Once students submit an experiment, they cannot edit any answers in the lesson. Instructors may choose to unlock the lesson for editing and resubmittal if they choose.
To unlock an experiment, log onto the LabTutor Server as administrator. Click on the Student Data tab on the left side of window, and then click on Find and Manage. You may then select Status and Allow Resubmit to unlock the student data or Delete to delete all data for this student experiment.
Once you click on Allow Resubmit you will see the following screen showing Status as "In Progress".
If you choose Delete you will be given two chances, as shown below, to confirm deletion of the student data for this experiment.
