A few months ago, the SETI (Search for Extraterrestrial Intelligence) Institute published their ARISE project at https://agiseti.com. This is a comprehensive curriculum for students all about radio astronomy topics. The topics include labs and lectures on searching for technosignatures, data science in radio astronomy, and radio astronomy fundamentals, as well as an introduction to electromagnetic waves.

While the program is meant for in-person instruction at community colleges, if you are interested in radio astronomy (perhaps with our Discovery Dish and H-line feed), the lecture notes and slides are still a great introduction to the broader topic for anyone.
