn, whilst today's education should be based on how much we can unlearn. And, she says, learning to let go of old and out of date rules is one of the skills we all need to develop. Futurologist Jack Uldrich is applying the same principle to the medical profession, arguing that the key to unlearning is to come to the realisation that 'we are all in a fog', and can't clearly see the future. Unlearning will be a strategy for coping with rapid change and uncertainties, he argues.

YouTube announced a new batch of partners that were added to its Education Channel today and noted that nearly 80% of the viewership of educational content on the site came from outside the United States. Less than 70% of the site's total traffic is International, so the educational content is disproportionately viewed by global audiences. Both YouTube and iTunes U are serving up huge quantities of educational content to a world already in the throes of a 50 year revolution in global education. In some ways they represent exactly the kind of education that a new world needs, too: learning that augments existing education and fosters life-long development of non-routine analytical and interactive skills. That's a recipe for good times. YouTube now hosts more than 500,000 educational videos, on a wide variety of topics. The new mobile-friendly iTunes U also offers 500,000 educational resources and says that 60% of its viewership comes from outside the United States. This global consuption of US-created online educational content may be the newest chapter in a radical transformation of global education over the past 50 years. Life in this world is not like it used to be just a few decades ago, and the availability of world-class education on-demand, at almost no cost, is likely to help things change all the more as this century unfolds.

A trend began, at least in the United states, as far back as 1985: demand for "routine manual skills" has held relatively steady, demand for non-routine manual skills has plummeted. Demand for routine cognitive skills climbed through 1970, then fell. What's hot? Non-routine analytic and non-routine interactive skills. Those are things that a good YouTube or iTunes U video about world history or global ecology can help improve, your non-routine analytic and interactive skills. More than for just economic well-being, those are skills that positively impact quality of life in many ways.

Take a look at your web site and search for unnecessary details that could bore the client. Very often we see the description of some products that may seem appealing at first sight but in the end they lack important information that may persuade us to buy it. Redesigning your web site is something that you should do quite often in order to make it effective for a long period of time. Updating, always bringing something new to audience, using the latest technology instead of hard-coding, brings you the company you’ve always dreamt of. As Leonardo da Vinci said best “Simplicity is the ultimate sophistication”.
