Dr. John M. Keller's research focuses around astronomy education. As Director of Fiske Planetarium, a 207-seat digital dome facility on the University of Colorado Boulder campus, Keller is actively involved in studying science learning in immersive environments. Keller also serves as a PI for RECON, the Research and Education Collaborative Occultation Network, an NSF-funded citizen science astronomy research project involving over 50 secondary schools across the western United States to measure trans-Neptunian Objects. Keller is also playing a leading role in studying longitudinal impacts of providing mentored summer research experiences to aspiring K-12 teachers on their classroom practices and retention in teaching.
