Do you have an iPhone or iPod touch? If so, you and your students can use Blackboard (kind of) from your device. Go to the app store on your iPhone or iPod touch and search for Blackboard Mobile Learn. Install it for free.
Once the app is installed on your device, click it and search for Alaska. Choose University of Alaska Anchorage, and then you can log in and access your classes! This has limited use at this time but the university is looking into a better version that we would have to pay for.
