* In DanBrown's book ''TheLostSymbol'', Robert Langdon lectures his symbology class on the secrets of Freemasonry.

* ''Series/MurdochMysteries'': Late in "Big Murder on Campus", Murdoch is in a university classroom giving a lecture on the "applied physics" of execution by hanging. The lecture turns into [[spoiler: a means of pressuring one of the accomplices to a murder into confessing against the other--the soon-to-be-infamous James Gillies]].

* One entire episode of ''[[RODTheTV Read Or Die the TV series]]'' is devoted to a character writing the Exposition Lecture that another character has to give.

* Chapter 5.5 of ''Manga/CentaurNoNayami'' is about a teacher giving a primer on [[VertebrateWithExtraLimbs how evolution went]] on this AlternateUniverse, giving birth to the [[OurCentaursAreDifferent various]] [[OurMermaidsAreDifferent human]] [[FaunsAndSatyrs sub]]-[[WingedHumanoid species]] and how this made racism even a worse problem than in our world.

* In ''{{Mnemosyne}}'', some BackStory about the Tajimamori and the "Fruits of Immortality" are filled in during a lecture at Mishio's high school. Notably, the lecture is on the topic of legends and myths but turns out to consist of [[AllMythsAreTrue pretty accurate truth]].

* ''TheFinal'' opens with a {{high school}} history teacher describing how [[ImperialChina the Han Dynasty]] would sometimes [[CruelMercy leave their defeated enemies alive, disfiguring them]] in order to serve as an example to those who would oppose them.
