On Moodle, the course material is either a resource or an activity.
A resource is an item that the student views, listens to, reads, or downloads. Examples include a web page, a link to another location on the Web, a file that the student downloads and a video that the student watches.
An activity is an item that the student interacts with, or one that enables the student to interact with the teacher or other students. Examples include a quiz, an assignment that the student uploads for the teacher to review, a wiki and a forum.
Usually, resources are ungraded while activities are graded.
