Rh SUMMARY

On p. 135, we pictured the writing of language textbooks as a flow chart, and the process as a linear one. Seen in another way, the same activities we have described in this chapter are concentric: each successive procedure establishes a nucleus around which to fit what may be produced by later procedures. Writers of lessons may provide one layer of inner structure, or many. It would be a mistake, however, for them to assume that they can supply the final outer layer; only the users of the lessons can do that.

The remaining chapters of this book are about devices that we have mentioned as particularly useful in adapting materials or in making them adaptable: learners' synopses, Cummings devices, one kind of sample of language in use, and routine drills.
