Ten desiderata for Computer-Assisted Language Learning programs: The example of ELSE

摘要

The article briefly reviews the history of the ELSE program, one of the first Computer-Assisted Language (CALL) programs to use sophisticated error analysis. Its development evokes ten desiderata for such programs (not all of which are found in ELSE). The article, addressed to language teachers and to programmers working with CALL, describes those desiderata and the problems that ensue as one tries to implement them into a specific piece of software.
