I'm applying to Columbia's journalism school and it asked me if I have any publications. Since I worked as a reporter before for the local newspaper, and I did write a few headline stories, I thought this might help my journalism application. But since they're nor academic, I'm not sure if I should put down my news articles as "publications."
It's not uncommon to have subheadings for different kinds of publications. "Peer-reviewed journal articles", "Proceedings", "Monographs" and so on. For a journalism program, "Newspaper articles" seems like a completely appropriate subheading.
If that's a school which teaches journalism, then definitely, but like @rturnbull suggests, list them separately from anything else, since they're not academic publications about journalism.
If it's a graduate program for the study of journalism, then possibly, but only to a minor extent - and still it's the same practical advice: List them separately from anything else.
