Programs and Professional Development

K-12 Educators

The ASP serves K-12 educators who work in the classrooms and those who provide professional development (PD) to teachers. We design and organize diverse programs and services to support the teaching of astronomy as the gateway to science literacy: workshops, publications, bibliographies, PD conferences and networking.

Past programs have included Project ASTRO where we pair teachers with astronomers to share the excitement of astronomy in classrooms around the country, our Galileo Teacher Training Program (GTTP), a two-day professional development workshop, and Cosmos in the Classroom for teachers of college-level introductory astronomy including education workshops about the most popular and populated basic science class in universities across the country.

A teacher affects eternity; [s]he can never tell where [her] his influence stops. — Henry Brooks Adams

Imagination will often carry us to worlds that never were. But without it we go nowhere. — Carl Sagan

Professional Development

TLC Virtual Astronomy Institute

The ASP’s Teacher Learning Center (TLC) introduced the Virtual Astronomy Institute, The Universe in the Classroom in 2020 with a 6 module series covering classroom tested, inquiry-rich astronomy activities designed to engage students in investigations of space science phenomena. Lessons covered support NGSS Three-Dimensional Learning by combining content, crosscutting concepts, and science practices.where teachers actively engage in professional development presenting astronomy content which easily translates into classroom instruction.

We are offering two new sessions in 2021 Fall 2021 Session (Registration ends October 10) and Winter 2022 Session. (Registration ends January 7, 2022).

Thank you to our sponsor, California Space Grant, for supporting our 2021_2022 Season Sessions.



Galileo Project: Pinhole Workshops

In 2017, thanks to funding from the Gordon and Betty Moore Foundation, the ASP expanded its resource and professional development offerings related to the Galileoscope to include a series of in-person and online workshops, articles, and videos to support the use of the Galileoscope in a variety of educational settings.

This has been one of the best PDs ever! I have had so much fun and have been learning so much through “play” and exploration. — Anthony Lund

Professional Development Opportunities for K-12 Teachers

The Teacher Learning Center at the ASP delivers NGSS-aligned professional development to help meet your school district needs. Our hands-on workshops will delight and motivate your teachers to deliver three-dimensional instruction actively engaging and inspiring learners of all ages in space and earth science related phenomena.

Legacy ASP Programs

Project ASTRO

Project ASTRO is a national program that partnered astronomers and teachers in the classroom.

San Francisco Bay Area ASTRO

San Francisco Bay Area ASTRO was a Project ASTRO National Network Site run by the ASP.

Galileo Teacher Training Program

The Galileo Teacher Training Program was a pilot program established during the International Year of Astronomy in 2009, testing a new model of teacher professional development designed to facilitate the teaching of the process of science using Galileo’s iconic observations and other resources. We partnered with the International GTTP program to produce a series of short webinars you may find helpful.

NASA Galileo Educator Network (GEN)

The NASA Galileo Educator Network (GEN) was a NASA funded teacher professional development program managed by the Astronomical Society of the Pacific.
