Several of my courses have material open to the public as well as my students:

Perspectives on Women: https://blogs.stockton.edu/perspectives/

Literary Methodologies: https://blogs.stockton.edu/litmeth/

American Popular Culture and Folklife: https://blogs.stockton.edu/ampopculturefolklife/
I also use Blackboard (a course management system open only to registered students) in all of my classes.
