Mashups for everything

So what is a Mashup?
Wikipedia defines 4 differnt types of Mashups:
Mashup (digital), a digital media file containing any or all of text, graphics, audio, video, and animation, which recombines and modifies existing digital works to create a derivative work.
Mashup (music), the musical genre encompassing songs which consist entirely of parts of other songs.
Mashup (video), a video that is edited from more than one source to appear as one.
Mashup (web application hybrid), a web application that combines data and/or functionality from more than one source.

The best site I have found showing the many Mashups is http://www.programmableweb.com/
The site has a listing over 2800 different Mashups. From Celebrity Mashups,
http://www.programmableweb.com/tag/celebrity , to Mapping Mashups http://www.programmableweb.com/mapping , I shared with a Professor of Archeology a Mapping Mashup and now he uses that tool to show his students the various digs he has been on around the world. On his class website they are able to see his past explorations marked on the map. Then the student can click on that area of the map and see a descripition of the dig, the findings and photographs. I'd link you to his class site but it is for students. Of course you can sign up for his class if you want to move to the St. Louis area and pay the tution fee.

If you know me you know I love all kinds of car racing. Here is a wonderful little NASCAR Mashup http://www.programmableweb.com/mashup/nascar-map-race-week which is a
community site that helps NASCAR fans find and recommend places to eat (did I mention i Love BBQ) and stay near the track, as well as find events leading up to race day. Custom maps can be emailed to friends, or downloaded to Google Earth.

So if you haven't thought about using mashups in your teaching I'd suggest giving it a try! I think you'll find your students will love it!
