My recent comments during a conversation among school technology folks trying to budget for computer replacement, speculating whether 5 or 7 years was the right cycle."At the exponential rate that technology is changing, I also think we must also be speaking in turns of "technologies" not specific pieces of technology and be planning for more exponential changes in technology - instead of speculating whether we should replace our desktops every 5 or every 7 years. Looking back at Thomas Edison's prediction of a time when there would be a phonography in every home and...Thinking back at Ray Kurzeil's prediction (1999 MIT Inventor of the year)"just as the Industrial Revolution reshaped America at the dawn of the 20th century, the information revolution is resahping the world at the dawn of the 2st century. The expontential growth of technology in the first two decades of the 20th century matched that of the entire 19th century.The exponential growth of the technology in the first 5 years of the 21st century will invenitably inexorably, match that of teh entire 20th century." Looking around the corner at the technology that teens predict will be obselete by 2015 http://mit.edu/invent/n-pressreleases/n-press-06index.html and Looking ahead at the technology on the horizon (The Horizon Report: http://wp.nmc.org/horizon2011/)I'm so happy to be working in such a dynamic field as educational technology --- from the lady who use to have $75 per machine in her budget for the annual cleaning and maintenance of the typewriters in my lab
Several times recently I've been asked how to add audio to Google Presentations. Here are a few ideas that might work.
SlideRocket According to their description in the Google Apps Marketplace, they have "reinvented presentations with its feature rich, innovative platform that lets you create, manage, share and measure your presentations in one complete and integrated application". This includes audio features. I have not added this to our domain yet, but plan to and play with it soon
Screenr, Jing, or other Screen capture solutions could also be used. Simply play your Google Presentation and narrate while you are recording it using your favorite Screen Capture solution. Many of these also offer hosting of the completed movie.
Let me know which ones you try and any tips you come up with in sharing these.
