Excellent effort, Louis! Thank you.. I really want to learn to speak, write, and think in Ancient Greek. I hope more and more teachers revive this language. Thank you for all your hard work.
I know you're more interested in TPRS for teaching ancient Greek, but I wanted to add in a couple links and info on some pre-TPRS guys. (Rico you already mentioned).
1) Karl A P Ruck created a book and an "experimental method" which (IMHO as one who prefers immersive/inductive language learning) doesn't get nearly enough reviews even here on textkit: "Ancient Greek: A New Approach" which was highly oral/aural, though pre-TPRS. First (1968) and revised (1972) editions were supposedly more oral/aural than 2nd edition (1979). It did require a teacher, speaking and drilling students. His point (quite well taken, and of course used later by TPRS) was that grammar should be learned inductively, not memorized through tables. He wanted students to produce
(i.e., be able to speak and write and manipulate the language automatically). Quite fittingly, this is exactly how the ancient Hellenes thought about learning -- you don't "know" something until you can DO it. Like riding a bike. (As opposed to what we moderns think, an "academic" idea of learning, which is that we've learned something once we've memorized some "facts" and can regurgitate them on a test.) The 2nd edition of the book is still in print, but again the aural/oral was slightly de-emphasized. 1st edition can still be found in some libraries. It was teaching Attic. 1972 edition was ISBN 0-262-18047-2 (hardcover) or 0-262-68016-5 (paperback). 2nd edition is only available in paperback, ISBN-10: 0262680319 or ISBN-13: 978-0262680318, amazon: http://www.amazon.com/Ancient-Greek-Carl-P-Ruck/dp/0262680319
2) Christophe Rico has had a book out since I think 2009, which he uses (along with other materials and activities) to teach Koine courses in Jerusalem and around the world, using TPR(S) and website is here, along with a sample chapter, and 1 classroom video: http://poliskoine.com/site/
and more of his videos here: http://www.youtube.com/user/poliskoine/videos
The book is in French (but very little French is in it -- mostly Greek). Also, it is not cheap, but is available in Europe on fnac.com ($60USD + shipping, at http://livre.fnac.com/a2415875/Christophe-Rico-Polis-parler-le-grec-ancien-comme-une-langue-vivante
..and on amazon.ca it is published under the title of "Parler le Grec Ancien Comme une Langue Vivante" (about $112USD) at http://www.amazon.ca/dp/2204087572
In the videos he appears to be using more TPR (i.e. purely physical) than TPRS. Could ask him if he's added TPRS these days..
