Check out the new search engine http://www.goorulearning.org/#!discover in its beta version for educators. It looks really fascinating - thanks for the tip! Have your students use this instead of the typical Google search and find educationally focused information and resources. And it has a weekly collection spotlight!
I work with teachers and students as an education technology specialist for middle school and serve as the TXDLA K-12 Board Member. My goal is to share innovative and useful information for other educators, as well as catalog my personal finds along the way!
