Using simulations in a class on international organizations is a wonderful way to provide students with hands-on experience and deepen their engagement. Taking on different roles through simulations can be exciting for students. Another benefit stems from the availability of artificial intelligence tools that are changing learning, so incorporating role-play exercises gives students a genuine experience, and instructors can be confident that the students are responsible for their own learning. With so many design possibilities, determining the first steps for incorporating simulations in the classroom can be difficult. The chapter begins by addressing the basic aspects to consider before introducing a simulation in class, before highlighting some of the “out-of-the-box” possibilities for incorporating simulations and taking a deeper dive into how instructors can design customized simulations. The chapter concludes with a discussion of how to integrate this learning exercise through debriefing and assessment. © The Editor and Contributors Severally 2025. All rights reserved.
