Re: Teaching the names of techniques.
I found it helped to have a book with step-by-step pictures of the techniques, including the names, which I compared to what we had done in class. Of course, you can't learn from a book, but it really helps with the names, besides it's often easier to see foreign words in writing rather than just hearing them.
We are also given a list of techniques which we have to know for the exams, so we can always ask an instructor if we've still not familiar with a certain technique.
Christian Tissier Sensei's book, A´kido, is the most useful to us because we follow his style and the techniques, with the attacks, are in the order of the kyu-grading.
