Part of the student expert assignment involves recording your p-k and either posting it yourself or sending it to me so I can post it.
If you have the most recent version of Powerpoint for Windows, these are the instructions you should follow. It can take a little while to encode the video once you’re done, but the product you’re looking for is a .wmv video. It’s not clear to me whether you need to click to advance each slide with this method… if you do, it’s not a big deal if you’re not precisely within the 20-second timeframe for each slide.
On a Mac, you should use Quicktime’s built-in Screen Recording feature to record your Powerpoint. Get your presentation ready to go, and follow the instructions here. Make sure you’ve set the audio input (the little upside-down triangle on the right-hand side) to “Internal Microphone,” or whatever microphone you’re using.
