About this creative practice
PhET Interactive Simulations is the University of Colorado Boulder project behind free interactive science and mathematics simulations. Credit belongs to the project and its collaborating designers, developers, researchers and contributors, rather than a single author.
PhET describes a research-based design process that includes student interviews and classroom observation. Its simulations let learners vary parameters, manipulate objects and connect visual models with measurements.
