About the GTTP

GTTP Selected Resources

The goal of the Galileo Teacher Training Program (GTTP) was to develop and present workshops using Galileo’s telescopic investigations to teach the process of science, problem-solving, and collaboration in an inquiry-based education framework, resulting in an ongoing and evolving teacher professional development opportunity for modeling science process in the classroom.

The Galileo Teacher Training Program was a signature program of the U.S. International Year of Astronomy effort. Go to to learn more about the wide array of IYA programs and events designed to provide astronomy experiences for everyone, in celebration of 400 years of discovery since Galileo’s first observations of the heavens through a telescope.

A Galileo Teacher Training Program workshop focused on four areas:

  • An activity recreating Galileo’s observations of Jupiter’s moons, demonstrating a hands-on, inquiry-based, collaborative approach to scientific investigation, illustrating the process of science;
  • International Year of Astronomy resources and activities;
  • Fundamental concepts to meet curriculum goals;
  • Resources adaptable for use in the classroom.

Many GTTP workshops included the use of activities involving a portable, user-friendly telescope developed for IYA: the Galileoscope. Professional development opportunities utilized the Galileoscope have been developed and are available through the Project ASTRO National Network and other venues, as well as online.

Graduates of the workshop became Galileo Teacher Ambassadors with access to the national network of Galileo Teacher Ambassadors.
