Use the appropriate walk-through form (under "Assessor Record Sheets" on the DiDA Documents page) to keep an ongoing record of a student's performance and provide formative feedback during the project.
When the project is complete, fill in an ARS for each student, recording the mark they have achieved for each strand and their overall unit mark (out of 42). Check your arithmetic!
The ARS is an invaluable source of information for the moderator. Use the comment boxes to explain why you have awarded a particular mark if this is not obvious and/or where relevant evidence can be found in the eportfolio.
