The document summarizes the impact of the web on computer-assisted language learning (CALL) in three parts. It discusses how the web provided cheaper and easier access to authentic materials and interactions. However, it also notes some problems like unreliable access, lack of support for oral skills, and some students disliking or feeling isolated using the web. It highlights advantages like free access to many sites. Early web-based materials took the form of online textbooks but have since evolved. Virtual classrooms, grammar exercises, quizzes, games, templates, and webquests are now common ways to support language learning online, though access and delivery of multimedia remains imperfect.
