ORLANDO — PBS and WGBH today announced PBS LearningMedia, the next generation of the PBS Digital Learning Library. It’ll be a digital media platform to “help re-imagine classroom learning, transform teaching, and more creatively engage students,” the network said in a statement. “Digital media content – so pervasive in the lives of children – has the potential to dramatically change the way students learn and participate in a global society,” PBS President Paula Kerger said. Including content from more than 55 member stations, independent producers and public institution partners, the first phase of development will combine existing infrastructure models from the PBS Digital Learning Library (formerly EDCAR) with local services from WGBH’s Teachers’ Domain and its partners, WNET/New York and Kentucky Educational Television (KET). PBS LearningMedia will be offered in two tiers from local member stations: a free version available to every teacher, and a premium service with features such as bulk registrations, analytics, integration with assessments, and credit-bearing professional development courses.
