CASES Online is a collection of investigative lessons, or "cases," for K-12 and undergraduate science education. Using principles of Problem-Based Learning and Investigative Case-Based Learning (and related student-centered pedagogies), our cases are designed to engage students in exploring the science behind real-world problems. Our cases address a variety of learning objectives across the sciences and mathematics. Although our K-12 cases were designed for use in Georgia and meet our state education standards, we have also included the relevant National Science Education Standards. CASES Online is designed to be used by K-12 and undergraduate science educators. By searching our collection, educators can find cases appropriate to their grade levels, subjects, and topics of interest. In order to download case materials for use in the classroom, educators must first register. While there is no charge to register, download, or use these cases -- we request that all users follow the guidelines outlined under our Terms of Use. Educators are also encouraged to submit cases of their own to our collection. To learn how best to use CASES Online, explore the User Guide; otherwise, begin to transform your classroom by searching for cases.

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.

This flipped case study is suited for general education undergraduate level biology. Students prepare ahead of time for class by viewing a video created by the authors that reviews the basics of nutrition and digestion; in class, students then engage in three activities to further explore aspects of the video's content using specific and concrete examples of diverse foods. During the first part of the case study, students learn information about balanced diets, nutrition and the digestive system. Students apply their knowledge on how food passes through the digestive tract, and how absorption and breakdown of nutrients occur by explaining and presenting the process based on assigned food items. Students are then asked to further apply their knowledge when presented with two scenarios ("mini-cases"), one involving gastric bypass surgery and the other the effects of cholera.
