Are new approaches to transforming undergraduate learning in science, technology, engineering, and mathematics (STEM) making a difference? If so, how? How do people know? And what next? These are the questions explored in a 1999 report from Project Kaleidoscope, which concluded by making predictions and recommendations for the coming decade. Now that the "coming decade" is here, the author explores how accurate those predictions were and offers some new recommendations for the next decade.
