You handle setting up your online course. Why you? Because you are the one who has to teach utilizing this setup, and the process of setting up the course will help you become familiar with the environment you are going to teach in. Although you may have technical fears as you build your online course, it is important that you know how your course is structured online, and how it will work. It is also important to realize that the teaching development team at the Teaching Centre is here to help you at every step of the process, from establishing student learning outcomes, to helping you understand how to import your questions into question banks for your online quizzes. Contact us with any questions you may have. You can come to your office, we can come to yours, or we can connect online using a variety of tools (which is also an excellent way to see how they work).
If you have Moodle specific questions, you may be able to find the answer to your question at http://moodleanswers.com
