At my school, computer animation focused on 3D animations, with students leaving the course(s) having made a short 3D animation. Chico State may be different, it simply depends on what the instructor decides to teach. If you can find a description of the courses, that might help clear things up. I've always found emailing the instructors (if you can find them) can help clarify things as well.
The thing is, depending on who you talk to, computer animation could cover quite a few topics. 2D cartoons, like South Park, extensively use computers. It could also describe Pixar movies where they are completely computer generated graphics. There are also special effects that are added to enhance live action footage. Then you could have a mix of all three or something else I have forgotten to mention.
If I were you, I'll definitely try to find out what exactly is taught in the classes first. My school only had a single series of three courses dedicated to computer graphics tucked away in the computer science department. If you are serious about doing animation, you may want to check out an art school, which should have all the classes you could want for different kinds of animating.
