Educators who are looking for online sites to communicate and collaborate with their peers can register free of charge with Teachade, a site that lets educators share resources, create online learning communities, and connect with colleagues. Teachade is available to K-12 teachers, pre-service teachers, student teachers, and college professors through a free registration process. The site uses Web 2.0 collaboration and social-networking technologies. Teachers can join groups formed around topics such as music, 6th-grade science, supporting educational technology, increasing student and child safety, and so on. Educators also have access to a personal and group calendar and can keep lesson plans or other items in personal “favorites” files.
