I found a site where students can create comics. This site can be used in a few different languages.
I created a comic quickly. You can pick from a variety of characters. There are different images you can add to your comic. Your comic can be up to 4 different boxes. This site does not save comics, so students will need to print as soon as they are finished. You can email comics though, so students can print later if they don't have access to a printer.
Here is a link to what I created: http://www.makebeliefscomix.com/Comix/?comix_id=34864482C912234
Here is a screenshot of what I created:
I found this site to be a little complicated at times. When adding the speech bubbles, you can not change the size after you pick which one you want to use. I found that to be pretty frustrating because the default size covered most of the box.
So far, this is not a web2.0 tool I would recommend because I think there are better ones out there. I will see what I can find.
