First Published in 1982. This is Volume 1 of a series on Writing, the nature, development and teaching of written communication and focuses on Variation in Writing: Functional and linguistic-Cultural Differences. The theme of these two volumes, broadly defined, might best be phrased as two questions: How can we learn more about writing? and How can we learn more about the interaction between teaching to write and learning to write? The papers in these two volumes were originally prepared in draft form for the National Institute of Education's first Conference on Writing in June, 1977.
