THE CLASSROOM ASTRONOMER NEWSLETTER

The Newsletter on Astronomy Education for K-12, College, and even Home Schooling science teachers.

The Classroom Astronomer Newsletter  (TCA, or TCAN) is a twice-monthly email newsletter, or as we prefer to call it, an Inbox Magazine, covers many of the same topics as the 2009-2015 magazine, and debuted in May 2021.  The newsletter contains:

  1. Articles on useful educational software.
  2. Regular columns like Astronomical Teachniques–tips and methods to teach specific topics, Connections to the Sky–external sources of resources or programs to help you with your instruction–and The RAP Sheet–items found in scholarly research that you can use now.
  3. Occasional short term columns that have been, or are running, that include a look at the astronomy standards in the NGSS–Next Generation Science Standards–and Astronomy Remotely, Internet observatories you can use.
  4. And sometimes other things!

Designed for use for all levels of astronomy educators, including the pandemically virtual home teachers and home schoolers, and anyone who wants more than just a “Wow, what’s up in the sky?” news briefing. Many items come from the most recent astronomy and astronomy education world conferences! Written by longtime astronomer, journalist and educator Dr. Larry Krumenaker.

Subscribe at https://ClassroomAstronomer.Substack.Com by the month or by the year. Special discount rates for Developing Nation teachers, home school teachers, and science education students (and occasionally others, or all for special events! The free TCA Lite (which began with Issue 9) gives you about half of each Issue.
