The mission of the National Center for Case Study Teaching in Science at the University at Buffalo is to promote the development and dissemination of materials and practices for case teaching in the sciences. Their website provides access to an award-winning collection of peer-reviewed case studies.
Access to answer keys and teaching notes requires an approved account and annual paid subscription fee. Access to the cases is free. All new subscribers must first be verified to make sure that they are teachers affiliated with an educational institution.
