“…It has been documented that some types of humor used by teachers in a classroom setting—such as humor related to the course content, humor directed at oneself, and humor not involving aggression against others—has social functions. These functions include the building of good relationships with students and creating a positive climate (e.g., Aylor & Oppliger, 2003; Claus et al., 2012; Sidelinger, 2014; Tsukawaki et al., 2020), in addition to educational functions, such as increasing the motivation for learning and promoting the understanding of class content (e.g., Bieg et al., 2017, 2019; Bieg & Dresel, 2018; Tsukawaki & Imura, 2020). Teachers’ adaptive humor is also thought to improve students’ mental health (Lei et al., 2010; Ziyaeemehr et al., 2011).…”
