From Free Technology for Teachers: Woices (not voices) is a new, unique service that combines the ideas of podcast conversations with place-marking service of Google Maps.
Mobile Geotagging allows users to post media (photos, video, audio or text) from a mobile phone to a specific point on a map. Flagr allows users to create public, semiprivate, or private maps. Great tool for teachers in many subject areas to enhance learning. For example, students studying habitats or different biological species can take pictures within their community and then send each picture band a description of where the habitat or species was found. In the classroom the teacher opens up the class flagr map and the students then identify the species and discuss why they were found in each particular habitat.
