A new course entered for the first time will be mostly blank. Course templates have block areas on the left and right sides, with course Activity modules and Resources grouped by sections to fit your needs.
Generally speaking, the first or top section is not numbered and was designed for general information and to contain activities and resources useful during the course. Most courses will have at least one additional section.
The view of your course homepage depends on which block areas you choose to appear using the Blocks field. All of the blocks can be shifted around according to one's liking, due to which the view of the course homepage may differ.
Standard view of a blank course
In Moodle 1.6 and above, a site may allow its teachers to use color themes that are different from the Moodle site homepage.
The site administrator must go Administration>Configuration>Variables and change the allowcoursethemes to yes. Then teachers will see the new property at the bottom of course settings called Force theme, with a drop down menu of different available themes. Non-editing teacher can not alter this setting. The default course theme is the site theme.
Drag and drop
Be aware that drag and drop for course sections currently (25th Feb 2008) has an issue and only support dragging a course section onto an adjacent section. Fix on the way: MDL-11539
