I created a blog while I took a week long trip to Germany, so that my students could keep up with my travels. The blog was especially interesting to them because they are studying German with me. I could tell all of these stories when I got back, but they said it was exciting to them to read about it as it happened. I think blogging while traveling could be especially useful for extended travels, or for keeping contact with a penpal or partner school. 

My favorite part was adding photos!
