"Improve your vocabulary" This is a simple tool that will assist with learning English (to Advanced English), Spanish, and Polish vocabulary. More languages may follow. It can be used online or with a free Android app. It is similar to a lot of other language learning applications. You can create lists of words and phrases that you want to learn or you can select a list that was made by someone else and shared to the Vocabla library. You can study each list as a type of flashcard and when you are ready you can take a practice quiz. Teachers might like using Vocabla to create a list of words and share with their class. All the students could use the list to study on their own

"FETCH! with Ruff Ruffman, is making a movie! Of course, he's in over his head and he needs your help, like, yesterday. In this Augmented Reality, multi-player game, you need to keep up with lunch orders from Ruff's movie crew. The challenge is keeping track of how many pieces of sushi everyone wants."

"Reckon you can spot a YouTube video captured on a smartphone camera? It's not hard - they're often the ones that look like they're shot on "spin cycle". Many new, dedicated video cameras include optical image stabilisation (OIS) that takes out much of the shake from video clips. Even most budget models now include a digital version that can remove minor hand-shaking. But unless you have a HTC One, iPhone 5 or Nokia Lumia 920 in your pocket, most smartphones have nothing to offer for video stabilisation. But it can be fixed - even if you've already captured your video."

"Ever needed custom formatted sample / test data, like, bad? Well, that's the idea of this script. It's a free, open source tool written in JavaScript, PHP and MySQL that lets you quickly generate large volumes of custom data in a variety of formats for use in testing software, populating databases, and... so on and so forth."

"iOS 7 brings a significant user interface overhaul to Apple's mobile devices, and though it's best to be experienced and used first hand, screen shots can do a fair job of demonstrating the differences. If you're not a developer and can't use the beta releases yourself, then comparing iOS 7 to iOS 6 side-by-side can give an appreciation for the changes ahead, so we rounded up a few comparisons of the home screens, common apps and app interfaces like Notifications, Siri, Messages, Mail, multitasking, and Weather, and also a large side-by-side chart showing the differences between icons in both iOS versions. Take a look."

"We're very happy to announce the latest version of Gliffy Online-now completely rebuilt around an HTML5 editor with ultrafast response rates and an impressively improved feature set. The next time you use Gliffy Online you'll notice the dramatic difference. HTML5 offers you stable, secure access to built-in features unavailable using a plugin like Flash. "

At first I wasn't sure about the poor range of (physics/science) books I found in the subject sections, but when I searched using more specific terms (like energy, electricity etc), there were loads of multi-page docs (PDFs) available to download. Worth exploring a little more deeply.

"The web today is a growing universe of interlinked web pages and web apps, teeming with videos, photos, and interactive content. What the average user doesn't see is the interplay of web technologies and browsers that makes all this possible. Over time web technologies have evolved to give web developers the ability to create new generations of useful and immersive web experiences. Today's web is a result of the ongoing efforts of an open web community that helps define these web technologies, like HTML5, CSS3 and WebGL and ensure that they're supported in all web browsers. The color bands in this visualization represent the interaction between web technologies and browsers, which brings to life the many powerful web apps that we use daily."

"Not that long ago, there was only the television, which theoretically could be kept in the parents' bedroom or locked behind a cabinet. Now there are smartphones and iPads, which wash up in the domestic clutter alongside keys and gum and stray hair ties. "Mom, everyone has technology but me!" my 4-year-old son sometimes wails. And why shouldn't he feel entitled? In the same span of time it took him to learn how to say that sentence, thousands of kids' apps have been developed-the majority aimed at preschoolers like him. To us (his parents, I mean), American childhood has undergone a somewhat alarming transformation in a very short time. But to him, it has always been possible to do so many things with the swipe of a finger, to have hundreds of games packed into a gadget the same size as Goodnight Moon."

The Mad Video is a new service for creating interactive videos. The service is kind of like ThingLink for videos. Using The Mad Video you can take a video that is hosted on YouTube and insert interactive tags. The tags can link to websites, images, or other video clips. People can see your tags when they place their cursors over your video. You can add multiple tags to each video in your The Mad Video account.

"Welcome to TeleRead's newest how-to series! We'll be exploring a wonderful tool called Evernote, and its many uses for readers who want to organize and synthesize books, articles, quotes, websites, ideas and other information."

The demo, which is an extended version of the previously released video, highlights numerous effects including snow, lighting, grids, and other ways in which IllumiRoom changes the user's playing space. Reports continue to suggest that Microsoft is likely to implement the concept into its next Xbox design, although no official confirmation has been granted just yet.

Oolone is a search engine like Google, but it uses visual technology to help you find results. Instead of text results, we bring up pictures of results. You can download a sample lesson plan from the site and more ideas and lesson plans are available on Edmodo.

"How will mobile phone technology such as Google Glass - the wearable gadget that searches for whatever we look at - and social networks like Facebook and Twitter influence our searches? Should we be concerned that sensitive personal information is being filtered through a small number of companies?"

From Edudemic "Research involves a lot of information and data which have to be easily and efficiently managed under tight deadlines and time restraints. The following steps will offer you a bit of insight into how you can become a better researcher using some simple web tools like mind maps and bookmarklets."

"When Google Plus was announced in 2011, many people were skeptical that the social network would be able to gain ground against the likes of LinkedIn and Twitter, let alone the industry-leading giant Facebook. After all, looking at the Palo Alto-based Google previous cracks at a similar experiment, it would appear that social media was one area that Google struggled with."
