One of the advantages to English second language labs is that the student learns English faster and more effectively. ESL labs are frequently used with English language learner, or ELL, programs.
There are many other benefits to exposing an ELL student to a listening lab, one of them being that the student is learning to associate each letter of the alphabet with its unique sound. In addition, the student is able to learn the proper way to pronounce these sounds individually and when those sounds are grouped together in a word.
Another major benefit of these labs is that the student is exposed and fully immersed into an array of English words, allowing his vocabulary to expand at a tremendous rate. Consequently, the student gains the knowledge of how to pronounce a number of words when he's at school or in a social environment.
Another great advantage to an ESL lab is that it vastly improves a student's ability to not only write correctly in English but effectively communicate in the language as well. Lastly, by allowing the student to be part of this popular technique to learn English, his critical thinking skills thrive, and his success in the language flourishes.
