Welcome to Windows to the Universe - your portal to discovery! Explore the wealth of information available here to learn about the Earth and Space sciences and related topics in the humanities including mythology, art, poetry, and more.

Windows to the Universe is now offering on-site professional development workshops for teachers. Find out more about this opportunity here. Information about our upcoming workshops and events at the NSTA conference in Indianapolis is available under 2012 on our Teacher Resources/Workshops page.

Windows to the Universe is happy to make available summary results from a survey of Earth and space science educators we conducted from April through August of 2011. Summary survey results are available in two sets:

  • 726 active K-12 US teachers, including responses to 25 questions about demographics, teaching experience, subjects taught, technology use, classroom resources, and more.
  • 329 Windows to the Universe teacher users (307 from the US, 22 International), with responses to more than 50 questions on the above topics, as well as questions regarding their use of Windows to the Universe and associated capabilities.
Windows to the Universe Educator Member Subscribers have free access to these summary results - just login to your account to get access to them. If you're not a member, but would like to get access to both reports, you can join today to get access. Non-members can purchase access to our Survey Summary of Active US K-12 Teachers 2011 through our online store. Summary Survey results from 306 members of the National Earth Science Teachers Association to the same survey (with responses to over 50 questions) are also available to NESTA members on the NESTA website.
