ePortfolio items that users submit to a dropbox folder are treated as unique objects; they do not change when the original item changes. This allows you to assess or grade submissions without worrying about users revising their work.
Dropbox folders can be associated with a competency or a grade book item in Learning Environment. You can also attach feedback or comments to specific submissions.
Tip If you select the Allow users to add this folder to their ePortfolio option with a dropbox folder's properties, users can add their submissions with your feedback to their ePortfolios. This allows users to continue improving their work, while maintaining a copy of how the item appeared at the time of assessment.
