Professional learning communities (PLCs) are collaborative groups that work together towards common goals to solve problems and share ideas for success. They meet regularly to discuss common ideas and are not meant for complaining. PLCs can collaborate using online tools like Wikispaces for sharing resources, Rubistar for creating common rubrics, and Voki for new student projects. Other tools for collaboration include Google Docs for shared materials, Test Generator for collaborative tests, and shared iTunes libraries for multimedia content. PLCs work to create better content and ensure best practices through online collaboration.
