This tool will allow you to get all the submissions associated with a single Canvas assignment and perform a grader analysis to determine if any of your graders have awarded marks that are significantly lower or higher than the global median score.
The tool also generates a .docx file containing a summary of the numbers of submissions that have been awarded each classification (fail, pass, 2.2, 2.1, first class), identifying those that are borderline. The report contains detailed boxplots for the grader analysis and also a grader feedback analysis based on word counts provided in annotations and submission comments.
This tool will really help me speed up my moderation for large, complicated Canvas assignments and improve student experience by reducing the time taken to release grades/feedback and improving grader consistency.
