PBS has formally launched a comprehensive new web site for K-12 educators, called "PBS Teachers." In production for more than a year, the site is the front door for all educational resources and services that PBS offers, including thousands of free lesson plans, teacher professional development opportunities, videos, blogs, and more. It also provides information about effective ways to use media and technology in school or home-based learning environments. Among the site's features are a new blog, called "Media Infusion," that will showcase ideas for (and encourage conversations about) using media and technology in the classroom; thousands of free, standards-based lesson plans, classroom activities, and interactive resources, organized by subject, grade level, and curriculum topic; hundreds of curriculum resources from local PBS stations, forming a local-national search that combines the best educational resources from around the country; dedicated areas for early childhood educators, library media specialists, and technology coordinators; on-demand streaming video from selected PBS programs; a "Shop for Teachers" feature for purchasing video programs; and online professional development opportunities from PBS TeacherLine for graduate credit and recertification. Also coming this summer: advanced personalization features that will enable educators to bookmark, annotate, and share the resources they find.
