In terms of an english class, blogging is a way to practice skills that you have learned and show that you know how to use them without a boring worksheet. It is your own ideas and changes as you go, which is really important when teaching people to be their own writers and not use a typical writing format. I think this is a good way for teachers and students to know where they stand in a class, performance wise. I also like that when you get stuck with an entry you can look at blogs of other classmates or simply other blogs on the internet to come up with new ideas or ways to say something. For as much as I enjoyed writing blogs,I enjoyed reading other people's even more.
For myself as a student, blogging helped me realize that I need to focus on digging deeper with my information when I write. For as long as I can remember, I could BS a paper and focus more on how I was saying something rather than what I was actually saying. I have always been a wordy person and this pushed me to make my words say something instead of sounding good. This is an important lesson in writing that every student goes through at some point in their schooling. These blogs can really help you develop and grow as an author and thinker, if you take them seriously.
When taking this class, don't be afraid of the work load. It can be done. Don't be afraid of the papers, they will get better as the semester goes on. Don't be afraid of the blogs. You will have a love/hate relationship with them.
