This tag indicates that the post is designed (genuinely, or as a parody) to educate or inform the viewer about some subject matter.  This is usually a school subject, like grammar, mathematics, science, etc.  It is also often in the form of a (faux) textbook excerpt.  Many examples (e.g. post #5751468) parody the well-known [[New Horizon]] English textbook. For such material in a book in the scene itself, use [[textbook]].
