Fully online courses and degree programs are popular with students today. It is important that these courses provide the same rigor and value of a traditional learning experience in a face-to-face classroom in order to ensure mastery of concepts and learning objectives. Online classes typically have suffered due to a lack of hands-on experiences…

Cosmic expansion is an important concept in astronomy. For ease of understanding, astronomers generally draw an analogy between cosmic expansion and the expansion of a spherical surface in 3D space. This study theoretically and experimentally investigates the laws governing the motion of particles on the surface of a balloon during expansion.…

The most recent data on stars orbiting Sagittarius A*, the black hole at the center of the Milky Way galaxy, have been used in an experiment undertaken by second-year university students to determine the distance R[theta] to the center of the galaxy. Students applied each of Kepler's 17th-century laws, in turn, to 21st-century data. The…

Over the last decade, remote instruments have become widely used in astronomy. Educational applications are more recent. This paper describes a program to bring radio astronomy into the undergraduate classroom through the use of a remote research-grade radio telescope, the MIT Haystack Observatory 37 m telescope. We examine the effectiveness of…
