Thanks for the comment. The course catalog is the official record of course descriptions for students to read before registering for classes, and will provide the main themes and a general overview of each course. Click on "View Catalog Entry" to see the course description.
Making Moodle courses available for potential students to see syllabi is not possible for a number of reasons, including the fact that not all professors and instructors use Moodle, and also because the course materials may not yet be updated for the new semester in time for registration.
I'd recommend asking individual professors for more information about a course you would like to take!
