Computer modeling and simulation are changing the nature of scientific investigation, by enabling researchers to pose new kinds of questions and explore phenomena in ways that were not possible just a short time ago. Just as the technological revolution continues to influence the practice of scientific research, it also presents opportunities to change the way that science is taught in the classroom. The Adventures in Modeling Project introduced students and teachers to the process of designing, creating, and analyzing their own models of complex, dynamic systems using StarLogo. Our aims were to educate and motivate teachers to transform the way that they teach science and to engage students in authentic science practice by giving them the tools and the ability to pose, investigate, and answer their own questions. Through model creation, and participation in a variety of off-computer activities, teachers and students learned the science of modeling to develop a deeper understanding of patterns and processes in the world.
