The Explosive Generation (movie, 1961)

Peter Gifford is a likable, dedicated schoolteacher that teaches a senior life skills class. When student Janet Sommers brings up the topic of sex and dating, he asks students to write questions on the topic, and will cover them in the next class. The parents get wind of what Gifford is about to do, notify the principal, and he warns Peter not to read the questions in class. Gifford decides to go against this and is suspended. The whole student body protests, and the administration gets worried on what to do.
