Educational technology is the application of technology tools to enhance instruction and extend human capabilities in an educational setting. It includes a wide variety of tools from traditional chalk and blackboards to modern devices like tablets, electronic media, and multimedia. Educational technology also utilizes communication technologies like blogs, podcasts, and social media which are part of the evolving concept of Web 2.0. The power of new technologies lies in how anyone can now create and share information, not just large corporations or specialized individuals.
