This document discusses the Natural Approach method for teaching second languages. It was developed in 1977 by Tracy Terrel and Stephen Krashen. The key principles are that comprehension precedes production, production emerges gradually, and activities are communicative. The method uses techniques like total physical response commands, visual aids, and pictures to teach vocabulary and concepts before students produce language. The advantages are that it is easy to use and reliable, but the disadvantages are that it takes a long time and does not focus on correctness.
