"Did you know that your tweets have an expiration date on them? While they never really disappear from your own Twitter stream, they become unsearchable in only a matter of days. At first, Twitter held onto your tweets for around a month, but as the service grew more popular, this "date limit" has dramatically shortened. According to Twitter's search documentation, the current date limit on the search index is "around 1.5 weeks but is dynamic and subject to shrink as the number of tweets per day continues to grow."

The game Chromaroma, developed by Mudlark Studios, answers these questions and more. It is basically foursquare for public transit-using London's Oyster Card system, users' trips are recorded and reported to Chromaroma. There is a lag time around 72 hours, after which a player's trips appear on their personal page and are displayed in a slick, 3d representation of the city. The recording aspect is only the beginning-players are assigned quests to go certain places or accomplish their commute in a different way, and can "capture" locations for one of four teams, which players join upon signing up.

"We intend for this site to be a central location for information on how to move your data in and out of Google products. Welcome. Click on any product link on the left hand side for more information on how to liberate your data from (or to!) that product. The Data Liberation Front The Data Liberation Front is an engineering team at Google whose singular goal is to make it easier for users to move their data in and out of Google products. We do this because we believe that you should be able to export any data that you create in (or import into) a product.

Classrooms have come a long way. There's been an exponential growth in educational technology advancement over the past few years. From overhead projectors to iPads, it's important to understand not only what's coming next but also where it all started. We've certainly come a long way but some things seem hauntingly similar to many years ago. For example, Thomas Edison said in 1925 that "books will soon be obsolete in schools. Scholars will soon be instructed through the eye." I'm pretty sure this is exactly what people are saying these days about the iPad.

"Using games in the classroom - This is a presentation to pre-service teachers about the affordability and importance of game-play. Low-end."

"Last week my wife and I told our 13-year-old daughter she could join Facebook. Within a few hours she had accumulated 171 friends, and I felt a little as if I had passed my child a pipe of crystal meth. I don't mean to be a spoilsport, and I don't think I'm a Luddite. I edit a newspaper that has embraced new media with creative, prizewinning gusto. I get that the Web reaches and engages a vast, global audience, that it invites participation and facilitates - up to a point - newsgathering. But before we succumb to digital idolatry, we should consider that innovation often comes at a price. And sometimes I wonder if the price is a piece of ourselves. "

"Mobile devices are now found in the hands of most children, and school leaders are using that to their advantage by incorporating devices that students already own into classroom lessons and projects.Concerns remain about students who are unable to purchase or borrow a device for use in the classroom, but districts might find creative ways-such as asking local businesses or community organizations for help-to provide devices in such instances, advocates of the trend say."

Since the internet is now an integral part of teachers' lives, it's important that they are aware of the tools and resources available online that could help them impart education in an effective and efficient manner. The following lists mentions 20 such tools. If you are a teacher or an academician, do check them out.

"Connect.ed is an innovative, self-paced cybersafety education program offered by the Australian Communications and Media Authority (ACMA) as part of Cybersmart. Connect.ed provides teachers with the flexibility of a self paced environment to learn about current online behaviours of students, potential risks involved in these activities, a teacher's and school's duty of care and the appropriate tools, resources and strategies to help students to have safe and positive experiences online."

"On Monday Steve Wheeler wrote a blog post on mobile and student owned devices which I thought I'd respond to here. Please read the post and comments and then come back. In answer to your question "Should students' personal devices become a part of the delivery strategy..." without a doubt we should be considering mobile. It would be foolish not to consider mobile. However this is not to say that mobile must dominant the agenda."

Something rather interesting is happening to privacy, in the breakneck world of the internet. It's being privatised.

Games based learning is supposed to be the next big thing. So when I revamped a unit of work for Year 10 based on designing scientific investigations, I decided to "gamify" the unit of work. I was inspired by a YouTube video by Seth Priebatsch on gamification, where elements of gaming can be added to education. After also seeing presentations by Dean Groom and Ben Jones I have  come up with my first "gamified" set of learning experiences.

"Game-based learning (GBL) is a seemingly simple concept - learning through the use of games. But wait, let's look a little closer. Most people see the term "game-based learning" and think of students playing some sort of educational computer game. But, there's more to GBL than just that. Let's take a look at GBL in terms of the game and pedagogical considerations:"

This report is designed to give an accessible overview of media literacy among UK children and young people aged 5-15 and their parents/ carers (-1-). The purpose of this report is to support people working in this area to develop and promote media literacy among these groups. This report is the third full report since our survey began in 2005. It is therefore able to show trends over time for many of the questions asked. Due to different survey periods and focus, some comparisons are made with 2005 and 2007 data, and others with 2007 and 2008, and change over time is highlighted against either 2007 or 2008 accordingly.

Dr. Tony Wagner, co-director of Harvard's Change Leadership Group has identified what he calls a "global achievement gap," which is the leap between what even our best schools are teaching, and the must-have skills of the future: * Critical thinking and problem-solving * Collaboration across networks and leading by influence * Agility and adaptability * Initiative and entrepreneurialism * Effective oral and written communication * Accessing and analyzing information * Curiosity and imagination

"A while back I wrote about my thoughts on the ipad craze. At that time I didn't own one. I do now and have had it for about 4 months. I like it. I'm not WILD about it, but I like it. I enjoy going out and finding apps that I think might help me be more productive on it, and I like finding challenging games, and I like the interface a lot. Would I buy a cart full of them for school. Absolutely NOT."

"Spider Scribe is an online mind map creation service. Spider Scribe can be used individually or be used collaboratively. I've reviewed a lot of mind mapping tools over the years. What jumps out about Spider Scribe is that users can add images, maps, calendars, text notes, and uploaded text files to their mind maps. Users can connect the elements on their mind maps or let them each stand on their own."
