The TeachEngineering digital library is a collaborative project between faculty, students and teachers associated with five founding partner universities , with National Science Foundation funding. The collection continues to grow and evolve with new additions submitted from more than 50 additional contributor organizations , a cadre of volunteer teacher and engineer reviewers , and feedback from teachers who use the curricula in their classrooms.
TeachEngineering is a searchable, web-based digital library collection populated with standards-based engineering curricula for use by K-12 teachers and engineering faculty to make applied science and math come alive through engineering design in K-12 settings. The TeachEngineering collection provides educators with *free* access to a growing curricular resource of activities, lessons, units and living labs. Formation of the TeachEngineering collection was funded primarily under the NSF National Science Digital Library program, aiming to establish a national digital library that constitutes an online network of learning environments and resources for science, technology, engineering and mathematics (STEM) education at all levels. Many other generous sponsors and web partners have enabled its ongoing development and promotion.
