Teachers and admins can access reports on discussions. Reports can be accessed for the course in the Comments Box course navigation item or for a specific discussion by clicking on the chart icon in the upper right of a discussion.
The report will show information about each student enrolled in the course and the number of comments they have added to the discussion. You can search for a student's name to narrow down results.
You can export a .csv or a .pdf file of the discussion reports by clicking on the three dot menu in the upper right of the reports page.
The course reports page allows you to filter the reports by the Canvas modules they are embedded in. If a discussion does not belong to a module it will show in the Entire Course filter. Clicking on the histogram will direct you to that discussion’s report.
