Read: Leading Dynamic Seminars
It is only practical in the sense that it does not fall in the Pure Theory category. It is, however, rather generic and in an attempt to avoid describing specific tools that may not be available in the future it avoids describing any practical implementations at all. No, that is wrong. It is offering some specific phrases the seminar leader should avoid or use for obtaining the best results, taking care of the potential diversity of his seminar participants. I do not think anyone should learn these specific phrases in order to repeat them in the seminar room.
Bottom line is the little handbook was a bit of a downer. The authors define their audience in the beginning of their text rather broad, from the novice teacher to the seasoned department chair and university administrator. That definition is too broad. The generic directions are of use mainly for the novice. After only a few years of teaching all the mentioned points should be obvious and intuitively part of the seminar leader’s repertoire.
