In teaching practice, we can meet challenging participants who disrupt group work. Whether it's those who don't respect boundaries, don't respond, repeatedly reject, or embarrass the experiences of others. Such situations are challenging for all three sides—participant, group, and lecturer. Breathe, there is a way to deal with it. You need to keep a safe space and don't judge. Success in working with challenging participants lies in the combination of the lecturer's attentiveness, empathy, and effective communication. On this journey, you are going to get a mix of knowledge and practice in model situations, where you have the opportunity to constantly try new approaches and find those that work for you. And last but not least, we are going to work with the typology of the most frequently challenging participants, composed in cooperation with fellow highly experienced lecturers of applied improvisation.
