This is #6, the last, of this six-part series on "Missiology You Need to Know." The simple concept is that the means, methods, and tools/resources that the missionary uses must be reproducible by his audience. The content of the teaching and training has to be able to be replicated by the local people. So, don't use things that are inaccessible to them! Find out how they would do things if it were up to them and/or if the missionary wasn't present to do it.
