LEARN: Atmospheric Science Explorers (LEARN) began in 1991 with funding from the National Science Foundation (NSF) to help fill the critical need of science teacher professional development. NSF funded two versions of LEARN. The fundamental goal of both LEARN programs was to increase middle school science teacher knowledge of and interest in the atmospheric sciences. The first project began in 1991 and brought 40 middle school and junior high school teachers from California, Colorado, North Carolina, and Texas to the National Center for Atmospheric Research (NCAR) in Boulder, Colorado for three consecutive summers. The second project was funded in 1996 and partnered with 48 teachers from rural schools in Colorado. In addition to the three consecutive summer workshops at NCAR, LEARN staff and scientists from NCAR traveled to the rural Colorado school districts for three additional days of instruction. - https://www.ucar.edu/learn/aboutlrn.htm viewed 12/02/2015.
