What feature allows students to receive personalized feedback through Google Docs?

The feature that allows students to receive personalized feedback in Google Docs is the ability to add comments. Comments enable teachers and peers to provide specific, context-driven feedback right within the document. When a comment is added, it can directly reference the related text, making it easier for students to understand the feedback in context. Additionally, comments can be resolved once the feedback has been implemented, allowing for a clear tracking of changes and suggestions. This interactive dynamic fosters an environment where students can engage with feedback, ask questions, and have a dialogue about their work, which significantly enhances their learning experience.

While form responses relate to feedback gathered through Google Forms, document sharing allows collaboration but does not specifically facilitate feedback. File uploads are primarily about attaching files rather than interacting within a document for feedback purposes. Thus, comments stand out as the most effective means for personalized engagement.
