"And lucky you, this is just the year to do it. It is Code Year, actually, according to Code Academy, which helps people learn to code. "Sign up for Code Year to start receiving a new interactive programming lesson every Monday," touts the web site, and "You'll be building apps and websites before you know it!" I tried out the first few lessons, and it strikes me as a gentle way to learn to program. The lessons are small, focused, and introduce concepts with demonstrations that are easy to understand. It is therefore likely your best chance to learn to code if you aren't in school. "

Ideas for using QR codes in the classroom, plus some pre made QR code activities (such as a QR code treasure hunt)

"The Google Open Source Program is announcing a new outreach effort, aimed at 13- to 18-year-old students around the world. Google Code-in will operate in a similar fashion to Google's Summer of Code, giving students the opportunity to work in open-source projects."

"They're easy to overlook for those who don't know what they are. But those in the know are using and exploring this next generation of bar codes."

a good example of prime numbers in nature -- and why they are important, e.g., for a kind of cicada which has a 13-year cycle... "Because 13 and 17 are both indivisible this gives the cicadas an evolutionary advantage as primes are helpful in avoiding other animals with periodic behaviour. Suppose for example that a predator appears every six years in the forest. Then a cicada with an eight or nine-year life cycle will coincide with the predator much more often than a cicada with a seven-year prime life cycle. These insects are tapping into the code of mathematics for their survival. The cicadas unwittingly discovered the primes using evolutionary tactics but humans have understood that these numbers not just the key to survival but are the very building blocks of the code of mathematics."

Scannable bar codes may be just what you need to spark some student interest in your classroom - read on to learn how to use them to showcase your student work and give some life to your classroom's infographics.

Seeing many possibilities with this - like a QR code but transmitted by sound, great demo video on this site

As mobile learning becomes more and more prevalent, we must find effective ways to leverage mobile tools in the classroom. As always, the tool must fit the need. Mobile learning can create both the tool and the need. With safe and specific structures, mobile learning tools can harness the excitement of technology with the purpose of effective instruction. Using QR codes for instruction is one example of this.
