TinEye - Reverse Image Search

TinEye is a reverse image search engine.  You can upload an image from your computer and search the Internet for it.  You can also paste a image URL and find other places that the image exist on the Internet.  What is neat is that you don't necessarily have to have the same file name.  TinEye will use Image Identification Technology, not keywords, metadata, or watermarks.  The site currently has 1.6 billion images indexed for you to use in your search.

TinEye would be a great site to use to check on students using images in a presentation but did not site the source for where they received the image.  It will also help with those teachers who have students publishing websites to ensure that students did not use copyrighted photos. 

Livestation


Livestation is a site that allows you to watch live TV and listen to radio.  The TV stations are centered around news stations, but Livestation would be a great tool for classrooms that are studying current events and want to see news from other parts of the world.  There are several channels that would be of interest to teachers and provide an alternate source to news.  News stations include Al Jazeera, BBC, NASA, and United Nations.  A valuable news source separate from network and cable news stations that most, at least Americans, are used too.  You can also watch the news from their mobile station on the iPhone and Blackberry.

OneExtraLap - Social Quizzing


OneExtraLap is a site dedicated to the idea of creating a quiz, making it social, and then turning that quiz into a competition.  It allows you to create and take compelling and content rich quizzes while competing with friends and earning points and badges.  Sign up is easy.  Username, Password, and Email address.

Each quiz is limited to 9 questions, but each question can have up to 9 answers, so you could also turn your quiz into a survey.  You can also tag your quizzes making it easy for students to find them online and take them.  I think a site like this could really take off if they created a way to create teacher accounts.  It would be a great way to create competition online for your students and provide another way for your to assess your students.  It is still in its infancy, but I think the site shows some promise of being useful and neat.

Khan Academy


Khan Academy is a site that offers TONS of videos related mostly to Math and Science.  The videos are basically tutorials or explanations on how to solve equations.  From their site "The Khan Academy is a not-for-profit 501(c)(3) with the mission of providing a world-class education to anyone, anywhere. Despite being the work of one man, Salman Khan, this 1600+ video library is the most-used educational video resource as measured by YouTube video views per day and unique users per month. We are complementing this ever-growing library with user-paced exercises--developed as an open source project--allowing the Khan Academy to become the free classroom for the World."

There are some videos for other subjects, but they don't compare to the number of videos for Math and Science.  Not a replacement for your lessons, but a great supplement to what you are teaching and maybe even in a method you might not normally teach it.
