Teachers TryScience is being built by an outstanding global team. IBM is leading the technology development effort. Our content partners are the New York Hall of Science, a science museum in New York City, which conducts professional development for teachers around the globe, with a focus on project-based learning, and TeachEngineering.org, a collaborative project between faculty, students and teachers associated with five universities and the American Society for Engineering Education, with NSF National Science Digital Library funding. (The universities are University of Colorado at Boulder; Oregon State University; Duke University; Colorado School of Mines; Worcester Polytechnic Institute.) TeachEngineering.org 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 (engineering) come alive in K-12 settings. And finally Teachers TryScience has benefited from a dynamic Advisory Committee, made up of leaders in teacher professional development, that were brought together to provide guidance and input into the site as it developed. This includes our very own Texas Regional Collaboratives! We were incredibly lucky to have the site informed by Carol Fletcher, the Assistant Director of TRC.
