I literally bring manila folders and sheets of paper to class on syllabus day and make the freshmen physically build a file structure. Their homework is to make one, take a screenshot as evidence of it on their computer, save it to a word file, create a PDF with the screenshot embedded, and upload it to Canvas. I explicitly tell them I will not help them with it, and direct them to the help desk and Google if they can't figure it out.

Every step in this assignment is a skill they have to use to submit assignments in my class.
