There’s a fair amount of research, which I describe in some of my books, which shows that leaving lots of teacher comments on student papers is pretty much a waste of time — many, if not most, students don’t pay much attention to them. And doing that with our many students who are struggling writers can be very damaging and deflating (one of the many reasons I don’t like the idea of computer grading of essays). Instead, what my colleagues and I try to do is generally focus on one major positive area and one area that needs improvement (usually via post-it note and quick private conference) and teacher short class lessons on what we see as common problems — sometimes through the concept attainment method.
However, for our International Baccalaureate classes (in particular, for the Theory of Knowledge course I teach), we have some very self-motivated students that have to develop essays that are submitted to IB, who can be pretty particular. Even though we are constrained by IB rules about the number of times we can provide critical feedback on outlines and essays, we need to be pretty complete during the times allowed.
For those classes, I can see the 121Writing site as fairly useful. Students log-on to your class site, copy and paste their assignment onto it, and teachers can provide audio feedback on it. It could save a teacher time, and provide a way to give more detailed feedback to students who need it, and can “take” it.
I learned about it from Richard Byrne’s blog, and I’d encourage you to visit his post to read more about it. His post focuses on schools using Google Drive. However, you can use it even without using Google Drive by registering at the site here.
I’m adding it to The Best Websites For K-12 Writing Instruction/Reinforcement.
