It is a big mistake to expect newcomers will edit as experienced editors, when the newcomers know nothing about creating a new WP-article.
I suggest encouriging them to correct small mistakes, typos and such in existing articles to gain experience first, and much-much later they will start a new article by themselves.
Maybe also would be good if they would point to mistakes in articles, or suggest corrections.
Many times we notice that they leave a message somewhere in Help forums with a suggestion about an article (which contains errors), but they do not know how to correct this and ask editors for help. Maybe this is also not an easy task for a newcomer.
