The New Frontier: Galactic-Scale Star Formation
  The arena of investigation of star formation and its scaling laws is slowly,
but consistently, shifting from the realm of luminous galaxies to that of faint
ones and to sub--galactic regions, as existing and new facilities enable
investigators to probe regions of the combined parameter space of surface
brightness, wavelength, and angular resolution that were inaccessible until a
few years ago. We summarize what has been accomplished, and what remain as
challenges in the field of galactic--scale star formation.
