So, I think that there are two sides to the argument about the use of iTunesU.
Side #1: Oh no. Another online tool for delivering course content. First we had to learn how to create websites, then Moodles, now it's iTunesU. Should I bother to learn how to use this if there is just going to be another flavour of the month around the corner? Is this another way that someone is trying to use to replace teachers?
Side #2: Oh no. There is another tool for delivering course content. This means that I have to try and move all of my content from my Moodle and Website to iTunesU. I guess that isn't such a horrible thing. The format is very easy to use and requires very little work to actually create and maintain. Since it looks like iPads are the way of the future, I should try and stay ahead and start to put all of my resources on iTunesU. This will work out well for my students as well. They will be able to access course content digitally using their iPads which means that my course will be accessible for all.
Either way, we are going to run into some resistance. There will always be the eager teachers willing to jump on to whatever bandwagon their school board tells them to. However, there will always be those teachers who have become jaded from falling for this too many times. I hope that I am somewhere in the middle. I like to think that iPads and iTunesU will be here for a while and will make my time spent on it valuable.
