Case studies generate active discussion and decision-making skills. This 50-minute case-study lesson teaches high school and undergraduate students about a fundamental and private aspect of their lives, birth control methods. Students direct their own learning by researching, teaching one another about, and making recommendations about the methods. Students are more likely to apply what they have learned to their own lives after being involved in and practicing decision-making skills during the cases. Because students openly discuss their ideas in relation to the cases, instructors can correct misconceptions about birth control without embarrassing students.
