So, here is a high school instructor making mobile happen for his students. The claim was made, and I have no reason to question it, that he is teaching a high school calculus class entirely via mobile devices. He didn't go into details about it, other than to say it's possible. It's remarkable when how normal and commonplace such an idea can be communicated. I mean, no one in the room shouted and slapped their heads with the palms of their hands. I looked around to see if eyebrows were raised, but the reaction was more like, okay whatever, moving on.
His description of the different contexts of mobile was intriguing. The message is "You have to start somewhere." So, jump in where you can and do something. If you need to use free apps to deliver information -- while it may not capitalize on the mobileness of these devices, it's still something.
The real power and empowering of mobile devices he claims is when students can be guided to apply the informal learning and social functions in the interest of learning (practice).
Here are my visual notes:
