Instructors may use Canvas Modules to structure their course and organize content and activities. Think of the course as a filing system, where the course shell is the file cabinet. Inside the filing cabinet are manila folders. Modules are the manila folders of a Canvas course. The are ready to keep thematically like materials, readings, activities, and assignments together as a unit.
D2L Modules
D2L also uses a Modules as the most common method to organize the course. These are created in the Table of Contents or the Course Builder Tool. The Modules are populated in those tools as well.
What to Expect when Converting from D2L to Canvas:
D2L Modules as well as the D2L files within those modules convert from D2L to Canvas intact for the most part, however instructors should always check as they are two different systems with two different structures. Release conditions at the module or assignment level will not covert. Due dates will convert for the most part.
