Funded by the National Science Foundation, the Learning Matrix collection provides access to about a 1,000 online resources useful to faculty teaching introductory science and mathematics courses as well as providing instructional and pedagogical training. Learning Matrix resources promote inquiry and problem based learning in college mathematics, science, and technology classes. The collection includes simulations, tutorials, research articles, and video footage illustrating excellent teaching techniques. The Learning Matrix is housed at the Eisenhower National Clearinghouse for Science and Mathematics Education (ENC), The Ohio State University, Columbus, OH.

CAREO is a repository of over 3,500 educational materials on various subjects and interactivity levels as part of a larger project to create “a searchable, Web-based collection of multidisciplinary teaching materials for educators” for Alberta and elsewhere.
