As you apply that skill set in your real world, you'll augment and expand it. Interaction varies greatly depending on the student. Some students just send in their assignments and we never hear anything else from them. Others ask all kinds of questions and we do our best to answer them. Sometimes, when we travel, we get together with our students in person.
Interaction also depends on the number in a class.
Our faculty is as good as the faculty at any land-locked institution. I know because I personally selected every one of them. They are experienced teachers and writers who know their material and know how to teach it.

In my undergraduate days, I worked in the foreign student office of San Jose State University.
