Finding the Balance

I don't know if anyone else has thought about this, but my grading and comments on papers have changed significantly. When we first began grading essays in class, I would read through essays and mark every gramatical error I could find. I focused on the mechanical side of students writing. But as I finished up my final set of essays, I noticed that I was focusing on the content of the paper. Most of my changes and comments revolved around paragraphing, theses, etc. Now what i need to work on is balancing out my comments. I feel that it is important that students improve on both grammar and content. They are equally important. I think the balance is something I will achieve over time and with practice.
