In this article, Albert Wolfe of Laowai Chinese talks about handwriting as the fifth skill. The four normal skills are listening, speaking, reading and writing, but he argues that in Chinese, handwriting isn't really part of the writing skill like it is in other languages. Instead, it should be considered a fifth skill. He also talks about the difference between writing by hand and typing, and what consequences this has for learners and teachers. Overall a very thoughtful article well worth reading.
