Humor can be defined as attempting to create positive feelings of amusement or laughter in others. Humor should be used as a teaching technique because it makes lectures more interesting and encourages student participation and expression of opinions. Understanding humor involves both hemispheres of the brain, with the left hemisphere identifying details in jokes and the right hemisphere comprehending and appreciating humor. While humor varies depending on the type of class, it should allow students to feel part of the class and can help reach nervous students and encourage critical thinking.
