There are several models - the one Cup of Joe refers to is an extenstion of the VARK model, which actually deals with how we prefer to take in information, rather than how we learn doing so - but the better we take in information, the more likely it is to have an impact on the effectiveness of the learning.
The pragmatic comes from a different model, called the Honey-Mumford (there are more nuanced models out there. but this is one of the most widely used) which deals with how a person learns in terms of what they do with the information. There are activists, pragmatists, theorists and reflectors. In the case of pragmatists, they learn strongly by doing things, trying learning out and seeing where it takes them. It's why I occasionally get narky when writing books are seen as a great way for everyone to learn - they are, but most effectively by theorists and reflectors (who can learn any way - it's about having time to reflect so that the activity has become embedded). Pragmatists might read a writing book - but they'll only learn from it by actually writing and trying its concepts out.
So, yeah, learning through writing is a pragmatist's preferred learning methodology. It's why I haunted the critiques board here in my early days.
