CASES Online is a collection of inquiry-based lessons to engage K-12 and undergraduate students in exploring the science behind real-world problems. Through CASES, you can transform your students into motivated investigators, self-directed and life-long learners, critical thinkers and keen problem solvers. Our cases are grounded in Problem-Based Learning (PBL), Investigative Case-Based Learning (ICBL), and related student-centered pedagogies. [more]

Materials for 86 of our cases are now posted and we are working diligently to publish the rest as soon as possible. If you register, we can notify you when new materials are available. Since February 2008, we have published several cases in middle school and high school anatomy/physiology, biology, earth science, physical science, chemistry. View a table of our recent updates.

Search tips: Try a more general search by leaving the subject, grade, and/or keyword blank. Searching by Keyword alone is best (and is not case-sensitive) since many cases can work across disciplines and grade levels. You may also search by author's last name.
