We present an evaluation of CALL-SLT, a web-based CALL application based on the “translation game” idea, that can be used for practicing fluency in a limited domain. The version tested was configured to teach basic restaurant French to students whose native language is Arabic. Students spent about an hour and a half each working with the system, and explored between five and eight lessons. The focus was on investigating how they interacted with the system and what they learned most effectively.
