Sandpit

1 Sandpit instructions

The purpose of the Sandpit is to provide sample file for you to use to explore the database and moderation features of ReMarksPDF. The Sandpit zip file consists of:
• 62 marked files – 20 files marked by three different markers.
• Marker 1’s distribution of marks is positively skewed
• Marker 2’s distribution of marks is negatively skewed
• Marker 3’s distribution of marks is bimodal – low and high
• Sandpit template for you to create more files
• Sandpit.csv – a database for the 62 students with columns for Student No, Student name and Email
• Sandpit.rzip - a sharefile containing marking criteria

Fig 7 Database pane

You will notice that ReMarksPDF will automatically link the database with the associated student files in the Sandpit folder. Green files are marked. Red files represent students who have not submitted an assessment for marking. Black files are submitted unmarked assessment.

3 Moderation

To moderate the files select the Moderate pane. To view the marking of each of the three markers, select Marker 1 and click on the All Students. Click Add detail and make the same selection for Marker 2 and repeat for Marker C. To view the Grade Report, select Actions> Grade Chart (Fig 8).

In the sandpit files, you can see that Marker 1 is positively skewed (low marks), Marker 2 is negatively skewed (high marks) and Marker 3, is bimodal with a cluster of high and low marks. This is a situation where moderation should be considered to introduce fairness into the marking process.
