An interview with the award winning author can be found in About us at Phet VideoPhET provides fun, interactive, research-based simulations of physical phenomena for free. We believe that our research-based approach- incorporating findings from prior research and our own testing- enables students to make connections between real-life phenomena and the underlying science, deepening their understanding and appreciation of the physical world. To help students visually comprehend 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-effect relationships as well as multiple linked representations (motion of the objects, graphs, number readouts, etc.) PhET Interactive Simulations, University of Colorado, http://phet.colorado.edu http://www.merlot.org/merlot/viewMaterial.htm?id=86789 JavaOptics is an ensemble of teaching resources for Physical Optics at university level as part of physics or optics and optometry studies. Some of the resources can also be used by high school teachers or students to illustrate and broaden knowledge on some aspects of physics at this teaching level. The resources may be used either in an ordinary course as support material or as the main working tool in an online Internet course. http://www.merlot.org/merlot/viewMaterial.htm?id=90527 Applet simulates an optical bench, including lenses, mirrors, and aperatures. http://www.merlot.org/merlot/viewMaterial.htm?id=86605 Viperlib is a web-based resource library of images and presentation material illuminating the study of visual perception.All images are given freely by the vision research community and are available for educational, non-profit use only. Registration is required for use (free). http://www.merlot.org/merlot/viewMaterial.htm?id=74604 Demonstrates Fourier Synthesis. Can modulate value of fourier functions and magnitude both graphical and auditory. http://www.merlot.org/merlot/viewMaterial.htm?id=74434 Interative representation of radioactive decay series: Th232, Pu241, U238, U235. http://www.merlot.org/merlot/viewMaterial.htm?id=87977 Physlet problems that relate to optics. http://www.merlot.org/merlot/viewMaterial.htm?id=74728 Fermat's principle states that: The path of a ray of light between two points is the path that minimizes the travel time. The same principle can be applied to different situations. This java applet give you an example of such application. http://www.merlot.org/merlot/viewMaterial.htm?id=80542 A hyperlinked exploration of light, color, optics and vision. http://www.merlot.org/merlot/viewMaterial.htm?id=574129 The Online Optics Tutorial “Staying in Focus” introduces students to some of the basic concepts of geometrical optics in the context of the human eye. It combines interactive animations, videos, slides with graphics, and continuous narration that guides the users along in their studies. Focusing mostly on a conceptual approach to the study of lenses and how they form images, this online learning tool is designed for students to work through on their own. They are explicitly encouraged to play with the interactive animations and to perform virtual experiments, thus becoming active learners rather than passive listeners.
