You may notice a different course home page default in Winter 2018 Canvas course sites.
Previously, the "Recent Activity" view was the starting place for your course site design, though many instructors would change the Home Page to Modules, a Front Page, or the Syllabus view. Now, the course home page defaults to the Modules view with the module tool ready to use. A new "Add Existing Content" button is provided to take instructors directly to the Copy a Canvas Course feature.
You are not required to use Modules for the home page or for your course site design. You can set the course home page to your usual setting as part of your course copy from a prior term or by clicking Choose Home Page from your sidebar. You might be prompted to choose a home page when publishing your course if you have not already done so.
