So, thinking out loud again, here's how I'd start planning my course.
Decide on the Subject
The first step is to decide what to study - creative writing is a big field, after all. You might want to write children's novels, crime thrillers, or how-to books, or get started in poetry or article writing. Picking a subject at this point will help you to keep focussed on what it is you want to achieve.
Let's say you want to write crime fiction - do you want to write cosy mysteries or Tartan Noir? Are you interested in the history of the genre, or historical crime fiction? Picking out areas of interest will help later when it comes to choosing specific texts to study. Write a list, do a mind map, or whatever helps you get the ideas down.
Choose Modules
Taught courses tend to be divided into modules, which is a good way of breaking it down into manageable chunks. Sticking with crime fiction for a moment, if you've read it but never written it, you might decide to spend some time reading books about how to write crime and thrillers. You could include a module on the type of crime fiction you've decided to write, and other writers in that area. For example, if sticking to the grittier end of things, you could include some Tartan Noir, Scandinavian crime novels, or dark crime fiction written by women. If writing for children, you could look at books for that age group, and the particular genre you want to write in.
You can also include modules that fit around the subject - for example for crime fiction there's forensics, psychology, weapons. There are plenty of books out there of the "guns for writers" variety, which could be a useful resource. It depends on where you want to build up your knowledge.
Pick a Final Project
Most MAs have a final project as the end goal, for example a novel or a poetry collection. What do you want to have achieved at the end?
Next time, we'll fill those modules with content.
