Preparing Case Learners

Implementing cases

Adopting and Adapting Cases

Finding Cases

SERC: Pedagogy in Action  Using Investigative Cases

• Writing your own case enables you to highlight local concerns, address specific learning issues, or utilize existing resources.

• Adopting and adopting existing cases is a good option for busy teachers.
• Consider NSF’s cyberlearning focus in your instructional design.

• Investigative cases require instructors to assess problem posing and problem solving. Learners must be prepared to defend their conclusions with data and methods that are appropriate.
• Posters offer a way to present questions, data, methods, and conclusions and involve learners in peer review. Case writing should draw on learner’s prior experience and generate a need to know.

• Fibers are unique to specific plants and differ considerably from animal or man-made fibers.
• Plant DNA can provide information useful for identification and geographic location.
• Cotton technology leads to new uses globally.
