“Training from the BACK of the room” had already been helpful to me for more than three years. Although a lot of the material was already known to me, I gained a new level of insight in the various ideas behind the approach introduced in Training from the back of the room.
Regardless of your experience, I would recommend this training to anyone that has to teach people new ideas. For experienced trainers, the workshop is humbling in the sense that you experience what your learners experience in your class.
Perhaps some would characterize certain activities as childish but they are fun and engaging too. Still, childish beats boring and dreadful as experienced in mosts training sessions. In short: join the class!
