The War with Mr. Wizzle by Gordon Korman, 1982.
MacDonald Hall hasn’t been the same since Mr. Wizzle came. He’s obsessed with computers and analyzing and categorizing everyone and everything. He uses his computers to analyze the boys’ personalities, making changes to their schedules and activities based on the results. But, no computer could ever understand the wacky and complex personalities of the students at MacDonald Hall.
Mr. Wizzle thinks he can understand everything with his computer, but he doesn’t understand the boys at all. The boys soon get sick of being tested and analyzed and ordered around and told that they should consider changing their last names because the length is too inconvenient for the computer. Even Mr. Sturgeon and the other faculty members are getting fed up with Mr. Wizzle, but they can’t do anything about it because the school’s board of directors are still hoping that Mr. Wizzle will modernize the school.
Meanwhile, the boys’ friends across the street at Miss Scrimmage’s Finishing School for Young Ladies are having personnel problems of their own. Miss Scrimmage’s new athletics teacher, Miss Peabody, used to be a U.S. Marine, and she’s trying to train the girls like they’ve signed up for boot camp. Like the boys, they would do just about anything to get rid of this new nuisance!
What ensues is a series of hi-jinks in the usual spirit of McDonald Hall as the students at each school attempt to drive out the new faculty, but along the way, the kids are forced to acknowledge that they don’t really want anything bad to happen to these new people. It’s not that they’re bad people, they’re just not right for the types of schools and the students they’re trying to teach. Then, a thought occurs to them: Is it possible that Mr. Wizzle and Miss Peabody might be right for . . . each other?
