The document discusses Computer Assisted Language Learning (CALL), which uses computers to facilitate language teaching and learning. It notes that CALL allows for permanent contact between teachers and students through forums and tools like word processors, browsers, dictionaries, games, and authoring programs. The teacher's role is to maximize learning by adapting, creating, and facilitating with technological knowledge, while the student's role is to access and study materials at their own pace through virtual platforms. Technology is changing the way people learn by shortening distances with Internet, multimedia, and other communication technologies.
