I heard about this web site in the fall, but hadn't had time to figure it out until this week when I started a debate about our current topic of study, German headscarves. 
     After laboriously copying every student's personal e-mail, I'm about to send an invitation to everyone to participate in this debate when a flash of caution overtakes me.  Though I'm very excited because I know my debate-loving students would greatly benefit from the site, I realize that I really don't know a lot about the site and maybe I should wait a little bit to see what happens.  When I return to my computer a short while later, I find someone had already posted an argument.  Now, I'm thinking that the site's really nifty, and I should definitely notify my classes.  It's late, so I decide again to wait. 
    By morning, maybe half a dozen more people have responded.  How great that students will be able to learn from strangers as well as each other.  This is the power of the web.  One German-born person filled in some interesting historical facts.  Some arguments are stronger than others, but students would have the chance to vote for the ones they think are strongest.  Then I come to a response which includes a word that would not be acceptable in a thesis essay.  I'm crestfallen.
    I go to class and, to the delight of my students, tell this story.  They became animated and alert.  They immediately try convince me that they should be allowed to use the site.  (I mentioned how much they love to debate, right?)  They also want to know the offending word which is preventing them from debating on-line.  I decline to tell, so they start to guess.  They shout, "Is it 'I'?"  I love this response because A) apparently they've learned not to write "I" in a formal essay, and B) they're naive enough to think this is the word that's troubling me.  On the other hand, they then proceed to tell me about the rated R movie they are looking forward to seeing this weekend.

     What do you think?  Do the benefits of this site outweigh the costs?  Should seventh grade public school students be allowed to use this site?

Everybody has his or her preference.  What's yours?

The ADDIE model provides a formal, structured framework for the development of instructional interventions. To the best of my knowledge the model has its origins in the American military, but has been promoted widely, particularly as a basis for the design and development of self-paced e-learning. ADDIE (Analysis, Design, Development, Implementation and Evaluation) has been criticised because of its rigidity, its waterfall-like flow (down but never back up) and because hardly anyone really uses it in practice. On the other hand, alternative models (or the use of no model at all) can be accused of being too fluid and potentially wasteful. So, is it time we kicked ADDIE into touch, or is the problem that we haven't been taking it seriously enough?

Online learning has it advocates and its opponents.  In order to understand the issues, it is important to examine the pros and cons of this type of learning.  Please add to both sides of the debate. 

Some are good, some are bad. What makes you choose to read or ignore them? How can they be improved? What do you like most/least?
