Prisoner of Azkaban was, at the time of publication, the series' longest book. The increasing plot complexity necessitated a looser adaptation of the book's finer plot lines and back-story. The film opens with Harry using magic to light his wand in short bursts, whereas in the same scene in the book, he uses a torch/flashlight, as performing magic outside the wizard world is illegal for wizards under the age of seventeen. The connection between Harry's parents and the Marauder's Map is only briefly mentioned,  as is Remus Lupin 's association to both the map and James Potter.  Additionally, it was never mentioned who the Marauders were or who the nicknames Moony, Wormtail, Padfoot, and Prongs referred to. Some exposition was removed for dramatic effect: both the Shrieking Shack and Scabbers the rat are mentioned only very briefly in the film, while they receive a more thorough coverage in the novel.  Most of Sirius Black 's back story is also cut, with no mention of the manner of his escape from Azkaban .  Only the first Quidditch game was kept in the film, due to its importance to the storyline; the second (Gryffindor/Ravenclaw) and third (Gryffindor/Slytherin) were cut. Thus, Harry receives the Firebolt at the film's end, while in the book he receives it anonymously at Christmas and it is confiscated for a few weeks to be checked for possible jinxes by Professor Flitwick and Madam Hooch.
Students examine two text selections that feature a boggart—a shape-shifter that turns into whatever one fears most—from Harry Potter and the Prisoner of Azkaban and Harry Potter and the Order of the Phoenix , books three and five of the series. In Class 1 , students interpret and evaluate the two excerpts to consider the symbolic value of the boggart, its connection to character development, and similarities between the text and their own lives. In Class 2 , students use their literary analyses from Class 1 and engage in a writing workshop to produce short essays. Students prepare drafts, obtain feedback from their peers, consider the feedback, and then rewrite the draft to produce final essays.
