Educators often address presentation ideas for composition courses by focusing their efforts on a specific discourse community -- legal, academic, law-enforcement or even political, for example. The audience you want to address is of paramount importance. Many experts regard composition courses as a proverbial "gateway" into a perspective of already understood cultural or professional premises. For example, when engineers present information, in most circumstances, they do it to others in the corresponding field. They generally have similar vocabulary or common background. You can use this idea to tailor classroom instruction accordingly.
Writing and composition are often actually regarded as two different entities. When presenting any ideas regarding composition to a group, address the fact that composition is probably more than just the act of putting a batch of signs on paper. It is also most likely beyond arranging those collections of symbols in a group. Different rules and conventions are meaningful in different ways to different groups. Try talking about how this may apply between professions, for example.
Some experts regard composition courses as an exercise to promote the use of writing. Whether it be for personal or professional reasons, consider this among one of many presentation ideas. It may be effective to first present the idea about how composition, or at least according to some, is simply a group of social or even cultural practices. You could even extend this premise to address how composition may or may not consider the viability of certain communities in contrast to others. Talk about who gets to make the writing "rules" or practices that others should follow, for example.
Composition courses often require students to emulate or even model other authors. Presentation ideas for composition courses could entail in what ways this idea is either correct or even incorrect. Someone who is a grant writer, in all likelihood, may not be a successful novel writer, for example. You can present how your particular instruction allies with this premise.
