Wolfram Education Portal

Wolfram has long been a trusted name in education—as the makers of Mathematica, Wolfram|Alpha, and the Wolfram Demonstrations Project, they have created some of the most dynamic teaching and learning tools available. They are pleased to offer the best of all of their technologies to you here in the Wolfram Education Portal, organized by course. In the portal you’ll find a dynamic textbook, lesson plans, widgets, interactive Demonstrations, and more built by Wolfram education experts. You can take a look at the types of materials they offer, but to get full access to all materials, you need to sign up for a free account. The portal is currently in Beta, so feel free to explore the materials. This has been added to Research Resources Subject Tracer™ Information Blog.
