Read the work before the score
Open the submission with the activity requirements in mind. Identify what the student has understood and what needs another attempt before reducing the work to a number.
Point to something specific
Use comments or document annotations to connect feedback to a sentence, diagram, or calculation. A concrete reference is easier for the student to act on than a general instruction to improve.
Name the next step
Explain one useful action: add evidence, revise the comparison, or show an intermediate calculation. Feedback becomes more helpful when it gives the learner a starting point.
Save deliberately
Confirm the grade and save PDF annotations before moving to another student. Keep the review loop clear: read, respond, save, and then continue.
