When humour harms: Teacher humour and the development of students’ psychological well-being
This longitudinal multilevel study of German ninth-graders reveals that teacher humour is not universally beneficial, as aggressive and course-unrelated humour negatively impact students' psychological well-being, while course-related and self-disparaging humour show no reliable long-term benefits.

The Classroom Comedy Club: When Laughter Helps and When It Hurts
Imagine the classroom as a giant, shared living room where learning happens. In this room, the teacher is the host, and the students are the guests. For decades, scientists studying human behavior have known that humor is a powerful tool. It's like a social glue that can stick people together, or a sharp knife that can cut them apart. Psychologists have long categorized humor into different "flavors": some are friendly and build bridges (like telling a joke about a shared struggle), while others are mean-spirited and build walls (like making fun of someone's appearance). We also know that how we feel about school—our "psychological well-being"—isn't just about getting good grades. It's about whether we feel happy, safe, and excited to show up, or whether we feel worried, lonely, and dread the bell.
But here's the big question: Does a teacher cracking a joke actually make students feel better about school in the long run? Or could the wrong kind of joke actually make things worse? This isn't just about whether a class feels "fun" for an hour; it's about whether the teacher's sense of humor shapes a student's mental health over an entire school year. While we know humor is complex, we haven't really known which specific types of teacher jokes help students thrive and which ones might secretly be dragging their spirits down.
The Study: Tracking Jokes and Feelings Over a Year
This paper dives into that mystery by following a massive group of 1,273 ninth-grade students in Germany across one full school year. The researchers didn't just ask, "Do you like your teacher?" They asked the students to rate four specific types of humor they saw in their English classes:
- Course-related humor: Jokes that actually connect to the lesson (like a pun about grammar).
- Course-unrelated humor: Jokes that have nothing to do with the lesson (like a random dad joke).
- Self-disparaging humor: The teacher making fun of themselves.
- Aggressive humor: The teacher making fun of students or their private lives.
The team measured how the students felt at the start of the year and again at the end, looking at four key feelings: Do they have a positive attitude toward school? Do they enjoy being there? Do they have fewer worries? And do they have fewer social problems with classmates?
The Findings: Not All Laughs Are Created Equal
The results were a bit of a surprise to the "humor is always good" crowd. The study suggests that teacher humor is not a magic bullet that automatically makes students happier. In fact, the type of joke matters more than the fact that a joke was told at all.
The "Mean" Jokes Are a Real Problem
The most consistent finding was about aggressive humor. When teachers made jokes that ridiculed students or their personal lives, it was like pouring salt on a wound. The study found that this type of humor predicted a clear drop in how much students liked school and how much they enjoyed being there. This happened whether you looked at the class as a whole or at individual students. It suggests that when a teacher uses humor to punch down, it threatens a student's sense of safety and respect, making them feel less positive about school overall.
The "Off-Topic" Jokes Might Be Distracting
What about the jokes that have nothing to do with the lesson? The study found that course-unrelated humor didn't help students feel better; in fact, it was linked to more worries over time. It's as if the joke pulled the students' attention away from the structure of the class, leaving them feeling a bit unsettled or anxious rather than relaxed.
The "Safe" Jokes Didn't Change Much
Here is where it gets interesting. You might think that jokes about the lesson itself (course-related humor) or the teacher making fun of themselves (self-disparaging humor) would be the heroes of the story. However, the study suggests these types of humor did not reliably boost students' well-being over the long haul. While they might be nice in the moment, they didn't seem to be the secret sauce that transformed a student's entire year of happiness. They weren't harmful, but they weren't the powerful boosters many hoped for.
The Takeaway
The main message from this research is that we need to stop treating all teacher humor as a "good thing." It's not a simple switch that turns on happiness. Instead, humor is like a spice: the right kind can make a meal delicious, but the wrong kind can ruin it.
The study strongly suggests that teachers should avoid humor that targets students or makes them feel small, as this actively harms their psychological well-being. While making jokes about the lesson or poking fun at oneself is harmless, it doesn't necessarily fix deep-seated feelings of worry or unhappiness. Ultimately, for humor to truly support a student's mental health, it needs to be kind, inclusive, and safe. If a joke makes a student feel unsafe or anxious, it's not a joke at all—it's a barrier to learning.
