Extra white space may be used to separate major sections. Some care needs to be taken with the style of heads and lists. They need to be consistent and parallel. If, for example, you choose to use bold and all caps for your maajor heads, then all your major heads need to be bold and all caps. That is consistency.
Parallelism is the similarity of grammatical structure among heads or items in a list.
Parallelism need not be absolutely exact. So keep primarily to professional details, but a course is also a collection of people, so some personal background and explanation are also quite acceptable. The first section of a business or technical document is introductory and is geared to the needs of the audience. Memorize these four requisites of an introduction. They should be present in all your introductions this term.
