Modern Linguistic labs are known by many names, digital language lab, multimedia language lab, language media center and multimedia learning center to name but a few.
Linguistic labs in general offer the following:
1. Text, images, audio and video can easily be integrated; teachers can alter materials to fit their requirements
2. Learners can record their own voice and play back the recordings, interact with each other and the teacher, and store results
3. Teachers can intervene and control the learners computers via the teacher's console, track of learners work, etc.
4. Self-access for independent learning which includes access to resources outside class
The purpose of a linguistic lab is to involve students to actively participate in language learning exercises and get more practice than otherwise possible in a traditional classroom environment.
Common components in a modern Linguistic Lab:
1. Teacher has a computer with appropriate software for conducting language exercises
2. Teacher and students wear headsets that block outside sounds and disturbances
3. Students have a media player/recorder for listening to audio and recording speech
4. Teacher and student positions are connected via LAN (local area network), in some cases also via separate audio cabling
5. A server computer or a separate storage device is often used to store lesson materials in a digital format
Why use a Linguistic lab in language teaching?
In an average foreign-language class, all students combined speak only 23,5% of the class time (DESI 2006, pg. 48-49).
In a 45-minute long class 23,5% equals approximately 10 ½ minutes. As this number is the speaking time of all students put together, the time each student gets to practice speaking becomes less as class size is increased.
With a Linguistic lab, all students in the class can speak simultaneously without distracting each other regardless of the class size. Without a linguistic lab, in a class of more than 10 students, each student gets less than one minute of speaking practice.
