The past decade has seen remarkable developments in CALL applications on CD-ROMs and over the Internet. Unfortunately, the typical language student using these applications has received little, if any, training toward developing a foundation in how to utilize them effectively for language acquisition. A fundamental quandary in CALL is that learners are increasingly required to take a significant amount of responsibility for their own learning, whether that learning is taking place through the programmed teaching presence in tutorial software or the unstructured spaces of the World Wide Web. They are expected to do this despite the fact that they know little or nothing of how languages are learned compared to an appropriately trained teacher. And they are expected to do this within a domain-that of the computer-that is still relatively unfamiliar as a language-learning environment to most of them.
