"A 2013 Gallup poll of 500,000 students in grades five through 12 found that nearly eight in 10 elementary students were “engaged” with school, that is, attentive, inquisitive, and generally optimistic. By high school, the number dropped to four in 10. A 2015 follow-up study found that less than a third of 11th-graders felt engaged. When Gallup asked teens in 2004 to select the top three words that describe how they feel in school from a list of 14 adjectives, “bored” was chosen most often, by half the students. “Tired” was second, at 42 percent. Only 2 percent said they were never bored. The evidence suggests that, on a daily basis, the vast majority of teenagers seriously contemplate banging their heads against their desks."
