an ordinary chessplayer makes the point more effectively than I did. But my suggestion was that the coach should recommend a move as well as, not instead of, explaining the reasons for that recommendation. If the student understands the reasons then he/she could of course make his/her own choice. But if the student wants a recommendation I believe it does no harm, and can be helpful, for the coach to make one.
That is what I said I would do.
When TopNotch recommended the Socratic method, I think he meant to use questions to lead the student to the place you want him to find. In the original, this can appear quite strange. "Now are we agreed that if the wind blows, it therefore does not suck?" --"But of course, Socrates, how could it be otherwise?" "And if a thing does not suck, would you say that thing could be bad?" "Of course not, for if it were bad, it would also suck." "Then what do you think, is the wind, which after all the gods direct, good or bad?" "It would seem it must be good, Socrates." When Plato is the writer, of course, it will have more levels than meet the eye.
Anyway, I propose having in mind the moves 2.d4, 3.Nc3 from the beginning, but delivering them in such a way as to teach the student how to think once out of book and to demystify the process. Note that at the end,
based on knowledge, 4.exd5 is recommended, even against the earlier thinking. So the student is given a recommendation of "repertoire" moves, but the main thing is that he is taught how to work out opening moves for himself and never to stop thinking. I don't think the book move itself does that much good in the end at this level.
Turning a man into a fish is a joke which must be watered down. Of course it does no harm and can help a little to just give him some moves, as it does no harm, and may increase his interest and pleasure, to teach him the history of chess and show him the original Staunton pieces. But if after their second game our 1100 opponent undertakes to prepare 16 moves of French Exchange Variation theory while our 1100 student continues learning to think, then I believe that three months later our now-1140 student will beat our now-1105 opponent in a match.

Thanks for a nice list of opening principles!
