See Tim Holt on El Paso Independent School District’s (EPISD) Digital Discoveries show how they use PhET.

PhET, December 9, 2011: “In this segment, we look at some amazing online simulations for science and math classes: PhET simulations. These are great for use on IWBs as well as for reinforcing concepts. We sample a few random PhET simulations, including John Travoltage!

Thanks Tom for the Shout Out!

Have you seen our latest video Using PhET in Lecture: Going Beyond Demos?

See how to use PhET simulations in powerful ways that engage a whole class in a large lecture setting. See examples of how you can incorporate clickers and other instructional techniques to deliver engaging interactive lecture demonstrations that will make maximum impact on student learning.

On January 10th, 2012, the United States Computer Emergency Readiness Team (US-CERT) released a bulletin regarding security issues with Java. One of the recommendations in this bulletin is to disable Java in web browsers. In many cases, this will prevent running PhET simulations directly from the PhET web site.

If you are a user of PhET simulations, are currently running Java 7 and want to still be able to use PhET simulations, we recommend that you take the following steps:

• Upgrade to the latest version of Java.
• Disable Java from running in web browsers. Note that this will prevent the “Run Now” option from launching simulations from the PhET site. This article has information about how to perform this operation.
• Run the simulations by downloading them via the “Download” button, and then running locally.

PhET will continue to monitor the situation surrounding Java security issues and will send out an update when the problems are fully resolved.

If you have questions or concerns regarding this, please contact us at [email protected].

Thank you for using and supporting PhET Interactive Simulations!

The University of Colorado Office of Information Technology will be performing a scheduled system reboot of the PhET server on Thursday, January 10 at 11:00 PM Mountain Standard Time. During this time, PhET (http://phet.colorado.edu) will experience periods of unavailability. We expect that the outage will last only 10 minutes and that we will be back online very quickly. However, if you experience issues, please e-mail the PhET Help Desk at [email protected].

Thanks for your patience during our system maintenance.

Happy New Year!

And thank you to all those who pledged their support to PhET in 2012. We are looking forward to an exciting 2013 with new simulations as well as making our more popular sims tablet compatible.
