In one sense, that's awesome. A person can go back and analyze the hows and whys, but it also could easily lead to students never really bothering to learn and understand those hows and whys. That would not be good.
What do you think? Is this totally fantastic, merely useful, or will it make us all too dependent on computers (and lost when those computers malfunction)?
I'm conflicted. On the one hand, I love, love, love technology and think it's awesome that someone was even able to come up with this app. On the other, well, I'd hate to have fewer people motivated to learn new things.
Have a fantastic day!
