This is class one of an online course I've been teaching to our high school students. It's been great, as we've seen a 600% increase in participation vs. when we used to ask them to come to class in person.

The process is pretty simple. They watch the class. Answer a few questions. Email me the answers or hand them in at Mass. I record that they did it.
If they don't participate, that's fine - the Church says the primary catechist of a child is their parents, so I assume the parents are doing something else to teach them the Faith.
It's been great. Hope these help. I will post them here occasionally. Here's class 1
