Does the current work situation in the seminar require a practical example to make the problem visible? A role play, an exercise, or a structured experience that allows participants to experience attitudes and impacts? In such situations, the work catalog is an indispensable lexicon for group and seminar leaders, trainers, and therapists. A decision tree quickly leads to the desired issue, and the exercises are then described in bullet points with time indications, objectives, content, etc. Over 1,200 such exercises and games are lexically recorded. References to the original sources allow for quick access to necessary participant materials, evaluation materials, or more detailed information. The new 7th edition has been made even clearer, updated, and combines the previous volumes 1 and 2 into a single one. A must-have.
