What is a language lab ?
Generally, a lab for any subject matter differs from a regular classroom by providing the Students and Teachers with the tools they need to facilitate hands-on practice with the subject material. Reading is enhanced by incorporating computer-assisted instruction, web-based software, audio and video equipment, and other electronic teaching tools into the language curricula. This applies to all labs including Science labs as well as Language labs.

In a language lab students have to play an active role.
