What aspect of writing does the teacher address during proofreading of student drafts?

During proofreading, the focus is primarily on the use of conventions, which refers to the mechanics of writing, such as spelling, punctuation, grammar, and formatting. These elements are essential for ensuring that a written piece is clear and understandable to the reader. Proofreading involves carefully reviewing the text to identify and correct any errors that may detract from the writing's professionalism and readability.

While aspects like word choice, clarity of ideas, and overall length are important parts of the writing process, they are typically addressed in earlier stages, such as drafting and revision. The proofreading stage is specifically concerned with the final polishing of the draft, ensuring that all conventions of writing are correctly applied to enhance the overall presentation and effectiveness of the work.
