To support PhET, visit giveto.colorado.edu/phet-interactive-simulations/?a=9076595 PhET Interactive Simulations is an ongoing effort to provide an extensive suite of simulations to improve the way that physics, chemistry, biology, earth science and math are taught and learned. The simulations are interactive tools that enable students to make connections between real life phenomena and the underly
ing science which explains such phenomena. Our team of scientists, software engineers and science educators use a research-based approach – incorporating findings from prior research and our own testing – to create simulations that support student engagement with and understanding of scientific concepts. In order to help students visually comprehend these concepts, PhET simulations animate what is invisible to the eye through the use of graphics and intuitive controls such as click-and-drag manipulation, sliders and radio buttons. In order to further encourage quantitative exploration, the simulations also offer measurement instruments including rulers, stop-watches, voltmeters and thermometers. As the user manipulates these interactive tools, responses are immediately animated thus effectively illustrating cause-and-effects relationships as well as multiple linked representations (motion of the objects, graphs, number readouts, etc…). To ensure educational effectiveness and usability, all of the simulations are extensively tested and evaluated. These tests include student interviews in addition to actual utilization of the simulations in a variety of settings, including lectures, group work, homework and lab work. Our rating system indicates what level of testing has been completed on each simulation. All PhET simulations are freely available from the PhET website and are easy to use and incorpate into the classroom. They are written in Java and Flash, and can be run using a standard web browser as long as Flash and Java are installed.
