If you have students turn in homework assignments via the dropbox and want them to see the solution after they submit, there are a couple of ways to do this:
Give the students the homework solution file as part of the feedback for the assignment. On the Leave Feedback page there is a button Add a File that you can click to add a file from your local computer that will only be visible to that student. You could wait to provide feedback to students until after the assignment is due if you are concerned about the early submitters sharing the solution file with their classmates.
Another option is to include the file as part of the grade item for that dropbox folder instead of as part of the dropbox folder feedback. This allows you to control exactly when the file appears; you may want to let students know in the Custom Instructions field for the dropbox folder where and when the solutions file will appear.. First, upload the file to your Manage Files area:
- Click Edit Course on the navbar.
- Click Manage Files and then click Upload
- In the window that opens, click Browse to find your homework solutions file and then click Upload
Now your file is ready to be quicklinked from the grades area:
- On the Grades page, click the Manage Grades button
- Click on the Enter Grades icon for the item associated with the dropbox folder
- Click Show details and overall comments
- In the Overall Comments box, insert a quicklink to the course file you uploaded above - don't forget to click Save
If you do not want students to see the solutions file until after the assignment is due, you can make the grade item appear at that time:
- While on the Manage Grades page, click on the name of the grade item associated with the dropbox folder to edit it
- Select the Restrictions tab and choose a Start Date for the item's visibility - don't forget to click Save
A third option is to create a content topic that includes the homework solution and set the availability date for that item to take place after the assignment due date. As with the option to attach it to a grade item, you may want to let students know in the Custom Instructions field for the dropbox folder where and when the solutions file will appear.
Finally, you can use release conditions to display the homework solution automatically as soon as students receive feedback from you. One of the condition types is "Receive Feedback on Dropbox Folder." You can create a release condition using this type (D2L will prompt you to select a dropbox folder) and limit the content topic to students who meet this criterion.
