Facilitating Acivities

Have you seen our latest video, Facilitating Activities with PhET: An Overview? This video gives an overview of strategies for effective facilitation of K12 activities using PhET. Hear about some examples from fellow teachers. Should students play with PhET before discussions? How do you address questions about the simulation? How do you enable students to explore on their own?

PhET Honored at Wharton-QS Stars Awards 2014: Reimagine Education


We’re excited to announce that we are one of two overall winners of the Wharton-QS Stars Awards 2014: Reimagine Education. PhET, along with PaGamO, the world’s first multi-student social game, shared the honor and a $50,000 prize. Quacquarelli Symonds (QS), publisher of the QS World University Rankings, developed the global Wharton-QS Stars competition to identify the most innovative approaches in higher education to enhance learning and student employability in partnership with The Wharton School SEI Center of the University of Pennsylvania. The global competition received submissions from 427 universities and enterprises from 43 countries with 21 awards judged by a panel of 25 international experts – a who’s who of higher education.

Thanks everyone who has supported PhET!
We couldn’t have won without you.
