There's an awesome application out there called Miro. Miro is a free application that turns your computer into an internet TV video player. You can download it here for Windows, Mac, or Linux. Miro is open source...which has gotta' make you feel good, too! I've found that Miro plays just about anything, but its strength lies in that there are literally thousands of channels that you can subscribe to and download internet TV shows.
So...how does this play into education? There are many channels dedicated to such topics as nature, science, history, space, tutorials and so much more! I just watched a very interesting show from NASA and a news show compiled from newscasts from Middle East TV stations! The video quality is superb! Students can download their own shows or better yet, the teacher can download the content to a master computer and show the video up on a screen for the entire class! Miro is a powerful tool that can really enhance learning in your classroom...check it out today!
